Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	Summary of Significant Accounting Policies
	Principles of Consolidation:    The consolidated financial statements include the accounts of Motorola Solutions, Inc. (the “Company” or “Motorola Solutions”) and all controlled subsidiaries. All intercompany transactions and balances have been eliminated.
	The consolidated financial statements as of December 31, 2014 and 2013 and for the years ended December 31, 2014, 2013 and 2012, include, in the opinion of management, all adjustments (consisting of normal recurring adjustments and reclassifications) necessary to present fairly the Company's consolidated financial position, results of operations, statements of comprehensive income, statement of stockholder's equity, and cash flows for all periods presented.
	Use of Estimates: The preparation of financial statements in conformity with United States ("U.S.") Generally Accepted Accounting Principles ("GAAP") requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.
	Revenue Recognition: Net sales consist of a wide range of activities including the delivery of stand-alone equipment or services, custom design and installation over a period of time, and bundled sales of equipment, software and services. The Company enters into revenue arrangements that may consist of multiple deliverables of its products and services due to the needs of its customers. The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable, and collectability of the sales price is reasonably assured. The Company recognizes revenue from the sale of equipment, equipment containing both software and nonsoftware components that function together to deliver the equipment’s essential functionality, and services in accordance with general revenue recognition accounting principles. The Company recognizes revenue in accordance with software accounting guidance for the following types of sales transactions: (i) standalone sales of software products or software upgrades, (ii) standalone sales of software maintenance agreements, and (iii) sales of software bundled with equipment where the software is not essential to the functionality of that equipment.
	Products
	For equipment sales, in addition to the criteria mentioned above, revenue recognition occurs when title and risk of loss has transferred to the customer, objective evidence exists that customer acceptance provisions have been met, no significant obligations remain and allowances for discounts, price protection, returns and customer incentives can be reliably estimated. Recorded revenues are reduced by these allowances. The Company bases its estimates of these allowances on historical experience taking into consideration the type of products sold, the type of customer, and the specific type of transaction in each arrangement. Where customer incentives cannot be reliably estimated, the Company defers revenue until the incentive has been finalized with the customer. The Company includes shipping charges billed to customers in net revenue, and includes the related shipping costs in cost of sales.
	The Company sells software and equipment obtained from other companies. The Company establishes its own pricing and retains related inventory risk, is the primary obligor in sales transactions with customers, and assumes the credit risk for amounts billed to customers. Accordingly, the Company generally recognizes revenue for the sale of products obtained from other companies based on the gross amount billed.
	Long-Term Contracts
	For long-term contracts that involve customization of equipment and/or software, the Company generally recognizes revenue using the percentage of completion method based on the percentage of costs incurred to date compared to the total estimated costs to complete the contract (“Estimated Costs at Completion”). The components of estimated costs to complete a contract and management’s process for reviewing Estimated Costs at Completion and progress toward completion is discussed further below. Contracts may be combined or segmented in accordance with the applicable criteria under contract accounting principles. In certain instances, when revenues or costs associated with long-term contracts cannot be reliably estimated or the contract contains other inherent uncertainties, revenues and costs are deferred until the project is complete and customer acceptance is obtained.
	Total Estimated Costs at Completion include direct labor, material and subcontracting costs. Due to the nature of the work required to be performed under many of the Company’s long-term contracts, determining Estimated Costs at Completion is complex and subject to many variables. The Company has a standard and disciplined quarterly Estimated Costs at Completion process in which management reviews the progress and performance of open contracts. As part of this process, management reviews information including, but not limited to, any outstanding key contract matters, progress towards completion, the project schedule, identified risks and opportunities, and the related changes in estimates of revenues and costs. The risks and opportunities include management's judgment about the ability and cost to achieve the project schedule, technical requirements, and other contract requirements. Management must make assumptions and estimates regarding labor productivity and availability, the complexity of the work to be performed, the availability of materials, and performance by subcontractors, among other variables. Based on this analysis, any quarterly adjustments to net sales, cost of sales, and the related impact to operating income are recorded as necessary in the period they become known. These adjustments may result from positive project performance, and may result in an increase in operating income during the performance of individual contracts. Likewise, these adjustments may result in a decrease in operating income if Estimated Costs at Completion increase. Changes in estimates of net sales or cost of sales could affect the profitability of one or more of our contracts. The impact on Operating earnings as a result of changes in Estimated Costs at Completion was not significant for the years 2014, 2013, and 2012. When estimates of total costs to be incurred on a contract exceed total estimates of revenue to be earned, a provision for the entire loss on the contract is recorded in the period the loss is determined.
	Hardware and Software Services Support
	Revenue under equipment and software maintenance agreements, which do not contain specified future software upgrades, is recognized ratably over the contract term as services are performed.
	Software and Licenses
	Revenue from pre-paid perpetual licenses is recognized at the inception of the arrangement, presuming all other relevant revenue recognition criteria are met. Revenue from non-perpetual licenses or term licenses is recognized ratably over the period that the licensee uses the license.
	Multiple-Element Arrangements
	Arrangements with customers may include multiple deliverables, including any combination of products, services and software. These multiple-element arrangements could also include an element accounted for as a long-term contract coupled with other products, services and software. For multiple-element arrangements that include products containing software that functions together with the equipment to deliver its essential functionality, undelivered software elements that relate to the product's essential software, and undelivered non-software services deliverables are separated into more than one unit of accounting when: (i) the delivered element(s) have value to the customer on a stand-alone basis and (ii) delivery of the undelivered element(s) is probable and substantially in the control of the Company.
	In these arrangements, the Company allocates revenue to all deliverables based on their relative selling prices. The Company uses the following hierarchy to determine the selling price to be used for allocating revenue to deliverables: (i) vendor-specific objective evidence of fair value (“VSOE”), (ii) third-party evidence of selling price (“TPE”), and (iii) best estimate of selling price (“ESP”).
	The Company determines VSOE based on its normal pricing and discounting practices for the specific product or service when that same product or service is sold separately. In determining VSOE, the Company requires that a substantial majority of the selling prices for a product or service fall within a reasonably narrow pricing range, generally evidenced by the pricing rates of approximately 80% of such historical stand-alone transactions falling within plus or minus 15% of the median rate.
	When VSOE does not exist, the Company attempts to determine TPE based on competitor prices for similar deliverables when sold separately. Generally, the Company's go-to-market strategy for many of its products differs from that of its competitors and its offerings contain a significant level of customization and differentiation such that the comparable pricing of products with similar functionality sold by other companies cannot be obtained. Furthermore, the Company is unable to reliably determine what similar competitor products’ selling prices are on a stand-alone basis. Therefore, the Company is typically not able to determine TPE.
	When both VSOE and TPE are unavailable, the Company uses ESP. The Company determines ESP by: (i) collecting all reasonably available data points including sales, cost and margin analysis of the product, and other inputs based on its normal pricing and discounting practices, (ii) making any reasonably required adjustments to the data based on market and Company-specific factors, and (iii) stratifying the data points, when appropriate, based on customer, magnitude of the transaction and sales volume.
	The Company also considers the geographies in which the products or services are sold, major product and service groups, customer classification, and other environmental or marketing variables in determining VSOE, TPE, and ESP.
	Once elements of an arrangement are separated into more than one unit of accounting, revenue is recognized for each separate unit of accounting based on the nature of the revenue as described above.
	The Company's arrangements with multiple deliverables may also contain one or more software deliverables that are subject to software revenue recognition guidance. The revenue for these multiple-element arrangements is allocated to the software deliverable(s) and the non-software deliverable(s) based on the relative selling prices of all of the deliverables in the arrangement using the fair value hierarchy outlined above. In circumstances where the Company cannot determine VSOE or TPE of the selling price for any of the deliverables in the arrangement, ESP is used for the purpose of allocating the arrangement consideration between software and non-software deliverables.
	The Company allocates arrangement consideration to multiple software or software-related deliverables, including the sale of software upgrades or software support agreements to previously sold software, in accordance with software accounting guidance. For such arrangements, revenue is allocated to the deliverables based on the relative fair value of each element, and fair value is determined using VSOE. Where VSOE does not exist for the undelivered software element, revenue is deferred until either the undelivered element is delivered or VSOE is established, whichever occurs first. When the final undelivered software element is post contract support, service revenue is recognized on a ratable basis over the remaining service period. When VSOE of a delivered element has not been established, but VSOE exists for the undelivered elements, the Company uses the residual method to recognize revenue when the fair value of all undelivered elements is determinable. Under the residual method, the fair value of the undelivered elements is deferred and the remaining portion of the arrangement consideration is allocated to the delivered elements and is recognized as revenue.
	Cash Equivalents:    The Company considers all highly-liquid investments purchased with an original maturity of three months or less to be cash equivalents. Restricted cash was $63 million at both December 31, 2014 and December 31, 2013.
	Sigma Fund:    Prior to December 2013, the Company invested most of its U.S. dollar-denominated cash in a fund (the “Sigma Fund”) which was managed by independent investment management firms under specific investment guidelines restricting the type of investments held and their time to maturity. In December 2013, the Company completed the liquidation of the Sigma Fund and migrated the international U.S. dollar denominated cash to a U.S. dollar cash pool invested primarily in U.S. dollar prime money market funds. These money market funds are classified as Cash and cash equivalents within the consolidated balance sheet as of both December 31, 2014 and 2013
	Investments:    Investments in equity and debt securities classified as available-for-sale are carried at fair value. When applicable, debt securities classified as held-to-maturity are carried at amortized cost. Equity securities that are restricted for more than one year or that are not publicly traded are carried at cost. Certain investments are accounted for using the equity method if the Company has significant influence over the issuing entity.
	The Company assesses declines in the fair value of investments to determine whether such declines are other-than-temporary. This assessment is made considering all available evidence, including changes in general market conditions, specific industry and individual company data, the length of time and the extent to which the fair value has been less than cost, the financial condition and the near-term prospects of the entity issuing the security, and the Company’s ability and intent to hold the investment until recovery. Other-than-temporary impairments of investments are recorded to Other within Other income (expense) in the Company’s consolidated statements of operations in the period in which they become impaired.
	Inventories:    Inventories are valued at the lower of average cost (which approximates cost on a first-in, first-out basis) or market (net realizable value or replacement cost).
	Property, Plant and Equipment:    Property, plant and equipment are stated at cost less accumulated depreciation. Depreciation is recorded on a straight-line basis, based on the estimated useful lives of the assets (buildings and building equipment, five to forty years; machinery and equipment, two to ten years) and commences once the assets are ready for their intended use.
	Goodwill and Intangible Assets:    Goodwill is assessed for impairment at least annually at the reporting unit level. The Company performs its annual assessment of goodwill for impairment in the fourth quarter of each fiscal year. The annual assessment is performed using the two-step goodwill test which may also include the optional qualitative assessment to determine whether it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount prior to performing the two-step goodwill impairment test. If this is the case, the two-step goodwill impairment test is required. If it is more-likely-than-not that the fair value of a reporting unit is greater than its carrying amount, the two-step goodwill impairment test is not required.
	If the two-step goodwill impairment test is performed, first, the fair value of each reporting unit is compared to its book value. If the fair value of the reporting unit is less than its book value, the Company performs a hypothetical purchase price allocation based on the reporting unit's fair value to determine the fair value of the reporting unit's goodwill. Fair value is determined using a combination of present value techniques and market prices of comparable businesses.
	Intangible assets are amortized on a straight line basis over their respective estimated useful lives ranging from one to ten years. The Company has no intangible assets with indefinite useful lives.
	Impairment of Long-Lived Assets: Long-lived assets, which include intangible assets, held and used by the Company, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of assets may not be recoverable. The Company evaluates recoverability of assets to be held and used by comparing the carrying amount of an asset (group) to future net undiscounted cash flows to be generated by the asset (group). If an asset (group) is considered to be impaired, the impairment to be recognized is equal to the amount by which the carrying amount of the asset (group) exceeds the asset's (group's) fair value calculated using a discounted future cash flows analysis or market comparables. Assets held for sale, if any, are reported at the lower of the carrying amount or fair value less cost to sell.
	Income Taxes: Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities from a change in tax rates is recognized in the period that includes the enactment date.
	Deferred tax assets are reduced by valuation allowances if, based on the consideration of all available evidence, it is more-likely-than-not that all or some portion of the deferred tax asset will not be realized. Significant weight is given to evidence that can be objectively verified. The Company evaluates deferred tax assets on a quarterly basis to determine if valuation allowances are required by considering available evidence. Deferred tax assets are realized by having sufficient future taxable income to allow the related tax benefits to reduce taxes otherwise payable. The sources of taxable income that may be available to realize the benefit of deferred tax assets are future reversals of existing taxable temporary differences, future taxable income, exclusive of reversing temporary differences and carryforwards, taxable income in carry-back years and tax planning strategies that are both prudent and feasible.
	The Company recognizes the effect of income tax positions only if sustaining those positions is more-likely-than-not. Changes in recognition or measurement are reflected in the period in which a change in judgment occurs. The Company records interest related to unrecognized tax benefits in Interest expense and penalties in Selling, general and administrative expenses in the Company’s consolidated statements of operations.
	Sales and Use Taxes: The Company records taxes imposed on revenue-producing transactions, including sales, use, value added and excise taxes, on a net basis with such taxes excluded from revenue.
	Long-term Receivables:    Long-term receivables include trade receivables where contractual terms of the note agreement are greater than one year. Long-term receivables are considered impaired when management determines collection of all amounts due according to the contractual terms of the note agreement, including principal and interest, is no longer probable. Impaired long-term receivables are valued based on the present value of expected future cash flows discounted at the receivable’s effective interest rate, or the fair value of the collateral if the receivable is collateral dependent. Interest income and late fees on impaired long-term receivables are recognized only when payments are received. Previously impaired long-term receivables are no longer considered impaired and are reclassified to performing when they have performed under a workout or restructuring for four consecutive quarters.
	Foreign Currency:    Certain of the Company’s non-U.S. operations use their respective local currency as their functional currency. Those operations that do not have the U.S. dollar as their functional currency translate assets and liabilities at current rates of exchange in effect at the balance sheet date and revenues and expenses using rates that approximate those in effect during the period. The resulting translation adjustments are included as a component of Accumulated other comprehensive loss in the Company’s consolidated balance sheets. For those operations that have the U.S. dollar as their functional currency, transactions denominated in the local currency are measured in U.S. dollars using the current rates of exchange for monetary assets and liabilities and historical rates of exchange for nonmonetary assets. Gains and losses from remeasurement of monetary assets and liabilities are included in Other within Other income (expense) within the Company’s consolidated statements of operations.
	Derivative Instruments:    Gains and losses on hedges of existing assets or liabilities are marked-to-market and the result is included in Other within Other income (expense) within the Company’s consolidated statements of operations. Certain financial instruments are used to hedge firm future commitments or forecasted transactions.  Gains and losses pertaining to those instruments that qualify for hedge accounting are deferred until such time as the underlying transactions are recognized and subsequently recognized in the same line within the consolidated statements of operations as the hedged item. Gains and losses pertaining to those instruments that do not qualify for hedge accounting are recorded immediately in Other income (expense) within the consolidated statements of operations.
	Earnings Per Share:    The Company calculates its basic earnings (loss) per share based on the weighted-average effect of all common shares issued and outstanding. Net earnings (loss) attributable to Motorola Solutions, Inc. is divided by the weighted average common shares outstanding during the period to arrive at the basic earnings (loss) per share. Diluted earnings (loss) per share is calculated by dividing net earnings (loss) attributable to Motorola Solutions, Inc. by the sum of the weighted average number of common shares used in the basic earnings (loss) per share calculation and the weighted average number of common shares that would be issued assuming exercise or conversion of all potentially dilutive securities, excluding those securities that would be anti-dilutive to the earnings (loss) per share calculation. Both basic and diluted earnings (loss) per share amounts are calculated for earnings (loss) from continuing operations and net earnings attributable to Motorola Solutions, Inc. for all periods presented.
	Share-Based Compensation Costs:    The Company has incentive plans that reward employees with stock options, stock appreciation rights, restricted stock and restricted stock units, as well as an employee stock purchase plan. The amount of compensation cost for these share-based awards is generally measured based on the fair value of the awards as of the date that the share-based awards are issued and adjusted to the estimated number of awards that are expected to vest. The fair values of stock options and stock appreciation rights are generally determined using a Black-Scholes option pricing model which incorporates assumptions about expected volatility, risk free rate, dividend yield, and expected life. Compensation cost for share-based awards is recognized on a straight-line basis over the vesting period.
	Retirement Benefits:    The Company records annual expenses relating to its pension benefit and postretirement plans based on calculations which include various actuarial assumptions, including discount rates, assumed asset rates of return, compensation increases, turnover rates and health care cost trend rates. The Company reviews its actuarial assumptions on an annual basis and makes modifications to the assumptions based on current rates and trends. The effects of the gains, losses, and prior service costs and credits are amortized either over the average service life or over the average remaining lifetime of the participants, depending on the number of active employees in the plan. The funded status, or projected benefit obligation less plan assets, for each plan, is reflected in the Company’s consolidated balance sheets using a December 31 measurement date.
	Advertising Expense:    Advertising expenses, which are the external costs of marketing the Company’s products, are expensed as incurred. Advertising expenses were $61 million, $76 million and $80 million for the years ended December 31, 2014, 2013 and 2012, respectively.
	Recent Accounting Pronouncements: In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers." This new standard will replace most existing revenue recognition guidance in U.S. GAAP. The core principle of the ASU is that an entity should recognize revenue for the transfer of goods or services equal to the amount it expects to receive for those goods and services. The ASU requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and estimates, and changes in those estimates. The ASU will be effective for the Company beginning January 1, 2017, and allows for both retrospective and modified-retrospective methods of adoption. The Company is in the process of determining the method of adoption it will elect and is currently assessing the impact of this ASU on its consolidated financial statements and footnote disclosures.

	During the year ended December 31, 2012, the Company issued an aggregate face principal amount of $750 million of 3.750% Senior Notes due 2022 (the “2022 Senior Notes”).  The Company also redeemed $400 million aggregate principal amount outstanding of its 5.375% Senior Notes due November 2012 for an aggregate purchase price of approximately $408 million.  After accelerating the amortization of debt issuance costs and debt discounts, the Company recognized a loss of approximately $6 million related to this redemption within Other income (expense) in the consolidated statements of operations.  This debt was repurchased with a portion of the proceeds from the issuance of the 2022 Senior Notes.
	Aggregate requirements for long-term debt maturities during the next five years are as follows: 2015—$4 million; 2016—$5 million; 2017—$5 million; 2018—$6 million; and 2019—$11 million.
	Credit Facilities
	As of December 31, 2014, the Company had a $2.1 billion unsecured syndicated revolving credit facility (the “2014 Motorola Solutions Credit Agreement”) scheduled to mature on May 29, 2019 which replaced the previous $1.5 billion unsecured syndicated revolving credit facility (the “2011 Motorola Solutions Credit Agreement”). The Company must comply with certain customary covenants, including maximum leverage ratio as defined in the 2014 Motorola Solutions Credit Agreement. The Company is no longer subject to a minimum interest coverage covenant under the new facility. The Company was in compliance with its financial covenants as of December 31, 2014. The Company did not borrow under the 2011 Motorola Solutions Credit Agreement or the 2014 Motorola Solutions Credit Agreement during the twelve months ended December 31, 2014.
	As of December 31, 2014, the Company had a letter of credit sub-limit of $450 million under the 2014 Motorola Solutions Credit Agreement. No letters of credit were issued under the revolving credit facility as of December 31, 2014.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Risk Management	Risk Management
	Foreign Currency Risk
	The Company uses financial instruments to reduce its overall exposure to the effects of currency fluctuations on cash flows. The Company’s policy prohibits speculation in financial instruments for profit on exchange rate price fluctuations, trading in currencies for which there are no underlying exposures, or entering into transactions for any currency to intentionally increase the underlying exposure. Instruments that are designated as part of a hedging relationship must be effective at reducing the risk associated with the exposure being hedged and are designated as part of a hedging relationship at the inception of the contract. Accordingly, changes in the market values of hedge instruments must be highly correlated with changes in market values of the underlying hedged items both at the inception of the hedge and over the life of the hedge contract.
	The Company’s strategy related to foreign exchange exposure management is to offset the gains or losses on the financial instruments against gains or losses on the underlying operational cash flows or investments based on the Company's assessment of risk. The Company enters into derivative contracts for some of its non-functional currency cash, receivables, and payables, which are primarily denominated in major currencies that can be traded on open markets. The Company typically uses forward contracts and options to hedge these currency exposures. In addition, the Company enters into derivative contracts for some forecasted transactions, which are designated as part of a hedging relationship if it is determined that the transaction qualifies for hedge accounting under the provisions of the authoritative accounting guidance for derivative instruments and hedging activities. A portion of the Company’s exposure is from currencies that are not traded in liquid markets and these are addressed, to the extent reasonably possible, by managing net asset positions, product pricing and component sourcing.
	At December 31, 2014, the Company had outstanding foreign exchange contracts totaling $628 million, compared to $837 million outstanding at December 31, 2013. Management believes that these financial instruments should not subject the Company to undue risk due to foreign exchange movements because gains and losses on these contracts should generally offset losses and gains on the underlying assets, liabilities and transactions, except for the ineffective portion of the instruments, which is charged to Other within Other income (expense) in the Company’s consolidated statements of operations.
	The following table shows the five largest net notional amounts of the positions to buy or sell foreign currency as of December 31, 2014 and the corresponding positions as of December 31, 2013:
		Notional Amount
	Net Buy (Sell) by Currency	2014			2013

	Norwegian Krone	(90		)	(95		)
	Australian Dollar	(42		)	(17		)
	British Pound	34			257
	Interest Rate Risk
	As part of its liability management program, one of the Company's European subsidiaries has outstanding interest rate agreements (“Interest Agreements”) relating to Euro-denominated loans. The interest on the Euro-denominated loans is variable. The Interest Agreements change the characteristics of interest rate payments from variable to maximum fixed-rate payments. The Interest Agreements are not accounted for as a part of a hedging relationship and, accordingly, the changes in the fair value of the Interest Agreements are included in Other income (expense) in the Company's consolidated statements of operations. The weighted average fixed rate payment on the Interest Agreements for the year ended December 31, 2014 was 4.02%. The fair value of the Interest Agreements was a liability position of $2 million at December 31, 2014, compared to a liability position of $3 million at December 31, 2013.
	Counterparty Risk
	The use of derivative financial instruments exposes the Company to counterparty credit risk in the event of nonperformance by counterparties. However, the Company’s risk is limited to the fair value of the instruments when the derivative is in an asset position. The Company actively monitors its exposure to credit risk. At present time, all of the counterparties have investment grade credit ratings. The Company is not exposed to material credit risk with any single counterparty. As of December 31, 2014, the Company was exposed to an aggregate credit risk of approximately $1 million with all counterparties.

	Total income tax expense (benefit)	$	(465	)		$	(59	)		$	211
	Deferred tax balances that were recorded within Accumulated other comprehensive loss in the Company’s consolidated balance sheets resulted from retirement benefit adjustments, currency translation adjustments, net gains (losses) on derivative instruments and fair value adjustments to available-for-sale securities. The adjustments were $286 million, $606 million and $(272) million for the years ended December 31, 2014, 2013 and 2012, respectively.
	The Company evaluates its permanent reinvestment assertions with respect to foreign earnings at each reporting period and, except for certain earnings that the Company intends to reinvest indefinitely due to the capital requirements of the foreign subsidiaries or due to local country restrictions, accrues for the U.S. federal and foreign income tax applicable to the earnings. During the fourth quarter of 2014, the Company reassessed its unremitted earnings position and concluded that certain of its non-U.S. subsidiaries’ earnings were permanently reinvested overseas. The Company intends to utilize these offshore earnings for working capital needs in its international operations. During 2014, the Company recorded a net tax benefit of $19 million related to reversals of deferred tax liabilities related to undistributed foreign earnings due to the change in permanent reinvestment assertion. During 2013, the Company reassessed its unremitted earnings position concluding that certain of its non-U.S. subsidiaries' earnings were permanently reinvested overseas. As a result, the Company recognized a tax benefit of $25 million during 2013 for the reversal of related deferred tax liabilities.
	Undistributed earnings that the Company intends to reinvest indefinitely, and for which no income taxes have been provided, aggregate to $1.5 billion December 31, 2014. The Company currently has no plans to repatriate the foreign earnings permanently reinvested and therefore, the time and manner of repatriation is uncertain.  If circumstances change and it becomes apparent that some or all of the permanently reinvested earnings will be remitted to the U.S. in the foreseeable future, an additional income tax charge may be necessary; however, given the uncertain repatriation time and manner at December 31, 2014, it is not practicable to estimate the amount of any additional income tax charge on permanently reinvested earnings.  On a cash basis, these repatriations from the Company's non-U.S. subsidiaries could require the payment of additional taxes. The portion of earnings not reinvested indefinitely may be distributed without an additional charge given the U.S. federal and foreign income tax accrued on undistributed earnings and the utilization of available foreign tax credits. At December 31, 2014, the Company has approximately $400 million of foreign earnings not considered permanently reinvested and which may be repatriated without an additional tax charge.
	In 2013, the Company reorganized certain of its non-U.S. subsidiaries under a holding company structure in order to facilitate the efficient movement of non-U.S. cash and provide a platform to fund foreign investments, such as potential acquisitions and capital expenditures. During 2013, the Company recognized a $337 million tax benefit associated with the excess tax credits relating to the earnings of certain non-U.S. subsidiaries reorganized under the holding company structure.
	Differences between income tax expense (benefit) computed at the U.S. federal statutory tax rate of 35% and income tax expense (benefit) as reflected in the consolidated statements of operations are as follows:
	Years ended December 31	2014				2013				2012

	Gross deferred tax assets were $3.6 billion and $3.7 billion at December 31, 2014 and 2013, respectively. Deferred tax assets, net of valuation allowances, were $3.4 billion and $3.5 billion at December 31, 2014 and 2013, respectively. Gross deferred tax liabilities were $774 million and $1.1 billion at December 31, 2014 and 2013, respectively.

	At December 31, 2014 and 2013, the Company had valuation allowances of $226 million and $200 million, respectively, against its deferred tax assets, including $195 million and $178 million, respectively, relating to deferred tax assets for non-U.S. subsidiaries. The Company’s valuation allowances for its non-U.S. subsidiaries had a net increase of $17 million during 2014 and a net decrease of $56 million during 2013. The increase in the valuation allowance relating to deferred tax assets of non-U.S. subsidiaries during 2014 relates to deferred tax assets that are not more-likely-than-not to be realizable based on estimates of future taxable income. The decrease in the valuation allowance relating to deferred tax assets of non-U.S. subsidiaries during 2013 reflects current year deferred tax movements, expiration of loss carryforwards and exchange rate variances.
	The Company’s U.S. valuation allowance had a net increase of $9 million during 2014 and a net decrease of $4 million during 2013. The U.S. valuation allowance of $31 million as of December 31, 2014 primarily relates to state tax carryforwards. The Company believes that the remaining deferred tax assets are more-likely-than-not to be realizable based on estimates of future taxable income and the implementation of tax planning strategies.
	Tax carryforwards are as follows:
	December 31, 2014	Gross			Tax				Expiration

Although the final resolution of the Company’s global tax disputes is uncertain, based on current information, in the opinion of the Company’s management, the ultimate disposition of these matters will not have a material adverse effect on the Company’s consolidated financial position, liquidity or results of operations. However, an unfavorable resolution of the Company’s global tax disputes could have a material adverse effect on the Company’s consolidated financial position, liquidity or results of operations in the periods in which the matters are ultimately resolved.
Based on the potential outcome of the Company’s global tax examinations, the expiration of the statute of limitations for specific jurisdictions, or the continued ability to satisfy tax incentive obligations, it is reasonably possible that the unrecognized tax benefits will change within the next twelve months. The associated net tax impact on the effective tax rate, exclusive of valuation allowance changes, is estimated to be in the range of a $50 million tax charge to a $50 million tax benefit, with cash payments not to exceed $25 million.
At December 31, 2014, the Company had $26 million accrued for interest and $26 million accrued for penalties on unrecognized tax benefits. At December 31, 2013, the Company had $25 million and $27 million accrued for interest and penalties, respectively, on unrecognized tax benefits.

Retirement Benefits	Retirement Benefits
	Pension and Postretirement Health Care Benefits Plans
	The Company’s noncontributory pension plan (the “Regular Pension Plan”) covered U.S. employees hired prior to January 1, 2005, who became eligible after one year of service. The benefit formula was dependent upon employee earnings and years of service. During 2014, the Company terminated this plan. The Company also provides defined benefit plans which cover non-U.S. employees in certain jurisdictions, principally the United Kingdom and Germany (the “Non U.S. Pension Benefit Plans”). Other pension plans outside of the U.S. are not material to the Company either individually or in the aggregate.
	The Company had a noncontributory supplemental retirement benefit plan (the “Officers’ Plan”) for its officers elected prior to December 31, 1999. The Officers’ Plan contained provisions for vesting and funding the participants’ expected retirement benefits when the participants met the minimum age and years of service requirements. Elected officers who were not yet vested in the Officers’ Plan as of December 31, 1999 had the option to remain in the Officers’ Plan or elect to have their benefit bought out in restricted stock units. Effective December 31, 1999, newly elected officers were not eligible to participate in the Officers’ Plan. Effective June 30, 2005, salaries were frozen for this plan. During 2013, the Company settled and terminated the Officers' Plan.
	The Company has an additional noncontributory supplemental retirement benefit plan, the Motorola Supplemental Pension Plan (“MSPP”), which provides supplemental benefits to individuals by replacing the Regular Pension Plan benefits that are lost by such individuals under the retirement formula due to application of the limitations imposed by the Internal Revenue Code. However, elected officers who were covered under the Officers’ Plan were not eligible to participate in the MSPP. Effective January 1, 2007, eligible compensation was capped at the IRS limit plus $175,000 (the “Cap”) or, for those already in excess of the Cap as of January 1, 2007, the eligible compensation used to compute such employee’s MSPP benefit for all future years is the greater of: (i) such employee’s eligible compensation as of January 1, 2007 (frozen at that amount) or (ii) the relevant Cap for the given year. Effective January 1, 2009, the MSPP was closed to new participants unless such participation was required under a prior contractual entitlement.
	In February 2007, the Company amended the Regular Pension Plan and the MSPP, modifying the definition of average earnings. For the years ended prior to December 31, 2007, benefits were calculated using the rolling average of the highest annual earnings in any five years within the previous ten calendar year period. Beginning in January 2008, the benefit calculation was based on the set of the five highest years of earnings within the ten calendar years prior to December 31, 2007, averaged with earnings from each year after 2007. In addition, effective January 2008, the Company amended the Regular Pension Plan, modifying the vesting period from five years to three years.
	In December 2008, the Company amended the Regular Pension Plan, the Officers’ Plan and the MSPP (collectively, the “U.S. Pension Benefit Plans”) such that, effective March 1, 2009: (i) no participant shall accrue any benefit or additional benefit on or after March 1, 2009, and (ii) no compensation increases earned by a participant on or after March 1, 2009 shall be used to compute any accrued benefit.
	Certain health care benefits are available to eligible domestic employees meeting certain age and service requirements upon termination of employment (the “Postretirement Health Care Benefits Plan”). For eligible employees hired prior to January 1, 2002, the Company offsets a portion of the postretirement medical costs to the retired participant. As of January 1, 2005, the Postretirement Health Care Benefits Plan was closed to new participants. During 2012, the Postretirement Health Care Benefits Plan was amended ("the Original Amendment"). As of January 1, 2013, benefits under the Postretirement Health Care Benefits Plan, are paid to a retiree health reimbursement account instead of directly providing health insurance coverage to certain participants.  Covered retirees are now able to use the annual subsidy they receive through this account toward the purchase of their own health care coverage from private insurance companies and for reimbursement of eligible health care expenses. The Original Amendment to the Postretirement Health Care Benefits Plan effective January 1, 2013 resulted in a remeasurement of the plan generating an $87 million decrease in accumulated other comprehensive loss, net of taxes. The majority of that $87 million decrease will be recognized by the end of 2015.
	In September 2014, the Postretirement Health Care Benefits Plan was amended (“the New Amendment”). As a result of the New Amendment, beginning March 1, 2015, all eligible retirees under the age of 65, will be able to use the annual subsidy they receive through their retiree health reimbursement account toward the purchase of their own health care coverage from private insurance companies and for the reimbursement of eligible health care expenses. Additionally, the New Amendment eliminated dental benefits under the plan. The New Amendment required a remeasurement of the plan, resulting in a $45 million decrease in Accumulated other comprehensive loss, net of taxes. A substantial portion of the decrease is related to a prior service credit and will be recognized as a credit to the consolidated statements of operations over almost three years, or the period in which the remaining employees eligible for the plan will qualify for benefits under the plan.
	During the years ended December 31, 2014, 2013, and 2012, $50 million, $43 million, and $16 million of prior service cost credit, respectively, was recognized into the Company’s consolidated statements of operations for amendments to the Postretirement Health Care Benefits Plan.
	In September 2014, the Company entered into a Definitive Purchase Agreement (the “Agreement”) by and among the Company, The Prudential Insurance Company of America (“PICA”), Prudential Financial, Inc. and State Street Bank and Trust Company, as Independent Fiduciary of the Company’s Regular Pension Plan. Under the Agreement, the Regular Pension Plan planned to purchase from PICA a group annuity contract that requires PICA to pay and administer certain future annuity payments to approximately 30,000 of the Company’s retirees. In anticipation of the Agreement, the Company established a new pension plan with substantially the same terms as the Regular Pension Plan (the “New Plan”) to accommodate the Company's remaining active employees and non-retirees. The establishment of the New Plan resulted in a mid-year remeasurement. On December 3, 2014, the Regular Pension Plan closed its planned purchase of a group annuity from PICA. The total premium paid by the Regular Pension Plan to PICA was the transfer of approximately $3.2 billion in plan assets, and is subject to customary post-closing true-ups. The Regular Pension Plan was then terminated.
	Also in September 2014, the Company announced that the New Plan was offering a maximum of $1.0 billion of lump-sum distributions to certain participants who had accrued a pension benefit, had left the Company prior to June 30, 2014, and had not yet started receiving pension benefit payments (the “Eligible Participants”). The aggregate amount of lump-sum elections accepted by Eligible Participants exceeded the maximum of $1.0 billion, and $1.0 billion was paid out from plan assets in December 2014.
	As a result of the actions taken to the Plans, the Company recorded a settlement loss of $1.9 billion in 2014 which is recorded in "Other charges" within the statement of operations.

	The benefit obligation and plan assets for the Company's plans are measured as of December 31, 2014. The Company utilizes a five-year, market-related asset value method of recognizing asset related gains and losses.
	Prior to 2013, unrecognized gains and losses were amortized over periods ranging from three to thirteen years. At the close of fiscal 2012, the Company determined that the majority of the Company's plan participants in its Regular Pension Plan and United Kingdom pension plan were no longer actively employed by the Company due to significant employee exits as a result of the Company's divestitures. Under relevant accounting rules, when almost all of the plan participants are considered inactive, the amortization period for certain unrecognized losses changes from the average remaining service period to the average remaining lifetime of the participants. As such, depending on the specific plan, the Company amortizes gains and losses over periods ranging from four to thirty-six years. Prior service costs are amortized over periods ranging from six to twelve years. Benefits under all pension plans are valued based on the projected unit credit cost method.
	The net periodic cost for 2015 will include amortization of the unrecognized net loss and prior service costs for the U.S. Pension Benefit Plans and Non U.S. Pension Benefit Plans, currently included in Accumulated other comprehensive loss, of $47 million and $11 million, respectively.  It is estimated that the 2015 net periodic expense for the Postretirement Health Care Benefits Plan will include amortization of a net credit of $49 million, comprised of the unrecognized prior service gain and unrecognized actuarial loss, currently included in Accumulated other comprehensive loss.
	Actuarial Assumptions
	Certain actuarial assumptions such as the discount rate and the long-term rate of return on plan assets have a significant effect on the amounts reported for net periodic cost and benefit obligation. The assumed discount rates reflect the prevailing market rates of a universe of high-quality, non-callable, corporate bonds currently available that, if the obligation were settled at the measurement date, would provide the necessary future cash flows to pay the benefit obligation when due. The long-term rates of return on plan assets represent an estimate of long-term returns on an investment portfolio consisting of a mixture of equities, fixed income, cash and other investments similar to the actual investment mix. In determining the long-term return on plan assets, the Company considers long-term rates of return on the asset classes (both historical and forecasted) in which the Company expects the plan funds to be invested.
	Weighted average actuarial assumptions used to determine costs for the plans at the beginning of the fiscal year were as follows:
	U.S. Pension Benefit Plans						Non U.S. Pension Benefit Plans					Postretirement Health Care Benefits Plan
	2014			2013			2014			2013		2014			2013
Discount rate	5.15	%		4.35	%		4.24	%		4.2	%	4.65	%		3.8	%
Investment return assumption	7	%		7	%		5.92	%		6.13	%	7	%		7	%
Weighted average actuarial assumptions used to determine benefit obligations for the plans were as follows:
	U.S. Pension Benefit Plans						Non U.S. Pension Benefit Plans					Postretirement Health Care Benefits Plan
	2014			2013			2014			2013		2014			2013
Discount rate	4.3	%		5.15	%		3.19	%		4.24	%	3.9	%		4.65	%
Future compensation increase rate	n/a			n/a			2.54	%		2.58	%	n/a			n/a
The accumulated benefit obligations for the plans were as follows:
	U.S. Pension Benefit Plans								Non U.S. Pension Benefit Plans
31-Dec	2014				2013				2014			2013
Accumulated benefit obligation	$	4,536			$	7,317			$	2,059		$	1,900
In September 2014, as a result of establishing the New Plan, the Company remeasured the Regular Pension Plan using a weighted average discount rate and expected long-term rate of return on assets of 4.25%. The Regular Pension Plan was subsequently terminated. The New Plan, which is the surviving plan, was measured using a discount rate and expected long-term rate of return on assets of 4.70% and 7.00%, respectively.
In September 2014, as a result of retiree healthcare design plan changes, the company remeasured the retiree healthcare plan using a weighted average discount rate and expected long-term rates of return on assets of 4.15% and 7.00%, respectively.
During 2014, the Company adopted the "RP 2014 White Collar" mortality table for purposes of calculating the projected benefit obligation for the Company's New Plan.
The health care cost trend rate used to determine the December 31, 2014 accumulated postretirement benefit obligation and 2015 net periodic benefit for the Postretirement Health Care Benefits Plan was 7.75%, grading down to a rate of 5.00% in 2021. The health care cost trend rate used to determine the December 31, 2013 accumulated postretirement benefit obligation and 2014 net periodic benefit was 8.50%, remaining flat at 8.50% through 2015, then grading down to a rate of 5.00% in 2020.
The effect of changing the health care trend rate by one percentage point on the accumulated postretirement benefit obligation and the net periodic cost of the Postretirement Health Care Benefits Plan is de minimis. The Company maintains a lifetime cap on postretirement health care costs, which reduces the liability duration of the plan. A result of this lower duration, is a decreased sensitivity to a change in the discount rate trend and health care cost assumptions with respect to the liability and related expense.
Investment Policy
The individual plans have adopted an investment policy designed to meet or exceed the expected rate of return on plan assets assumption. To achieve this, the plans retain professional advisors and investment managers that invest plan assets into various classes including, but are not limited to, equity, fixed income securities, cash, cash equivalents, commodities, hedge funds, infrastructure/utilities, insurance contracts, leveraged loan funds and real estate. In addition, some plans invest in insurance contracts. The Company uses long-term historical actual return experience with consideration of the expected investment mix of the plans’ assets, as well as future estimates of long-term investment returns, to develop its expected rate of return assumption used in calculating the net periodic cost. The individual plans have target mixes for these asset classes for all plans, which are readjusted periodically when an asset class weighting deviates from the target mix, with the goal of achieving the required return at a reasonable risk level.
The weighted-average asset allocations by asset categories for all pension and the Postretirement Health Care Benefits plans were as follows:
	All Pension Benefit Plans						Postretirement Health Care Benefits Plan
31-Dec	2014			2013			2014			2013
Target Mix:
Equity securities	41	%		55	%		37	%		57	%
Fixed income securities	44	%		43	%		42	%		42	%
Cash and other investments	15	%		2	%		21	%		1	%
Actual Mix:
Equity securities	43	%		55	%		20	%		58	%
Fixed income securities	44	%		42	%		20	%		40	%
Cash and other investments	13	%		3	%		60	%		2	%
Within the equity securities asset class, the investment policy provides for investments in a broad range of publicly-traded securities including both domestic and foreign equities. Within the fixed income securities asset class, the investment policy provides for investments in a broad range of publicly-traded debt securities including U.S. Treasury issues, corporate debt securities, mortgage and asset-backed securities, as well as foreign debt securities. In the cash and other investments asset class, investments may include, but are not limited to, cash, cash equivalents, commodities, hedge funds, infrastructure/utilities, insurance contracts, leveraged loan funds and real estate.
Cash Funding
The Company contributed $1.1 billion to its U.S. Pension Benefit Plans during 2014, compared to $150 million contributed in 2013. The Company contributed $237 million to its Non U.S. Pension Benefit Plans during 2014, compared to $32 million contributed in 2013. The Company expects to make no cash contributions to its U.S. Pension Benefit Plans and approximately $12 million to its Non U.S. Pension Benefit Plans in 2015. The Company does not expect to make cash contributions to the Postretirement Health Care Benefits Plan in 2015.
Expected Future Benefit Payments
The following benefit payments are expected to be paid:
Year	U.S. Pension Benefit Plans				Non U.S. Pension Benefit Plans				Postretirement Health Care Benefits Plan
2015	$	95			$	42			$	20
2016	93				43				19
2017	108				44				18

2020-2024	1,030				245				67
Other Benefit Plans
Split-Dollar Life Insurance Arrangements
The Company maintains a number of endorsement split-dollar life insurance policies on now-retired officers under a plan that was frozen prior to December 31, 2004. The Company had purchased the life insurance policies to insure the lives of employees and then entered into a separate agreement with the employees that split the policy benefits between the Company and the employee. Motorola Solutions owns the policies, controls all rights of ownership, and may terminate the insurance policies. To effect the split-dollar arrangement, Motorola Solutions endorsed a portion of the death benefits to the employee and upon the death of the employee, the employee’s beneficiary typically receives the designated portion of the death benefits directly from the insurance company and the Company receives the remainder of the death benefits. It is currently expected that minimal cash payments will be required to fund these policies.
The net periodic pension cost for these split-dollar life insurance arrangements was $5 million for the years ended December 31, 2014, 2013 and 2012. The Company has recorded a liability representing the actuarial present value of the future death benefits as of the employees’ expected retirement date of $66 million and $51 million as of December 31, 2014 and December 31, 2013, respectively.
Deferred Compensation Plan
The Company amended and reinstated its deferred compensation plan (“the Plan”) effective June 1, 2013 to reopen the Plan to certain participants. Under the Plan, participants may elect to defer base salary and cash incentive compensation in excess of 401(k) plan limitations.  Participants under the Plan may choose to invest their deferred amounts in the same investment alternatives available under the Company's 401(k) plan. The Plan also allows for Company matching contributions for the following: (i) the first 4% of compensation deferred under the Plan, subject to a maximum of $50,000 for board officers, (ii) lost matching amounts that would have been made under the 401(k) plan if participants had not participated in the Plan, and (iii) discretionary amounts as approved by the Compensation and Leadership Committee of the Board of Directors.
Defined Contribution Plan
The Company and certain subsidiaries have various defined contribution plans, in which all eligible employees may participate. In the U.S., the 401(k) plan is a contributory plan. Matching contributions are based upon the amount of the employees’ contributions. The Company’s expenses for material defined contribution plans for the years ended December 31, 2014, 2013 and 2012 were $31 million, $32 million and $30 million, respectively.
Beginning January 1, 2012, the Company may make an additional discretionary 401(k) plan matching contribution to eligible employees. For the years ended December 31, 2014, 2013, and 2012 the Company made no discretionary matching contributions.

	Stock Options, Stock Appreciation Rights and Employee Stock Purchase Plan
	The Company grants options to acquire shares of common stock to certain employees and to existing option holders of acquired companies in connection with the merging of option plans following an acquisition. Each option granted and stock appreciation right has an exercise price of no less than 100% of the fair market value of the common stock on the date of the grant. The awards have a contractual life of five to fifteen years and vest over two to four years. Stock options and stock appreciation rights assumed or replaced with comparable stock options or stock appreciation rights in conjunction with a change in control of the Company only become exercisable if the holder is also involuntarily terminated (for a reason other than cause) or quits for good reason within 24 months of a change in control.
	The employee stock purchase plan allows eligible participants to purchase shares of the Company’s common stock through payroll deductions of up to 20% of eligible compensation on an after-tax basis. Plan participants cannot purchase more than $25,000 of stock in any calendar year. The price an employee pays per share is 85% of the lower of the fair market value of the Company’s stock on the close of the first trading day or last trading day of the purchase period. The plan has two purchase periods, the first from October 1 through March 31 and the second from April 1 through September 30. For the years ended December 31, 2014, 2013 and 2012, employees purchased 1.4 million, 1.5 million and 1.4 million shares, respectively, at purchase prices of $51.76 and $53.79, $43.02 and $50.47, and $34.52 and $42.96, respectively.
	The Company calculates the value of each employee stock option, estimated on the date of grant, using the Black-Scholes option pricing model. The weighted-average estimated fair value of employee stock options granted during 2014, 2013 and 2012 was $11.02, $9.52 and $9.60, respectively, using the following weighted-average assumptions:
		2014			2013			2012
	Expected volatility	21.7	%		22.1	%		24	%
	Risk-free interest rate	1.6	%		0.9	%		0.8	%
	Dividend yield	2.5	%		2.4	%		2.2	%
	Expected life (years)	5.2			5.9			6.1
	The Company uses the implied volatility for traded options on the Company’s stock as the expected volatility assumption required in the Black-Scholes model. The selection of the implied volatility approach was based upon the availability of actively traded options on the Company’s stock and the Company’s assessment that implied volatility is more representative of future stock price trends than historical volatility.
	The risk-free interest rate assumption is based upon the average daily closing rates during the year for U.S. Treasury notes that have a life which approximates the expected life of the option. The dividend yield assumption is based on the Company’s future expectation of dividend payouts. The expected life of employee stock options represents the average of the contractual term of the options and the weighted-average vesting period for all option tranches.
	The Company has applied forfeiture rates, estimated based on historical data, of 10%-50% to the option fair values calculated by the Black-Scholes option pricing model. These estimated forfeiture rates are applied to grants based on their remaining vesting term and may be revised in subsequent periods if actual forfeitures differ from these estimates.

Cash received from stock option exercises and the employee stock purchase plan was $135 million, $165 million and $133 million for the years ended December 31, 2014, 2013 and 2012, respectively. The total intrinsic value of options exercised during the years ended December 31, 2014, 2013 and 2012 was $38 million, $85 million and $59 million, respectively. The aggregate intrinsic value for options outstanding and exercisable as of December 31, 2014 was $119 million and $103 million, respectively, based on a December 31, 2014 stock price of $67.08 per share.

	Restricted Stock and Restricted Stock Units
	Restricted stock (“RS”) and restricted stock unit (“RSU”) grants consist of shares or the rights to shares of the Company’s common stock which are awarded to employees and non-employee directors. The grants are restricted such that they are subject to substantial risk of forfeiture and to restrictions on their sale or other transfer by the employee. Shares of RS and RSUs assumed or replaced with comparable shares of RS or RSUs in conjunction with a change in control will only have the restrictions lapse if the holder is also involuntarily terminated (for a reason other than cause) or quits for good reason within 24 months of a change in control.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements
	The Company holds certain fixed income securities, equity securities and derivatives, which are recognized and disclosed at fair value in the financial statements on a recurring basis. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. Fair value is measured using the fair value hierarchy and related valuation methodologies as defined in the authoritative literature. This guidance specifies a hierarchy of valuation techniques based on whether the inputs to each measurement are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company's assumptions about current market conditions. The prescribed fair value hierarchy and related valuation methodologies as they pertain to the Company are as follows:
	Level 1 - Quoted market prices in active markets are available for investments in common and preferred stock and common stock equivalents.
	Level 2 - The securities classified as Level 2 are comprised primarily of corporate, government, agency, and government sponsored enterprise fixed income securities. Our pension plan assets also include commingled equities classified as Level 2. These securities are priced using pricing services, bid/offer, and last trade. Prices may also be obtained from brokers, counterparties, fund administrators, online securities data services, or investment managers. Fixed income securities and commingled equities, including short-term instruments, may be priced using pricing models comprised of observable inputs which include, but are not limited to, market quotations, yields, maturities, call features, and the security's terms and conditions.
	In determining the fair value of the Company's foreign currency derivatives, the Company uses forward contract and option valuation models employing market observable inputs, such as spot currency rates, time value and option volatilities. Since the Company primarily uses observable inputs in its valuation of its derivative assets and liabilities, they are classified as Level 2 assets.
	Level 3 - The securities classified as Level 3 primarily consist of corporate bonds held in one of our non-U.S. pension plans. These corporate bonds are valued using pricing models which contain unobservable inputs and have limited liquidity. Determining the fair value of these securities requires the use of unobservable inputs, such as indicative quotes from dealers, extrapolated data, proprietary models and qualitative input from investment advisors.

At December 31, 2014, the Company had $3.3 billion of investments in money market funds (Level 2) classified as Cash and cash equivalents in its consolidated balance sheet, compared to $2.1 billion at December 31, 2013. The money market funds had quoted market prices that are equivalent to par.
Using quoted market prices and market interest rates, the Company determined that the fair value of long-term debt at December 31, 2014 was $3.6 billion (Level 2), compared to a face value of $3.5 billion. Since considerable judgment is required in interpreting market information, the fair value of the long-term debt is not necessarily indicative of the amount which could be realized in a current market exchange.
All other financial instruments are carried at cost, which is not materially different from the instruments’ fair values.

Receivables [Abstract]
Long-term Customer Financing and Sales Of Receivables	Long-term Customer Financing and Sales of Receivables
	Long-term Customer Financing
	Long-term receivables consist of trade receivables with payment terms greater than twelve months, long-term loans and lease receivables under sales-type leases. Long-term receivables consist of the following:
	31-Dec	2014			2013
	Long-term receivables	$	49		$	27
	Less current portion	(18		)	(26		)
	Non-current long-term receivables, net	$	31		$	1
	The current portion of long-term receivables is included in Accounts receivable and the non-current portion of long-term receivables is included in Other assets in the Company’s consolidated balance sheets. There was $1 million Interest income recognized on long-term receivables for the year ended December 31, 2014. There was no interest income recognized on long-term receivables for the year ended 2013 and $5 million for the year ended 2012.
	Certain purchasers of the Company's products and services may request that the Company provide long-term financing (defined as financing with a term greater than one year) in connection with the sale of products and services. These requests may include all or a portion of the purchase price of the products and services. The Company's obligation to provide long-term financing may be conditioned on the issuance of a letter of credit in favor of the Company by a reputable bank to support the purchaser's credit or a pre-existing commitment from a reputable bank to purchase the long-term receivables from the Company. The Company had outstanding commitments to provide long-term financing to third-parties totaling $293 million at December 31, 2014, compared to $50 million at December 31, 2013.
	Sales of Receivables
	From time to time, the Company sells accounts receivable and long-term receivables to third-parties under one-time arrangements while others are sold to third-parties. The Company may or may not retain the obligation to service the sold accounts receivable and long-term receivables.
	The following table summarizes the proceeds received from sales of accounts receivable and long-term receivables for the years ended December 31, 2014, 2013 and 2012.
	Years ended December 31	2014			2013			2012
	Cumulative annual proceeds received from sales:
	Accounts receivable sales proceeds	$	50		$	14		$	12
	Long-term receivables sales proceeds	124			131			178
	Total proceeds from receivable sales	$	174		$	145		$	190
	At December 31, 2014, the Company had retained servicing obligations for $496 million of long-term receivables, compared to $434 million of long-term receivables at December 31, 2013. Servicing obligations are limited to collection activities of sold accounts receivables and long-term receivables.
	Credit Quality of Customer Financing Receivables and Allowance for Credit Losses
	An aging analysis of financing receivables at December 31, 2014 and December 31, 2013 is as follows:
	December 31, 2014	Total			Past Due Over 90 Days
		Long-term
		Receivable
	Municipal leases secured tax exempt	$	14		$	—
	Commercial loans and leases secured	35			12
	Total gross long-term receivables, including current portion	$	49		$	12
	December 31, 2013	Total			Current Billed			Past Due Under 90 Days		Past Due Over 90 Days
		Long-term			Due
		Receivable
	Municipal leases secured tax exempt	$	1		$	—		$	—	$	—
	Commercial loans and leases secured	26			10			2		10
	Total gross long-term receivables, including current portion	$	27		$	10		$	2	$	10
	The Company uses an internally developed credit risk rating system for establishing customer credit limits. This system is aligned and comparable to the rating systems utilized by independent rating agencies.
	The Company’s policy for valuing the allowance for credit losses is to review all customer financing receivables for collectability on an individual receivable basis. For those receivables where collection risk is probable, the Company calculates the value of impairment based on the net present value of expected future cash flows from the customer.
	The Company had a total of $12 million of financing receivables past due over 90 days as of December 31, 2014 in relation to two loans. The Company is not accruing interest on these loans as of December 31, 2014, which are adequately reserved.

	Lease Obligations
	The Company leases certain office, factory and warehouse space, land, and information technology and other equipment under principally non-cancelable operating leases. Rental expense, net of sublease income, for the years ended December 31, 2014, 2013 and 2012 was $62 million, $51 million, and $45 million, respectively.
	At December 31, 2014, future minimum lease obligations, net of minimum sublease rentals, for the next five years and beyond are as follows:
	Year
	2015	$	68
	2016	56
	2017	45
	2018	35
	2019	33
	Beyond	217
	Purchase Obligations
	During the normal course of business, in order to manage manufacturing lead times and help ensure adequate component supply, the Company enters into agreements with contract manufacturers and suppliers that either allow them to procure inventory based upon criteria as defined by the Company or establish the parameters defining the Company’s requirements. In addition, we have entered into software license agreements which are firm commitments and are not cancelable. As of December 31, 2014, the Company had entered into firm, noncancelable, and unconditional commitments under such arrangements through 2017. The Company expects to make total payments of $40 million under these arrangements as follows: $23 million in 2015, $14 million in 2016, and $3 million in 2017.
	The Company outsources certain corporate functions, such as benefit administration and information technology related services, the longest of which is expected to expire in 2019. The remaining payments under these contracts are approximately $319 million over the remaining life of the contracts; however, these contracts can be terminated. Termination would result in a penalty substantially less than the remaining annual contract payments. The Company would also be required to find another source for these services, including the possibility of performing them in-house.
	Legal
	The Company is a defendant in various lawsuits, claims and actions that arise in the normal course of business. While the outcome of these matters is currently not determinable, the Company does not expect the ultimate disposition of these matters to have a material adverse effect on the Company’s consolidated financial position, liquidity or results of operations.
	Indemnifications
	The Company is a party to a variety of agreements pursuant to which it is obligated to indemnify the other party with respect to certain matters. In indemnification cases, payment by the Company is conditioned on the other party making a claim pursuant to the procedures specified in the particular contract, which procedures typically allow the Company to challenge the other party's claims. In some instances, the Company may have recourse against third-parties for certain payments made by the Company.
	Some of these obligations arise as a result of divestitures of the Company's assets or businesses and require the Company to indemnify the other party against losses arising from breaches of representations and warranties and covenants and, in some cases, the settlement of pending obligations. The Company's obligations under divestiture agreements for indemnification based on breaches of representations and warranties are generally limited in terms of duration, and for amounts for breaches of such representations and warranties in connection with prior divestitures not in excess of a percentage of the contract value. The Company had no pending claims at December 31, 2014.
	In addition, the Company may provide indemnifications for losses that result from the breach of general warranties contained in certain commercial and intellectual property agreements. Historically, the Company has not made significant payments under these agreements.

Restructuring and Related Activities [Abstract]
Reorganization of Businesses	Reorganization of Businesses
	The Company maintains a formal Involuntary Severance Plan (the “Severance Plan”), which permits the Company to offer eligible employees severance benefits based on years of service and employment grade level in the event that employment is involuntarily terminated as a result of a reduction-in-force or restructuring. The Severance Plan includes defined formulas to calculate employees’ termination benefits.  In addition to the Involuntary Severance Plan, during the year ended December 31, 2013, the Company accepted voluntary applications to its Severance Plan from a defined subset of employees within the United States.  Voluntary applicants received termination benefits based on the formulas defined in the Severance Plan; however, termination benefits, which are normally capped at six months of salary, were capped at a full year’s salary.
	The Company recognizes termination benefits based on formulas per the Severance Plan at the point in time that future settlement is probable and can be reasonably estimated based on estimates prepared at the time a restructuring plan is approved by management. Exit costs consist of future minimum lease payments on vacated facilities and other contractual terminations. At each reporting date, the Company evaluates its accruals for employee separation and exit costs to ensure the accruals are still appropriate. In certain circumstances, accruals are no longer needed because of efficiencies in carrying out the plans or because employees previously identified for separation resigned from the Company and did not receive severance, or were redeployed due to circumstances not foreseen when the original plans were approved. In these cases, the Company reverses accruals through the consolidated statements of operations where the original charges were recorded when it is determined they are no longer needed.
	During 2014, 2013, and 2012 the Company continued to implement various productivity improvement plans aimed at achieving long-term, sustainable profitability by driving efficiencies and reducing operating costs. Both of the Company’s segments were impacted by these plans. The employees affected were located in all geographic regions.
	2014 Charges
	During 2014, the Company recorded net reorganization of business charges of $73 million, including $9 million of charges in Costs of sales and $64 million of charges in Other charges in the Company’s consolidated statements of operations. Included in the aggregate $73 million are charges of $67 million for employee separation costs and, $7 million for exit costs, partially offset by $1 million of reversals for accruals no longer needed.

	At January 1, 2014, the Company had an accrual of $6 million for exit costs attributable to lease terminations. There were $7 million of additional charges in 2014. The $13 million used in 2014 reflects cash payments. There is no remaining accrual as of December 31, 2014.
	Employee Separation Costs

The 2014 additional charges of $93 million represent severance costs for approximately an additional 1,200 employees, of which 300 were direct employees and 900 were indirect employees. The adjustments of $4 million reflect reversals of accruals no longer needed. The $135 million used in 2014 reflects cash payments to separated employees, including $50 million related to employees of the Enterprise business and included in cash flow from discontinued operations. The remaining accrual of $57 million, which is included in Accrued liabilities in the Company’s consolidated balance sheet at December 31, 2014, is expected to be paid, generally, within one year to: (i) severed employees who have already begun to receive payments and (ii) approximately 500 employees to be separated in 2015.
	2013 Charges
	During 2013, the Company recorded net reorganization of business charges of $86 million, including $16 million of charges in Costs of sales and $70 million of charges under Other charges in the Company’s consolidated statements of operations. Included in the aggregate $86 million are charges of (i) $94 million for employee separation costs, and (ii) $2 million of charges for exit costs, partially offset by $10 million of reversals for accruals no longer needed.

	Exit Costs
	At January 1, 2012, the Company had an accrual of $14 million for exit costs attributable to lease terminations. The adjustment of $1 million reflects an adjustment for additional accruals needed. The $11 million used in 2012 reflects cash payments. The remaining accrual of $4 million, which was included in Accrued liabilities in the Company’s consolidated balance sheets at December 31, 2012, represented future cash payments, primarily for lease termination obligations.
	Employee Separation Costs
	At January 1, 2012, the Company had an accrual of $30 million for employee separation costs, representing the severance costs for approximately 700 employees. The additional 2012 charges of $54 million were severance costs for approximately an additional 1,000 employees, of which 300 were direct employees and 700 were indirect employees. The adjustments of $9 million reflect accruals no longer required. The $44 million used in 2012 reflects cash payments to these separated employees, including $20 million related to employees of the Enterprise business and included in cash flow from discontinued operations. The remaining accrual of $31 million was included in Accrued liabilities in the Company’s consolidated balance sheet at December 31, 2012.

	On December 31, 2013, the Company completed the acquisition of a communication software provider in push-to-talk-over-broadband applications for a gross purchase price of $48 million. As a result of the acquisition, the Company recognized $22 million of goodwill and $20 million of identifiable intangible assets.
	On November 18, 2014, the Company completed the acquisition of an equipment provider for a gross purchase price of $22 million with $3 million of net tangible assets. The Company will complete the purchase price allocation for this acquisition during the first quarter of 2015, pending completion.  As of December 31, 2014, $19 million is included in Other assets in the Company’s consolidated balance sheet.
	The Company conducts its annual assessment of goodwill for impairment in the fourth quarter of each year. The goodwill impairment assessment is performed at the reporting unit level. A reporting unit is an operating segment or one level below an operating segment. The Company has determined that the Products segment and Services segment each meet the definition of a reporting unit.
	The Company performed a qualitative assessment to determine whether it was more-likely-than-not that the fair value of each reporting unit was less than its carrying amount for the fiscal years 2014, 2013, and 2012. In performing this qualitative assessment the Company assessed relevant events and circumstances including macroeconomic conditions, industry and market conditions, cost factors, overall financial performance, changes in share price, and entity-specific events. For fiscal years 2014, 2013, and 2012, the Company concluded it was more-likely-than-not that the fair value of each reporting unit exceeded its carrying value. Therefore, the two-step goodwill impairment test was not required and there was no impairment of goodwill.

Summary_Of_Significant_Account1

Summary Of Significant Accounting Policies (Policy)	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Principles Of Consolidation	Principles of Consolidation:    The consolidated financial statements include the accounts of Motorola Solutions, Inc. (the “Company” or “Motorola Solutions”) and all controlled subsidiaries. All intercompany transactions and balances have been eliminated.
	The consolidated financial statements as of December 31, 2014 and 2013 and for the years ended December 31, 2014, 2013 and 2012, include, in the opinion of management, all adjustments (consisting of normal recurring adjustments and reclassifications) necessary to present fairly the Company's consolidated financial position, results of operations, statements of comprehensive income, statement of stockholder's equity, and cash flows for all periods presented.
Use of Estimates	Use of Estimates: The preparation of financial statements in conformity with United States ("U.S.") Generally Accepted Accounting Principles ("GAAP") requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates
Revenue Recognition
	Revenue Recognition: Net sales consist of a wide range of activities including the delivery of stand-alone equipment or services, custom design and installation over a period of time, and bundled sales of equipment, software and services. The Company enters into revenue arrangements that may consist of multiple deliverables of its products and services due to the needs of its customers. The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable, and collectability of the sales price is reasonably assured. The Company recognizes revenue from the sale of equipment, equipment containing both software and nonsoftware components that function together to deliver the equipment’s essential functionality, and services in accordance with general revenue recognition accounting principles. The Company recognizes revenue in accordance with software accounting guidance for the following types of sales transactions: (i) standalone sales of software products or software upgrades, (ii) standalone sales of software maintenance agreements, and (iii) sales of software bundled with equipment where the software is not essential to the functionality of that equipment.
	Products
	For equipment sales, in addition to the criteria mentioned above, revenue recognition occurs when title and risk of loss has transferred to the customer, objective evidence exists that customer acceptance provisions have been met, no significant obligations remain and allowances for discounts, price protection, returns and customer incentives can be reliably estimated. Recorded revenues are reduced by these allowances. The Company bases its estimates of these allowances on historical experience taking into consideration the type of products sold, the type of customer, and the specific type of transaction in each arrangement. Where customer incentives cannot be reliably estimated, the Company defers revenue until the incentive has been finalized with the customer. The Company includes shipping charges billed to customers in net revenue, and includes the related shipping costs in cost of sales.
	The Company sells software and equipment obtained from other companies. The Company establishes its own pricing and retains related inventory risk, is the primary obligor in sales transactions with customers, and assumes the credit risk for amounts billed to customers. Accordingly, the Company generally recognizes revenue for the sale of products obtained from other companies based on the gross amount billed.
	Long-Term Contracts
	For long-term contracts that involve customization of equipment and/or software, the Company generally recognizes revenue using the percentage of completion method based on the percentage of costs incurred to date compared to the total estimated costs to complete the contract (“Estimated Costs at Completion”). The components of estimated costs to complete a contract and management’s process for reviewing Estimated Costs at Completion and progress toward completion is discussed further below. Contracts may be combined or segmented in accordance with the applicable criteria under contract accounting principles. In certain instances, when revenues or costs associated with long-term contracts cannot be reliably estimated or the contract contains other inherent uncertainties, revenues and costs are deferred until the project is complete and customer acceptance is obtained.
	Total Estimated Costs at Completion include direct labor, material and subcontracting costs. Due to the nature of the work required to be performed under many of the Company’s long-term contracts, determining Estimated Costs at Completion is complex and subject to many variables. The Company has a standard and disciplined quarterly Estimated Costs at Completion process in which management reviews the progress and performance of open contracts. As part of this process, management reviews information including, but not limited to, any outstanding key contract matters, progress towards completion, the project schedule, identified risks and opportunities, and the related changes in estimates of revenues and costs. The risks and opportunities include management's judgment about the ability and cost to achieve the project schedule, technical requirements, and other contract requirements. Management must make assumptions and estimates regarding labor productivity and availability, the complexity of the work to be performed, the availability of materials, and performance by subcontractors, among other variables. Based on this analysis, any quarterly adjustments to net sales, cost of sales, and the related impact to operating income are recorded as necessary in the period they become known. These adjustments may result from positive project performance, and may result in an increase in operating income during the performance of individual contracts. Likewise, these adjustments may result in a decrease in operating income if Estimated Costs at Completion increase. Changes in estimates of net sales or cost of sales could affect the profitability of one or more of our contracts. The impact on Operating earnings as a result of changes in Estimated Costs at Completion was not significant for the years 2014, 2013, and 2012. When estimates of total costs to be incurred on a contract exceed total estimates of revenue to be earned, a provision for the entire loss on the contract is recorded in the period the loss is determined.
	Hardware and Software Services Support
	Revenue under equipment and software maintenance agreements, which do not contain specified future software upgrades, is recognized ratably over the contract term as services are performed.
	Software and Licenses
	Revenue from pre-paid perpetual licenses is recognized at the inception of the arrangement, presuming all other relevant revenue recognition criteria are met. Revenue from non-perpetual licenses or term licenses is recognized ratably over the period that the licensee uses the license.
	Multiple-Element Arrangements
	Arrangements with customers may include multiple deliverables, including any combination of products, services and software. These multiple-element arrangements could also include an element accounted for as a long-term contract coupled with other products, services and software. For multiple-element arrangements that include products containing software that functions together with the equipment to deliver its essential functionality, undelivered software elements that relate to the product's essential software, and undelivered non-software services deliverables are separated into more than one unit of accounting when: (i) the delivered element(s) have value to the customer on a stand-alone basis and (ii) delivery of the undelivered element(s) is probable and substantially in the control of the Company.
	In these arrangements, the Company allocates revenue to all deliverables based on their relative selling prices. The Company uses the following hierarchy to determine the selling price to be used for allocating revenue to deliverables: (i) vendor-specific objective evidence of fair value (“VSOE”), (ii) third-party evidence of selling price (“TPE”), and (iii) best estimate of selling price (“ESP”).
	The Company determines VSOE based on its normal pricing and discounting practices for the specific product or service when that same product or service is sold separately. In determining VSOE, the Company requires that a substantial majority of the selling prices for a product or service fall within a reasonably narrow pricing range, generally evidenced by the pricing rates of approximately 80% of such historical stand-alone transactions falling within plus or minus 15% of the median rate.
	When VSOE does not exist, the Company attempts to determine TPE based on competitor prices for similar deliverables when sold separately. Generally, the Company's go-to-market strategy for many of its products differs from that of its competitors and its offerings contain a significant level of customization and differentiation such that the comparable pricing of products with similar functionality sold by other companies cannot be obtained. Furthermore, the Company is unable to reliably determine what similar competitor products’ selling prices are on a stand-alone basis. Therefore, the Company is typically not able to determine TPE.
	When both VSOE and TPE are unavailable, the Company uses ESP. The Company determines ESP by: (i) collecting all reasonably available data points including sales, cost and margin analysis of the product, and other inputs based on its normal pricing and discounting practices, (ii) making any reasonably required adjustments to the data based on market and Company-specific factors, and (iii) stratifying the data points, when appropriate, based on customer, magnitude of the transaction and sales volume.
	The Company also considers the geographies in which the products or services are sold, major product and service groups, customer classification, and other environmental or marketing variables in determining VSOE, TPE, and ESP.
	Once elements of an arrangement are separated into more than one unit of accounting, revenue is recognized for each separate unit of accounting based on the nature of the revenue as described above.
	The Company's arrangements with multiple deliverables may also contain one or more software deliverables that are subject to software revenue recognition guidance. The revenue for these multiple-element arrangements is allocated to the software deliverable(s) and the non-software deliverable(s) based on the relative selling prices of all of the deliverables in the arrangement using the fair value hierarchy outlined above. In circumstances where the Company cannot determine VSOE or TPE of the selling price for any of the deliverables in the arrangement, ESP is used for the purpose of allocating the arrangement consideration between software and non-software deliverables.
	The Company allocates arrangement consideration to multiple software or software-related deliverables, including the sale of software upgrades or software support agreements to previously sold software, in accordance with software accounting guidance. For such arrangements, revenue is allocated to the deliverables based on the relative fair value of each element, and fair value is determined using VSOE. Where VSOE does not exist for the undelivered software element, revenue is deferred until either the undelivered element is delivered or VSOE is established, whichever occurs first. When the final undelivered software element is post contract support, service revenue is recognized on a ratable basis over the remaining service period. When VSOE of a delivered element has not been established, but VSOE exists for the undelivered elements, the Company uses the residual method to recognize revenue when the fair value of all undelivered elements is determinable. Under the residual method, the fair value of the undelivered elements is deferred and the remaining portion of the arrangement consideration is allocated to the delivered elements and is recognized as revenue.
Cash Equivalents	Cash Equivalents:    The Company considers all highly-liquid investments purchased with an original maturity of three months or less to be cash equivalents.
Sigma Fund	Sigma Fund:    Prior to December 2013, the Company invested most of its U.S. dollar-denominated cash in a fund (the “Sigma Fund”) which was managed by independent investment management firms under specific investment guidelines restricting the type of investments held and their time to maturity. In December 2013, the Company completed the liquidation of the Sigma Fund and migrated the international U.S. dollar denominated cash to a U.S. dollar cash pool invested primarily in U.S. dollar prime money market funds.
Investments	Investments:    Investments in equity and debt securities classified as available-for-sale are carried at fair value. When applicable, debt securities classified as held-to-maturity are carried at amortized cost. Equity securities that are restricted for more than one year or that are not publicly traded are carried at cost. Certain investments are accounted for using the equity method if the Company has significant influence over the issuing entity.
	The Company assesses declines in the fair value of investments to determine whether such declines are other-than-temporary. This assessment is made considering all available evidence, including changes in general market conditions, specific industry and individual company data, the length of time and the extent to which the fair value has been less than cost, the financial condition and the near-term prospects of the entity issuing the security, and the Company’s ability and intent to hold the investment until recovery. Other-than-temporary impairments of investments are recorded to Other within Other income (expense) in the Company’s consolidated statements of operations in the period in which they become impaired.
Inventories	Inventories:    Inventories are valued at the lower of average cost (which approximates cost on a first-in, first-out basis) or market (net realizable value or replacement cost).
Property, Plant, And Equipment	Property, Plant and Equipment:    Property, plant and equipment are stated at cost less accumulated depreciation. Depreciation is recorded on a straight-line basis, based on the estimated useful lives of the assets (buildings and building equipment, five to forty years; machinery and equipment, two to ten years) and commences once the assets are ready for their intended use.
Goodwill And Intangible Assets	Goodwill and Intangible Assets:    Goodwill is assessed for impairment at least annually at the reporting unit level. The Company performs its annual assessment of goodwill for impairment in the fourth quarter of each fiscal year. The annual assessment is performed using the two-step goodwill test which may also include the optional qualitative assessment to determine whether it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount prior to performing the two-step goodwill impairment test. If this is the case, the two-step goodwill impairment test is required. If it is more-likely-than-not that the fair value of a reporting unit is greater than its carrying amount, the two-step goodwill impairment test is not required.
	If the two-step goodwill impairment test is performed, first, the fair value of each reporting unit is compared to its book value. If the fair value of the reporting unit is less than its book value, the Company performs a hypothetical purchase price allocation based on the reporting unit's fair value to determine the fair value of the reporting unit's goodwill. Fair value is determined using a combination of present value techniques and market prices of comparable businesses.
	Intangible assets are amortized on a straight line basis over their respective estimated useful lives ranging from one to ten years. The Company has no intangible assets with indefinite useful lives.
Impairment Of Long-Lived Assets	Impairment of Long-Lived Assets: Long-lived assets, which include intangible assets, held and used by the Company, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of assets may not be recoverable. The Company evaluates recoverability of assets to be held and used by comparing the carrying amount of an asset (group) to future net undiscounted cash flows to be generated by the asset (group). If an asset (group) is considered to be impaired, the impairment to be recognized is equal to the amount by which the carrying amount of the asset (group) exceeds the asset's (group's) fair value calculated using a discounted future cash flows analysis or market comparables. Assets held for sale, if any, are reported at the lower of the carrying amount or fair value less cost to sell.
Income Taxes
	Income Taxes: Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities from a change in tax rates is recognized in the period that includes the enactment date.
	Deferred tax assets are reduced by valuation allowances if, based on the consideration of all available evidence, it is more-likely-than-not that all or some portion of the deferred tax asset will not be realized. Significant weight is given to evidence that can be objectively verified. The Company evaluates deferred tax assets on a quarterly basis to determine if valuation allowances are required by considering available evidence. Deferred tax assets are realized by having sufficient future taxable income to allow the related tax benefits to reduce taxes otherwise payable. The sources of taxable income that may be available to realize the benefit of deferred tax assets are future reversals of existing taxable temporary differences, future taxable income, exclusive of reversing temporary differences and carryforwards, taxable income in carry-back years and tax planning strategies that are both prudent and feasible.
	The Company recognizes the effect of income tax positions only if sustaining those positions is more-likely-than-not. Changes in recognition or measurement are reflected in the period in which a change in judgment occurs. The Company records interest related to unrecognized tax benefits in Interest expense and penalties in Selling, general and administrative expenses in the Company’s consolidated statements of operations.
Sales And Use Taxes
	Sales and Use Taxes: The Company records taxes imposed on revenue-producing transactions, including sales, use, value added and excise taxes, on a net basis with such taxes excluded from revenue.
Long-Term Receivables	Long-term Receivables:    Long-term receivables include trade receivables where contractual terms of the note agreement are greater than one year. Long-term receivables are considered impaired when management determines collection of all amounts due according to the contractual terms of the note agreement, including principal and interest, is no longer probable. Impaired long-term receivables are valued based on the present value of expected future cash flows discounted at the receivable’s effective interest rate, or the fair value of the collateral if the receivable is collateral dependent. Interest income and late fees on impaired long-term receivables are recognized only when payments are received. Previously impaired long-term receivables are no longer considered impaired and are reclassified to performing when they have performed under a workout or restructuring for four consecutive quarters.
Foreign Currency	Foreign Currency:    Certain of the Company’s non-U.S. operations use their respective local currency as their functional currency. Those operations that do not have the U.S. dollar as their functional currency translate assets and liabilities at current rates of exchange in effect at the balance sheet date and revenues and expenses using rates that approximate those in effect during the period. The resulting translation adjustments are included as a component of Accumulated other comprehensive loss in the Company’s consolidated balance sheets. For those operations that have the U.S. dollar as their functional currency, transactions denominated in the local currency are measured in U.S. dollars using the current rates of exchange for monetary assets and liabilities and historical rates of exchange for nonmonetary assets. Gains and losses from remeasurement of monetary assets and liabilities are included in Other within Other income (expense) within the Company’s consolidated statements of operations.
Derivative Instruments	Derivative Instruments:    Gains and losses on hedges of existing assets or liabilities are marked-to-market and the result is included in Other within Other income (expense) within the Company’s consolidated statements of operations. Certain financial instruments are used to hedge firm future commitments or forecasted transactions.  Gains and losses pertaining to those instruments that qualify for hedge accounting are deferred until such time as the underlying transactions are recognized and subsequently recognized in the same line within the consolidated statements of operations as the hedged item. Gains and losses pertaining to those instruments that do not qualify for hedge accounting are recorded immediately in Other income (expense) within the consolidated statements of operations.
Earnings Per Share	Earnings Per Share:    The Company calculates its basic earnings (loss) per share based on the weighted-average effect of all common shares issued and outstanding. Net earnings (loss) attributable to Motorola Solutions, Inc. is divided by the weighted average common shares outstanding during the period to arrive at the basic earnings (loss) per share. Diluted earnings (loss) per share is calculated by dividing net earnings (loss) attributable to Motorola Solutions, Inc. by the sum of the weighted average number of common shares used in the basic earnings (loss) per share calculation and the weighted average number of common shares that would be issued assuming exercise or conversion of all potentially dilutive securities, excluding those securities that would be anti-dilutive to the earnings (loss) per share calculation. Both basic and diluted earnings (loss) per share amounts are calculated for earnings (loss) from continuing operations and net earnings attributable to Motorola Solutions, Inc. for all periods presented.
Share-Based Compensation Costs	Share-Based Compensation Costs:    The Company has incentive plans that reward employees with stock options, stock appreciation rights, restricted stock and restricted stock units, as well as an employee stock purchase plan. The amount of compensation cost for these share-based awards is generally measured based on the fair value of the awards as of the date that the share-based awards are issued and adjusted to the estimated number of awards that are expected to vest. The fair values of stock options and stock appreciation rights are generally determined using a Black-Scholes option pricing model which incorporates assumptions about expected volatility, risk free rate, dividend yield, and expected life. Compensation cost for share-based awards is recognized on a straight-line basis over the vesting period.
Retirement Benefits	Retirement Benefits:    The Company records annual expenses relating to its pension benefit and postretirement plans based on calculations which include various actuarial assumptions, including discount rates, assumed asset rates of return, compensation increases, turnover rates and health care cost trend rates. The Company reviews its actuarial assumptions on an annual basis and makes modifications to the assumptions based on current rates and trends. The effects of the gains, losses, and prior service costs and credits are amortized either over the average service life or over the average remaining lifetime of the participants, depending on the number of active employees in the plan. The funded status, or projected benefit obligation less plan assets, for each plan, is reflected in the Company’s consolidated balance sheets using a December 31 measurement date.
Advertising Expense	Advertising Expense:    Advertising expenses, which are the external costs of marketing the Company’s products, are expensed as incurred.
Recent Accounting Pronouncements
	Recent Accounting Pronouncements: In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers." This new standard will replace most existing revenue recognition guidance in U.S. GAAP. The core principle of the ASU is that an entity should recognize revenue for the transfer of goods or services equal to the amount it expects to receive for those goods and services. The ASU requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and estimates, and changes in those estimates. The ASU will be effective for the Company beginning January 1, 2017, and allows for both retrospective and modified-retrospective methods of adoption. The Company is in the process of determining the method of adoption it will elect and is currently assessing the impact of this ASU on its consolidated financial statements and footnote disclosures.
