	2. Summary of significant accounting policies
	Basis of presentation
	The accompanying interim unaudited condensed consolidated financial statements and related notes for the three and six months ended June 30, 2014 and 2013 are unaudited. The unaudited interim condensed consolidated financial information has been prepared in accordance with the rules and regulations of the SEC for interim financial information. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles (“GAAP”) in the United States of America (“U.S.”) for complete financial statements. These financial statements should be read in conjunction with the audited consolidated financial statements and the accompanying notes for the year ended December 31, 2013 contained in our annual report on Form 10-K filed with the SEC on March 17, 2014. The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the annual consolidated financial statements and in the opinion of management, reflects all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of our results of operations and cash flows for the three and six months ended June 30, 2014 and 2013, and our financial position as of June 30, 2014. The year-end balance sheet data was derived from audited consolidated financial statements, but does not include all disclosures required by GAAP. Interim results are not necessarily indicative of the results to be expected for an entire year or any other future year or interim period.
	Principles of consolidation
	The unaudited condensed consolidated financial statements include our accounts and the accounts of our majority owned subsidiaries. We consolidate our 70% ownership of Concourse Communications Detroit, LLC, our 70% ownership of Chicago Concourse Development Group, LLC and our 75% ownership of Boingo Holding Participacoes Ltda. in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 810, Consolidation. Other parties’ interests in consolidated entities are reported as non-controlling interests. All intercompany balances and transactions have been eliminated in consolidation.
	Business combinations
	The results of businesses acquired in a business combination are included in the Company’s condensed consolidated financial statements from the date of the acquisition. Purchase accounting results in assets and liabilities of an acquired business being recorded at their estimated fair values on the acquisition date. Any excess consideration over the fair value of assets acquired and liabilities assumed is recognized as goodwill.
	The Company performs valuations of assets acquired and liabilities assumed for a business acquisition and allocates the purchase price to its respective net tangible and intangible assets. Determining the fair value of assets acquired and liabilities assumed requires management to use significant judgment and estimates including the selection of valuation methodologies, estimates of future revenues and cash flows, discount rates, royalty rates and selection of comparable companies. The Company engages the assistance of valuation specialists in concluding on fair values of assets and liabilities assumed in a business combination.
	Transaction costs associated with business combinations are expensed as incurred, and are included in general and administrative expenses in the condensed consolidated statements of operations. There were no significant transaction costs associated with business combinations for the three and six months ended June 30, 2014. Transaction costs associated with business combinations were $34 and $192 for the three and six months ended June 30, 2013, respectively.
	Segment and geographical information
	We operate as one reportable segment; a service provider of mobile Internet solutions across our managed and operated network and aggregated network for mobile devices such as laptops, smartphones, tablet computers and other wireless-enabled consumer devices. This single segment is consistent with the internal organization structure and the manner in which operations are reviewed and managed by our Chief Executive Officer, the chief operating decision maker.
	Revenue is predominately generated and all significant long-lived tangible assets are held in the U.S. We do not disclose sales by geographic area because to do so would be impracticable. The following is a summary of our revenue by primary revenue source:
		Three Months Ended				Six Months Ended
		June 30,				June 30,
		2014		2013		2014		2013
	Revenue:
	Wholesale	$	12,872	$	12,339	$	23,995	$	23,894
	Retail subscription	8,161		8,731		16,455		16,798
	Retail single-use	2,830		2,830		5,366		5,416
	Advertising and other	4,533		2,339		9,032		3,265
	Total revenue	$	28,396	$	26,239	$	54,848	$	49,373
	Marketable securities
	Our marketable securities consist of available-for-sale securities with original maturities exceeding three months. In accordance with FASB ASC 320, Investments—Debt and Equity Securities, we have classified securities, which have readily determinable fair values and are highly liquid, as short-term because such securities are expected to be realized within a one-year period. At June 30, 2014 and December 31, 2013, we had $29,909 and $32,962, respectively, in marketable securities.
	Marketable securities are reported at fair value with the related unrealized gains and losses reported as other comprehensive income (loss) until realized or until a determination is made that an other-than-temporary decline in market value has occurred. No significant unrealized gains and losses have been reported during the periods presented. Factors considered by us in assessing whether an other-than-temporary impairment has occurred include the nature of the investment, whether the decline in fair value is attributable to specific adverse conditions affecting the investment, the financial condition of the investee, the severity and the duration of the impairment and whether we have the ability to hold the investment to maturity. When it is determined that an other-than-temporary impairment has occurred, the investment is written down to its market value at the end of the period in which it is determined that an other-than-temporary decline has occurred. The cost of marketable securities sold is based upon the specific identification method. Any realized gains or losses on the sale of investments are reflected as a component of interest and other (expense) income, net.
	For the six months ended June 30, 2014, we had no significant realized or unrealized gains or losses from investments in marketable securities classified as available-for-sale.
	Revenue recognition
	We generate revenue from several sources including: (i) platform service arrangements with wholesale customers that provide software licensing, network access, and professional services fees, (ii) wholesale customers that are telecom operators under long-term contracts for access to our DAS at our managed and operated locations, (iii) retail customers under subscription plans for month-to-month network access that automatically renew, and retail single-use access from sales of hourly, daily or other single-use access plans, and (iv) display advertisements and sponsorships on our walled garden sign-in pages. Software licensed by our wholesale platform services customers can only be used during the term of the service arrangements and has no utility to them upon termination of the service arrangement.
	We recognize revenue when an arrangement exists, services have been rendered, fees are fixed or determinable, no significant obligations remain related to the earned fees and collection of the related receivable is reasonably assured.
	Services provided to wholesale partners under platform service arrangements generally contain several elements including: (i) a term license to use our software to access our Wi-Fi network, (ii) access fees for network usage, and (iii) professional services for software integration and customization and to maintain the Wi-Fi service. The term license, monthly minimum network access fees and professional services are billed on a monthly basis based upon predetermined fixed rates. Once the term license for integration and customization are delivered, the fees from the arrangement are recognized ratably over the remaining term of the platform service arrangement. The initial term of platform service license agreements is generally between one to five years and the agreements generally contain renewal clauses. Revenue for network access fees in excess of the monthly minimum amounts is recognized when earned. All elements within existing platform service arrangements are generally delivered and earned concurrently throughout the term of the respective service arrangement.
	Revenue generated from access to our DAS networks consists of build-out fees and recurring access fees under certain long-term contracts with telecom operators. Build-out fees paid upfront are generally deferred and recognized ratably over the term of the estimated customer relationship period, once the build-out is complete. Minimum monthly access fees for usage of the DAS networks are non-cancellable and generally escalate on an annual basis. These minimum monthly access fees are recognized ratably over the term of the telecom operator agreement. The initial term of our contracts with telecom operators and wholesale partners generally range from three to fifteen years and the agreements generally contain renewal clauses. Revenue from network access fees in excess of the monthly minimums is recognized when earned.
	In instances where the minimum monthly network access fees escalate over the term of the wholesale service arrangement, an unbilled receivable is recognized when performance is within our control and when we have reasonable assurance that the unbilled receivable balance will be collected.
	We adopted the provisions of Accounting Standards Update (“ASU”) 2009-13, Revenue Recognition (Topic 605)—Multiple-Deliverable Revenue Arrangements (“ASU 2009-13”), on a prospective basis on January 1, 2011. For multiple-deliverable arrangements entered into prior to January 1, 2011 that are accounted for under ASC 605-25, Revenue Recognition—Multiple- Deliverable Revenue Arrangements, we defer recognition of revenue for the full arrangement and recognize all revenue ratably over the wholesale service period for platform service arrangements and the term of the estimated customer relationship period for DAS arrangements, because we do not have evidence of fair value for the undelivered elements in the arrangement. For multiple-deliverable arrangements entered into or materially modified after January 1, 2011 that are accounted for under ASC 605-25, we evaluate whether or not separate units of accounting exist and then allocate the arrangement consideration to all units of accounting based on the relative selling price method using estimated selling prices because vendor specific objective evidence and third party evidence is not available. We recognize the revenue associated with the separate units of accounting upon completion of such services or ratably over the wholesale service period for platform service arrangements and the term of the estimated customer relationship period for DAS arrangements.
	Subscription fees from retail customers are paid monthly in advance and revenue is deferred for the portions of monthly recurring subscription fees collected in advance. We do not have a stated or published refund policy for our Wi-Fi service, although our customer service representatives will provide a refund on a case-by-case basis. These amounts are not significant and are recorded as contra-revenue in the period the refunds are made. Subscription fee revenue is recognized ratably over the subscription period. Revenue generated from retail single-use access is recognized when earned.
	Advertising revenue is generated from advertisements on our managed and operated or partner networks. In determining whether an arrangement exists, we ensure that a binding arrangement is in place, such as a standard insertion order or a fully executed customer-specific agreement. Obligations pursuant to our advertising revenue arrangements typically include a minimum number of units or the satisfaction of certain performance criteria. Advertising and other revenue is recognized when the services are performed.
	Recent accounting pronouncements
	On May 28, 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which is intended to improve and converge the financial reporting requirements for revenue from contracts with customers between U.S. GAAP and International Accounting Standards. In accordance with this new standard, an entity would recognize revenue to depict the transfer of promised 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 standard establishes a five-step model and related application guidance, which will replace most existing revenue recognition guidance in U.S. GAAP. The standard will be effective for annual and interim periods in fiscal years beginning after December 15, 2016. Early adoption is not permitted. An entity may choose to adopt the new standard either retrospectively or through a cumulative effect adjustment as of the start of the first period for which it applies the new standard. We are currently evaluating the expected impact of this new standard on our reporting of revenue contracts in our consolidated financial statements.

	3. Acquisitions
	Electronic Media Systems, Inc. and Advanced Wireless Group, LLC
	On October 31, 2013, we acquired all outstanding stock of Electronic Media Systems, Inc. and all membership interests in its subsidiary, Advanced Wireless Group, LLC, not otherwise owned by Electronic Media Systems, Inc. such that we are now the beneficial owner of all membership interests of Advanced Wireless, Group, LLC (collectively, “AWG”). AWG operates public Wi-Fi in seventeen U.S. airports including Los Angeles International, Charlotte/Douglas International, Miami International, Minneapolis- St. Paul International, Detroit Metropolitan Airport, and Boston’s Logan International. We have included the operating results of AWG in our condensed consolidated financial statements since the date of acquisition.
	The acquisition has been accounted for under the acquisition method of accounting in accordance with FASB ASC 805, Business Combinations. As such, the assets acquired and liabilities assumed are recorded at their acquisition-date fair values. The total purchase price was $17,527, which includes cash paid at closing, net equity adjustments, holdback consideration to be paid and the fair value of additional contingent consideration that would be due and payable upon the successful extension of a specified airport Wi-Fi contract. On July 29, 2014, we paid $147 to the previous AWG shareholders as settlement for the net equity adjustments that were not finalized as of the acquisition date.
	The fair value of the contingent consideration is based on Level 3 inputs, which are discussed in Note 6. Further changes in the fair value of the contingent consideration are recorded through operating loss. On July 29, 2014, we paid the contingent consideration in the amount of $1,000 to the previous AWG shareholders. We allocated the excess of the purchase price over the fair value of assets acquired and liabilities assumed to goodwill, which is primarily not deductible for tax purposes. The goodwill arising from the AWG acquisition is attributable primarily to expected synergies and other benefits, including the acquired workforce, from combining AWG with us.
	The deferred tax liabilities are provisional pending the filing of AWG’s final short period 2013 tax returns. The contingent consideration was valued at the date of acquisition using a discount rate of 3.1%. The identifiable intangible assets were primarily valued using the excess earnings, relief from royalty, with-and-without and replacement cost methods using discount rates ranging from 12.0% to 14.0% and royalty rates of 0.5%.
	The amortizable intangible assets are being amortized straight-line over their estimated useful lives. The following summarizes the preliminary purchase price allocation:
		Estimated Fair			Weighted Average
		Value			Estimated Useful
					Life (years)

	Cash paid	$	14,800

	Total purchase price	$	17,527
	Endeka Group, Inc.
	On February 22, 2013, we acquired all outstanding stock of Endeka Group, Inc. (“Endeka”). Endeka is a provider of commercial wireless broadband and IPTV services at certain military bases, as well as Wi-Fi services to certain federal law enforcement training facilities. We acquired Endeka because Endeka’s portfolio of venues and management team are natural additions to our managed network business. We have included the operating results of Endeka in our condensed consolidated financial statements since the date of acquisition.
	The acquisition has been accounted for under the acquisition method of accounting in accordance with FASB ASC 805. As such, the assets acquired and liabilities assumed are recorded at their acquisition-date fair values. The total purchase price was $6,498, which includes cash paid at closing, holdback consideration to be paid and the fair value of additional contingent consideration comprised of two components: (i) a payment (“Build Payment”) if the amount of the capital expenditures incurred for the substantial completion of a specified build project is less than a target; and (ii) a payment (“Milestone Payment”) based on revenue generated by certain contracts in fiscal year 2014. There is no maximum to the contingent consideration payments for the Milestone Payment. We do not expect to make any payments associated with the Build Payment. The Milestone Payment will be paid on February 28, 2015.
	The fair value of the contingent consideration is based on Level 3 inputs. Further changes in the fair value of the contingent consideration are recorded through operating (loss) income. We allocated the excess of the purchase price over the fair value of assets acquired and liabilities assumed to goodwill, which is not deductible for tax purposes. The goodwill arising from the Endeka acquisition is attributable primarily to expected synergies and other benefits, including the acquired workforce, from combining Endeka with us.
	The contingent consideration was valued at the date of acquisition using a discounted cash flow method with probability weighted cash flows and a discount rate of 50.5%. The identifiable intangible assets were primarily valued using the excess earnings, relief from royalty, and replacement cost methods using discount rates ranging from 40.0% to 50.0% and royalty rates ranging from 0.5% to 1.5%, where applicable.
	The amortizable intangible assets are being amortized straight-line over their estimated useful lives. The following summarizes the final purchase price allocation:
		Estimated Fair			Estimated Useful
		Value			Life (years)
	Consideration:
	Cash paid	$	4,894
	Holdback consideration	275
	Contingent consideration	1,329
	Total consideration	$	6,498

	ASC 820 establishes a three-tiered hierarchy that draws a distinction between market participant assumptions based on (i) quoted prices (unadjusted) in active markets for identical assets and liabilities (Level 1); (ii) inputs other than quoted prices in active markets that are observable either directly or indirectly (Level 2); and (iii) unobservable inputs that require us to use present value and other valuation techniques in the determination of fair value (Level 3). The following table sets forth our financial assets and liabilities that are measured at fair value on a recurring basis:

	Total liabilities	$	—		$	—	$	1,942	$	1,942
	Our marketable securities utilize Level 2 inputs and consist primarily of corporate securities which include commercial paper and corporate debt instruments including notes issued by foreign or domestic corporations which pay in U.S. dollars and carry a rating of A or better. We have evaluated the various types of securities in our investment portfolio to determine an appropriate fair value hierarchy level based upon trading activity and the observability of market inputs.  Due to variations in trading volumes and the lack of quoted market prices in active markets, our fixed maturities are classified as Level 2 securities. The fair value of our fixed maturity marketable securities is derived through the use of a third party pricing source using recent reported trades for identical or similar securities, making adjustments through the reporting date based upon available market observable data.
	The Company used the income approach to value the contingent consideration as of June 30, 2014. The contingent consideration used a discounted cash flow method with probability weighted cash flows for Endeka. The contingent consideration for AWG was paid out subsequent to June 30, 2014. The following table presents a reconciliation of the beginning and ending amounts related to the fair value of contingent consideration for the Endeka and AWG acquisitions, categorized as Level 3:

	8. Income taxes
	We calculate our interim income tax provision in accordance with ASC 270, Interim Reporting, and ASC 740, Accounting for Income Taxes. At the end of each interim period, we estimate the annual effective tax rate and apply that rate to our ordinary quarterly earnings. The tax expense or benefit related to significant, unusual, or extraordinary items is recognized in the interim period in which those items occur. In addition, the effect of changes in enacted tax laws, rates, or tax status is recognized in the interim period in which the change occurs.
	The computation of the annual estimated effective tax rate at each interim period requires certain estimates and significant judgment, including the expected operating income (loss) for the year, projections of the proportion of income (loss) earned and taxed in various states, permanent and temporary differences as a result of differences between amounts measured and recognized in accordance with tax laws and financial accounting standards, and the likelihood of recovering deferred tax assets generated in the current year. The accounting estimates used to compute the provision for income taxes may change as new events occur, additional information is obtained, or as the tax environment changes.
	Income tax expense (benefit) of $303 and $(640) reflects an effective tax rate of (3.6)% and 34.5% for the six months ended June 30, 2014 and 2013, respectively. Our effective tax rate differs from the statutory rate primarily due to our valuation allowance for the six months ended June 30, 2014. Our effective tax rate differs from the statutory rate primarily due to benefits from disqualifying dispositions of incentive stock options and non-tax deductible transaction costs related to the acquisition of Endeka for the six months ended June 30, 2013. At June 30, 2014, we have net deferred tax liabilities of $2,407, which include net operating loss carry-forwards. As of June 30, 2014 and December 31, 2013, we had $455 and $445, respectively, of uncertain tax positions, $106 of which is a reduction to deferred tax assets, which is presented net of uncertain tax positions, in the accompanying condensed consolidated balance sheets. We accrue interest and penalties related to unrecognized tax benefits as a component of income taxes. As of June 30, 2014 and December 31, 2013, we have accrued $63 and $53, respectively, for related interest, net of federal income tax benefits, and penalties. The amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate as of June 30, 2014 was $286.
	We are subject to taxation in the United States and in various states. Our tax years 2010 and forward are subject to examination by the IRS and our tax years 2009 and forward are subject to examination by material state jurisdictions. However, due to prior year loss carryovers, the IRS and state tax authorities may examine any tax years for which the carryovers are used to offset future taxable income. We are currently subject to examination by the IRS for our 2011 tax year. Although the ultimate outcome is unknown, we believe that any adjustments that may result from the examination is not likely to have a material, adverse effect on our condensed consolidated results of operations, financial position or cash flows.

	In March 2011, our board of directors approved the 2011 Equity Incentive Plan (“2011 Plan”).  The 2011 Plan provides for the grant of incentive and nonstatutory stock options, stock appreciation rights, restricted shares of our common stock, stock units, and performance cash awards.  As of January 1 of each year, the number of shares of common stock reserved for issuance under our stock incentive plan shall automatically be increased by a number equal to the lesser of (a) 4.5% of the total number of shares of common stock then outstanding, (b) 3,000,000 shares of common stock and (c) as determined by our board of directors.  As of June 30, 2014, 8,693,162 shares of common stock are reserved for issuance.
	No further awards will be made under our Amended and Restated 2001 Stock Incentive Plan (“2001 Plan”), and it will be terminated.  Options outstanding under the 2001 Plan will continue to be governed by their existing terms.
	Stock-based compensation expense is allocated as follows on the accompanying condensed consolidated statements of operations:

	We capitalized $126 and $161 of stock-based compensation expense during the three and six months ended June 30, 2014, respectively.
	Stock option awards
	We grant stock option awards to both employees and non-employee directors. The grant date for these awards is the same as the measurement date. The stock option awards generally vest over a four year service period with 25% vesting when the individual completes 12 months of continuous service and the balance vesting monthly thereafter subject to continuous service on each vesting date. These awards are valued as of the measurement date and the stock-based compensation expense, net of estimated and actual forfeitures, is recognized on a straight-line basis over the requisite service period.
	A summary of the stock option activity is as follows:
		Number of		Weighted			Weighted-		Aggregate
		Options (000’s)		Average			Average		Intrinsic
				Exercise			Remaining		Value

	Exercisable at June 30, 2014	2,919		$	5.27		5		$	9,005
	The significant assumptions used for newly-issued stock option grants for the six months ended June 30, 2014 were an expected term of 6.25 years, an expected volatility of 48.6%, a risk free interest rate of 1.8% and no expected dividends.  The weighted average grant date fair value for stock option grants for the six months ended June 30, 2014 was $2.92.
	Restricted stock unit awards
	During the six months ended June 30, 2014, we granted time-based restricted stock units (“RSU”) to executive and non-executive personnel and non-employee directors. The time-based RSUs granted to executive and non-executive personnel generally vest over a two to three year period subject to continuous service on each vesting date. The time-based RSUs for our non-employee directors generally vest over a one year period for existing members and 25% per year over a four-year period for new members subject to continuous service on each vesting date.
	During the six months ended June 30, 2014, we granted performance-based RSUs to executive personnel. These awards vest subject to certain performance objectives based on the Company’s annual revenue growth achieved during the specified performance period and certain long-term service conditions. The maximum number of RSUs that may vest is determined based on actual Company achievement with one-third of the performance-based RSUs vesting when the individual completes 12 months of continuous service and the balance vesting over a series of eight successive equal quarterly installments thereafter subject to continuous service on each vesting date. We recognize stock-based compensation expense for performance-based RSUs when we believe that it is probable that the performance objectives will be met.
	A summary of the nonvested RSU activity under the 2011 Plan is as follows:
		Number of Shares		Weighted Average
		(000’s)		Grant-Date Fair
				Value
	Nonvested at December 31, 2013	753		$	6.22

	Nonvested at June 30, 2014	1,669		$	5.99
	During the six months ended June 30, 2014, 539,773 shares of time-based RSUs vested. The Company issued 380,526 shares and the remaining shares were withheld to pay minimum statutory federal, state, and local employment payroll taxes on those vested awards.

Other parties’ interests in consolidated entities are reported as non-controlling interests. All intercompany balances and transactions have been eliminated in consolidation.
Business combinations	'
	Business combinations
	The results of businesses acquired in a business combination are included in the Company’s condensed consolidated financial statements from the date of the acquisition. Purchase accounting results in assets and liabilities of an acquired business being recorded at their estimated fair values on the acquisition date. Any excess consideration over the fair value of assets acquired and liabilities assumed is recognized as goodwill.
	The Company performs valuations of assets acquired and liabilities assumed for a business acquisition and allocates the purchase price to its respective net tangible and intangible assets. Determining the fair value of assets acquired and liabilities assumed requires management to use significant judgment and estimates including the selection of valuation methodologies, estimates of future revenues and cash flows, discount rates, royalty rates and selection of comparable companies. The Company engages the assistance of valuation specialists in concluding on fair values of assets and liabilities assumed in a business combination.
	Transaction costs associated with business combinations are expensed as incurred, and are included in general and administrative expenses in the condensed consolidated statements of operations. There were no significant transaction costs associated with business combinations for the three and six months ended June 30, 2014. Transaction costs associated with business combinations were $34 and $192 for the three and six months ended June 30, 2013, respectively.

Marketable securities	'
	Marketable securities
	Our marketable securities consist of available-for-sale securities with original maturities exceeding three months. In accordance with FASB ASC 320, Investments—Debt and Equity Securities, we have classified securities, which have readily determinable fair values and are highly liquid, as short-term because such securities are expected to be realized within a one-year period. At June 30, 2014 and December 31, 2013, we had $29,909 and $32,962, respectively, in marketable securities.
	Marketable securities are reported at fair value with the related unrealized gains and losses reported as other comprehensive income (loss) until realized or until a determination is made that an other-than-temporary decline in market value has occurred. No significant unrealized gains and losses have been reported during the periods presented. Factors considered by us in assessing whether an other-than-temporary impairment has occurred include the nature of the investment, whether the decline in fair value is attributable to specific adverse conditions affecting the investment, the financial condition of the investee, the severity and the duration of the impairment and whether we have the ability to hold the investment to maturity. When it is determined that an other-than-temporary impairment has occurred, the investment is written down to its market value at the end of the period in which it is determined that an other-than-temporary decline has occurred. The cost of marketable securities sold is based upon the specific identification method. Any realized gains or losses on the sale of investments are reflected as a component of interest and other (expense) income, net.
	For the six months ended June 30, 2014, we had no significant realized or unrealized gains or losses from investments in marketable securities classified as available-for-sale.
Revenue recognition	'
	Revenue recognition
	We generate revenue from several sources including: (i) platform service arrangements with wholesale customers that provide software licensing, network access, and professional services fees, (ii) wholesale customers that are telecom operators under long-term contracts for access to our DAS at our managed and operated locations, (iii) retail customers under subscription plans for month-to-month network access that automatically renew, and retail single-use access from sales of hourly, daily or other single-use access plans, and (iv) display advertisements and sponsorships on our walled garden sign-in pages. Software licensed by our wholesale platform services customers can only be used during the term of the service arrangements and has no utility to them upon termination of the service arrangement.
	We recognize revenue when an arrangement exists, services have been rendered, fees are fixed or determinable, no significant obligations remain related to the earned fees and collection of the related receivable is reasonably assured.
	Services provided to wholesale partners under platform service arrangements generally contain several elements including: (i) a term license to use our software to access our Wi-Fi network, (ii) access fees for network usage, and (iii) professional services for software integration and customization and to maintain the Wi-Fi service. The term license, monthly minimum network access fees and professional services are billed on a monthly basis based upon predetermined fixed rates. Once the term license for integration and customization are delivered, the fees from the arrangement are recognized ratably over the remaining term of the platform service arrangement. The initial term of platform service license agreements is generally between one to five years and the agreements generally contain renewal clauses. Revenue for network access fees in excess of the monthly minimum amounts is recognized when earned. All elements within existing platform service arrangements are generally delivered and earned concurrently throughout the term of the respective service arrangement.
	Revenue generated from access to our DAS networks consists of build-out fees and recurring access fees under certain long-term contracts with telecom operators. Build-out fees paid upfront are generally deferred and recognized ratably over the term of the estimated customer relationship period, once the build-out is complete. Minimum monthly access fees for usage of the DAS networks are non-cancellable and generally escalate on an annual basis. These minimum monthly access fees are recognized ratably over the term of the telecom operator agreement. The initial term of our contracts with telecom operators and wholesale partners generally range from three to fifteen years and the agreements generally contain renewal clauses. Revenue from network access fees in excess of the monthly minimums is recognized when earned.
	In instances where the minimum monthly network access fees escalate over the term of the wholesale service arrangement, an unbilled receivable is recognized when performance is within our control and when we have reasonable assurance that the unbilled receivable balance will be collected.
	We adopted the provisions of Accounting Standards Update (“ASU”) 2009-13, Revenue Recognition (Topic 605)—Multiple-Deliverable Revenue Arrangements (“ASU 2009-13”), on a prospective basis on January 1, 2011. For multiple-deliverable arrangements entered into prior to January 1, 2011 that are accounted for under ASC 605-25, Revenue Recognition—Multiple- Deliverable Revenue Arrangements, we defer recognition of revenue for the full arrangement and recognize all revenue ratably over the wholesale service period for platform service arrangements and the term of the estimated customer relationship period for DAS arrangements, because we do not have evidence of fair value for the undelivered elements in the arrangement. For multiple-deliverable arrangements entered into or materially modified after January 1, 2011 that are accounted for under ASC 605-25, we evaluate whether or not separate units of accounting exist and then allocate the arrangement consideration to all units of accounting based on the relative selling price method using estimated selling prices because vendor specific objective evidence and third party evidence is not available. We recognize the revenue associated with the separate units of accounting upon completion of such services or ratably over the wholesale service period for platform service arrangements and the term of the estimated customer relationship period for DAS arrangements.
	Subscription fees from retail customers are paid monthly in advance and revenue is deferred for the portions of monthly recurring subscription fees collected in advance. We do not have a stated or published refund policy for our Wi-Fi service, although our customer service representatives will provide a refund on a case-by-case basis. These amounts are not significant and are recorded as contra-revenue in the period the refunds are made. Subscription fee revenue is recognized ratably over the subscription period. Revenue generated from retail single-use access is recognized when earned.
	Advertising revenue is generated from advertisements on our managed and operated or partner networks. In determining whether an arrangement exists, we ensure that a binding arrangement is in place, such as a standard insertion order or a fully executed customer-specific agreement. Obligations pursuant to our advertising revenue arrangements typically include a minimum number of units or the satisfaction of certain performance criteria. Advertising and other revenue is recognized when the services are performed.

	Recent accounting pronouncements
	On May 28, 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which is intended to improve and converge the financial reporting requirements for revenue from contracts with customers between U.S. GAAP and International Accounting Standards. In accordance with this new standard, an entity would recognize revenue to depict the transfer of promised 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 standard establishes a five-step model and related application guidance, which will replace most existing revenue recognition guidance in U.S. GAAP. The standard will be effective for annual and interim periods in fiscal years beginning after December 15, 2016. Early adoption is not permitted. An entity may choose to adopt the new standard either retrospectively or through a cumulative effect adjustment as of the start of the first period for which it applies the new standard. We are currently evaluating the expected impact of this new standard on our reporting of revenue contracts in our consolidated financial statements.
