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 regulated and unregulated 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. 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 Wi-Fi access point and related equipment associated with such leases. The Company retained ownership of all backhaul and related equipment, and the parties entered into an agreement under which the Company provides backhaul services to the Buyer. The agreement is for a three year period with two, one year renewals and is cancellable by the Buyer on sixty days’ notice. During the first quarter of 2016, the Company determined that it would not be able to sell the remainder of the New York City network, and accordingly, all remaining assets were redeployed into the fixed wireless network or written off. The operating results and cash flows for Hetnets have been reclassified and presented as discontinued operating results for all periods presented in these condensed consolidated financial statements.

Liquidity and Management Plans [Text Block]	Note 2. Liquidity and Management Plans The accompanying condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. As of March 31, 2016, the Company had cash and cash equivalents of approximately $9.6 million and working capital of approximately $3.8 million. The Company incurred significant operating losses since inception and continues to generate losses from operations and as of March 31, 2016, the Company has an accumulated deficit of $163.2 million. These matters raise substantial doubt about the Company’s ability to continue as a going concern. The condensed consolidated financial statements do not include any adjustments relating to the recoverability and classification of asset amounts or the classification of liabilities that might be necessary should the Company be unable to continue as a going concern. Historically, the Company has financed its operation through private and public placement of equity securities, as well as debt financing 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. The Company intends to raise additional capital, either through debt or equity financings or through the potential sale of the Company’s assets in order to achieve its business plan objectives. Management believes that it can be successful in obtaining additional capital; however, no assurance can be provided that the Company will be able to do so. There is no assurance that any funds raised will be sufficient to enable the Company to attain profitable operations or continue as a going concern. To the extent that the Company is unsuccessful, the Company may need to curtail or cease its operations and implement a plan to extend payables or reduce overhead until sufficient additional capital is raised to support further operations. There can be no assurance that such a plan will be successful.

Disposal Groups, Including Discontinued Operations, Disclosure [Text Block]	Note 4 . Discontinued Operations During the fourth quarter of 2015, the Company determined to exit the business conducted by Hetnets 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. 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 Wi-Fi access point and related equipment associated with such leases. The Company retained ownership of all backhaul and related equipment, and the parties entered into an agreement under which the Company provides backhaul services to the Buyer. The agreement is for a three year period with two, one year renewals and is cancellable by the Buyer on sixty days’ notice. The Company recognized a gain of $1,177,742 as the net present value of the backhaul agreement of $3,837,783, which has been recorded as an intangible asset, exceeded the net book value of the network assets transferred to the Buyer which totaled $2,660,041. - The Company has determined that it will not be able to sell the remaining network locations in New York City. As a result, the Company recognized charges totaling $1,585,319 in the first quarter of 2016 which included $453,403 representing the estimated cost to settle lease obligations, $528,364 to write off network assets which could not be redeployed into the fixed wireless network, $110,500 related to security deposits which are not expected to be recovered, and $493,052 related to the accelerated expensing of deferred acquisition costs. These costs were partially offset by a $1,244,284 reduction in the accrual for terminated lease obligations that was recorded in the fourth quarter of 2015. This reduction reflects the outcome of settlements negotiated in the first quarter of 2016 with certain landlords. The operating results and cash flows for Hetnets have been reclassified and presented as discontinued operations in these condensed consolidated financial statements for all periods presented.

Notes to Financial Statements
Debt Disclosure [Text Block]	Note 9. 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 $74,063 and $91,765 in connection with the amortization of this discount for the three months ended March 31, 2016 and 2015, respectively. The unamortized balance totaled $539,673 at March 31, 2016 and $613,736 at December 31, 2015. The Note 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 $743,144 and $705,911 of interest, and accrued $371,572 and $352,956 of PIK interest for the three months ended March 31, 2016 and 2015, respectively. As of March 31, 2016, 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.

Disclosure of Compensation Related Costs, Share-based Payments [Text Block]	Note 10 . Stock Options and Warrants Stock Options The Company uses the Black-Scholes option pricing model to value options issued to employees, directors and consultants. Compensation expense, including the estimated effect of forfeitures, is recognized over the period of service, generally the vesting period. Stock compensation expense and the weighted average assumptions used to calculate the fair values of stock options granted during the periods indicated were as follows: Three Months Ended March 31 , 2016 2015 Risk-free interest rate 1.2% - 1.4% - Expected volatility 77.6% - 82.1% - Expected life (in years) 4.2 - Expected dividend yield - - Weighted average per share grant date fair value $ 0.14 $ - Stock-based compensation $ 296,385 $ 209,209 The risk-free interest rate was based on rates established by the Federal Reserve. The expected volatility was based upon the historical volatility for the Company’s common stock. The Company utilized historical data to determine the expected life of stock options. The dividend yield reflected the fact that the Company has not historically paid dividends, and does not expect to pay dividends in the foreseeable future. Stock-based compensation is included in general and administrative expenses in the accompanying condensed consolidated statements of operations. The unamortized amount of stock options expense totaled $391,761 as of March 31, 2016 which will be recognized over a weighted-average period of 0.8 years. Option transactions under the stock option plans during the three months ended March 31, 2016 were as follows: Number Weighted Average Exercise Price Outstanding as of January 1, 2016 4,340,042 $ 2.61 Granted during 2016 825,000 0.24 Exercised - - Cancelled /expired 89,500 1.48 Outstanding as of March 31, 2016 5,075,542 $ 2.24 Exercisable as of March 31, 2016 3,946,080 $ 2.57 - In February 2016, the Company granted a consultant 100,000 options with an exercise price of $0.20 which vested immediately. In March 2016, the Company granted its newly appointed interim Chief Executive Officer 100,000 options with an exercise price of $0.25 and 25,000 options with an exercise price of $0.12 both of which vested immediately, and its newly appointed Chief Operating Officer 600,000 options with an exercise price of $0.25 which vest quarterly over a two year period. The aggregate fair value of the options granted was $116,210 for the three months ended March 31, 2016. Cancellations for the three months ended March 31, 2016 related to employee terminations. The weighted average remaining contractual life of the outstanding options as of March 31, 2016 was 7 .0 years. There was no aggregate intrinsic value associated with the options outstanding and exercisable as of March 31, 2016. The closing price of the Company’s common stock at March 31, 2016 was $0.12 per share. Stock Warrants There were 4,050,000 warrants outstanding and exercisable at March 31, 2016 with a weighted average exercise price of $1.31 per share. The weighted average remaining contractual life of the warrants was 5.4 years. No stock warrants were issued, exercised, expired or cancelled during the three months ended March 31, 2016. The aggregate intrinsic value associated with the warrants outstanding and exercisable as of March 31, 2016 was $132,000. Cashless Exercises The number of shares issuable upon the exercise of an option or a warrant will be lower if a holder exercises on a cashless basis. Under a cashless exercise, the holder uses a portion of the shares that would otherwise be issuable upon exercise, rather than cash, as consideration for the exercise. 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 market price of the Company’s common stock on the date of exercise.

Fair Value Disclosures [Text Block]	Note 12. Fair Value Measurement Valuation Hierarchy The accounting standard of the FASB 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. The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their fair value due to their short maturities. There were no changes in the valuation techniques during the three months ended March 31, 2016.

Earnings Per Share [Text Block]	Note 13. Net Loss Per Common Share Basic and diluted net loss per share has been calculated by dividing net loss by the weighted average number of common shares outstanding during the period and the inclusion of 1,200,000 warrants to purchase shares of common stock at an exercise price of $0.01. For the three ended March 31, 2016 and 2015, the following common stock equivalents were excluded from the computation of diluted net loss per common share because they were anti-dilutive. The exercise or issuance of these common stock equivalents outstanding at March 31, 2016 and 2015 would dilute earnings per share if the Company becomes profitable in the future.
