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 communication and location based solutions focused on increasing the productivity of its customers’ field-based workers and the efficiency of their dispatch and call center operations. The Company commenced launching private push-to-talk (“PTT”) networks in major markets throughout the United States. Its proprietary and industry-validated suite of mobile communications and workforce management applications improve team communication and field documentation across a wide array of industries, including transportation, distribution, construction, hospitality, waste management and field services. At the same time, the Company is pursuing a number of broadband spectrum opportunities and initiatives, including but not limited to, a Federal Communications Commission (“FCC”) regulatory process aimed at the realignment of its spectrum to be able to deploy broadband technologies to enterprises. The Company was originally incorporated in California in 1997, and reincorporated in Delaware in 2014 . In November 2015, the Company changed its name from Pacific DataVision, Inc. to pdvWireless, Inc. The Co mpany maintains offices in Woodland Park, New Jersey, Reston, Virg inia and San Diego, California. It also maintains a sales office in West Conshohocken, Pennsylvania. The Company is currently deploying and operating dedicated, wide-area, two-way radio networks that offer PTT communications services to primarily dispatch-centric, small and medium-sized businesses. In June 2015, the Company commercially launched its PTT service, which it markets as DispatchPlus ™ , in the greater, Houston, Texas metropolitan area. The Company commenced service in six additional major metropolitan markets during fiscal 2016, including: Dallas, Atlanta, Philadelphia, Chicago, the greater New York area and Baltimore/Washington. The Company offers its DispatchPlus communications solutions, which combines pdvConnect ™ , its proprietary suite of mobile communication and workforce management applications with state-of-the-art digital network architecture and mobile devices supplied by Motorola Solutions, Inc. and its subsidiaries (“Motorola”). Developed for dispatch-centric businesses, pdvConnect is an easy to use and efficient mobile communication and workforce management solutions that enables businesses to locate and communicate with their field workers and improve the documentation of work events and job status. Also built with the commercial dispatch user in mind, Motorola’s digital network architecture allows the Company to provide highly reliable, instant and wide-area PTT communication services to its customers. The Company expects that its DispatchPlus business will become its principal near term operating business. However, the Company has not yet generated significant revenues fro m its DispatchPlus business. The Company primarily markets its DispatchPlus service to customers indirectly through third-party dealers selected from Motorola’s nationwide dealer network and other select wireless dealers. The Company supports its indirect sales representatives by providing them with training, marketing and advertising support from its internal sales and marketing team. 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 900 MHz spectrum from narrowband to broadband. The Company has responded to all requests for information from the FCC and other interested parties, and it is currently awaiting FCC action. The FCC’s action may take a number of forms ranging from: a Notice of Proposed Rulemaking, to a Notice of Inquiry, to a dismissal of the Joint Petition without further action . To its knowledge, the FCC has not reached a decision on the Joint Petition. The Company currently believes that the most likely outcome is that the FCC will adopt a Notice of Inquiry as the next step in the process. The Company has no information, however, on the content or scope of a potential Notice of Inquiry. A Notice of Inquiry is a vehicle for the FCC to gather additional information for the record. If the FCC elects to adopt a Notice of Inquiry, it could request additional information and input on the optimal use of the 900 MHz band generally. A Notice of Inquiry could also request information on the specific issues and proposed solutions raised by us and other commentators in the proceeding. The adoption of a Notice of Inquiry does not mean that the FCC has denied its Joint Petition, or that the Joint Petition will not ultimately result in a Notice of Proposed Rulemaking. The Company continues to believe in the merits of its proposal, and that the Joint Petition is consistent with the FCC’s past practices and policies . Nevertheless , obtaining a favorable result from the FCC may take a significant amount of time and resources . Moreover, there is no assurance that the FCC will adopt the proposed rules, or ultimately approve the Company’s Joint Petition . In addition to this regulatory action, the Company is also pursuing a number of broadband and additional spectrum and wireless service opportunities, including acquiring additional spectrum to support its realignment efforts and the deployment of a future broadband network, attempting to build consensus with incumbents in the 900 MHz band, developing a strategic plan for its future deployment of a broadband or other wireless services in the 900 MHz band, and evaluating whether existing technologies and equipment can be used to support its spectrum initiatives and opportunities. In addition to its opportunities in the 900 MHz band, the Company is pursuing additional spectrum and related wireless service opportunities. The potential opportunities it has been exploring include several surrounding the First Responder Network Authority (“FirstNet”), which involves government plans and a related process to provide a substantial amount of funding for the build-out and operation of a dedicated Nationwide Public Safety Broadband Network (“NPSBN”) that also may be used, on a non-priority, excess capacity basis, to meet the wireless service needs of a variety of commercial customers. There is no assurance, however, that the Company will be successful in its pursuit of spectrum opportunities related to FirstNet or any other spectrum opportunities that it identifies and attempts to pursue. Prior to acquiring its 900 MHz spectrum, the Company wa s 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. During the fiscal year ended March 31, 2015, the Company: Entered into an Asset Purchase Agreement with certain wholly-owned subsidiaries of Sprint Corporation (the “Sprint APA”) to purchase nationwide spectrum in the 900 MHz band for a total of $100.0 million, with $90.0 million paid in cash from the proceeds of the private placement the Company completed in June 2014 (the “June 2014 Private Placement”) (see below) and $10.0 million paid in 500,000 shares of common stock (at a price equal to $20.00 per share). Completed the June 2014 Private Placement, on June 10, 2014, in which the Company sold 10,925,000 shares of common stock at a purchase price of $20.00 per share. The net proceeds from the June 2014 Private Placement after deducting expenses including professional fees and the payment of initial placement fees, were approximately $202 million. Approximately 96% of the net proceeds, or approximately $196 million (net of any initial purchaser’s /placement agent’s discount and placement fees), were held in trust until the closing of the Sprint APA. The parties closed the Sprint APA in September 2014 upon receipt of the necessary approvals from the FCC. In September 2014, the Company used a portion of the proceeds from the sale of common stock to: · Pay the outstanding working capital line for $1,470,000 (see Note 9) and $351,073 in accrued interest with 65,000 shares of common stock and $521,073 in cash; · Pay the promissory note of $540,000 (see Note 9) and $272,842 in accrued interest in cash; · Pay the outstanding Series AA convertible promissory notes owed to certain employees for $423,852 and $283,856 (see Note 9) in accrued interest in cash; · Pay $367,695 owed to certain employees for deferred compensation in cash (see Note 8); and · Convert the Redeemable Notes (as defined in Note 9 below) of $1,016,956 into 77,733 shares of common stock based on 140% of the outstanding principal and accrued interest. Follo wing the closing of the Sprint A PA, the Company closed agreements with Motorola on September 15, 2014, under which Motorola invested $10.0 million to purchase 500,000 Class B Units of the company’s subsidiary, PDV Spectrum Holding Company, LLC ( at a price equal to $20.00 per unit) and leased some of the Spectrum Assets for a prepaid price of $7.5 million. In connection with the June 2014 Private Placement, the Company completed a number of actions, including: · The reincorporation of the Company from California to Delaware; · The conversion of all outstanding shares of the Company’s Series AA Preferred Stock into 748,722 shares of the Company’s common stock, the exchange of 661,581 outstanding warrants to purchase shares of Series AA Preferred Stock into 29,809 shares of common stock, and the conversion of the remaining options and warrants to purchase shares of the Company’s Series AA Preferred Stock into options or warrants to purchase shares of common stock and the conversion of restricted stock units for shares of its Series AA Preferred Stock into restricted stock units for shares of common stock; · The amendment of outstanding Redeemable Notes, in the aggregate principal of $1,016,956 , to provide that the Redeemable Notes would automatically be converted at the closing of the Sprint APA into that number of shares of common stock equal to the sum of 140% of the principal plus the outstanding interest on such Redeemable Notes through the conversion divided by $20.00 per share; · A 33.11451201-for-1 reverse stock split of all outstanding common stock, which was effected immediately prior to the completion of the June 2014 Private Placement. All share and per share data reported and disclosed in the accompanying financial statements have been retroactively adjusted to give effect to the reverse stock split; · Entered into an agreement with Motorola on May 12, 2014, under which Motorola agreed to provide the Company with their digital radio technology and handsets that it intends to deploy as part of the nationwide network; and · An increase in the authorized shares of common stock to 100,000,000 shares and preferred stock to 10,000,000 shares, and a change in the par value of the Company’s common stock from no par value to $0.0001 per share. The preferred stock has first priority on liquidation preference over the common stock. In addition, in connection with the June 2014 Private Placement and the recapitalization of the Company, the Company issued 1,390,957 stock options to purchase the Company’s common stock and 83,804 restricted units of its common stock. On January 26, 2015, the Securities and Exchange Commission (“SEC”) declared effective the Company’s registration statement on Form S-1 relating to the resale of 11,925,000 shares of common stock acquired by the selling stockholders in the June 2014 Private Placement as well as the 500,000 shares of common stock issuable upon the conversion of the Class B Units of the Company’s subsidiary, PDV Spectrum Holding Company, LLC issued to Motorola. The Company received no proceeds from any sales by the selling stockholders. On February 3, 2015, shares of the Company’s common stock were listed for trading on The NASDAQ Capital Market under the symbol “PDVW”. Also, on January 26, 2015, the Company completed a private placement with a secondary closing on January 30, 2015. The Company sold 57,470 shares of common stock at a purchase price of $25.00 per share to certain accredited investors in reliance on exemptions from registration under the Securities Act. The net proceeds from the January 2015 Private Placement were approximately $1,386,000 . The purpose of this private placement was to secure additional round lot stockholders to enable the C ompany to satisfy the initial listing standards of The NASDAQ Capital Market. The Company used the net proceeds for general corporate purposes, including working capital. 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 [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, asset retirement obligations, the carrying amount of long-lived assets under construction in process, valuation allowance on the Company’s deferred tax assets, and recoverability of intangible assets. The Company is also required to make certain estimates with regard to the valuation of awards and forfeiture rates for its share-based award programs. Estimates and assumptions are reviewed periodically and the effects of revision are reflected in the financial statements in the period they are deemed to be necessary. Accordingly actual results could differ from those estimates. The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries, including PDV Spectrum Holding Company, LLC formed in April 2014. All significant intercompany accounts and transactions have been eliminated in consolidation. Reclassifications Certain prior year amounts have been reclassified to conform to the financial statements for the year ended March 31, 2016 financial statement presentation. These reclassifications had no effect on previously reported results of operations, cash flows, assets, liabilities or equity for the years presented. Cash and Cash Equivalents All highly liquid investments with maturities of three months or less of the time of purchase are considered cash equivalents. Cash equivalents are stated at cost, which approximates quoted market value and include amounts held in money market funds. Allowance for 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 March 31, 2016 and March 31, 2015, management provided an allowance of $2,633 and $7,977 , respectively, for certain slow paying accounts. Inventory Inventories, which consist of vehicle-mounted devices and handsets, are valued at the lower of cost or market, with market being defined as replacement value using the First In, First Out method. Provisions are made periodically to reduce any excess, obsolete or slow moving inventory to its net realizable value. Property and Equipment Property and equipment is stated at cost. Depreciation is computed using the straight-line method over the shorter of the estimated useful lives of the assets or the applicable lease term. 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, assets being constructed that are not ready to be placed into service, and assets that are not currently in 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. Accounting for Asset Retirement Obligations An asset retirement obligation is evaluated and recorded as appropriate on assets for which the Company has a legal obligation to retire. The Company records a liability for an asset retirement obligation and the associated asset retirement cost at the time the underlying asset is acquired and put into service. Subsequent to the initial measurement of the asset retirement obligation, the obligation is adjusted at the end of each period to reflect the passage of time and changes in the estimated future cash flows underlying the obligation, if any. The Company enters into long-term leasing arrangements primarily for tower site location s. The Company constructs assets at these locations and, in accordance with the terms of many of these agreements, the Company is obligated to restore the premises to their original condition at the conclusion of the agreements, generally at the demand of the other party to these agreements. The Company recognizes the fair value of a liability for an asset retirement obligation and capitalizes that cost as part of the cost basis of the related asset, depreciating it over the useful life of the related asset . As of March 31, 2016, the Company had an asset retirement obligation of $ 203,546 . Intangible Assets Intangible assets are wireless licenses that will be used to provide the exclusive right to utilize designated radio frequency spectrum to provide wireless communication services. While licenses are issued for only a fixed time, generally ten years, such licenses are subject to renewal by the FCC. License renewals have occurred routinely and at nominal cost. There are currently no legal, regulatory, contractual, competitive, economic or other factors that limit the useful life of the company’s wireless licenses. As a result, the wireless licenses are treated as an indefinite-lived intangible asset. The Company evaluates the useful life determination for wireless licenses each year to determine whether events and circumstances continue to support an indefinite useful life. The licenses are tested for impairment on an aggregate basis, as the Company will be utilizing the wireless licenses on an integrated basis as a part of developing its nationwide network. The Company considers estimates of valuation methods to perform the test of the fair values of wireless licenses annually including market based and discounted cash flow approaches. Patent Costs Costs to acquire a patent on certain aspects of the Company’s technology have been capitalized. These amounts are amortized, subject to periodic evaluation for impairment, over statutory lives following award of the patent. Gross patent costs are $570,994 at March 31, 2016 and $558,696 at March 31, 2015 and the associated accumulated amortization amounted to $348,634 and $337,914 , respectively. Amortization expense was $10,720 , $34,609 , and $42,830 for the years ended March 31, 2016 , 2015 and 2014 , respectively. The amortization expense is estimated to aggregate $15,000 per year over the next five year period. Renewal costs are expensed when incurred. Long-Lived Asset Impairment The Company evaluates long-lived assets, other than intangible assets with indefinite lives, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. Asset groups are determined at the lowest level for which identifiable cash flows are largely independent of cash flows of other groups of assets and liabilities. When the carrying amount of a long-lived asset group is not recoverable and exceeds its fair value, an impairment loss is recognized equal to the excess of the asset group’s carrying value over the estimated fair value. Fair Value of Financial Instruments Financial instruments, including cash and cash equivalents, accounts receivable, accounts payable, and accrued expenses are carried at cost, which management believes approximates fair value because of the short term maturity of these instruments. Revenue Recognition The Company recognizes revenue in the period 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 d eferred r evenue 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. Judgment is required to properly identify the accounting units of the multiple deliverable transactions and to determine the manner in which revenue should be allocated among the units of accounting. 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 relative selling price for each deliverable is determined using vendor-specific objective evidence (“V SOE”) of selling price or third party evidence of selling price if VSOE does not exist. If neither VSOE nor third party evidence of selling price exist, the Company uses its best estimate of the selling price for the deliverable. The Company has determined that the rental of user devices in connection with service contracts for its DispatchPlus service a re 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. Shipping and Handling Costs Costs associated to shipping and handling of two-way radios to dealers or end-user customers are recognized as incurred and included in cost of revenue in the Consolidated Statements of Operations. Indirect Sales Commissions Cash consideration given to a dealer is presumed to be a reduction of revenue unless the Company receives, or will receive, an identifiable benefit in exchange for the consideration, and the fair value of such benefit can be reasonably estimated, in which case the consideration will be recorded as a selling expense. The Company compensates its indirect sales representatives with an upfront commission and residual fees based on a customer’s continued use of its DispatchPlus s ervice . When a commission is earned solely due to the selling activity relating to the Company’s DispatchPlus service , the cost is recorded as a selling expense. The Company reviews and records the e stimated incentives payable to the indirect sales representatives as accrued expense on a monthly basis. Product Development Costs The Company charges all product and development costs to expense as incurred. Types of expense incurred in product and development include employee compensation, consulting, travel, facility costs and equipment and technology costs. Advertising and Promotional Expense The Company expenses advertising and promotional costs as incurred. Cooperative advertising reimbursements from vendors are recorded net of advertising and promotional expense in the period in which the related advertising and promotional expense is incurred. Advertising and promotional expense was $161,257 for the year ended March 31, 2016. No advertising costs were incurred in 2015 and 2014. Stock Compensation The Company accounts for restricted stock, restricted stock units, performance units, and 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 Consolidated 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. The fair value of restricted stock , restricted stock units and performance units are measured based upon the quoted closing market price for the stock on the date of grant. The compensation cost for the restricted stock and restricted stock units is recognized on a straight-line basis over the vesting period. The compensation cost for the performance units is recognized when the performance criteria are expected to be complete. No tax benefits were attributed to the share-based compensation expense because the Company maintained a full valuation allowance for all net d eferred tax assets. Income Taxes The Company follows the liability method of accounting for income taxes. Under this method, taxes consist of taxes currently payable plus those deferred due to temporary differences between the financial statement carrying amounts and the tax bases of certain assets and liabilities using tax rates expected to be in effect when the temporary differences reverse. A valuation allowance is provided when it is more likely than not that some portion or the entire deferred tax asset will not be realized. Accounting for Uncertainty in Income Taxes The Company recognizes the effect of tax positions only when they are more likely than not to be sustained. Management has determined that the C ompany had no uncertain tax positions that would require financial statement recognition or disclosure. The C ompany is no longer subject to U.S. federal, state or local income tax examinations for periods prior to 2012. Net Loss Per Share of Common Stock Basic net loss per common share is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period, without consideration for potentially dilutive securities. For purposes of the diluted net loss per share calculation, preferred stock, convertible notes payable-affiliated entities, stock options, restricted stock and warrants are considered to be potentially dilutive securities. Because the Company has reported a net loss for the years ended March 31, 2016, 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 1,130,000 , 1,000,000 and 1,630,000 at March 31, 2016, 2015 and 2014, respectively, and have not been included in the dilutive weighted average shares of common stock outstanding, as their effects are anti-dilutive. Recently Issued Accounting Pronouncements In May 2014, the 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 potential 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 potential impact it will have 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 July 2015, FASB issued ASU 2015-11, Inventory: Simplifying the Measurement of Inventory , which changes the measurement principle for inventory from the lower of cost or market to lower of cost and net realizable value. The ASU also eliminates the requirement for these entities to consider replacement cost or net realizable value less an approximately normal profit margin when measuring inventory. This guidance is effective for fiscal years and interim periods beginning after December 15, 2016. The Company does not expect the adoption of this guidance to have a material effect on its 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. In November 2015, the FASB issued ASU 2015-17, Income Taxes: Balance Sheet Classification of Deferred Taxes . This update, which simplifies the presentation of deferred income taxes, requires that deferred tax liabilities and assets be classified as non-current in a classified statement of financial position. The guidance is effective for financial statements issued for annual periods beginning after December 15, 2017, and interim periods within annual periods beginning after December 15, 2018. Earlier adoption is permitted for all entities as of the beginning of an interim or annual reporting period. This amendment may be applied either prospectively or retrospective ly to all periods presented. The Company decided to early adopt this ASU on a prospective basis with no impact on the Company’s Consolidated Balance Sheets. In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Recognition and Measurement of Financial Instruments and Financial Liabilities . This update requires that equity investments (except those accounted for under the equity method of accounting or those that result in consolidation) be measured at fair value with changes in fair value recognized in net income. The amendments in this update also simplify the impairment assessment of equity investments without readily determinable fair values. This update is effective for our fiscal y ear beginning April 1, 2018. In February 2016, the FASB issued ASU 2016-02, Leases . The ASU amends a number of aspects of lease accounting, including requiring lessees to recognize operating leases with a term greater than one year on their balance sheet as a right-of-use asset and corresponding lease liability, measured at the present value of the lease pa yments. The ASU also requires disclosure of key information about leasing arrangements to increase the transparency and comparability among organizations. The accounting for lessors does not fundamentally change except for changes to conform and align guidance to the lessee guidance as well as to the new revenue recognition guidance in ASU 2014-09. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation, Improvements to Employee Share-Based payment Accounting (Topic 718) . This update is intended to provide simplification of the accounting for share based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. This update is effective for our fiscal year beginning April 1 , 2017. Early adoption is permitted. I n April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing . ASU 2016-10 is intended to reduce the cost and complexity of applying the guidance in the FASB's new revenue standard on identifying performance obligations, and is also intended to improve the operability and understandability of the licensing implementation guidance. The effective date for ASU 2016-10 is the same as for ASU 2014-09 Management is evaluating the impact of the new guidance will have on its c onsolidated f inancial s tatements. Subsequent Events Evaluation by Management Management has evaluated subsequent events for disclosure and/or recognition in the financial statements through the date that the financial statements were issued.

Intangible Assets	5. 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 March 31, 201 6 for which the Company w ould re cognize any impairment. During the year ended March 31, 2016 , 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 9 ), upon FCC approval. Also during the period, the Company entered into an agreement with a third party to exchange wireless licenses. Both exchanges occurred within the year ended March 31, 2016.

Income Taxes [Abstract]
Income Taxes	10. Income Taxes The C ompany had federal and state net operating loss carryforwards of approximately $55.3 million at March 31, 201 6 expiring in varying amounts from 2021 through 2036 . The C ompany has deferred tax assets of approximately $20.2 million and $14.7 million relating to these net operating loss carryforwards and stock based compensation expense at March 31, 201 6 and 201 5 , respectively. Federal net operating loss carryforwards are subject to limitations as a result of the change in ownership (see N ote 1) as defined under Internal Revenue Code Section 382. State net operating loss carryforwards are subject to limitations which differ from federal law in that they may not allow the carryback of net operating losses, and have shorter carryforward periods. Due to the uncertainty with respect to the realization of these deferred tax assets the company recorded a valuation allowance for the entire amount. The difference between the tax benefit at the statutory rate and the effective tax rate is attributable to a full valuation allowance placed upon the deferred tax asset. Net deferred tax assets and liabilities consist of the following as of March 31, 201 6 and 201 5 :     At March 31, 2016 2015  Deferred tax asset  Allowance for uncollectible accounts $ 974 $ 2,951  Property and equipment — 181,422  Accrued expenses 183,265 8,605  Deferred revenue 2,365,180 2,632,248  Asset retirement obligation 75,312 —  Other liabilities 166,853 —  Net operating loss carryforward 20,462,573 10,609,567  Stock compensation expense 1,271,901 2,576,599  Total deferred tax asset 24,526,058 16,011,392  Deferred tax liability  Property and equipment (202,252) —  Intangible assets (4,134,386) (1,340,742)  Total deferred tax liability (4,336,638) (1,340,742)  Total deferred tax assets and liabilities 20,189,420 14,670,650  Valuation allowance (20,189,420) (14,670,650)  Net deferred tax assets and liabilities $ — $ —

Stock Acquisition Rights, Stock Options and Warrants	11. Stock Acquisition Rights, Stock Options and Warrants The C ompany established the pdvWireless 2014 Stock Plan (the “2014 Stock Plan”) to attract, retain and reward individuals who contribute to the growth and profitability of the C ompany. This 2014 Stock Plan superseded previous stock plans although under such previous plans, 51,512 stock options were outstanding and 51,028 stock options were vested as of March 31, 201 6 . The C ompany’s Board of Directors has reserved 2,538,234 shares of common stock for issuance under its 2014 Stock Plan as of March 31, 2016 . The number of shares will continue to automatically increase each January 1 st through January 1, 2024 by an amount equal to the lesser of (i) 5% of the number of shares of common stock issued and outstanding on the immediately preceding December 31 or (ii) a lesser amount determined by the Board of Directors. F or the year ended March 31, 2016, the C ompany awarded certain employees of the C ompany 274,000 options to purchase shares of common stock with a weighted average exercise price of $33.70 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 accelerated vesting and other such terms as determined by the Board of Directors.

In connection with the June 2014 Private Placement, the C ompany converted all outstanding shares of the company’s Series AA Preferred Stock into 748,722 shares of its common stock, exchanged 661,581 outstanding warrants to purchase shares of Series AA Preferred Stock into 29,809 shares of common stock, and converted the remaining options and warrants to purchase shares of the Series AA Preferred Stock into options or warrants to purchase shares of the common stock, and converted restricted stock units for shares of the company’s Series AA Preferred Stock into restricted stock units for shares of common stock. Restricted Stock and Restricted Stock Units A summary of restricted stock activity for the years ended March 31, 2016 and 2015 is as follows:     Weighted  Average  Restricted Grant Day  Stock Fair Value  Restricted stock outstanding at March 31, 2014 — $ —  Granted 83,804 20.00  Vested (83,804) (20.00)  Restricted stock outstanding at March 31, 2015 — —  Granted 140,972 26.47  Forfeited (100) 26.26  Vested — —  Restricted stock outstanding at March 31, 2016 140,872 $ 26.47 The C ompany recognizes compensation expense for restricted stock on a straight line basis 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 C ompany o r a date certain in the future. Stock compensation expense related to restricted stock was approximately $334,000 for the year ended March 31, 2016 and for the 83,804 shares issued in the year ended March 31, 2015 was $1,676,080 . Stock compensation expense for restricted stock is accounted for in general and administrative expense in the Company’s Consolidated Statement of Operations. At March 31, 201 6 , there was $3.4 million of unvested compensation expense of the restricted stock, which is expected to be recognized over a weighted average period of 3.6 years. Performance Stock Units During the year ended March 31, 2016 , the Company awarded 37,295 performance stock units under the 2014 Stock Plan . These performance stock units represent the number of shares of the Company’s common stock that the recipient would receive upon the Company’s attainment of the applicable performance goal s . The units will vest in full upon attainment of the performance goals. Performance is based upon achievement, prior to January 13, 2020, of (A) a Final Order f rom the FCC providing for the creation and allocation of licenses for spectrum in the 900 MHz band consisting of paired blocks of contiguous spectrum, each containing at least 3 MHz of contiguous spectrum, authorized for broadband wireless communications uses and (B) the lack of objection by the Company's Board of Directors to the terms and conditions (including, but not limited to, the rebanding, clearing and relocation procedures, license assignment and award mechanisms, and technical and operational rules) set forth or referenced in the Final Order. A summary of the Performance stock activity for the years ended March 31, 2016 and 2015 is as follows:    Weighted  Average  Performance Grant Day  Stock Fair Value  Performance stock outstanding at March 31, 2015 — $ —  Granted 37,295 25.81  Forfeited — —  Vested — —  Restricted stock outstanding at March 31, 2016 37,295 $ 25.81  For the year end March 31, 2016, there was no stock compensation expense recognized for the performance units. At March 31, 2016, there was approximately $963,000 of unvested compensation expense. Stock Options A summary of Stock Option activity f or the years ended March 31, 2016 and 2015 is as follows:     Options Weighted Average Exercise Price Weighted Average Contractual Term Aggregate Intrinsic Value  Options outstanding at March 31, 2014 56,634 $ 19.68  Options granted 1,391,457 20.93  Options forfeited/expired (22,140) (21.72)  Options outstanding at March 31, 2015 1,425,951 19.38  Options granted 274,000 33.70  Options exercised (3,306) (13.63)  Options forfeited/expired (3,445) (41.22)  Options outstanding at March 31, 2016 1,693,200 $ 22.91 8.36 $ 20,737,452  Exercisable at March 31, 2016 484,340 $ 21.38 7.97 $ 6,426,669  Total vested or expected to vest at March 31, 2016 1,659,487 $ 21.38 8.36 $ 20,363,906  Additional information regarding stock options outstanding at March 31, 201 6 is as follows:    Weighted  Weighted Average  Average Weighted Exercise Price  Exercise Number Remaining Average Options of Shares  Prices Outstanding Life in Years Exercise Price Exercisable Exercisable  $ 13.25 - $ 20.00 1,170,868 8.06 $ 19.74 339,196 $ 19.11  21.00 - 46.23 425,750 9.16 25.91 136,000 25.16  47.10 - 72.85 96,582 8.56 48.09 9,144 49.51  1,693,200 8.36 $ 22.91 484,340 $ 21.38   The fair value of options granted is estimated on the date of grant using the Black-Scholes option valuation model. This stock-based compensation expense valuation model requires the C ompany to make assumptions and judgments regarding the variables used in the calculation. These variables include the expected term, the expected volatility of the C ompany’s common stock, expected risk-free interest rate, forfeiture rate and expected dividends. The C ompany calculates it expected term and volatility from the historical volatilities and terms of selected comparable public companies within its industry along with the Company’s short history regarding these variables. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for periods corresponding with the expected life of the option. The C ompany estimates its forfeiture rate based on an analysis of its actual forfeitures and will continue to evaluate the appropriateness of the forfeiture rate based on actual forfeiture experience, analysis of employee turnover and other factors. The C ompany has never paid, and does not anticipate paying, any cash dividends in the foreseeable future, and therefore uses an expected dividend yield of zero in the option-pricing model.  The following assumptions were used to calculate the fair value of options:     Year Ended Year Ended  March 31, 2016 March 31, 2015  Risk-free interest rate 1.23% to 1.71% 1.28% to 1.66%  Dividend yield -% -%  Volatility 40% 40% to 47%  Expected term 5 years 5 years  Forfeiture rate 2% 0%  Performance Stock Options  During the year ended March 31, 2016 , the Company awarded an executive officer an option to purchase 50,000 shares of common stock with an exercise price of $25.81 that vest immediately upon meeting certain performance conditions . These options have a ten year contractual life. The performance options will vest in full upon attainment of the performance goals. Performance is based upon achievement, prior to January 13, 2020, of (A) a Final Order f rom the FCC providing for the creation and allocation of licenses for spectrum in the 900 MHz band consisting of paired blocks of contiguous spectrum, each containing at least 3 MHz of contiguous spectrum, authorized for broadband wireless communications uses and (B) the lack of objection by the Company's Board of Directors to the terms and conditions (including, but not limited to, the rebanding, clearing and relocation procedures, license assignment and award mechanisms, and technical and operational rules) set forth or referenced in the Final Order.  A summary of the Performance Stock Options as of March 31, 2016 is as follows:    Performance Options Weighted Average Exercise Price Weighted Average Contractual Term Aggregate Intrinsic Value  Performance Options outstanding at March 31, 2015 — $ —  Performance Options granted 50,000 25.81  Performance Options exercised — —  Performance Options forfeited/expired — —  Performance Options outstanding at March 31, 2016 50,000 $ 25.81 9.79 $ 426,500   Stock compensation expense related to the amortization of the fair value of stock options issued was approximately $4,646,000 , $5,288,000 and $79,000 for the years ended March 31, 201 6 , 201 5 , and 201 4 respectively. There was no stock compensation expense related to the performance stock options issued. Stock compensation expense is included as part of general and administrative expense in the accompanying Consolidated S tatement of O perations. The weighted average fair value for the stock option awards granted for the fiscal year ended March 31, 201 6 was $12. 04 . As of March 31, 201 6 , there was approximately $5.9 million of unrecognized compensation cost related to non-vested s hare options granted under the C ompany’s stock option plans , of which $5.4 million pertains to the non-performance based stock options . The cost is expected to be recognized over a weighted-average period of 2.8 years. Warrants A summary of Warrant activity is as follows:     Warrants Weighted Average Exercise Price  Warrants outstanding at March 31, 2014 686,417 $ 30.80  Warrants converted into 29,809 shares of common stock (661,581)  Expired (18,797) 165.57  Warrants outstanding at March 31, 2015 6,039 $ 82.79  Issued, cancelled expired —  Warrants outstanding at March 31, 2016 6,039 $ 82.79  Additional information regarding Warrants outstanding at March 31, 201 6 is as follows:     Exercise Price Number Outstanding Weighted Average Remaining Life in Years Weighted Average Exercise Price  $82.79 6,039 0.17 $82.79  The outstanding warrants are immediately exercisable into 6,039 shares of common stock at March 31, 201 6 and expire in June 2016. Motorola Investment On September 15, 2014, Motorola invested $10.0 million to purchase 500,000 Class B Units of the C ompany’s subsidiary, PDV Spectrum Holding Company, LLC (at a price equal to $20.00 per unit). The C ompany 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 C ompany also has the right to force Motorola’s conversion into shares of its common stock on the occurrence of certain corporate events or at its election after September 15, 2016. Motorola is not entitled to any assets, profits or distributions from the operations of the subsidiary. In addition, Motorola’s conversion ratio from Class B Units to shares of the Company’s common stock is fixed on a one-for-one basis, and is not dependent on the performance or valuation of either the company or the subsidiary. The Class B Units have no redemption or call provisions and can only be converted into shares of the C ompany’s common stock. Management has determined that this investment does not meet the criteria for temporary equity or non-controlling interest due to the limited rights that Motorola has as a holder of Class B Units, and accordingly has presented this investment as part of its permanent equity within Additional Paid-in Capital in the accompanying financial statements.

Summary of Significant Accoun24

Summary of Significant Accounting Policies (Policies)	12 Months Ended

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, asset retirement obligations, the carrying amount of long-lived assets under construction in process, valuation allowance on the Company’s deferred tax assets, and recoverability of intangible assets. The Company is also required to make certain estimates with regard to the valuation of awards and forfeiture rates for its share-based award programs. Estimates and assumptions are reviewed periodically and the effects of revision are reflected in the financial statements in the period they are deemed to be necessary. Accordingly actual results could differ from those estimates. The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries, including PDV Spectrum Holding Company, LLC formed in April 2014. All significant intercompany accounts and transactions have been eliminated in consolidation.
Reclassifications	Reclassifications Certain prior year amounts have been reclassified to conform to the financial statements for the year ended March 31, 2016 financial statement presentation. These reclassifications had no effect on previously reported results of operations, cash flows, assets, liabilities or equity for the years presented.
Cash and Cash Equivalents	Cash and Cash Equivalents All highly liquid investments with maturities of three months or less of the time of purchase are considered cash equivalents. Cash equivalents are stated at cost, which approximates quoted market value and include amounts held in money market funds.
Allowance for 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 March 31, 2016 and March 31, 2015, management provided an allowance of $2,633 and $7,977 , respectively, for certain slow paying accounts.
Inventory	 Inventory Inventories, which consist of vehicle-mounted devices and handsets, are valued at the lower of cost or market, with market being defined as replacement value using the First In, First Out method. Provisions are made periodically to reduce any excess, obsolete or slow moving inventory to its net realizable value.
Property and Equipment	Property and Equipment Property and equipment is stated at cost. Depreciation is computed using the straight-line method over the shorter of the estimated useful lives of the assets or the applicable lease term. 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, assets being constructed that are not ready to be placed into service, and assets that are not currently in 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.
Accounting for Asset Retirement Obligations	Accounting for Asset Retirement Obligations An asset retirement obligation is evaluated and recorded as appropriate on assets for which the Company has a legal obligation to retire. The Company records a liability for an asset retirement obligation and the associated asset retirement cost at the time the underlying asset is acquired and put into service. Subsequent to the initial measurement of the asset retirement obligation, the obligation is adjusted at the end of each period to reflect the passage of time and changes in the estimated future cash flows underlying the obligation, if any. The Company enters into long-term leasing arrangements primarily for tower site location s. The Company constructs assets at these locations and, in accordance with the terms of many of these agreements, the Company is obligated to restore the premises to their original condition at the conclusion of the agreements, generally at the demand of the other party to these agreements. The Company recognizes the fair value of a liability for an asset retirement obligation and capitalizes that cost as part of the cost basis of the related asset, depreciating it over the useful life of the related asset . As of March 31, 2016, the Company had an asset retirement obligation of $ 203,546 .
Intangible Assets	Intangible Assets Intangible assets are wireless licenses that will be used to provide the exclusive right to utilize designated radio frequency spectrum to provide wireless communication services. While licenses are issued for only a fixed time, generally ten years, such licenses are subject to renewal by the FCC. License renewals have occurred routinely and at nominal cost. There are currently no legal, regulatory, contractual, competitive, economic or other factors that limit the useful life of the company’s wireless licenses. As a result, the wireless licenses are treated as an indefinite-lived intangible asset. The Company evaluates the useful life determination for wireless licenses each year to determine whether events and circumstances continue to support an indefinite useful life. The licenses are tested for impairment on an aggregate basis, as the Company will be utilizing the wireless licenses on an integrated basis as a part of developing its nationwide network. The Company considers estimates of valuation methods to perform the test of the fair values of wireless licenses annually including market based and discounted cash flow approaches.
Patent Costs	Patent Costs Costs to acquire a patent on certain aspects of the Company’s technology have been capitalized. These amounts are amortized, subject to periodic evaluation for impairment, over statutory lives following award of the patent. Gross patent costs are $570,994 at March 31, 2016 and $558,696 at March 31, 2015 and the associated accumulated amortization amounted to $348,634 and $337,914 , respectively. Amortization expense was $10,720 , $34,609 , and $42,830 for the years ended March 31, 2016 , 2015 and 2014 , respectively. The amortization expense is estimated to aggregate $15,000 per year over the next five year period. Renewal costs are expensed when incurred.
Long-Lived Asset Impairment	Long-Lived Asset Impairment The Company evaluates long-lived assets, other than intangible assets with indefinite lives, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. Asset groups are determined at the lowest level for which identifiable cash flows are largely independent of cash flows of other groups of assets and liabilities. When the carrying amount of a long-lived asset group is not recoverable and exceeds its fair value, an impairment loss is recognized equal to the excess of the asset group’s carrying value over the estimated fair value.
Fair Value of Financial Instruments	Fair Value of Financial Instruments Financial instruments, including cash and cash equivalents, accounts receivable, accounts payable, and accrued expenses are carried at cost, which management believes approximates fair value because of the short term maturity of these instruments.
Revenue Recognition	Revenue Recognition The Company recognizes revenue in the period 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 d eferred r evenue 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. Judgment is required to properly identify the accounting units of the multiple deliverable transactions and to determine the manner in which revenue should be allocated among the units of accounting. 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 relative selling price for each deliverable is determined using vendor-specific objective evidence (“V SOE”) of selling price or third party evidence of selling price if VSOE does not exist. If neither VSOE nor third party evidence of selling price exist, the Company uses its best estimate of the selling price for the deliverable. The Company has determined that the rental of user devices in connection with service contracts for its DispatchPlus service a re 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.
Shipping and Handling Costs	Shipping and Handling Costs Costs associated to shipping and handling of two-way radios to dealers or end-user customers are recognized as incurred and included in cost of revenue in the Consolidated Statements of Operations.
Indirect Sales Commissions	Indirect Sales Commissions Cash consideration given to a dealer is presumed to be a reduction of revenue unless the Company receives, or will receive, an identifiable benefit in exchange for the consideration, and the fair value of such benefit can be reasonably estimated, in which case the consideration will be recorded as a selling expense. The Company compensates its indirect sales representatives with an upfront commission and residual fees based on a customer’s continued use of its DispatchPlus s ervice . When a commission is earned solely due to the selling activity relating to the Company’s DispatchPlus service , the cost is recorded as a selling expense. The Company reviews and records the e stimated incentives payable to the indirect sales representatives as accrued expense on a monthly basis.
Product Development Costs	Product Development Costs The Company charges all product and development costs to expense as incurred. Types of expense incurred in product and development include employee compensation, consulting, travel, facility costs and equipment and technology costs.
Advertising and Promotional Expense	Advertising and Promotional Expense The Company expenses advertising and promotional costs as incurred. Cooperative advertising reimbursements from vendors are recorded net of advertising and promotional expense in the period in which the related advertising and promotional expense is incurred. Advertising and promotional expense was $161,257 for the year ended March 31, 2016. No advertising costs were incurred in 2015 and 2014.
Stock Compensation	Stock Compensation The Company accounts for restricted stock, restricted stock units, performance units, and 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 Consolidated 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. The fair value of restricted stock , restricted stock units and performance units are measured based upon the quoted closing market price for the stock on the date of grant. The compensation cost for the restricted stock and restricted stock units is recognized on a straight-line basis over the vesting period. The compensation cost for the performance units is recognized when the performance criteria are expected to be complete. No tax benefits were attributed to the share-based compensation expense because the Company maintained a full valuation allowance for all net d eferred tax assets.
Income Taxes	Income Taxes The Company follows the liability method of accounting for income taxes. Under this method, taxes consist of taxes currently payable plus those deferred due to temporary differences between the financial statement carrying amounts and the tax bases of certain assets and liabilities using tax rates expected to be in effect when the temporary differences reverse. A valuation allowance is provided when it is more likely than not that some portion or the entire deferred tax asset will not be realized.
Accounting for Uncertainty in Income Taxes	Accounting for Uncertainty in Income Taxes The Company recognizes the effect of tax positions only when they are more likely than not to be sustained. Management has determined that the C ompany had no uncertain tax positions that would require financial statement recognition or disclosure. The C ompany is no longer subject to U.S. federal, state or local income tax examinations for periods prior to 2012.
Net Loss Per Share of Common Stock	Net Loss Per Share of Common Stock Basic net loss per common share is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period, without consideration for potentially dilutive securities. For purposes of the diluted net loss per share calculation, preferred stock, convertible notes payable-affiliated entities, stock options, restricted stock and warrants are considered to be potentially dilutive securities. Because the Company has reported a net loss for the years ended March 31, 2016, 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 1,130,000 , 1,000,000 and 1,630,000 at March 31, 2016, 2015 and 2014, respectively, and have not been included in the dilutive weighted average shares of common stock outstanding, as their effects are anti-dilutive.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In May 2014, the 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 potential 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 potential impact it will have 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 July 2015, FASB issued ASU 2015-11, Inventory: Simplifying the Measurement of Inventory , which changes the measurement principle for inventory from the lower of cost or market to lower of cost and net realizable value. The ASU also eliminates the requirement for these entities to consider replacement cost or net realizable value less an approximately normal profit margin when measuring inventory. This guidance is effective for fiscal years and interim periods beginning after December 15, 2016. The Company does not expect the adoption of this guidance to have a material effect on its 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. In November 2015, the FASB issued ASU 2015-17, Income Taxes: Balance Sheet Classification of Deferred Taxes . This update, which simplifies the presentation of deferred income taxes, requires that deferred tax liabilities and assets be classified as non-current in a classified statement of financial position. The guidance is effective for financial statements issued for annual periods beginning after December 15, 2017, and interim periods within annual periods beginning after December 15, 2018. Earlier adoption is permitted for all entities as of the beginning of an interim or annual reporting period. This amendment may be applied either prospectively or retrospective ly to all periods presented. The Company decided to early adopt this ASU on a prospective basis with no impact on the Company’s Consolidated Balance Sheets. In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Recognition and Measurement of Financial Instruments and Financial Liabilities . This update requires that equity investments (except those accounted for under the equity method of accounting or those that result in consolidation) be measured at fair value with changes in fair value recognized in net income. The amendments in this update also simplify the impairment assessment of equity investments without readily determinable fair values. This update is effective for our fiscal y ear beginning April 1, 2018. In February 2016, the FASB issued ASU 2016-02, Leases . The ASU amends a number of aspects of lease accounting, including requiring lessees to recognize operating leases with a term greater than one year on their balance sheet as a right-of-use asset and corresponding lease liability, measured at the present value of the lease pa yments. The ASU also requires disclosure of key information about leasing arrangements to increase the transparency and comparability among organizations. The accounting for lessors does not fundamentally change except for changes to conform and align guidance to the lessee guidance as well as to the new revenue recognition guidance in ASU 2014-09. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation, Improvements to Employee Share-Based payment Accounting (Topic 718) . This update is intended to provide simplification of the accounting for share based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. This update is effective for our fiscal year beginning April 1 , 2017. Early adoption is permitted. I n April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing . ASU 2016-10 is intended to reduce the cost and complexity of applying the guidance in the FASB's new revenue standard on identifying performance obligations, and is also intended to improve the operability and understandability of the licensing implementation guidance. The effective date for ASU 2016-10 is the same as for ASU 2014-09 Management is evaluating the impact of the new guidance will have on its c onsolidated f inancial s tatements.
