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 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, Going Concern 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 September 30, 2016, the Company had cash and cash equivalents of approximately $13 million and working capital of approximately $7.6 million. The Company incurred significant operating losses since inception and continues to generate losses from operations and as of September 30, 2016, the Company has an accumulated deficit of $173 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. During the nine months ended September 30, 2016, the Company has raised net proceeds of approximately $6.8 million through the placement of its equity securities. In addition, the Company has monitored and reduced certain of its operating costs over the course of the year. 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.

The Company’s accounting policies are described in the Notes to Consolidated Financial Statements in its Annual Report on Form 10-K for the year ended December 31, 2015, and updated, as necessary, in this Quarterly Report on Form 10-Q.

Segments Recent Accounting Pronouncements. In April 2016, the FASB issued ASU No. 2016-10 (“ASU 2016-10”), “Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing.” ASU 2016-10 will affect all entities that enter into contracts with customers to transfer goods or services (that are an output of the entity’s ordinary activities) in exchange for consideration. The amendments in this update affect the guidance in ASU 2014-09 which is not yet effective, the amendments in this update clarify the following two aspects of Topic 606: identifying performance obligations and the licensing implementation guidance, while retaining the related principles for those areas. The effective date and transition requirements for the amendments in this update are effective in the annual period ending December 31, 2017, including interim periods within that annual period. The Company is currently evaluating the effect that ASU 2016-10 will have on the Company’s consolidated financial position and results of operations. In May 2016, the FASB issued ASU No. 2016-12 (“ASU 2016-12”), “Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients.” ASU 2016-12 will affect all entities that enter into contracts with customers to transfer goods or services (that are an output of the entity’s ordinary activities) in exchange for consideration. The amendments in this update affect the guidance in ASU 2014-09 which is not yet effective, the amendments in this update affect narrow aspects of Topic 606 including among others: assessing collectability criterion, noncash consideration, and presentation of sales taxes and other similar taxes collected from customers. The effective date and transition requirements for the amendments in this update are the same as the effective date and transition requirements for ASU 2016-10. The Company is currently evaluating the effect that ASU 2016-12 will have on the Company’s consolidated financial position and results of operations. In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments” (“ASU 2016-15”). ASU 2016-15 is intended to address how certain cash receipts and cash payments are presented and classified in the statement of cash flows. This update addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. The amendments are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company is currently evaluating the effect that ASU 2016-15 will have on the Company’s consolidated financial position and results of operations. Subsequent Events

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. In connection with the Agreement, the Company transferred to the Buyer a net book value of network assets aggregating $2,660,041 in exchange for the backhaul agreement valued at $3,837,783. The backhaul agreement has been recorded as an intangible asset in the accompanying condensed consolidated balance sheet. As a result, during the first quarter of 2016, the Company recognized a gain of $1,177,742 in its discontinued operations. 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. 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.

Stockholders' Equity Note Disclosure [Text Block]	Note 10. Capital Stock In February 2016, the Company issued 5,000 shares of our common stock to a third party for investor relation services with a fair value of $20,000. The fair value of the common stock was expensed immediately, pursuant to the terms of the agreement, and recognized in general and administrative expenses in the Company’s condensed consolidated statements of operations. On June 17, 2016, the Company entered into securities purchase agreements with certain accredited investors pursuant to which the Company raised $2,280,000 in a registered direct offering for a total of 750,000 shares (a “Share”) of the Company’s common stock, par value $0.001 per share (the “Common Stock”). Each Share was sold as a unit (each, a “Unit”, and collectively, the “Units”) at a purchase price of $3.04 per Unit, with each Unit consisting of one Share and an unregistered warrant to purchase one share of Common Stock (collectively, the “Warrants”). The Common Stock and the Warrants are immediately separable and were issued separately. Expenses associated with this direct offering totaled $43,750 resulting in net proceeds to the Company of $2,236,250. Such net proceeds were allocated to the shares and the warrants issued in the amounts of $1,677,188 and $559,063, respectively, in proportion to their relative fair value on the date of issuance. On July 5, 2016, the Company filed a certificate of amendment (the “Amendment”) to its Certificate of Incorporation with the Secretary of State of the State of Delaware in order to effectuate a reverse stock split of the Company’s issued and outstanding common stock, par value $0.001 per share, on a one for twenty basis (the “Reverse Stock Split”). As a result of the Reverse Stock Split, every twenty shares of the Company’s pre-reverse split common stock will be combined and reclassified into one share of the Company’s common stock. No fractional shares of common stock will be issued. Stockholders who otherwise would be entitled to a fractional share shall receive the next higher number of whole shares. The par value and other terms of Company’s common stock were not affected by the Reverse Stock Split. The Reverse Stock Split was effective July 7, 2016. On July 6, 2016, the Company entered into a securities purchase agreement (the “Purchase Agreement”) with an accredited investor pursuant to which the Company raised $1,250,000 in a private placement offering 892,857 units of the Company’s securities (the “Units”) at a price of $1.40 per Unit. As adjusted for the Reverse Stock Split, each Unit consists of (i) one share of Series B Convertible Preferred Stock, par value $0.001 per share (the “Preferred Stock”), with each share of Preferred Stock convertible into one half of a share of common stock, and (ii) one fourth of a warrant (a “Warrant”), with each Warrant exercisable into common stock at an exercise price equal to $3.00 per share of common stock. The transaction closed on July 7, 2016. On July 21 and 26, 2016, the holder converted all 892,857 shares of the preferred stock into 446,429 shares of common stock. On July 7, 2016, the Company also entered into a First Amendment (the “Amendment”) to those certain Securities Purchase Agreements, dated June 17, 2016 (the “June Purchase Agreements”), pursuant to which the Company agreed to amend the June Purchase Agreements entered into by and between certain investors and the Company. Pursuant to the terms of the Amendment and as adjusted for the Reverse Stock Split, the June Warrants were amended and restated to change the exercise price of the warrants to $3.80 from $5.00 and to include a mandatory exercise right of the Company to force exercise of the June Warrants if the Company’s common stock trades at or above $7.60 for any ten consecutive trading days out of a thirty consecutive trading day period (subject to certain equity conditions, a 9.99% beneficial ownership limitation and applicable NASDAQ shareholder approval rules, if any). All other terms of the June Warrants, including cash exercise if registered for resale within 90 days of closing, remain unchanged. On July 19, 2016, the Company issued 125,000 shares of our common stock to a third party for consulting services with a fair value of $385,000. The fair value of the common stock was expensed immediately, pursuant to the terms of the agreement, and recognized in general and administrative expenses in the Company’s condensed consolidated statements of operations. In September 2016, the Company issued 52,966 shares of our common stock with a fair value of $68,856 and 10,000 shares of our common stock with a fair value of $14,800 to third parties for investor relation services. The fair value of the common stock was expensed immediately pursuant to the terms of the agreements, and recognized in general and administrative expenses in the Company’s condensed consolidated statements of operations. On September 12, 2016, the Company entered into a series of Exchange Agreements whereby warrants issued on June 17 and July 7, 2016 for the purchase of up to 750,000 and 223,214, respectively, were exchanged for 680,000 shares of newly issued Series C Convertible Preferred Stock ("Series C Preferred"). Such Series C Preferred Stock is convertible for a like number of common shares at any time at the option of the holders subject to a 9.99% beneficial ownership limitation and applicable NASDAQ shareholder approval rules, if any. On various dates from October 10 through October 18, 2016, all of the holders of the Series C Preferred elected to exercise their conversion privileges and the Company issued 680,000 common shares. On September 16, 2016, the Company completed an underwritten offering at $1.35 per share which resulted in gross proceeds of $4,000,000 and the issuance of 2,962,963 shares. The Company incurred costs of approximately $628,000 related to the offering. The Company granted the underwriter an option for a period of up to 45 days from the date of the prospectus to purchase up to an aggregate of 444,444 shares of the Company's common stock at $1.35 per share to cover overallotments.

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 $1,003,595 as of September 30, 2016 which will be recognized over a weighted-average period of 2.4 years.

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 dividend yield reflected the fact that the Company has not historically paid dividends, and does not expect to pay dividends in the foreseeable future. In connection with the July 7, 2016 offering, the Company issued warrants to purchase 223,214 shares of common stock.

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 dividend yield reflected the fact that the Company has not historically paid dividends, and does not expect to pay dividends in the foreseeable future. As the consultant had yet to commence providing services as of September 30, 2016, the value of those warrants had yet to be recorded as additional paid-in capital nor had any expense been recorded during the three month period then ended. The weighted average remaining contractual life of the warrants was five years.

Fair Value Disclosures [Text Block]	Note 13. 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 and nine months ended September 30, 2016.

Subsequent Events [Text Block]	Note 16. Subsequent Events On various dates from October 10 through October 18, 2016 and as disclosed in Note 10, the holders of 680,000 shares of Series C Convertible Preferred Stock elected to exercise their conversion privileges and the Company issued 680,000 common shares. On October 25, 2016 and as disclosed in Note 10, the underwriter which assisted the Company in the offering of September 16, 2016 exercised an over-allotment option and purchased 444,444 common shares at $1.35 per share which resulted in gross proceeds to the Company of $600,000. On November 8, 2016, the Company entered into a series of agreements wherein $5 million of the Company’s senior secured debt due to Melody Business Financing, LLC (“Melody”) was canceled and the Company simultaneously issued 1,000 shares of Series D Convertible Preferred Stock ("Series D Preferred") and warrants to purchase 4.0 million shares of common stock (the “Warrants”) at an exercise price of $1.15 per share. Those 1,000 shares of Series D Convertible Preferred Stock are convertible into 8,540,373 shares of the Company's common stock at the option of the holders. The detail terms of the Series D Preferred and the Warrants are described in the paragraphs below and are subject to adjustment as indicated. The Warrants expire five years from the date of issuance and are exercisable six months after the date of issuance. The Warrants may be exercised on a cashless basis if there is no effective registration statement registering the shares of common stock underlying the Warrants for resale within 90 days of issuance. Otherwise, the Warrants may be exercised for cash. The exercise price shall be reduced to $1.01 per share upon the failure to timely register for resale the shares of common stock underlying the Warrants. The Warrants also provide for certain rights upon fundamental transactions and adjustments to the exercise price of the Warrants based on stock dividends, stock splits and similar corporate actions. The Company is prohibited from effecting the exercise of a holder’s Warrant to the extent that, as a result of such exercise, such holder would beneficially own more than 9.99% of the number of shares of Common Stock outstanding immediately after giving effect to the issuance of shares of common stock upon exercise of such Warrant. Also on that same date, the Company entered into a registration rights agreement pursuant to which it agreed to register for resale 150% of the shares of common stock underlying the Series D Convertible Preferred Stock and Warrants.

In April 2016, the FASB issued ASU No. 2016-10 (“ASU 2016-10”), “Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing.” ASU 2016-10 will affect all entities that enter into contracts with customers to transfer goods or services (that are an output of the entity’s ordinary activities) in exchange for consideration. The amendments in this update affect the guidance in ASU 2014-09 which is not yet effective, the amendments in this update clarify the following two aspects of Topic 606: identifying performance obligations and the licensing implementation guidance, while retaining the related principles for those areas. The effective date and transition requirements for the amendments in this update are effective in the annual period ending December 31, 2017, including interim periods within that annual period. The Company is currently evaluating the effect that ASU 2016-10 will have on the Company’s consolidated financial position and results of operations. In May 2016, the FASB issued ASU No. 2016-12 (“ASU 2016-12”), “Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients.” ASU 2016-12 will affect all entities that enter into contracts with customers to transfer goods or services (that are an output of the entity’s ordinary activities) in exchange for consideration. The amendments in this update affect the guidance in ASU 2014-09 which is not yet effective, the amendments in this update affect narrow aspects of Topic 606 including among others: assessing collectability criterion, noncash consideration, and presentation of sales taxes and other similar taxes collected from customers. The effective date and transition requirements for the amendments in this update are the same as the effective date and transition requirements for ASU 2016-10. The Company is currently evaluating the effect that ASU 2016-12 will have on the Company’s consolidated financial position and results of operations. In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments” (“ASU 2016-15”). ASU 2016-15 is intended to address how certain cash receipts and cash payments are presented and classified in the statement of cash flows. This update addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. The amendments are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company is currently evaluating the effect that ASU 2016-15 will have on the Company’s consolidated financial position and results of operations.
