Notes to Financial Statements
Nature of Operations [Text Block]	Note 1. Organization and Nature of Business Towerstream Corporation (referred to as “Towerstream” or the “Company”) was incorporated in Delaware in December 1999. During its first decade of operations, the Company’s business activities were focused on delivering fixed wireless broadband services to commercial customers over a wireless network transmitting over both licensed and unlicensed radio spectrum. The Company’s fixed wireless service supports bandwidth on demand, wireless redundancy, virtual private networks, disaster recovery, bundled data and video services. The Company provides services to business customers in New York City, Boston, Chicago, Los Angeles, San Francisco, Seattle, Miami, Dallas-Fort Worth, Houston, Philadelphia, Las Vegas-Reno and Providence-Newport. The Company’s “Fixed Wireless business” has historically grown both organically and through the acquisition of five other fixed wireless broadband providers in various markets. In January 2013, the Company incorporated a wholly-owned subsidiary, Hetnets Tower Corporation (“Hetnets”), to operate a new business designed to leverage its fixed wireless network in urban markets to provide other wireless technology solutions and services. Hetnets built a carrier-class network which offered a shared wireless infrastructure platform, primarily for (i) co-location of customer owned antenna and related equipment and (ii) Wi-Fi access and offloading. The Company referred to this as its “Shared Wireless Infrastructure” or “Shared Wireless” business. During the fourth quarter of 2015, the Company determined to exit this business and curtailed activities in its smaller markets. The remaining network, located in New York City (or “NYC”), was the largest and had a lease access contract with a major cable company. As a result, the Company explored opportunities during the fourth quarter of 2015 and continuing into the first quarter of 2016 to sell the New York City network. As further described in Note 18, on March 9, 2016, the Company completed a sale and transfer of certain assets to the major cable company (the “Buyer”). The Asset Purchase Agreement provided that the Buyer would assume certain rooftop leases in NYC and acquire ownership of the Wi-Fi access points and related equipment associated with operating the network. The Company retained ownership of all backhaul and related equipment and the parties entered into a backhaul services agreement under which the Company will provide bandwidth to the Buyer at the locations governed by the leases. The agreement is for a three year period with two, one year renewals and is cancellable by the Buyer on sixty days’ notice. The operating results and cash flows for Hetnets have been presented as discontinued operating results in these consolidated financial statements. Assets associated with the New York City network have been presented as Assets Held for Sale.

Notes to Financial Statements
Liquidity and Management Plans [Text Block]	Note 2. Liquidity and Management Plans At December 31, 2015, the Company had cash and cash equivalents of approximately $15.1 million and working capital of approximately $13.5 million. Based on (i) current projections for revenues for its continuing operations, (ii) operating costs to support its continuing operations including the effect of cost reduction measures that are being implemented, and (iii) capital expenditures to support the network infrastructure, the Company believes that its current cash balances are sufficient to maintain operations and fulfill working capital requirements for the next twelve months from the date of filing this annual report. The Company has historically financed operations through private and public placement of equity securities, as well as debt financings and capital leases. The Company's ability to fund its longer term cash requirements is subject to multiple risks, many of which are beyond its control. Should additional funding be required, the Company may need to raise additional capital through the sale of equity or debt securities. There can be no assurances that the Company would be successful in raising additional capital.

Expenditures for maintenance and repairs which do not extend the useful life of the assets are charged to expense as incurred. Gains or losses on disposals of property and equipment are reflected in general and administrative expenses in the Company’s consolidated statements of operations. FCC Licenses. Long-Lived Assets The FASB’s guidance on asset retirement obligations addresses financial accounting and reporting for obligations associated with the retirement of tangible long-lived assets and the associated costs. This guidance requires the recognition of an asset retirement obligation and an associated asset retirement cost when there is a legal obligation associated with the retirement of tangible long-lived assets. The Company’s network equipment is installed on both buildings in which the Company has a lease agreement (“Company Locations”) and at customer locations. In both instances, the installation and removal of the Company’s equipment is not complicated and does not require structural changes to the building where the equipment is installed. Costs associated with the removal of the Company’s equipment at company or customer locations are not material, and accordingly, the Company has determined that it does not presently have asset retirement obligations under the FASB’s accounting guidance. Business Acquisitions The highest level of judgment and estimation involved in accounting for business acquisitions relates to determining the fair value of the customer relationships and network assets acquired. In each of the five acquisitions completed over the past four years, the highest asset value has been allocated to the customer relationships acquired. Determining the fair value of customer relationships involves judgments and estimates regarding how long the customers will continue to contract services with the Company. During the course of completing five acquisitions, the Company has developed a database of historical experience from prior acquisitions to assist in preparing future estimates of cash flows. Similarly, the Company has used its historical experience in building networks to prepare estimates regarding the fair value of the network assets that it acquires. Goodwill. Fair Value of Financial Instruments. Income Taxes. Revenue Recognition. Deferred Revenues. Advertising Costs. Stock-Based Compensation. Basic and Diluted Net Loss Per Share. The following common stock equivalents were excluded from the computation of diluted net loss per common share because they were anti-dilutive. The exercise of these common stock equivalents would dilute earnings per shares if the Company becomes profitable in the future.

Segments Recent Accounting Pronouncements. In May 2014, the FASB issued ASU No. 2014-09 (“ASU 2014-09”), “Revenue from Contracts with Customers,” which requires an entity to recognize revenue representing the transfer of promised goods or services to customers in an amount that reflects the consideration which the company expects to receive in exchange for those goods or services. ASU 2014-09 is intended to establish principles for reporting useful information to users of financial statements about the nature, amount, timing and uncertainty of revenues and cash flows arising from the entity’s contracts with customers. ASU 2014-09 will replace most existing revenue recognition guidance in Generally Accepted Accounting Principles (“GAAP”) when it becomes effective. The new standard is effective for the Company on January 1, 2018. Early application is only permitted as of January 1, 2017. The Company is currently evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. In June 2014, the FASB issued ASU No. 2014-12 (“ASU 2014-12”), “Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period,” which requires a performance target that affects vesting, and that could be achieved after the requisite service period, be treated as a performance condition. ASU 2014-12 states that the performance target should not be reflected in estimating the grant date fair value of the award. ASU 2014-12 clarifies that compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the periods for which the requisite service has already been rendered. The new standard is effective for the Company on January 1, 2016. The Company does not expect adoption of ASU 2014-12 to have a significant impact on its consolidated financial statements. In August 2014, the FASB issued ASU No. 2014–15 (“ASU 2014-15”), “Presentation of Financial Statements – Going Concern.” ASU 2014-15 provides GAAP guidance on management’s responsibility in evaluating whether there is substantial doubt about a company’s ability to continue as a going concern and about related footnote disclosures. For each reporting period, management will be required to evaluate whether there are conditions or events that raise substantial doubt about a company’s ability to continue as a going concern within one year from the date the financial statements are issued. The new standard is effective for the Company on January 1, 2017. The Company does not expect the adoption of ASU 2014–15 to have a significant impact on its consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-03 (“ASU 2015-03”), “Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs.” ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability, consistent with debt discounts, instead of being presented as an asset. ASU 2015-03 is effective for the Company on January 1, 2016. Once adopted, entities are required to apply the new guidance retrospectively to all prior periods presented. The retrospective application represents a change in accounting principle. Early adoption is permitted for financial statements that have not been previously issued. The Company is currently evaluating the effect that ASU 2015-03 will have on its consolidated financial statements and related disclosures. In May 2015, the FASB issued ASU No. 2015-07 (“2015-07”), “Fair Value Measurement.” ASU 2015-07 removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient. The amendments also remove the requirement to make certain disclosures for all investments that are eligible to be measured at fair value using the net asset value per share practical expedient. ASU 2015-07 is effective for the Company on January 1, 2016. Early adoption is permitted. The Company does not expect the adoption of ASU 2015–07 to have a significant impact on its consolidated financial statements. In September 2015, the FASB issued ASU No. 2015-16 (“ASU 2015-16”), “Business Combinations (Topic 805), Simplifying the Accounting for Measurement-Period Adjustments”. The update requires that the acquirer in a business combination recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined (not retrospectively as with prior guidance). Additionally, the acquirer must record in the same period’s financial statements the effect on earnings of changes in depreciation, amortization or other income effects as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the time of acquisition. The acquiring entity is required to disclose, on the face of the financial statements or in the footnotes to the financial statements, the portion of the amount recorded in current period earnings, by financial statement line item, that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. ASU 2015-16 is effective for the Company on January 1, 2016. The adoption of this standard is not expected to have a material impact on its consolidated financial statements. In September 2015, the FASB issued ASU No. 2015-16 (“ASU 2015-16”), “Business Combinations (Topic 805), Simplifying the Accounting for Measurement-Period Adjustments”.

ASU 2015-16 is effective for the Company on January 1, 2016. The adoption of this standard is not expected to have a material impact on its consolidated financial statements. In November 2015, the FASB has issued an update to ASU No. 2015-17 (“ASU 2015-17”) “Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes.” The update requires a company to classify all deferred tax assets and liabilities as noncurrent. The update of ASU 2015-17 is effective for the Company on January 1, 2018. The Company does not expect the adoption of the update of ASU 2015–17 to have a significant impact on its consolidated financial statements. In January 2016, the FASB issued ASU No. 2016-01 (“ASU 2016-01”), “Financial Instruments – Overall (Subtopic 825-10)”. ASU 2016-01 updates certain aspects of recognition, measurement, presentation and disclosure of financial instruments. The new guidance is effective for us on January 1, 2018. The Company does not expect the adoption of ASU 2016–01 to have a significant impact on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02 (“ASU 2016-02), “Leases (Topic 842).” ASU 2016-02 requires a lessee to recognize a lease liability for the obligation to make lease payments and a right-to-use asset for the right to use the underlying asset for the lease term. ASU 2016-02 is effective for the Company on January 1, 2019. Early adoption is permitted. The Company is currently evaluating the effect that ASU 2016-02 will have on its consolidated financial statements.

Business Combination Disclosure [Text Block]	Note 4. Business Acquisitions Delos Internet In February 2013, the Company completed the acquisition of Delos Internet (“Delos”). The Company obtained full control of Delos and determined that the acquisition was a business combination to be accounted for under the acquisition method. The following table summarizes the consideration transferred and the amounts of identified assets acquired and liabilities assumed at the acquisition date. The number of shares issued was determined based on the closing price of the Company’s common stock on the February 28, 2013 closing date which was $2.47. Original Adjustments Final Fair value of consideration transferred: Cash $ 225,000 $ - $ 225,000 Common stock 1,071,172 (119,916 ) 951,256 Other liabilities assumed - 36,733 36,733 Capital lease obligations assumed 128,929 - 128,929 Total consideration transferred 1,425,101 (83,183 ) 1,341,918 Fair value of identifiable assets acquired and liabilities assumed: Cash 2,058 - 2,058 Accounts receivable 80,524 1,286 79,238 Property and equipment 826,524 18,824 807,700 Security deposits 1,993 - 1,993 Accounts payable (26,970 ) 2,566 (29,536 ) Deferred revenue (62,110 ) (2,135 ) (59,975 ) Other liabilities (89,930 ) - (89,930 ) Total identifiable net tangible assets 732,089 20,541 711,548 Customer relationships 1,634,469 - 1,634,469 Total identifiable net assets 2,366,558 20,541 2,346,017 Gain on business acquisition $ 941,457 $ 62,642 $ 1,004,099 The Company recognized a gain on business acquisition of $1,004,099 which is included in other income (expense) in the Company’s consolidated statements of operations for the year ended December 31, 2013. The challenging economic environment during 2012 made it difficult for smaller companies like Delos to raise sufficient capital to sustain their growth. As a result, the Company was able to acquire the customer relationships and wireless network of Delos at a discounted price. In May 2013, the Company finalized the purchase price of Delos which resulted in a reduction of approximately $21,000 of identifiable net assets and an increase in the gain on business acquisition of approximately $63,000. The purchase price adjustment resulted in a decrease in the number of shares of common stock issued to Delos of 48,549 from 433,673 to 385,124 shares. The results of operations of Delos have been included in the Company’s consolidated statements of operations since the completion of the acquisition in February 2013. Revenues generated from customers acquired from Delos totaled approximately $517,000 for the year ended December 31, 2013. During the year ended December 31, 2013, the Company incurred approximately $99,000 of third-party costs in connection with the Delos acquisition. These expenses are included in the general and administrative expenses in the Company’s consolidated statements of operations. Pro Forma Information The following table reflects the unaudited pro forma results from continuing operations had the Delos acquisition taken place at the beginning of the 2013 period: Year Ended December 31, 2013 Revenues $ 32,005,154 Amortization expense 3,159,196 Total operating expenses 41,844,651 Net loss (9,131,670 ) Basic net loss per share $ (0.14 ) The pro forma information presented above does not purport to present what actual results would have been had the Delos acquisition actually occurred at the beginning of 2013 nor does the information project results for any future period.

Disposal Groups, Including Discontinued Operations, Disclosure [Text Block]	Note 5. Discontinued Operations and Assets Held for Sale In January 2013, the Company incorporated a wholly-owned subsidiary, Hetnets Tower Corporation (“Hetnets”), to operate a new business designed to leverage its fixed wireless network in urban markets to provide other wireless technology solutions and services. Hetnets built a carrier-class network which offered a shared wireless infrastructure platform, primarily for (i) co-location of customer owned antenna and related equipment and (ii) Wi-Fi access and offloading. The Company referred to this as its “Shared Wireless Infrastructure” or “Shared Wireless” business. During the fourth quarter of 2015, the Company determined to exit this business and curtailed activities in its smaller markets, and recognized charges of $3,284,466 representing the estimated cost to settle lease obligations, $1,618,540 to write-off network assets which could not be redeployed into the fixed wireless network, $45,114 related to security deposits which are not expected to be recovered, and $410,991 related to the accelerated expensing of deferred acquisition costs. The remaining network, located in New York City (or “NYC”), was the largest and had a lease access contract with a major cable company. As a result, the Company explored opportunities during the fourth quarter of 2015 and continuing into the first quarter of 2016 to sell the New York City network. As further described in Note 18, on March 9, 2016, the Company completed a sale and transfer of certain assets to the major cable company (the “Buyer”). The Asset Purchase Agreement provided that the Buyer would assume certain rooftop leases in NYC and acquire ownership of the Wi-Fi access points and related equipment associated with operating the network. The Company retained ownership of all backhaul and related equipment and the parties entered into a backhaul services agreement under which the Company will provide internet bandwidth to the Buyer at the locations governed by the leases. The agreement is for a three year period with two, one year renewals and is cancellable by the Buyer on sixty days’ notice. The operating results and cash flows for Hetnets have been presented as discontinued operating results in these consolidated financial statements. Assets associated with the New York City network have been presented as Assets Held for Sale. Discontinued Operations A more detailed presentation of loss from discontinued operations is set forth below. There has been no allocation of consolidated interest expense to discontinued operations. General and administrative expenses for 2015 includes $1,618,540 to write-off network assets which could not be deployed.

The customer contracts acquired in the Delos acquisition are being amortized over a 50 month period ending April 2017. As of December 31, 2015, the remaining amortization period for the Delos acquisition was 16 months. Balances related to the Company’s other acquisitions have been fully amortized. Future amortization expense is as follows: Years Ending December 31, 2016 392,272 2017 130,758 $ 523,030 FCC licenses have an indefinite life but are subject to periodic renewal. The Company recognized an impairment charge of $534,555 in 2015 related to a spectrum license. The Company determined that changes being considered by the FCC would make commercial use of the spectrum uncertain and costly, and that the coverage area of the spectrum was not consistent with its focus on dense urban markets. The expense is included in general and administrative expenses in the statement of operations. Based on prices paid at recent spectrum auctions, the Company believes that the remaining spectrum has a fair value higher than the cost basis at which it is reported in these financial statements.

Debt Disclosure [Text Block]	Note 10. Long-Term Debt In October 2014, the Company entered into a loan agreement (the "Loan Agreement") with Melody Business Finance, LLC (the "Lender") which provided the Company with a five-year $35 million term loan (the "Financing" or "Note"). The Note was issued at a 3% discount totaling $1,050,000 which is being amortized over the term of the Note. The Company recognized interest expense of $340,899 and $95,365 in connection with the amortization of this discount for the years ended December 31, 2015 and 2014, respectively. The unamortized balance totaled $613,736 and $954,635 at December 31, 2015 and 2014 respectively. The loan bears interest payable in cash at a rate equal to the greater of (i) the sum of the one month Libor rate on each payment date plus 7% or (ii) 8% per annum, and additional paid in kind (“PIK”), or deferred, interest that accrues at 4% per annum. The Company paid $2,906,695 of interest and accrued $1,453,347 of PIK interest for the year ended December 31, 2015. The Company paid $591,111 of interest and accrued $295,556 of PIK interest for the year ended December 31, 2014. PIK interest is included in Interest expense, net in the accompanying consolidated statements of operations. In October 2019, the Company must repay the principal amount outstanding plus all accrued interest. The Company has the option of prepaying the loan (i) on or before October 16, 2016 (the “Second Anniversary”), but only in full, and (ii) at any time after the Second Anniversary, in the minimum principal amount of $5,000,000 or in full if the balance outstanding is less. All optional prepayments are subject to certain premiums. Mandatory prepayments are required upon the occurrence of certain events, including but not limited to the (i) sale, lease, conveyance or transfer of certain assets, (ii) issuance or incurrence of indebtedness other than certain permitted debt, (iii) issuance of capital stock redeemable for cash or convertible into debt securities and (iv) any change of control. As further set forth in a security agreement (the “Security Agreement”), repayment of the loan is secured by a first priority lien and security interest in all of the assets of the Company and its subsidiaries, excluding capital stock of the Company, and certain capital leases, contracts and assets secured by purchase money security interests. The Loan Agreement also contains representations and warranties by the Company and the Lender, certain indemnification provisions in favor of the Lender and customary covenants (including limitations on other debt, liens, acquisitions, investments and dividends), and events of default (including payment defaults, breaches of covenants, a material impairment in the Lender’s security interest or in the collateral, and events relating to bankruptcy or insolvency). Upon the occurrence of an event of default, an additional 5% interest rate will be applied to the outstanding loan balances, and the Lender may terminate its lending commitment, declare all outstanding obligations immediately due and payable, and take such other actions as set forth in the Loan Agreement. As of December 31, 2015, the Company was in compliance with all of the debt covenants. In connection with the Loan Agreement and pursuant to a Warrant and Registration Rights Agreement, the Company issued warrants (the “Warrants”) to purchase 3,600,000 shares of common stock of which two-thirds have an exercise price of $1.26 and one-third have an exercise price of $0.01, subject to customary adjustments under certain circumstances. The Warrants have a term of seven and a half years. The fair value of the warrants granted to the Lender of $2,463,231 was calculated using the Black-Scholes option pricing model and recorded as a debt discount. The debt discount is being amortized over the term of the Note using the effective interest rate. The Company recognized interest expense of $799,727 and $223,719 in connection with the amortization of this discount for the years ended December 31, 2015 and 2014, respectively. The unamortized balance totaled $1,439,785 and $2,239,512 at December 31, 2015 and 2014, respectively. The warrant holders have piggyback registration rights requiring the inclusion of the shares of common stock issuable upon exercise of the Warrants (the “Warrant Shares”) in any registration statement filed by the Company. In addition, the Company has agreed to file a registration statement to register for resale all of the Warrant Shares and cause the registration statement to become effective by December 31, 2016 (the “Required Registration Statement”). If the Required Registration Statement is not declared effective by the required date, then the Company shall pay the holders liquidated damages in the aggregate amount of $5,000 per month, up to $50,000 in total, until both the Required Registration Statement has become effective and the Warrant Shares are listed. The Company incurred costs, primarily professional services, of approximately $2,900,000 related to the Loan Agreement. These costs were recorded as other assets in the Company’s consolidated balance sheet and are being amortized over the term of the Loan Agreement using the effective interest rate. Amortization expense totaled $939,498 and $262,820 for the years ended December 31, 2015 and 2014, respectively. The unamortized balance totaled $1,691,421 and $2,630,919 at December 31, 2015 and 2014, respectively.

Stockholders' Equity Note Disclosure [Text Block]	Note 11. Capital Stock The Company is authorized to issue 200,000,000 shares of common stock at a par value of $0.001. The holders of common stock are entitled to one vote per share. The holders of common stock are entitled to receive ratably such dividends, if any, as may be declared by the board of directors out of legally available funds. Upon liquidation, dissolution or winding-up, the holders of the Company’s common stock are entitled to share ratably in all assets that are legally available for distribution. The holders of the Company’s common stock have no preemptive, subscription, redemption or conversion rights. The rights, preferences and privileges of holders of the Company’s common stock are subject to, and may be adversely affected by, the rights of the holders of any series of preferred stock, which may be designated solely by action of the board of directors and issued in the future. At the Company’s annual meeting in August 2015, the shareholders approved an increase in the number of authorized shares of common stock from 95,000,000 to 200,000,000. In November 2010, the Company adopted a shareholder rights plan (the “Rights Plan”). Under the Rights Plan, the Company issued one preferred share purchase right for each share of the Company's common stock held by shareholders of record as of the close of business on November 24, 2010. In general, the rights will become exercisable if a person or group acquires 15% or more of the Company’s common stock or announces a tender offer or exchange offer for 15% or more of the Company’s common stock. Each holder of a right will be allowed to purchase one one-hundredth of a share of a newly created series of the Company’s preferred shares at an exercise price of $18.00. The rights will expire on November 8, 2020. The Company may redeem the rights for $0.001 each at any time until the tenth business day following public announcement that a person or group has acquired 15% or more of its outstanding common stock.

The amount of net shares issuable in connection with a cashless exercise will vary based on the exercise price of the option or warrant compared to the current market price of the Company’s common stock on the date of exercise. In February and March 2013, the Company completed an underwritten offering at $3.00 per share which resulted in gross proceeds of $33,000,000 and the issuance of 11,000,000 shares. The Company incurred costs of approximately $2,501,000 related to the offering. In February 2013, the Company issued 433,673 shares of common stock to Delos as part of the consideration paid for the acquisition. The fair value of the common stock issued was $1,071,172. In May 2013, the Company reduced the number of shares of common stock issued to Delos by 48,549 as a result of an adjustment to the purchase price. The reduction of common stock had a fair value of $119,916.

The total number of shares of common stock that remain available for issuance as of December 31, 2015 under the 2008 Directors Plan is 627,500 shares. The Company uses the Black-Scholes model to value options granted to employees, directors and consultants. Compensation expense, including the effect of forfeitures, is recognized over the period of service, generally the vesting period. The Company bases its forfeiture rate on past experience with a higher forfeiture rate applied in the initial years of the vesting period and lower rates applied in the later years of the vesting period. Stock-based compensation for the amortization of stock options granted under the Company’s stock option plans totaled $1,016,705, $953,470, and $1,182,523 for the years ended December 31, 2015, 2014, and 2013, respectively. Stock-based compensation is included in general and administrative expenses in the accompanying consolidated statements of operations. The unamortized amount of stock options expense was $585,688 as of December 31, 2015 which will be recognized over a weighted-average period of 0.8 year. The fair values of stock option grants were calculated on the dates of grant using the Black-Scholes option pricing model and the following weighted average assumptions: Years Ended December 31, 2015 2014 2013 Risk-free interest rate 1.5% - 1.7% 1.1% - 1.8% 0.8% - 1.9% Expected volatility 58% - 77% 47% - 60% 65% - 68% Expected life (in years) 4.1 - 4.2 4.1 - 5.3 5.0 - 6.5 Expected dividend yield 0% 0% 0% The risk-free interest rate was based on rates established by the Federal Reserve. The Company’s expected volatility was based upon the historical volatility for its common stock. The expected life of the Company’s options was determined using the simplified method as a result of limited historical data regarding the Company’s activity. Beginning in the fourth quarter of 2014, the Company began utilizing its historical data regarding the Company’s activity as it relates to the expected life of stock options. The dividend yield is based upon the fact that the Company has not historically paid dividends, and does not expect to pay dividends in the foreseeable future. The Company reviews its forfeiture rate annually to update its assumption for recent experience. Forfeiture rates used in 2015 ranged from 3% to 10%. During the first quarter of 2011, the Company issued 90,000 shares of restricted stock to two executives. The fair value of $354,600 was based on the closing market price of the Company’s common stock on the date of grant. The restricted stock vested over a three year period, of which 60,000 shares were vested and 30,000 shares of restricted stock were forfeited due to the resignation of an executive in November 2012. Stock-based compensation for restricted stock totaled $59,100 for the year ended December 31, 2013 and was also the period in which the restricted stock was fully vested. Option transactions under the stock option plans during the years ended December 31, 2015, 2014 and 2013 were as follows: Number of Options Weighted Average Exercise Price Outstanding as of January 1, 2013 3,916,045 $ 2.85 Granted during 2013 950,000 2.40 Exercised (420,159 ) 1.23 Forfeited /expired (390,870 ) 5.07 Outstanding as of December 31, 2013 4,055,016 2.70 Granted during 2014 737,073 1.42 Exercised (340,906 ) 0.74 Forfeited /expired (453,488 ) 1.78 Outstanding as of December 31, 2014 3,997,695 2.73 Granted during 2015 878,751 1.46 Exercised (426,530 ) 1.58 Forfeited /expired (109,874 ) 1.94 Outstanding as of December 31, 2015 4,340,042 $ 2.61 Exercisable as of December 31, 2015 3,372,743 $ 2.68 Grants under the stock option plans were as follows: For the Years Ended December 31, 2015 2014 2013 Annual grants to outside directors 200,000 200,000 200,000 Executive grants 231,251 172,073 125,000 Employee grants 447,500 315,000 625,000 Non-employee grants - 50,000 - Total 878,751 737,073 950,000 All options granted during the reporting period had a ten year term and were issued at an exercise price equal to the fair value on the date of grant.

ASC Topic 740 prescribes a comprehensive model for the financial statement recognition, measurement, presentation and disclosure of uncertain tax positions taken or expected to be taken in income tax returns. The guidance also provides direction on derecogntion, classification, interest and penalties, accounting in interim periods, disclosure and transition. As of December 31, 2015 and 2014, the Company has evaluated and concluded that there were no material uncertain tax positions requiring recognition in the Company’s financial statements. The Company’s policy is to classify assessments, if any, for tax related interest as interest expense and penalties as general and administrative expenses. No interest and penalties were recorded during the years ended December 31, 2015, 2014, and 2013. The Company does not expect its unrecognized tax benefit position to change during the next twelve months. NOL Limitations The Company’s utilization of net operating loss (“NOL”) carryforwards is subject to an annual limitation due to ownership changes that have occurred previously or that could occur in the future as provided in Section 382 of the Internal Revenue Code, as well as similar state provisions. Section 382 limits the utilization of NOLs when there is a greater than 50% change of ownership as determined under the regulations. Since its formation, the Company has raised capital through the issuance of capital stock and various convertible instruments which, combined with the purchasing shareholders’ subsequent disposition of these shares, has resulted in an ownership change as defined by Section 382, and also could result in an ownership change in the future upon subsequent disposition. As of December 31, 2015, 2014 and 2013, the Company had approximately $140,506,000, $108,398,000, and $84,417,000, respectively, of federal and state NOL carryovers. Federal NOLs will begin expiring in 2027. State NOLs began expiring in 2012. Valuation Allowance In assessing the realizability of deferred tax assets, the Company has considered whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. In making this determination, under the applicable financial reporting standards, the Company has considered the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies. Since both goodwill and the FCC licenses are considered to be assets with indefinite lives for financial reporting purposes, the related deferred tax liabilities cannot be used as a source of future taxable income for purposes of determining the need for a valuation allowance. Based upon this evaluation, a full valuation allowance has been recorded as of December 31, 2015 and 2014. The change in valuation allowance was $16,145,402 and $11,049,207, respectively, for the years ended December 31, 2015 and 2014 of which $8,511,042 and $6,623,656, respectively, pertains to discontinued operations.

Fair Value Disclosures [Text Block]	Note 15. Fair Value Measurement Valuation Hierarchy The FASB’s accounting standard for fair value measurements establishes a valuation hierarchy for disclosure of the inputs to valuation used to measure fair value. This hierarchy prioritizes the inputs into three broad levels. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable inputs based on the Company’s own assumptions used to measure assets and liabilities at fair value. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. Cash and cash equivalents are measured at fair value using quoted market prices and are classified within Level 1 of the valuation hierarchy. The carrying amounts of accounts receivable, accounts payable and accrued liabilities approximate their fair value due to their short maturities. The carrying value of the Company’s long-term debt is carried at cost as the related interest rate is at terms that approximate rates currently available to the Company. There were no changes in the valuation techniques during the year ended December 31, 2015. Total Carrying Value Quoted prices in active markets (Level 1) Significant other observable inputs (Level 2) Significant unobservable inputs (Level 3) December 31, 2015 $ 15,116,531 $ 15,116,531 $ - $ - December 31, 2014 $ 38,027,509 $ 38,027,509 $ - $ -

Subsequent Events On March 9, 2016, the Company completed a sale and transfer of certain assets pursuant to an Asset Purchase Agreement (the "Agreement") with a large cable company (the "Buyer"). Under the terms of the Agreement, the Buyer assumed certain rooftop leases and acquired ownership of and the right to operate the WiFi access point and related equipment associated with such leases. The Company retained ownership of all backhaul and related equipment, and the parties entered into a three year agreement under which the Company will provide backhaul services to the Buyer. The previous access agreement between the parties was terminated. The net effect of the Buyer (i) assuming certain rooftop leases, (ii) entering into a backhaul services agreement, and (iii) terminating the access agreement is projected to result in a net reduction in cash requirements of approximately $6 million annually.

Expenditures for maintenance and repairs which do not extend the useful life of the assets are charged to expense as incurred. Gains or losses on disposals of property and equipment are reflected in general and administrative expenses in the Company’s consolidated statements of operations.
Goodwill and Intangible Assets, Intangible Assets, Indefinite-Lived, Policy [Policy Text Block]	FCC Licenses.
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]	Long-Lived Assets The FASB’s guidance on asset retirement obligations addresses financial accounting and reporting for obligations associated with the retirement of tangible long-lived assets and the associated costs. This guidance requires the recognition of an asset retirement obligation and an associated asset retirement cost when there is a legal obligation associated with the retirement of tangible long-lived assets. The Company’s network equipment is installed on both buildings in which the Company has a lease agreement (“Company Locations”) and at customer locations. In both instances, the installation and removal of the Company’s equipment is not complicated and does not require structural changes to the building where the equipment is installed. Costs associated with the removal of the Company’s equipment at company or customer locations are not material, and accordingly, the Company has determined that it does not presently have asset retirement obligations under the FASB’s accounting guidance.
Business Combinations Policy [Policy Text Block]	Business Acquisitions The highest level of judgment and estimation involved in accounting for business acquisitions relates to determining the fair value of the customer relationships and network assets acquired. In each of the five acquisitions completed over the past four years, the highest asset value has been allocated to the customer relationships acquired. Determining the fair value of customer relationships involves judgments and estimates regarding how long the customers will continue to contract services with the Company. During the course of completing five acquisitions, the Company has developed a database of historical experience from prior acquisitions to assist in preparing future estimates of cash flows. Similarly, the Company has used its historical experience in building networks to prepare estimates regarding the fair value of the network assets that it acquires.

New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Pronouncements. In May 2014, the FASB issued ASU No. 2014-09 (“ASU 2014-09”), “Revenue from Contracts with Customers,” which requires an entity to recognize revenue representing the transfer of promised goods or services to customers in an amount that reflects the consideration which the company expects to receive in exchange for those goods or services. ASU 2014-09 is intended to establish principles for reporting useful information to users of financial statements about the nature, amount, timing and uncertainty of revenues and cash flows arising from the entity’s contracts with customers. ASU 2014-09 will replace most existing revenue recognition guidance in Generally Accepted Accounting Principles (“GAAP”) when it becomes effective. The new standard is effective for the Company on January 1, 2018. Early application is only permitted as of January 1, 2017. The Company is currently evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. In June 2014, the FASB issued ASU No. 2014-12 (“ASU 2014-12”), “Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period,” which requires a performance target that affects vesting, and that could be achieved after the requisite service period, be treated as a performance condition. ASU 2014-12 states that the performance target should not be reflected in estimating the grant date fair value of the award. ASU 2014-12 clarifies that compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the periods for which the requisite service has already been rendered. The new standard is effective for the Company on January 1, 2016. The Company does not expect adoption of ASU 2014-12 to have a significant impact on its consolidated financial statements. In August 2014, the FASB issued ASU No. 2014–15 (“ASU 2014-15”), “Presentation of Financial Statements – Going Concern.” ASU 2014-15 provides GAAP guidance on management’s responsibility in evaluating whether there is substantial doubt about a company’s ability to continue as a going concern and about related footnote disclosures. For each reporting period, management will be required to evaluate whether there are conditions or events that raise substantial doubt about a company’s ability to continue as a going concern within one year from the date the financial statements are issued. The new standard is effective for the Company on January 1, 2017. The Company does not expect the adoption of ASU 2014–15 to have a significant impact on its consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-03 (“ASU 2015-03”), “Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs.” ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability, consistent with debt discounts, instead of being presented as an asset. ASU 2015-03 is effective for the Company on January 1, 2016. Once adopted, entities are required to apply the new guidance retrospectively to all prior periods presented. The retrospective application represents a change in accounting principle. Early adoption is permitted for financial statements that have not been previously issued. The Company is currently evaluating the effect that ASU 2015-03 will have on its consolidated financial statements and related disclosures. In May 2015, the FASB issued ASU No. 2015-07 (“2015-07”), “Fair Value Measurement.” ASU 2015-07 removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient. The amendments also remove the requirement to make certain disclosures for all investments that are eligible to be measured at fair value using the net asset value per share practical expedient. ASU 2015-07 is effective for the Company on January 1, 2016. Early adoption is permitted. The Company does not expect the adoption of ASU 2015–07 to have a significant impact on its consolidated financial statements. In September 2015, the FASB issued ASU No. 2015-16 (“ASU 2015-16”), “Business Combinations (Topic 805), Simplifying the Accounting for Measurement-Period Adjustments”. The update requires that the acquirer in a business combination recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined (not retrospectively as with prior guidance). Additionally, the acquirer must record in the same period’s financial statements the effect on earnings of changes in depreciation, amortization or other income effects as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the time of acquisition. The acquiring entity is required to disclose, on the face of the financial statements or in the footnotes to the financial statements, the portion of the amount recorded in current period earnings, by financial statement line item, that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. ASU 2015-16 is effective for the Company on January 1, 2016. The adoption of this standard is not expected to have a material impact on its consolidated financial statements. In September 2015, the FASB issued ASU No. 2015-16 (“ASU 2015-16”), “Business Combinations (Topic 805), Simplifying the Accounting for Measurement-Period Adjustments”. The update requires that the acquirer in a business combination recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined (not retrospectively as with prior guidance). Additionally, the acquirer must record in the same period’s financial statements the effect on earnings of changes in depreciation, amortization or other income effects as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the time of acquisition. The acquiring entity is required to disclose, on the face of the financial statements or in the footnotes to the financial statements, the portion of the amount recorded in current period earnings, by financial statement line item, that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. ASU 2015-16 is effective for the Company on January 1, 2016. The adoption of this standard is not expected to have a material impact on its consolidated financial statements. In November 2015, the FASB has issued an update to ASU No. 2015-17 (“ASU 2015-17”) “Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes.” The update requires a company to classify all deferred tax assets and liabilities as noncurrent. The update of ASU 2015-17 is effective for the Company on January 1, 2018. The Company does not expect the adoption of the update of ASU 2015–17 to have a significant impact on its consolidated financial statements. In January 2016, the FASB issued ASU No. 2016-01 (“ASU 2016-01”), “Financial Instruments – Overall (Subtopic 825-10)”. ASU 2016-01 updates certain aspects of recognition, measurement, presentation and disclosure of financial instruments. The new guidance is effective for us on January 1, 2018. The Company does not expect the adoption of ASU 2016–01 to have a significant impact on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02 (“ASU 2016-02), “Leases (Topic 842).” ASU 2016-02 requires a lessee to recognize a lease liability for the obligation to make lease payments and a right-to-use asset for the right to use the underlying asset for the lease term. ASU 2016-02 is effective for the Company on January 1, 2019. Early adoption is permitted. The Company is currently evaluating the effect that ASU 2016-02 will have on its consolidated financial statements.
