Nature of Operations	1	Nature of Operations
	The company was originally incorporated in California in 1997, and reincorporated in Delaware in 2014 and in March 2015 announced it will conduct business under the name pdvWireless. The company is engaged in the development and sale of wireless communications applications, including at times the sale and installation of equipment used to run these applications. The company’s applications are primarily marketed to the end users of the wireless communications carriers under licensing agreements with the company. The company also sells certain applications directly to end users. The company maintains offices in Woodland Park, New Jersey, Reston, Virginia and San Diego, California.
	On September 15, 2014, the company completed an acquisition from Sprint Corporation pursuant to the Sprint APA (as defined below) (the “Spectrum Assets”) of (i) Federal Communications Committee, “FCC” licenses sufficient to operate a nationwide dispatch network in the 900 MHz band and (ii) certain 900 MHz equipment. The company is now focused on deploying a dedicated, wide-area, two-way radio network services that include cloud-based mobile work-force management solutions. Over time, the company intends to deploy the network in 20 major metropolitan areas throughout the United States, with the first markets to be located in the South and Northeast regions, with additional markets to be located in the Midwest, Southwest and West Coast regions, and to focus on serving dispatch-centric, small and medium-sized businesses. For this targeted set of customers, the company intends to offer its DispatchPlus communication solution. DispatchPlus will combine Motorola Solutions Inc.’s and its subsidiaries’ (collectively, “Motorola”) state-of-the-art digital radio technology with pdvConnect. Built with the commercial dispatch user in mind, the Motorola Digital Technology architecture will allow the company to provide a highly reliable, instant and wide-area PTT communication solution. Also developed for dispatch-centric businesses, pdvConnect is an easy to use and efficient workforce management solution that enables businesses to locate and communicate with field workers and improve documentation of work events and job status.
	The company has historically funded operations through the issuance of debt and equity instruments.
	During the year ended March 31, 2015, the company:
	Entered into an Asset Purchase Agreement with certain wholly-owned subsidiaries of Sprint Corporation (the “Sprint APA”) to purchase the nationwide Spectrum Assets for a total of $100.0 million, with $90.0 million paid in cash from the proceeds of the private placement the company completed in June 2014 (the “June 2014 Private Placement”) (see below) and $10.0 million paid in 500,000 shares of common stock (at a price equal to $20.00 per share).
	Completed the June 2014 Private Placement, on June 10, 2014, in which the company sold 10,925,000 shares of common stock at a purchase price of $20.00 per share. The net proceeds from the June 2014 Private Placement after deducting expenses including professional fees and the payment of initial placement fees, were approximately $202 million. Approximately 96% of the net proceeds, or approximately $196 million (net of any initial purchaser’s /placement agent’s discount and placement fees), were held in trust until the closing of the Sprint APA. In September 2014, a portion of the proceeds from the sale of common stock was used to:
		•	Pay the outstanding working capital line for $1,470,000 (see note 7) and $351,073 in accrued interest with 65,000 shares of common stock and $521,073 in cash;
		•	Pay the promissory note of $540,000 (see note 7) and $272,842 in accrued interest in cash;
		•	Pay the outstanding Series AA convertible promissory notes owed to certain employees for $423,852 and $283,856 (see note 7) in accrued interest in cash;
		•	Pay $367,695 owed to certain employees for deferred compensation in cash (see note 6); and
		•	Convert the Redeemable Notes (as defined in note 7 below) of $1,016,956 into 77,733 shares of common stock based on 140% of the outstanding principal and accrued interest.
	Closed agreements with Motorola on September 15, 2014, under which Motorola invested $10.0 million to purchase 500,000 Class B Units of the company’s subsidiary, PDV Spectrum Holding Company, LLC (at a price equal to $20.00 per unit) and leased some of the Spectrum Assets for a prepaid price of $7.5 million.
	Issued 1,390,957 stock options to purchase the company’s common stock and 83,804 restricted units of the company’s common stock.
	In connection with the June 2014 Private Placement, the company completed a number of actions, including:
		•	The reincorporation of the company from California to Delaware;
		•	The conversion of all outstanding shares of the company’s Series AA Preferred Stock into 748,722 shares of the company’s common stock, the exchange of 661,581 outstanding warrants to purchase shares of Series AA Preferred Stock into 29,809 shares of common stock, and the conversion of the remaining options and warrants to purchase shares of the company’s Series AA Preferred Stock into options or warrants to purchase shares of common stock and the conversion of restricted stock units for shares of its Series AA Preferred Stock into restricted stock units for shares of common stock;
		•	The amendment of outstanding Redeemable Notes, in the aggregate principal of $1,016,956, to provide that the Redeemable Notes would automatically be converted at the closing of the Sprint APA into that number of shares of common stock equal to the sum of 140% of the principal plus the outstanding interest on such Redeemable Notes through the conversion divided by $20.00 per share;
		•	A 33.11451201-for-1 reverse stock split of all outstanding common stock, which was effected immediately prior to the completion of the June 2014 Private Placement. All share and per share data reported and disclosed in the accompanying financial statements have been retroactively adjusted to give effect to the reverse stock split.
		•	Entered into an agreement with Motorola on May 12, 2014, under which Motorola agreed to provide the company with their digital radio technology and handsets that it intends to deploy as part of the nationwide network.
		•	An increase in the authorized shares of common stock to 100,000,000 shares and preferred stock to 10,000,000 shares, and a change in the par value of the company’s common stock from no par value to $0.0001 per share. The preferred stock has first priority on liquidation preference over the common stock.
	On January 26, 2015, the Securities and Exchange Commission (“SEC”) declared effective the company’s registration statement on Form S-1 relating to the resale of 11,925,000 shares of common stock held by the selling stockholders (including 500,000 shares of common stock issuable upon the conversion of the Class B Units of the company’s subsidiary, PDV Spectrum Holding Company, LLC issued to Motorola). The company received no proceeds from any sales by the selling stockholders. On February 3, 2015, shares of the company’s common stock were listed for trading on The NASDAQ Capital Market under the symbol “PDVW”.
	Also, on January 26, 2015, the company completed a private placement with a secondary closing on January 30, 2015. The company sold 57,470 shares of common stock at a purchase price of $25.00 per share to certain accredited investors in reliance on exemptions from registration under the Securities Act. The net proceeds from the January 2015 Private Placement were approximately $1,386,000. The purpose of this private placement was to secure additional round lot stockholders to enable the company to satisfy the initial listing standards of The NASDAQ Capital Market. The company intends to use the net proceeds for general corporate purposes, including working capital.

Summary_of_Significant_Account

Summary of Significant Accounting Policies	12 Months Ended
	Mar. 31, 2015
Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2	Summary of Significant Accounting Policies
	Basis of Presentation and Use of Estimates
	The financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”), which requires management to make 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 period. The most significant estimates relate to estimated useful lives of depreciable assets, allowance for doubtful accounts, valuation allowance on the company’s deferred tax assets, and recoverability of intangible assets. The company is also required to make certain estimates with regard to the valuation of awards and forfeiture rates for its share-based award programs. Estimates and assumptions are reviewed periodically and the effects of revision are reflected in the financial statements in the period they are deemed to be necessary. Accordingly actual results could differ from those estimates.
	The accompanying consolidated financial statements include the accounts of the company and its wholly-owned subsidiary, PDV Spectrum Holding Company, LLC. All significant intercompany accounts and transactions have been eliminated in consolidation.
	Reclassifications
	Certain prior year amounts have been reclassified to conform to the financial statements for the year ended March 31, 2015 financial statement presentation. These reclassifications had no effect on previously reported results of operations, cash flows, assets, liabilities or equity for the years presented.
	Cash and cash equivalents
	All highly liquid investments with maturities of three months or less of the time of purchase are considered cash equivalents. Cash equivalents are stated at cost, which approximates quoted market value and include amounts held in money market funds.
	Allowance for Uncollectible Receivables
	An allowance for uncollectible receivables is estimated based on a combination of write-off history, aging analysis and any specific known troubled accounts. The company reviews its allowance for uncollectible receivables on a quarterly basis. Past due balances meeting specific criteria are reviewed individually for collectability. At March 31, 2015 and March 31, 2014, management provided an allowance of $7,977 and $12,619, respectively, for certain slow paying accounts.
	Furniture, Fixture and Equipment
	Furniture, fixture and equipment is stated at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets.
	The carrying amount at the balance sheet date of long-lived assets under construction in process include construction costs to date on capital projects that have not been completed and assets being constructed that are not ready to be placed into service. These costs will be transferred to furniture, fixture and equipment when substantially all of the activities necessary to prepare the assets for their intended use are completed. Depreciation commences upon completion.
	Intangible Assets
	Intangible assets are wireless licenses that will be used to provide the exclusive right to utilize designated radio frequency spectrum to provide wireless communication services. While licenses are issued for only a fixed time, generally ten years, such licenses are subject to renewal by the Federal Communications Commission (“FCC”). License renewals have occurred routinely and at nominal cost. There are currently no legal, regulatory, contractual, competitive, economic or other factors that limit the useful life of the company’s wireless licenses. As a result, the wireless licenses are treated as an indefinite-lived intangible asset. The company evaluates the useful life determination for wireless licenses each year to determine whether events and circumstances continue to support an indefinite useful life. The licenses are tested for impairment on an aggregate basis, as the company will be utilizing the wireless licenses on an integrated basis as a part of developing our nationwide network. The company performs the test of the fair values of wireless licenses annually using a discounted cash flow approach.
	Patent Costs
	Costs to acquire a patent on certain aspects of the company’s technology have been capitalized. These amounts are amortized, subject to periodic evaluation for impairment, over statutory lives following award of the patent. Gross patent costs are $558,696 at March 31, 2015 and $556,052 at March 31, 2014 and the associated accumulated amortization amounted to $337,914 and $303,305, respectively. Amortization expense was $34,609, $42,830, and $37,510 for the years ended March 31, 2015, 2014 and 2013, respectively. The amortization expense is estimated to aggregate $35,000 per year over the next five year period.
	Long-Lived Asset Impairment
	The company evaluates long-lived assets, other than intangible assets with indefinite lives, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. Asset groups are determined at the lowest level for which identifiable cash flows are largely independent of cash flows of other groups of assets and liabilities. When the carrying amount of a long-lived asset group is not recoverable and exceeds its fair value, an impairment loss is recognized equal to the excess of the asset group’s carrying value over the estimated fair value.
	Fair Value of Financial Instruments
	Financial instruments, including cash, accounts receivable, accounts payable, accrued expenses and notes payable – affiliated entities are carried at cost, which management believes approximates fair value because of the short term maturity of these instruments.
	Revenue Recognition
	The company recognizes revenue in the period in which the services are provided and when collectability of the revenue is reasonably assured. In accordance with the guidance provided in Accounting Standards Codification (“ASC”) Topic 605-45-45, Revenue Recognition – Principal Agent Considerations, the company has determined that it is the primary obligor with respect to the service revenue derived from sales of the company’s software applications through its domestic carrier partners. As a result, revenue is recorded at the gross amount billed to end-user customers for sales to the domestic carrier partners. The company recognizes revenue for its international carrier on the net amount billed since it has determined that it is not the primary obligor. The company also sells certain applications directly to end-users through its direct sales force, which are billed and collected directly by the company.
	In September 2014, Motorola made an upfront, fully-paid leasing fee of $7.5 million in order to lease a portion of the company’s FCC licenses. The payment of the fee was accounted for as Deferred Revenue as of September 30, 2014. The company recognizes leasing revenue in accordance with ASC Topic 840, Leases. The fee is amortized using the straight-line method over the lease term of approximately ten years which represents the time frame in which the benefits of the leased property are expected to be depleted.
	Cost of Revenue
	The company’s cost of revenue includes the portion of service revenue retained by its domestic carrier partners pursuant to its agreements with these parties, which may include network services, connectivity, SMS service and special equipment expenses, sales, marketing, billing and other ancillary services. The company also includes the costs associated with the operation of its cloud-based solutions and dispatch network.
	Shipping and Handling Costs
	Costs associated to shipping and handling of two-way radios to dealers or end-user customers are recognized as incurred and included in cost of revenue in the statements of operations.
	Indirect Sales Commissions
	Cash consideration given to a dealer is presumed to be a reduction of revenue unless the company receives, or will receive, an identifiable benefit in exchange for the consideration, and the fair value of such benefit can be reasonably estimated, in which case the consideration will be recorded as a selling expense. The company will compensate its indirect sales representatives with an upfront commission and residual fees based on a customer’s continued use of its network solutions. When a commission is earned solely due to the selling activity relating to the company’s network solution, the cost is recorded as a selling expense. Estimated incentives payable to the indirect sales representatives will be regularly reviewed and recorded as accrued expenses on a monthly basis.
	Product Development Costs
	The company charges all product and development costs to expense as incurred. Types of expense incurred in product and development include employee compensation, consulting, travel, facility costs and equipment and technology costs.
	Advertising and Promotional Expense
	The company expenses advertising and promotional costs as incurred. Cooperative advertising reimbursements from vendors are recorded net of advertising and promotional expense in the period in which the related advertising and promotional expense is incurred. In 2015, 2014 and 2013, no advertising costs were incurred.
	Stock Compensation
	The company accounts for stock options in accordance with US GAAP, which requires the measurement and recognition of compensation expense, based on the estimated fair value of awards granted to employees and directors. The company estimates the fair value of share-based awards on the date of grant using an option-pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as expense in the company’s statements of operations over the requisite service periods.
	To calculate option-based compensation, the company uses the Black-Scholes option-pricing model. The company’s determination of fair value of option-based awards on the date of grant using Black-Scholes model is affected by assumptions regarding a number of subjective variables.
	No tax benefits were attributed to the share-based compensation expense because a full valuation allowance was maintained for all net deferred tax assets.
	Income Taxes
	The company follows the liability method of accounting for income taxes. Under this method, taxes consist of taxes currently payable plus those deferred due to temporary differences between the financial statement carrying amounts and the tax bases of certain assets and liabilities using tax rates expected to be in effect when the temporary differences reverse. A valuation allowance is provided when it is more likely than not that some portion or the entire deferred tax asset will not be realized.
	Accounting for Uncertainty in Income Taxes
	The company recognizes the effect of tax positions only when they are more likely than not to be sustained. Management has determined that the company had no uncertain tax positions that would require financial statement recognition or disclosure. The company is no longer subject to U.S. federal, state or local income tax examinations for periods prior to 2012.
	Net Loss Per Share of Common Stock
	Basic net loss per common share is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period, without consideration for potentially dilutive securities. For purposes of the diluted net loss per share calculation, preferred stock, convertible notes payable-affiliated entities, stock options and warrants are considered to be potentially dilutive securities. Because the company has reported a net loss for the years ended March 31, 2015 and 2014, diluted net loss per common share is the same as basic net loss per common share for those periods.
	Common stock equivalents resulting from potentially dilutive securities approximated 1,000,000, 1,630,000 and 1,589,000 at March 31, 2015, 2014 and 2013, respectively, and have not been included in the dilutive weighted average shares of common stock outstanding, as their effects are anti-dilutive.
	Recently Issued Accounting Pronouncements
	In May 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-09 Revenue from Contracts with Customers (Topic 606), which supersedes the revenue recognition requirements in ASC 605, Revenue Recognition. This ASU is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The ASU also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. This guidance is effective for interim and annual periods beginning on or after December 15, 2016. The company is currently evaluating the impact of the adoption of this accounting standard update on its financial statements.
	In April 2015, FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs, which changes the presentation of debt issuance costs in the financial statements. ASU 2015-03 requires an entity to present such costs in the balance sheet as a direct deduction from the related debt liability rather than as an asset. Amortization of the costs will continue to be reported as interest expense. The guidance is effective for annual reporting periods beginning after December 15, 2016, with early adoption permitted. The guidance will be applied retrospectively to each period presented. The adoption of this standard update is not expected to have any impact on the company’s financial statements.
	Subsequent Events Evaluation by Management
	Management has evaluated subsequent events for disclosure and/or recognition in the financial statements through the date that the financial statements were issued.

	The company had federal and state net operating loss carryforwards of approximately $28.7 million at March 31, 2015 expiring in varying amounts from 2021 and through 2035.
	The company has deferred tax assets of approximately $14.7 million and $8.5 million relating to these net operating loss carryforwards and deferred compensation plans at March 31, 2015 and 2014, respectively. Federal net operating loss carryforwards are subject to limitations as a result of the change in ownership (see note 1) as defined under Internal Revenue Code Section 382. State net operating loss carryforwards are subject to limitations which differ from federal law in that they may not allow the carryback of net operating losses, and have shorter carryforward periods. Due to the uncertainty with respect to the realization of these deferred tax assets the company recorded a valuation allowance for the entire amount. The difference between the tax benefit at the statutory rate and the effective tax rate is attributable to a full valuation allowance placed upon the deferred tax asset.

	The company established the Pacific DataVision 2014 Stock Plan (the “2014 Stock Plan”) to attract, retain and reward individuals who contribute to the growth and profitability of the company. This Stock Plan superseded previous stock plans although under such previous plans, 74,134 stock options were vested and outstanding as of March 31, 2015.
	The company’s Board of Directors authorized and reserved 1,823,651 shares of common stock for issuance under its 2014 Stock Plan. The number of shares reserved for future issuance under the 2014 Stock Plan automatically increased on January 1, 2015 by 623,651. The number of shares will continue to automatically increase each subsequent anniversary through January 1, 2024 by an amount equal to the smaller of 5% of the number of shares of common stock issued and outstanding on the immediately preceding December 31 or a lesser amount determined by the Board of Directors.
	From May 14, 2014 through March 31, 2015, the company awarded certain employees and contractors of the company 1,390,957 options to purchase shares of common stock with a weighted average exercise price of $20.93 per share. The shares have a ten year contractual life and 25% will vest on the first anniversary of grant, and the remainder will vest in three equal annual installments. Shares granted to employees are subject to vesting, future settlement conditions and other such terms as determined by the Board of Directors.
	In connection with the June 2014 Private Placement, the company converted all outstanding shares of the company’s Series AA Preferred Stock into 748,722 shares of its common stock, exchanged 661,581 outstanding warrants to purchase shares of Series AA Preferred Stock into 29,809 shares of common stock, and converted the remaining options and warrants to purchase shares of the Series AA Preferred Stock into options or warrants to purchase shares of the common stock, and converted restricted stock units for shares of the company’s Series AA Preferred Stock into restricted stock units for shares of common stock.
	Restricted Stock Units
	Under the 2010 Stock Plan, the company issued 82,054 restricted stock units and under the 2014 Stock Plan, the company issued 1,750 restricted stock units, for shares of the company’s common stock, during the year ended March 31, 2015 to certain employees and contractors of the company. The company recognizes compensation expense for restricted stock units over the explicit vesting period. Vested restricted stock units are settled and issuable upon the earlier of the date the employee ceases to be an employee of the company or a date certain in the future. Stock compensation expense related to the 83,804 shares issued in the year ended March 31, 2015 was $1,676,080. At March 31, 2015, 128,001 restricted stock units were vested.
	During Fiscal 2013, the company granted 301 shares of restricted stock units to one employee which vested immediately. Stock compensation expense related to the 301 shares issued in Fiscal 2013 was not material. There were no restricted stock units issued during Fiscal 2014. There were 44,197 shares of Series AA Preferred Stock in the form of restricted stock units that were granted under the 2010 Stock Plan and were vested as of March 31, 2014.

	The fair value of options granted is estimated on the date of grant using the Black-Scholes option valuation model. This stock-based compensation expense valuation model requires the company to make assumptions and judgments regarding the variables used in the calculation. These variables include the expected term, the expected volatility of the company’s common stock, expected risk-free interest rate, forfeiture rate and expected dividends. The company calculates it expected term and volatility from the historical volatilities and terms of selected comparable public companies within its industry, due to the lack of historical information regarding those variables. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for periods corresponding with the expected life of the option. The company estimates its forfeiture rate based on an analysis of its actual forfeitures and will continue to evaluate the appropriateness of the forfeiture rate based on actual forfeiture experience, analysis of employee turnover and other factors. The company has never paid, and does not anticipate paying, any cash dividends in the foreseeable future, and therefore uses an expected dividend yield of zero in the option-pricing model.
	The following assumptions were used to calculate the fair value of options:
			Year Ended
			March 31, 2015
	Risk-free interest rate		1.28% to 1.66%
	Dividend yield		—  %
	Volatility		40% to 47%
	Expected term		5 years
	Stock compensation expense totaled $6,963,782, $79,057, and $82,438 for the years ended March 31, 2015, 2014, and 2013 respectively. For the year ended March 31, 2015, $1,676,080 in expense was related to the restricted stock units issued in the year ended March 31, 2015. The balance of stock compensation expense for each of the three years ended March 31, 2015 is related to the amortization of the fair value of options issued since fiscal year 2009. Stock compensation expense is included as part of general and administrative expense in the accompanying statement of operations. The weighted average fair value for the stock option awards granted for the fiscal year ended March 31, 2015 was $8.62. As of March 31, 2015, there was approximately $6.8 million of unrecognized compensation cost related to non-vested share options granted under the company’s stock option plans. The cost is expected to be recognized over a weighted-average period of 3.3 years. The intrinsic value of the options outstanding and exercisable at March 31, 2015 was approximately $41.5 million and $4.8 million, respectively.

	Motorola Investment
	On September 15, 2014, Motorola invested $10.0 million to purchase 500,000 Class B Units of the company’s subsidiary, PDV Spectrum Holding Company, LLC (at a price equal to $20.00 per unit). The company owns
	100% of the Class A Units in this subsidiary. Motorola has the right at any time to convert its 500,000 Class B Units into 500,000 shares of the company’s common stock. The company also has the right to force Motorola’s conversion into shares of its common stock on the occurrence of certain corporate events or at its election after September 15, 2016. Motorola is not entitled to any assets, profits or distributions from the operations of the subsidiary. In addition, Motorola’s conversion ratio from Class B Units to shares of the Company’s common stock is fixed on a one-for-one basis, and is not dependent on the performance or valuation of either the company or the subsidiary. The Class B Units have no redemption or call provisions and can only be converted into shares of the company’s common stock. Management has determined that this investment does not meet the criteria for temporary equity or non-controlling interest due to the limited rights that Motorola has as a holder of Class B Units, and accordingly has presented this investment as part of its permanent equity within Additional Paid-in Capital in the accompanying financial statements.

	The Severance Plan establishes three tiers of executives: Tier 1, Tier 2 and Tier 3. Within each tier the Severance Plan stipulates the payments due each employee, the effect of equity awards granted, and the provisions for health insurance.
	Litigation
	The company is not involved in any legal proceedings or other legal matters at this time. However, from time to time, the company may be involved in litigation that arises from the ordinary operations of the business, such as contractual or employment disputes or other general actions. In the event of an adverse outcome of these proceedings, the company believes the resulting liabilities would not have a material adverse effect on its financial condition or results of operations.

Summary_of_Significant_Account1

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Mar. 31, 2015
Accounting Policies [Abstract]
Basis of Presentation and Use of Estimates	Basis of Presentation and Use of Estimates
	The financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”), which requires management to make 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 period. The most significant estimates relate to estimated useful lives of depreciable assets, allowance for doubtful accounts, valuation allowance on the company’s deferred tax assets, and recoverability of intangible assets. The company is also required to make certain estimates with regard to the valuation of awards and forfeiture rates for its share-based award programs. Estimates and assumptions are reviewed periodically and the effects of revision are reflected in the financial statements in the period they are deemed to be necessary. Accordingly actual results could differ from those estimates.
	The accompanying consolidated financial statements include the accounts of the company and its wholly-owned subsidiary, PDV Spectrum Holding Company, LLC. All significant intercompany accounts and transactions have been eliminated in consolidation.
Reclassifications	Reclassifications
	Certain prior year amounts have been reclassified to conform to the financial statements for the year ended March 31, 2015 financial statement presentation. These reclassifications had no effect on previously reported results of operations, cash flows, assets, liabilities or equity for the years presented.
Cash and cash equivalents	Cash and cash equivalents
	All highly liquid investments with maturities of three months or less of the time of purchase are considered cash equivalents. Cash equivalents are stated at cost, which approximates quoted market value and include amounts held in money market funds.
Allowance for Uncollectible Receivables	Allowance for Uncollectible Receivables
	An allowance for uncollectible receivables is estimated based on a combination of write-off history, aging analysis and any specific known troubled accounts. The company reviews its allowance for uncollectible receivables on a quarterly basis. Past due balances meeting specific criteria are reviewed individually for collectability. At March 31, 2015 and March 31, 2014, management provided an allowance of $7,977 and $12,619, respectively, for certain slow paying accounts.
Furniture, Fixture and Equipment	Furniture, Fixture and Equipment
	Furniture, fixture and equipment is stated at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets.
	The carrying amount at the balance sheet date of long-lived assets under construction in process include construction costs to date on capital projects that have not been completed and assets being constructed that are not ready to be placed into service. These costs will be transferred to furniture, fixture and equipment when substantially all of the activities necessary to prepare the assets for their intended use are completed. Depreciation commences upon completion.
Intangible Assets	Intangible Assets
	Intangible assets are wireless licenses that will be used to provide the exclusive right to utilize designated radio frequency spectrum to provide wireless communication services. While licenses are issued for only a fixed time, generally ten years, such licenses are subject to renewal by the Federal Communications Commission (“FCC”). License renewals have occurred routinely and at nominal cost. There are currently no legal, regulatory, contractual, competitive, economic or other factors that limit the useful life of the company’s wireless licenses. As a result, the wireless licenses are treated as an indefinite-lived intangible asset. The company evaluates the useful life determination for wireless licenses each year to determine whether events and circumstances continue to support an indefinite useful life. The licenses are tested for impairment on an aggregate basis, as the company will be utilizing the wireless licenses on an integrated basis as a part of developing our nationwide network. The company performs the test of the fair values of wireless licenses annually using a discounted cash flow approach.
Patent Costs	Patent Costs
	Costs to acquire a patent on certain aspects of the company’s technology have been capitalized. These amounts are amortized, subject to periodic evaluation for impairment, over statutory lives following award of the patent. Gross patent costs are $558,696 at March 31, 2015 and $556,052 at March 31, 2014 and the associated accumulated amortization amounted to $337,914 and $303,305, respectively. Amortization expense was $34,609, $42,830, and $37,510 for the years ended March 31, 2015, 2014 and 2013, respectively. The amortization expense is estimated to aggregate $35,000 per year over the next five year period.
Long-Lived Asset Impairment	Long-Lived Asset Impairment
	The company evaluates long-lived assets, other than intangible assets with indefinite lives, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. Asset groups are determined at the lowest level for which identifiable cash flows are largely independent of cash flows of other groups of assets and liabilities. When the carrying amount of a long-lived asset group is not recoverable and exceeds its fair value, an impairment loss is recognized equal to the excess of the asset group’s carrying value over the estimated fair value.
Fair Value of Financial Instruments	Fair Value of Financial Instruments
	Financial instruments, including cash, accounts receivable, accounts payable, accrued expenses and notes payable – affiliated entities are carried at cost, which management believes approximates fair value because of the short term maturity of these instruments.
Revenue Recognition	Revenue Recognition
	The company recognizes revenue in the period in which the services are provided and when collectability of the revenue is reasonably assured. In accordance with the guidance provided in Accounting Standards Codification (“ASC”) Topic 605-45-45, Revenue Recognition – Principal Agent Considerations, the company has determined that it is the primary obligor with respect to the service revenue derived from sales of the company’s software applications through its domestic carrier partners. As a result, revenue is recorded at the gross amount billed to end-user customers for sales to the domestic carrier partners. The company recognizes revenue for its international carrier on the net amount billed since it has determined that it is not the primary obligor. The company also sells certain applications directly to end-users through its direct sales force, which are billed and collected directly by the company.
	In September 2014, Motorola made an upfront, fully-paid leasing fee of $7.5 million in order to lease a portion of the company’s FCC licenses. The payment of the fee was accounted for as Deferred Revenue as of September 30, 2014. The company recognizes leasing revenue in accordance with ASC Topic 840, Leases. The fee is amortized using the straight-line method over the lease term of approximately ten years which represents the time frame in which the benefits of the leased property are expected to be depleted.
Cost of Revenue	Cost of Revenue
	The company’s cost of revenue includes the portion of service revenue retained by its domestic carrier partners pursuant to its agreements with these parties, which may include network services, connectivity, SMS service and special equipment expenses, sales, marketing, billing and other ancillary services. The company also includes the costs associated with the operation of its cloud-based solutions and dispatch network.
Shipping and Handling Costs	Shipping and Handling Costs
	Costs associated to shipping and handling of two-way radios to dealers or end-user customers are recognized as incurred and included in cost of revenue in the statements of operations.
Indirect sales commissions	Indirect Sales Commissions
	Cash consideration given to a dealer is presumed to be a reduction of revenue unless the company receives, or will receive, an identifiable benefit in exchange for the consideration, and the fair value of such benefit can be reasonably estimated, in which case the consideration will be recorded as a selling expense. The company will compensate its indirect sales representatives with an upfront commission and residual fees based on a customer’s continued use of its network solutions. When a commission is earned solely due to the selling activity relating to the company’s network solution, the cost is recorded as a selling expense. Estimated incentives payable to the indirect sales representatives will be regularly reviewed and recorded as accrued expenses on a monthly basis.
Product Development Costs	Product Development Costs
	The company charges all product and development costs to expense as incurred. Types of expense incurred in product and development include employee compensation, consulting, travel, facility costs and equipment and technology costs.
Advertising and Promotional Expense	Advertising and Promotional Expense
	The company expenses advertising and promotional costs as incurred. Cooperative advertising reimbursements from vendors are recorded net of advertising and promotional expense in the period in which the related advertising and promotional expense is incurred. In 2015, 2014 and 2013, no advertising costs were incurred.
Stock Compensation	Stock Compensation
	The company accounts for stock options in accordance with US GAAP, which requires the measurement and recognition of compensation expense, based on the estimated fair value of awards granted to employees and directors. The company estimates the fair value of share-based awards on the date of grant using an option-pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as expense in the company’s statements of operations over the requisite service periods.
	To calculate option-based compensation, the company uses the Black-Scholes option-pricing model. The company’s determination of fair value of option-based awards on the date of grant using Black-Scholes model is affected by assumptions regarding a number of subjective variables.
	No tax benefits were attributed to the share-based compensation expense because a full valuation allowance was maintained for all net deferred tax assets.
Income Taxes	Income Taxes
	The company follows the liability method of accounting for income taxes. Under this method, taxes consist of taxes currently payable plus those deferred due to temporary differences between the financial statement carrying amounts and the tax bases of certain assets and liabilities using tax rates expected to be in effect when the temporary differences reverse. A valuation allowance is provided when it is more likely than not that some portion or the entire deferred tax asset will not be realized.
Accounting for Uncertainty in Income Taxes	Accounting for Uncertainty in Income Taxes
	The company recognizes the effect of tax positions only when they are more likely than not to be sustained. Management has determined that the company had no uncertain tax positions that would require financial statement recognition or disclosure. The company is no longer subject to U.S. federal, state or local income tax examinations for periods prior to 2012.
Net Loss Per Share of Common Stock	Net Loss Per Share of Common Stock
	Basic net loss per common share is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period, without consideration for potentially dilutive securities. For purposes of the diluted net loss per share calculation, preferred stock, convertible notes payable-affiliated entities, stock options and warrants are considered to be potentially dilutive securities. Because the company has reported a net loss for the years ended March 31, 2015 and 2014, diluted net loss per common share is the same as basic net loss per common share for those periods.
	Common stock equivalents resulting from potentially dilutive securities approximated 1,000,000, 1,630,000 and 1,589,000 at March 31, 2015, 2014 and 2013, respectively, and have not been included in the dilutive weighted average shares of common stock outstanding, as their effects are anti-dilutive.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements
	In May 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-09 Revenue from Contracts with Customers (Topic 606), which supersedes the revenue recognition requirements in ASC 605, Revenue Recognition. This ASU is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The ASU also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. This guidance is effective for interim and annual periods beginning on or after December 15, 2016. The company is currently evaluating the impact of the adoption of this accounting standard update on its financial statements.
	In April 2015, FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs, which changes the presentation of debt issuance costs in the financial statements. ASU 2015-03 requires an entity to present such costs in the balance sheet as a direct deduction from the related debt liability rather than as an asset. Amortization of the costs will continue to be reported as interest expense. The guidance is effective for annual reporting periods beginning after December 15, 2016, with early adoption permitted. The guidance will be applied retrospectively to each period presented. The adoption of this standard update is not expected to have any impact on the company’s financial statements.
