Nature of Operations	9 Months Ended
Nature of Operations	Dec. 31, 2015
Nature of Operations [Abstract]
Nature of Operations	1. Nature of Operations pdvWireless, Inc. (formerly known as Pacific DataVision, Inc., the “Company”) is a private wireless communications carrier and provider of mobile workforce communications and location based solutions that increase the productivity of its customers’ field-based workers and the efficiency of their dispatch and call center operations. The Company is deploying and operating private push-to-talk (“PTT”) networks in major markets throughout the United States, while at the same time pursuing a Federal Communications Commission (the “FCC”) regulatory process aimed at repurposing its spectrum to be able to deploy broadband technologies. The Company was originally incorporated in California in 1997, and reincorporated in Delaware in 2014. The Company maintains offices in Woodland Park, New Jersey, Reston, Virginia and San Diego, California. The Company’s initial focus is on deploying and operating dedicated, wide-area, two-way radio networks that offer PTT services to primarily dispatch-centric, small and medium-sized businesses. In June 2015, the Company commercially launched its PTT service in its first market located in the greater Houston, Texas metropolitan area. The Company currently has two additional markets fully launched, Dallas and Atlanta, and four more markets with sites in service (with additional market coverage sites to be launched), Philadelphia, Chicago, the greater New York area, and Washington/Baltimore. The Company offers its DispatchPlus™ communications solution, which combines Motorola Solutions, Inc.’s and its subsidiaries’ (collectively, “Motorola”) state-of-the-art digital technology architecture with pdvConnect™, the Company’s suite of mobile communications and workforce management applications. Built with the commercial dispatch user in mind, Motorola’s digital technology architecture allows the Company to provide highly reliable, instant and wide-area PTT communication solutions. Also developed by the Company 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 expects that its DispatchPlus business will become its principal near term operating business. However, the Company has not yet generated significant revenues from its DispatchPlus business. The Company primarily markets its DispatchPlus communication solutions indirectly through Motorola’s dealer network. The Company enters into contracts directly with end users of its DispatchPlus communication solutions, including those introduced to it through its indirect dealer network. Concurrently with launching its DispatchPlus business, the Company is pursuing initiatives to increase the efficiency and capacity of its spectrum licenses, including filing (together with the Enterprise Wireless Alliance) a Joint Petition for Rulemaking with the FCC proposing a realignment of a portion of the 900MHz spectrum from narrowband to broadband. If successful, the Company believes these initiatives could substantially enhance the capacity and capabilities of its spectrum. Historically, the Company has been engaged in the development and sale of its wireless communications applications, marketed primarily under the name pdvConnect. The Company primarily offers these applications indirectly to the end users of two Tier I wireless communications carriers in the United States and, until July 2015, one international wireless communications carrier under licensing agreements between the Company and these carriers. The Company also offers these applications directly to end users. In May 2015, the Company completed a registered follow-on public offering of common stock that resulted in the sale of 1,725,000 shares at a purchase price of $40.00 per share, which included 225,000 shares sold pursuant to the underwriters’ exercise of their over-allotment option. Net proceeds were approximately $64.8 million after deducting underwriting discounts and commissions and offering expenses.

Summary of Significant Accounting Policies	9 Months Ended
Summary of Significant Accounting Policies	Dec. 31, 2015
Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Basis of Presentation and Use of Estimates The consolidated financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”), which require 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 revisions are reflected in the financial statements in the applicable period, accordingly, actual results could differ from those estimates. The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries, including PDV Spectrum Holding Company, LLC formed in April 2014. All significant intercompany accounts and transactions have been eliminated in consolidation. The accompanying consolidated financial statements as of December 31, 2015 and for the three and nine month periods ended December 31, 2015 and 2014 are unaudited. These unaudited financial statements have been prepared in accordance with US GAAP for interim financial information and are presented in accordance with the requirements of Regulation S-X promulgated by the Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all the information and footnotes required by US GAAP for complete financial statements. Certain information and disclosures normally included in financial statements prepared in accordance with US GAAP have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures included herein are adequate to make the information presented not misleading and all adjustments considered necessary for a fair presentation have been included. In the opinion of management, the Company’s results for the three and nine months ended December 31, 2015 are not necessarily indicative of the results to be expected for the full year or any future financial period. Reclassifications Certain prior year amounts have been reclassified to conform to the presentation of the corresponding amounts in the financial statements for the three and nine months ended December 31, 2015. 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 at the time of purchase are considered cash equivalents. Cash equivalents are stated at cost, which approximates the quoted market value and include amounts held in money market funds. Allowance for Doubtful Accounts 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 December 31, 2015 and March 31, 2015, management provided an allowance of $600 and $7,977, respectively, for certain slow paying accounts. Property and Equipment Property 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 property 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 provide the Company with 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 FCC. License renewals have occurred routinely and at nominal cost in the past. 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 Company has determined that the wireless licenses should be treated as an indefinite-lived intangible asset. The Company will evaluate the useful life determination for its wireless licenses each year to determine whether events and circumstances continue to support their treatment as an indefinite useful life asset. The licenses are tested for impairment on an aggregate basis, as the Company will be utilizing the wireless licenses on an integrated basis as part of developing its nationwide network. The Company performs the test of the fair values of the 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. 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. Revenue Recognition The Company recognizes revenue in the period that persuasive evidence of an arrangement exists, delivery of the product has occurred or services have been rendered, it is able to determine the amount of revenue and when the collection of such amount is considered probable. 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 Tier I domestic carrier partners. As a result, revenue is recorded at the gross amount billed to end-user customers for sales through these carrier partners. The Company recognized service revenue for its international carrier (which business relationship terminated in July 2015) on the net amount billed since it has determined that it is not the primary obligor. The Company also sells service and applications directly to end-users, which are billed and collected directly by the Company. In September 2014, Motorola paid the Company an upfront, fully-paid leasing fee of $7.5 million in order to lease a portion of the Company’s wireless spectrum licenses. The payment of the fee is accounted for as Deferred Revenue on the Company’s Consolidated Balance Sheets. 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 period in which the benefits of the leased property are expected to be depleted. The Company evaluates certain transactions for its DispatchPlus service offering to determine whether they should be viewed as a Multiple Element Arrangement provided in ASC Topic 605-25. Multiple deliverable arrangements are presumed to be bundled transactions, and the total consideration is measured and allocated to the separate transactions based on their relative selling price with certain limitations. The Company has determined that the rental of user devices in connection with service contracts for its DispatchPlus service are multiple deliverable arrangements. Cost of Revenue The Company’s cost of revenue relating to sales of its software applications through its wireless carrier partners 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, sales, marketing, billing and other ancillary services. With respect to its recently launched DispatchPlus service offering, the Company’s cost of revenue includes the costs of operating its dispatch network, and its cloud-based solutions and to a lesser degree, the costs associated with the sales of the relevant user devices. 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. In the event the participant’s employment by or engagement with (as a director or otherwise) the Company terminates before exercise of the options granted, the stock options granted to the participant shall immediately expire and all rights to purchase shares thereunder shall immediately cease and expire and be of no further force or effect, other than applicable exercise rights for vested shares that may extend past the termination date as provided for in the participant’s applicable option award agreement. Additionally, the Compensation Committee adopted an Executive Severance Plan (the “Severance Plan”) in February 2015, and the Company subsequently entered into Severance Plan Participation Agreements with its executive officers and certain key employees. In addition to providing participants with severance payments, the Severance Plan provides for accelerated vesting and extends the exercise period for outstanding equity awards if the Company terminates a participant’s service for reasons other than cause, death or disability or the participant terminates his or her service for good reason, whether before or after a change of control (each of such terms as defined in the Severance Plan). 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 the 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 the Company maintained a full valuation allowance for all net deferred tax assets. Recently Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606), ("ASU 2014-09") which supersedes current revenue recognition guidance, including most industry-specific guidance. ASU 2014-09 requires a company to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods and services, and also requires additional disclosures regarding the nature, amount, timing and uncertainty of revenue that is recognized. The guidance, as stated in ASU 2014-09, is effective for annual and interim periods beginning after December 15, 2016. In August 2015, the FASB issued ASU No. 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date," which defers the effective date by one year, with early adoption on the original effective date permitted. The Company is evaluating the impact the new guidance will have on its consolidated financial statements. In August 2014, FASB issued ASU 2014-15, Presentation of Financial Statements. This ASU requires management to assess an entity’s ability to continue as a going concern by incorporating and expanding upon certain principles that are currently in the U.S. auditing standards. Specifically, the ASU (1) provides a definition of the term substantial doubt, (2) requires an evaluation every reporting period including interim periods, (3) provides principles for considering the mitigating effect of management’s plans, (4) requires certain disclosures when substantial doubt is alleviated as a result of consideration of management’s plan, (5) requires an express statement and other disclosures when substantial doubt is not alleviated, and (6) requires an assessment for a period of one year after the date that the financial statements are issued (or available to be issued). This standard is effective for the fiscal years ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. The Company is currently evaluating the new guidance to determine the impact it will have on its consolidated financial statements. In January 2015, FASB issued ASU 2015-01, Extraordinary and Unusual Items, eliminating the concept of extraordinary items. The issuance is part of the FASB’s initiative to reduce complexity in accounting standards. Under the current guidance, an entity is required to separately classify, present and disclose events and transactions that meet the criteria for extraordinary classification. Under the new guidance, reporting entities will no longer be required to consider whether an underlying event or transaction is extraordinary, however, presentation and disclosure guidance for items that are unusual in nature or occur infrequently was retained and expanded to include items that are both unusual in nature and infrequently occurring. The amendments are effective for the Company’s fiscal year beginning April 1, 2016, although early adoption is permitted if applied from the beginning of a fiscal year. The Company does not expect the adoption of this guidance to have a material effect on its consolidated financial statements. In April 2015, FASB issued ASU No. 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 consolidated financial statements. In September 2015, FASB issued ASU 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments, which requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined, including the cumulative effect of the change in provisional amount as if the accounting had been completed at the acquisition date. The adjustments related to previous reporting periods since the acquisition date must be disclosed by income statement line item either on the face of the income statement or in the notes. The guidance is effective for fiscal years and interim reporting periods within those years beginning after December 15, 2015, with early application permitted for financial statements that have not been issued. The amendments are to be applied prospectively to adjustments that occur after the effective date. The amendments will be effective for the Company for the fiscal year beginning April 1, 2016 and will be applied, as necessary, to future business combinations. Management does not believe that any other recently issued, but not yet effective accounting pronouncements, if adopted, would have a material effect on the accompanying Consolidated Financial Statements. 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 three and nine months ended December 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 1,100,000 and 1,000,000 at December 31, 2015 and March 31, 2015, respectively, and have not been included in the diluted weighted average shares outstanding, as their effects are anti-dilutive. Subsequent Events Evaluation by Management Management has evaluated subsequent events for disclosure and/or recognition in the financial statements through the date that these financial statements were issued.

Intangible Assets

4.Intangible Assets

Wireless licenses are considered indefinite-lived intangible assets. Indefinite-lived intangible assets are not subject to amortization but instead are tested for impairment annually, or more frequently if an event indicates that the asset might be impaired. The Company believes that no impairment indicators existed as of December 31, 2015 that would require it to perform impairment testing.

During the nine months ended December 31, 2015, the Company entered into agreements with several third parties in multiple U.S. markets to acquire wireless licenses for cash consideration, as well as a promissory note (see Note 6), upon FCC approval. Also during the period, the Company entered into an agreement with a third party to exchange wireless licenses. The first exchange occurred in June 2015, when the Company transferred wireless licenses to the counterparty. The second exchange is anticipated to occur by the end of Fiscal 2016, when the Company will receive wireless licenses from the counterparty. The second exchange is accounted for as an Other asset in the Company’s Consolidated Balance Sheets as of December 31, 2015.

The term of the note is through March 15, 2018 and bears a fixed rate of interest, of 0.55% per annum, which is based on the Short Term Applicable Federal Rate on the closing date. As of December 31, 2015, the Company had outstanding borrowings of the full amount of the promissory note, of which $297,203 is in Current liabilities on the Company’s Consolidated Balance Sheets.

Income Taxes [Abstract]
Income Taxes	7. Income Taxes The Company had federal and state net operating loss carryforwards of approximately $28.7 million at March 31, 2015, which expire in varying amounts from 2021 through 2035. The Company has deferred tax assets of approximately $14.7 million relating to these net operating loss carryforwards and stock compensation plans at March 31, 2015. Federal net operating loss carryforwards are subject to limitations as a result of a change in ownership. 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 primarily attributable to a full valuation allowance placed upon the deferred tax asset. The Company recognizes the effect of tax positions only when they are more likely than not to be sustained. The Company’s management has determined that it 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 2013.

8. Stock Acquisition Rights, Stock Options and Warrants

The Company established the pdvWireless, Inc. 2014 Stock Plan (the “2014 Stock Plan”) to attract, retain and reward individuals who contribute to the growth of the Company. This 2014 Stock Plan superseded previously established stock plans although under such previous plans, 52,567 stock options were vested and outstanding as of December 31, 2015.

As of December 31, 2015, the Company’s Board of Directors had authorized and reserved 1,823,651 shares of common stock for issuance under its 2014 Stock Plan. The number of shares authorized and reserved for issuance under the 2014 Stock Plan increased on January 1, 2016 by 714,583 shares of common stock, for an aggregate of 2,538,234 shares authorized and reserved under the 2014 Stock Plan. The shares authorized and reserved for issuance under the 2014 Stock Plan will continue to 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 April 1, 2015 through December 31, 2015, the Company awarded certain employees of the Company 194,000 options to purchase shares of common stock with a weighted average exercise price of $37.16 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.

Restricted Stock

During the nine months ended December 31, 2015, the Company awarded 70,978 restricted stock awards and units at a weighted average grant price of $27.11.

These restricted stock units were issued under the Company’s 2010 Stock Plan and the 2014 Stock Plan and the restricted stock awards were issued under the 2014 Stock Plan. The Company recognizes compensation expense for restricted stock 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. At December 31, 2015, there was $1.8 million of unvested compensation expense of the restricted stock, which is expected to be recognized over a weighted average period of 3.6 years.

The Black-Scholes option model requires weighted average assumptions to be used for calculation of the Company’s stock compensation expense. The assumptions used during the three and nine months ended December 31, 2015 were: the expected life of the awards was 5 years, the risk-free interest rate ranged from 1.29% to 1.71%, the expected volatility was 40.0%, and the expected dividend yield was 0.0%. There was a 2% forfeiture rate used for the calculation.

Stock compensation expense was $1,132,119 and $3,587,730 for the three and nine months ended December 31, 2015, respectively, of which $72,160 related to restricted stock awards and units. For the three and nine months ended December 31, 2014, stock compensation expense was $1,404,202 and $4,680,802. Included in the nine months ended December 31, 2014, the Company recognized $1,676,080 related to restricted stock units issued. Stock compensation expense is included as part of General and administrative expense in the accompanying Consolidated Statements of Operations.

The weighted average fair value for each stock option award granted during the nine months ended December 31, 2015, was $13.80 per share. As of December 31, 2015, there was approximately $5.8 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 2.82 years. The intrinsic value of the options outstanding and exercisable at December 31, 2015 was approximately $9.8 million and $3.1 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 of these Class B Units 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 consolidated financial statements.

Leasing Obligations

The Company is obligated under certain lease agreements for office space. These leases expire on June 30, 2016, January 7, 2019, June 30, 2019, and May 31, 2020, respectively. Rent expense amounted to $182,835 and $405,187 in the three and nine months ended December 31, 2015, of which $82,137 and $142,483 was classified in Cost of revenue in the Consolidated Statements of Operations for the three and nine months ended December 31, 2015, respectively. The remainder of the rent expense, $100,698 and $262,704, was classified as Operating expense in the Consolidated Statements of Operations for the same periods, respectively. For the three and nine months ended December 31, 2014, total rent expense of $21,790 and $83,087, respectively, was classified in Operating expenses in the Consolidated Statements of Operations.

The Company entered into multiple lease agreements for tower space related to its new DispatchPlus business and deployment of the related dedicated, wide-area, two-way dispatch radio network. The lease expiration dates range from February 28, 2020 to December 31, 2025.

The straight-line method is used to recognize minimum rent expense under leases that provide for varying rents over their term. The effect of applying the straight-line basis resulted in an increase in rental expense of approximately $42,000 and $190,000 in the three and nine months ended December 31, 2015, respectively. The impact to the three and nine months ended December 31, 2014 was a decrease in rental expense of approximately $9,600 and $18,200, respectively. At December 31, 2015, Accumulated deferred rent payable amounted to approximately $321,000 and is included as part of Accounts payable and accrued expenses in the accompanying December 31, 2015 Consolidated Balance Sheets.

Aggregate rentals, under non-cancelable leases for office and tower space (exclusive of real estate taxes, utilities, maintenance and other costs borne by the Company) for the remaining terms of the leases are as follows:

Summary of Significant Accounting Policies (Policies)	Dec. 31, 2015
Summary of Significant Accounting Policies [Abstract]
Basis of Presentation and Use of Estimates	Basis of Presentation and Use of Estimates The consolidated financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”), which require 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 revisions are reflected in the financial statements in the applicable period, accordingly, actual results could differ from those estimates. The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries, including PDV Spectrum Holding Company, LLC formed in April 2014. All significant intercompany accounts and transactions have been eliminated in consolidation. The accompanying consolidated financial statements as of December 31, 2015 and for the three and nine month periods ended December 31, 2015 and 2014 are unaudited. These unaudited financial statements have been prepared in accordance with US GAAP for interim financial information and are presented in accordance with the requirements of Regulation S-X promulgated by the Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all the information and footnotes required by US GAAP for complete financial statements. Certain information and disclosures normally included in financial statements prepared in accordance with US GAAP have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures included herein are adequate to make the information presented not misleading and all adjustments considered necessary for a fair presentation have been included. In the opinion of management, the Company’s results for the three and nine months ended December 31, 2015 are not necessarily indicative of the results to be expected for the full year or any future financial period.
Reclassifications	Reclassifications Certain prior year amounts have been reclassified to conform to the presentation of the corresponding amounts in the financial statements for the three and nine months ended December 31, 2015. 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 at the time of purchase are considered cash equivalents. Cash equivalents are stated at cost, which approximates the quoted market value and include amounts held in money market funds.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts 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 December 31, 2015 and March 31, 2015, management provided an allowance of $600 and $7,977, respectively, for certain slow paying accounts.
Property and Equipment	Property and Equipment Property 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 property 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 provide the Company with 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 FCC. License renewals have occurred routinely and at nominal cost in the past. 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 Company has determined that the wireless licenses should be treated as an indefinite-lived intangible asset. The Company will evaluate the useful life determination for its wireless licenses each year to determine whether events and circumstances continue to support their treatment as an indefinite useful life asset. The licenses are tested for impairment on an aggregate basis, as the Company will be utilizing the wireless licenses on an integrated basis as part of developing its nationwide network. The Company performs the test of the fair values of the 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.
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.
Revenue Recognition	Revenue Recognition The Company recognizes revenue in the period that persuasive evidence of an arrangement exists, delivery of the product has occurred or services have been rendered, it is able to determine the amount of revenue and when the collection of such amount is considered probable. 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 Tier I domestic carrier partners. As a result, revenue is recorded at the gross amount billed to end-user customers for sales through these carrier partners. The Company recognized service revenue for its international carrier (which business relationship terminated in July 2015) on the net amount billed since it has determined that it is not the primary obligor. The Company also sells service and applications directly to end-users, which are billed and collected directly by the Company. In September 2014, Motorola paid the Company an upfront, fully-paid leasing fee of $7.5 million in order to lease a portion of the Company’s wireless spectrum licenses. The payment of the fee is accounted for as Deferred Revenue on the Company’s Consolidated Balance Sheets. 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 period in which the benefits of the leased property are expected to be depleted. The Company evaluates certain transactions for its DispatchPlus service offering to determine whether they should be viewed as a Multiple Element Arrangement provided in ASC Topic 605-25. Multiple deliverable arrangements are presumed to be bundled transactions, and the total consideration is measured and allocated to the separate transactions based on their relative selling price with certain limitations. The Company has determined that the rental of user devices in connection with service contracts for its DispatchPlus service are multiple deliverable arrangements.
Cost of Revenue	Cost of Revenue The Company’s cost of revenue relating to sales of its software applications through its wireless carrier partners 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, sales, marketing, billing and other ancillary services. With respect to its recently launched DispatchPlus service offering, the Company’s cost of revenue includes the costs of operating its dispatch network, and its cloud-based solutions and to a lesser degree, the costs associated with the sales of the relevant user devices.
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. In the event the participant’s employment by or engagement with (as a director or otherwise) the Company terminates before exercise of the options granted, the stock options granted to the participant shall immediately expire and all rights to purchase shares thereunder shall immediately cease and expire and be of no further force or effect, other than applicable exercise rights for vested shares that may extend past the termination date as provided for in the participant’s applicable option award agreement. Additionally, the Compensation Committee adopted an Executive Severance Plan (the “Severance Plan”) in February 2015, and the Company subsequently entered into Severance Plan Participation Agreements with its executive officers and certain key employees. In addition to providing participants with severance payments, the Severance Plan provides for accelerated vesting and extends the exercise period for outstanding equity awards if the Company terminates a participant’s service for reasons other than cause, death or disability or the participant terminates his or her service for good reason, whether before or after a change of control (each of such terms as defined in the Severance Plan). 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 the 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 the Company maintained a full valuation allowance for all net deferred tax assets.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606), ("ASU 2014-09") which supersedes current revenue recognition guidance, including most industry-specific guidance. ASU 2014-09 requires a company to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods and services, and also requires additional disclosures regarding the nature, amount, timing and uncertainty of revenue that is recognized. The guidance, as stated in ASU 2014-09, is effective for annual and interim periods beginning after December 15, 2016. In August 2015, the FASB issued ASU No. 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date," which defers the effective date by one year, with early adoption on the original effective date permitted. The Company is evaluating the impact the new guidance will have on its consolidated financial statements. In August 2014, FASB issued ASU 2014-15, Presentation of Financial Statements. This ASU requires management to assess an entity’s ability to continue as a going concern by incorporating and expanding upon certain principles that are currently in the U.S. auditing standards. Specifically, the ASU (1) provides a definition of the term substantial doubt, (2) requires an evaluation every reporting period including interim periods, (3) provides principles for considering the mitigating effect of management’s plans, (4) requires certain disclosures when substantial doubt is alleviated as a result of consideration of management’s plan, (5) requires an express statement and other disclosures when substantial doubt is not alleviated, and (6) requires an assessment for a period of one year after the date that the financial statements are issued (or available to be issued). This standard is effective for the fiscal years ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. The Company is currently evaluating the new guidance to determine the impact it will have on its consolidated financial statements. In January 2015, FASB issued ASU 2015-01, Extraordinary and Unusual Items, eliminating the concept of extraordinary items. The issuance is part of the FASB’s initiative to reduce complexity in accounting standards. Under the current guidance, an entity is required to separately classify, present and disclose events and transactions that meet the criteria for extraordinary classification. Under the new guidance, reporting entities will no longer be required to consider whether an underlying event or transaction is extraordinary, however, presentation and disclosure guidance for items that are unusual in nature or occur infrequently was retained and expanded to include items that are both unusual in nature and infrequently occurring. The amendments are effective for the Company’s fiscal year beginning April 1, 2016, although early adoption is permitted if applied from the beginning of a fiscal year. The Company does not expect the adoption of this guidance to have a material effect on its consolidated financial statements. In April 2015, FASB issued ASU No. 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 consolidated financial statements. In September 2015, FASB issued ASU 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments, which requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined, including the cumulative effect of the change in provisional amount as if the accounting had been completed at the acquisition date. The adjustments related to previous reporting periods since the acquisition date must be disclosed by income statement line item either on the face of the income statement or in the notes. The guidance is effective for fiscal years and interim reporting periods within those years beginning after December 15, 2015, with early application permitted for financial statements that have not been issued. The amendments are to be applied prospectively to adjustments that occur after the effective date. The amendments will be effective for the Company for the fiscal year beginning April 1, 2016 and will be applied, as necessary, to future business combinations. Management does not believe that any other recently issued, but not yet effective accounting pronouncements, if adopted, would have a material effect on the accompanying Consolidated Financial Statements.
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 three and nine months ended December 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 1,100,000 and 1,000,000 at December 31, 2015 and March 31, 2015, respectively, and have not been included in the diluted weighted average shares outstanding, as their effects are anti-dilutive.
Subsequent Events Evaluation by Management	Subsequent Events Evaluation by Management Management has evaluated subsequent events for disclosure and/or recognition in the financial statements through the date that these financial statements were issued.

- Definition

Tabular disclosure of warrants or rights issued. Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.
