TOWERSTREAM CORPORATION AND SUBSIDIARIES

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

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 (“VPNs”), disaster recovery, bundled data and video services. The Company provides services to approximately 3,600 business customers in New York City, Boston, Chicago, Los Angeles, San Francisco, Seattle, Miami, Dallas-Fort Worth, Houston, Philadelphia, Nashville, Las Vegas-Reno and Providence-Newport. The Company's “fixed wireless business” has grown both organically and through the acquisition of five other fixed wireless broadband providers in various markets.

Since 2010, the Company has been exploring opportunities to leverage its fixed wireless network in urban markets to provide other wireless technology solutions and services. Over the past few years, a significant increase in mobile data generated by smartphones, tablets and other devices has placed tremendous demand on the networks of the carriers. This has caused the carriers to explore a wide range of solutions including (i) acquiring additional spectrum, (ii) employing Wi-Fi to offload data traffic and (iii) utilizing small cell technologies to increase capacity in dense urban areas. During this period, the Company has incurred various costs related to identifying possible new solutions and services. These costs included (a) rent payments under lease agreements which provide the right to install wireless technology equipment on street level rooftops, and (b) construction of a carrier-class network to offload data traffic. The Company has entered into the lease agreements and commenced these capital projects for the purpose of securing capacity that it believes is needed to maintain its competitive position in the wireless industry. The Company believes that the wireless communications industry is experiencing a fundamental shift from its current, macro-cellular architecture to hyper-densified Small Cell architecture where existing cell sites will be supplemented by many smaller base stations operating near street level. The Company also believes that Wi-Fi will be an integral component of Small Cell architecture.

In January 2013, the Company incorporated a wholly-owned subsidiary, Hetnets Tower Corporation (“Hetnets”). The Company plans to transfer certain assets to Hetnets to support the operation of a shared wireless infrastructure business. Hetnets plans to generate rental income from four separate sources including (i) rental of space on street level rooftops for the installation of customer owned Small Cells which includes Wi-Fi antennae, DAS, and Metro and Pico cells, (ii) rental of a channel on Hetnets’ Wi-Fi network for the offloading of mobile data, (iii) rental of cabinets, switch ports, interconnection services, including backhaul or transport, and (iv) rental of power and power backup. The Company refers to the activities of Hetnets as its "shared wireless infrastructure business."

Note 2.    Summary of Significant Accounting Policies

Basis of Presentation. The condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial statements and with Form 10-Q and Article 10 of Regulation S-X of the United States Securities and Exchange Commission (“SEC”). Accordingly, they do not contain all information and footnotes required by accounting principles generally accepted in the United States of America for annual financial statements. The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. In the opinion of the Company’s management, the accompanying unaudited condensed consolidated financial statements contain all the adjustments necessary (consisting only of normal recurring accruals) to present the financial position of the Company as of March 31, 2013 and the results of operations and cash flows for the periods presented. The results of operations for the three months ended March 31, 2013 are not necessarily indicative of the operating results for the full fiscal year for any future period.

These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. 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, 2012, and updated, as necessary, in this Quarterly Report on Form 10-Q.

Use of Estimates.    The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the amounts of revenues and expenses. Actual results could differ from those estimates.

Cash and Cash Equivalents.    The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents.

Concentration of Credit Risk.    Financial instruments that potentially subject the Company to significant concentrations of credit risk consist of cash and cash equivalents. At times, our cash and cash equivalents may be uninsured or in deposit accounts that exceed the Federal Deposit Insurance Corporation (“FDIC”) insurance limits. As of March 31, 2013, the Company had cash and cash equivalent balances of approximately $32,313,000 in excess of the federally insured limit of $250,000.

The Company also had approximately $7,766,000 invested in three institutional money market funds. These funds are protected under the Securities Investor Protection Corporation, a nonprofit membership corporation which provides limited coverage up to $500,000.

Accounts Receivable. Accounts receivable are stated at cost less an allowance for doubtful accounts which reflects the Company’s estimate of balances that will be not collected. The allowance is based on the history of past write-offs, the aging of balances, collections experience and current credit conditions. Additions include provisions for doubtful accounts and deductions include customer write-offs. Changes in the allowance for doubtful accounts were as follows:

	Three Months Ended March 31,
	2013			2012
Beginning of period	$	190,109		$	262,525
Additions		-			30,000
Deductions		(46,672	)		(49,537	)
End of period	$	143,437		$	242,988

TOWERSTREAM CORPORATION AND SUBSIDIARIES

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Business Acquisitions. Business combinations are accounted for using the acquisition method. The cost of an acquisition is measured as the fair value of the consideration transferred on the acquisition date.  When the Company acquires a business, it assesses the acquired assets and liabilities assumed for the appropriate classification and designation in accordance with the contractual terms, economic circumstances and pertinent conditions at the acquisition date. The excess of the total consideration transferred over the net identifiable assets acquired and liabilities assumed is recognized as goodwill.  If this consideration is lower than the fair value of the identifiable net assets acquired, the difference is recognized as a gain on business acquisition. Acquisition costs are expensed and included in general and administrative expenses in our condensed consolidated statements of operations.

Revenue Recognition. The Company normally enters into contractual agreements with its customers for periods ranging between one to three years. The Company recognizes the total revenue provided under a contract ratably over the contract period, including any periods under which the Company has agreed to provide services at no cost. The Company recognizes revenue when (i) persuasive evidence of an arrangement exists, (ii) delivery or installation has been completed, (iii) the customer accepts and verifies receipt, and (iv) collectability is reasonably assured.

Deferred Revenues. Customers are billed monthly in advance. Deferred revenues are recognized for that portion of monthly charges not yet earned as of the end of the reporting period. Deferred revenues are also recognized for certain customers who pay for their services in advance.

Goodwill. Goodwill represents the excess of the purchase price over the estimated fair value of identifiable net assets acquired in an acquisition. Goodwill is not amortized but rather is reviewed annually for impairment, or whenever events or circumstances indicate that the carrying value may not be recoverable. The Company initially performs a qualitative assessment of goodwill which considers macro-economic conditions, industry and market trends, and the current and projected financial performance of the reporting unit.  No further analysis is required if it is determined that there is a less than 50 percent likelihood that the carrying value is greater than the fair value. 

Reclassifications.    Certain accounts in the prior years’ consolidated financial statements have been reclassified for comparative purposes to conform to the presentation in the current year consolidated financial statements. These reclassifications have no effect on the previously reported net loss.

Subsequent Events. Subsequent events have been evaluated through the date of this filing.

Note 3.    Business Acquisitions

Delos Internet

In February 2013, the Company completed the acquisition of Delos Internet (“Delos”). The Company obtained full control of Delos in the acquisition. The Company has determined that the acquisition of Delos 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:

TOWERSTREAM CORPORATION AND SUBSIDIARIES

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

The Company recognized a gain on business acquisition of $941,457 which is included in other income (expense) in the Company’s condensed consolidated statements of operations for the three months ended March 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.

The results of operations of Delos have been included in the Company’s condensed consolidated statements of operations since the completion of the acquisition in February 2013. Revenues generated from customers acquired from Delos totaled approximately $56,000 for the three months ended March 31, 2013.

During the three months ended March 31, 2013, the Company incurred approximately $58,000 of third-party costs in connection with the Delos acquisition. These expenses are included in the general and administrative expenses in the Company’s condensed consolidated statements of operations for the three months ended March 31, 2013.

Note 7.    Other Liabilities

Other liabilities consist of the following:

	March 31, 2013		December 31, 2012
Current
Deferred rent	$	57,880	$	86,820
Deferred acquisition payments		143,848		148,198
Total	$	201,728	$	235,018

Deferred taxes		244,274		244,274
Total	$	266,696	$	301,101

The gross balance of deferred acquisition payments totaled $232,826 at March 31, 2013 and is payable in monthly installments of $16,630 through May 2014. The net present value was calculated at a discount rate of 12%.

Note 8. Capital Stock

In February 2013, the Company completed an underwritten offering which raised gross proceeds of $30,000,000 in connection with the sale of 10,000,000 shares at $3.00 per share. In March 2013, the Company raised additional gross proceeds of $3,000,000 in connection with the sale of 1,000,000 shares at $3.00 per share related to the exercise of the over-allotment option by the underwriters. The Company incurred costs of approximately $2,499,000 related to the underwritten offering.

Note 9. Stock-Based Compensation

The Company uses the Black-Scholes option pricing 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. Stock-based compensation totaled $378,205 and $490,325 for the three months ended March 31, 2013 and 2012, respectively. 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 $1,322,797 as of March 31, 2013 which will be recognized over a weighted-average period of 2.0 years.

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:

	Three Months Ended March 31,
	2013			2012
Risk-free interest rate		0.8	%		0.7%-1.0 %
Expected volatility		68	%		65% - 73%
Expected life (in years)		5			5
Expected dividend yield		-			–
Weighted average per share grant date fair value	$	1.46		$	2.18

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. 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.

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 vests over a three year period, of which 45,000 shares were vested as of March 31, 2013. Stock-based compensation for restricted stock totaled $14,775 and $29,550 for the three months ended March 31, 2013 and 2012, respectively. Unrecognized compensation cost of $44,325 at March 31, 2013 will be recognized ratably through December 2013. As of March 31, 2013, 15,000 shares of restricted stock remain unvested.

Option transactions under the stock option plans during the three months ended March 31, 2013 were as follows:

	Number			Weighted Average Exercise Price

Exercisable as of March 31, 2013		2,666,238		$	2.20

A total of 236,356 options were exercised on a cash basis during the three months ended March 31, 2013, which resulted in proceeds to the Company of $246,989.

Cancellations for the three months ended March 31, 2013 included 357,126 options related to employee terminations.

The weighted average remaining contractual life of the outstanding options as of March 31, 2013 was 5.8 years.

The intrinsic value of outstanding and exercisable options totaled $1,660,577 and $1,641,744, respectively, as of March 31, 2013. The intrinsic value is calculated as the difference between the closing price of the Company’s common stock as of March 31, 2013, which was $2.23 per share, and the exercise price of the options.

The number of shares issuable upon the exercise of an option 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 compared to the current market price of the Company’s common stock on the date of exercise.

Note 10.    Stock Warrants

Warrants outstanding and exercisable were 450,000 at both March 31, 2013 and December 31, 2012. The weighted average exercise price for the warrants outstanding and exercisable at both March 31, 2013 and December 31, 2012 was $5.00. The weighted average remaining contractual life of the warrants outstanding as of March 31, 2013 was 3.29 years.

There was no intrinsic value associated with the outstanding and exercisable warrants as of March 31, 2013. The intrinsic value is calculated as the difference between the closing price of the Company’s common stock as of March 31, 2013, which was $2.23 per share, and the exercise price of the warrants.

The number of shares issuable upon the exercise of 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 warrant compared to the current market price of the Company’s common stock on the date of exercise.

Note 11. Employee Stock Purchase Plan

Under the Company’s 2010 Employee Stock Purchase Plan (“ESPP Plan”), participants can purchase shares of the Company’s stock at a 15% discount. A maximum of 200,000 shares of common stock can be issued under the ESPP Plan. During the three months ended March 31, 2013, a total of 10,609 shares were issued under the ESPP Plan with a fair value of $23,658. The Company recognized $3,501 and $4,390 of stock-based compensation related to the 15% discount for the three months ended March 31, 2013 and 2012, respectively.

Note 12. Fair Value Measurement

Valuation Hierarchy

The accounting standard of the Financial Accounting Standards Board (“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.

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. There were no changes in the valuation techniques during the three months ended March 31, 2013.

	Total Carrying Value		Quoted prices in active markets (Level 1)		Significant other observable inputs (Level 2)		Significant unobservable inputs (Level 3)
March 31, 2013	$	40,329,318	$	40,329,318	$	-	$	-

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. All potentially dilutive common shares have been excluded since their inclusion would be anti-dilutive.

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, 2013 would dilute earnings per share if the Company becomes profitable in the future. The exercise of the outstanding stock options and warrants could potentially generate proceeds up to approximately $13,246,000 if exercised by the holder for cash.

During the first quarter of 2013, the Company renewed a one year information technology infrastructure support agreement. The agreement became effective at the end of the first quarter of 2013. The monthly payments are approximately $43,000 and will be paid on a quarterly basis through the fourth quarter of 2013.

Note 15. Segment Information

The Company has two reportable segments: Fixed Wireless and Shared Wireless Infrastructure. Management evaluates performance and allocates resources based on the operating performance of each segment as well as the long-term growth potential for each segment. Costs reported for each segment include costs directly associated with a segment’s operations. Intersegment revenues and expenses are eliminated in consolidation.

The balance of the Company’s operations is in the Corporate group which includes centralized operations. This group includes operations related to corporate overhead and centralized activities which support our overall operations. Corporate overhead includes administrative personnel, including executive management, and other support functions such as information technology and facilities. Centralized operations includes network operations, customer care, and the management of network assets. The Corporate group is treated as a separate segment consistent with how management monitors and analyzes financial results. Corporate costs are not allocated to the segments because such costs are managed and controlled on a functional basis that encompasses all markets, with centralized, functional management held accountable for corporate results. Management also believes that not allocating these centralized costs provides a better reflection of the direct operating performance of each segment. The table below presents information about our operating segments:

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion and analysis summarizes the significant factors affecting our condensed consolidated results of operations, financial condition and liquidity position for the three months ended March 31, 2013. This discussion and analysis should be read in conjunction with our audited financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2012 and the condensed consolidated unaudited financial statements and related notes included elsewhere in this filing. The following discussion and analysis contains forward-looking statements that reflect our plans, estimates, and beliefs. Our actual results could differ materially from those discussed in the forward-looking statements.

Overview - Fixed Wireless

We provide fixed wireless broadband services to commercial customers and deliver access over a wireless network transmitting over both regulated and unregulated radio spectrum. Our service supports bandwidth on demand, wireless redundancy, virtual private networks (“VPNs”), disaster recovery, bundled data and video services. We provide service to business customers in New York City, Boston, Chicago, Los Angeles, San Francisco, Seattle, Miami, Dallas-Fort Worth, Houston, Philadelphia, Nashville, Las Vegas-Reno and Providence-Newport.

In August 2012, we entered into a binding merger agreement with Delos Internet (“Delos”) pursuant to which a wholly owned subsidiary of ours would be merged with and into Delos, with Delos becoming a wholly owned subsidiary of ours. Delos operates in Houston, Texas. We closed the acquisition of Delos in February 2013.

Characteristics of Revenues and Expenses

We offer our fixed wireless broadband services under agreements for periods ranging between one to three years. Pursuant to these agreements, we bill customers on a monthly basis, in advance, for each month of service. Payments received in advance of services performed are recorded as deferred revenues and recognized as revenue ratably over the service period.

Costs of revenues consists of expenses that are directly related to providing services to our customers, including Core Network expenses (tower and roof rent and utilities, bandwidth costs, Points of Presence (“PoP”) maintenance and other) and Customer Network expenses (customer maintenance, non-installation fees and other customer specific expenses).  We collectively refer to Core Network and Customer Network as our “Network,” and Core Network costs and Customer Network costs as “Network Costs.”  When we first enter a new market, or expand in an existing market, we are required to incur up-front costs in order to be able to provide wireless broadband services to commercial customers.  We refer to these activities as establishing a “Network Presence.” These costs include constructing PoPs in buildings in which we have a lease agreement (“Company Locations”) where we install a substantial amount of equipment in order to connect numerous customers to the Internet.  The costs to build PoPs are capitalized and expensed over a five year period.  In addition to building PoPs, we also enter into tower and roof rental agreements, secure bandwidth and incur other Network Costs.  Once we have established a Network Presence in a new market or expanded our Network Presence in an existing market, we are capable of servicing a significant number of customers through that Network Presence.  The variable cost to add new customers is relatively modest, especially compared to the up-front cost of establishing or expanding our Network Presence.  As a result, our gross margins in a market normally increase over time as we add new customers in that market.  However, we may experience variability in gross margins during periods in which we are expanding our Network Presence in a market.

13

Sales and marketing expenses primarily consist of the salaries, benefits, travel and other costs of our sales and marketing teams, as well as marketing initiatives and business development expenses.

Customer support services include salaries and related payroll costs associated with our customer support services, customer care, and installation and operations staff.

General and administrative expenses include costs attributable to corporate overhead and the overall support of our operations. Salaries and other related payroll costs for executive management, finance, administration and information systems personnel are included in this category. Other costs include office rent, utilities and other facilities costs, accounting, legal and other professional services, and other general operating expenses.

Market Information

As of March 31, 2013, we operated in thirteen metropolitan markets consisting of New York, Boston, Los Angeles, Chicago, San Francisco, Miami, Seattle, Dallas-Fort Worth, Houston, Philadelphia, Nashville, Las Vegas-Reno and Providence-Newport. The markets were launched at different times, and as a result, may have different operating metrics based on their size and stage of maturation. We incur significant up-front costs in order to establish a Network Presence in a new market.  These costs include building PoPs and incurring Network Costs.  Other material costs include hiring and training sales and marketing personnel who will be dedicated to securing customers in that market. Once we have established a Network Presence in a new market, we are capable of servicing a significant number of customers. The rate of customer additions varies from market to market, and we are unable to predict how many customers will be added in a market during any specific period. We believe that providing operating information regarding each of our markets provides useful information to shareholders in understanding the leveraging potential of our business model, the operating performance of our mature markets, and the long-term potential for our newer markets. Set forth below is a summary of our operating performance on a per-market basis, and a description of how each category is determined.

Revenues: Revenues are allocated based on which market each customer is located in.

Costs of Revenues: Includes payroll, Core Network costs and Customer Network costs that can be allocated to a specific market.

Operating Costs: Represents costs that can be specifically allocated to a market which include direct sales personnel, certain direct marketing expenses, certain customer support and installation payroll expenses and third party commissions.

Corporate: Includes corporate overhead and centralized activities which support our overall operations. Corporate overhead includes administrative personnel, including executive management, and other support functions such as information technology and facilities. Centralized operations include network operations, customer care, and the management of network assets.

Shared Wireless Infrastructure, net: Represents the net operating results for that business segment.

Non-Core Expenses: These costs related to our efforts in 2012 to develop other wireless technology solutions and services, and primarily consisted of rent payments for street level rooftops, costs associated with constructing an offload network and payroll costs for employees working on these projects.

Adjusted Market EBITDA: Represents a market’s income (loss) before interest, taxes, depreciation, amortization, stock-based compensation, and other income (expense). We believe this metric provides useful information regarding the operating cash flow being generated in a market.

We entered the Houston market in February 2013 through the acquisition of Delos.

Supplemental Segment Information

Operating information about each segment in accordance with generally accepted principles is disclosed in Note 15 of the financial statements. In addition, we use other non-GAAP measurements to assess the operating performance of each segment. These non-GAAP financial measures are commonly used by investors, financial analysts, and rating agencies. Management believes that these non-GAAP financial measures should be available so that investors have the same data that management employs in assessing our overall operations.

EBITDA, a non-GAAP financial measure, is calculated as net income (loss) before interest, income taxes, depreciation and amortization. We define adjusted EBITDA as net income (loss) before interest, income taxes, depreciation and amortization expenses, excluding when applicable, stock-based compensation, other non-operating income or expenses as well as gain or loss on (i) disposal of property and equipment, (ii) nonmonetary transactions, and (iii) business acquisitions.

Net Cash Flow is another commonly used non- GAAP financial measure. Net Cash Flow is defined as Adjusted EBITDA less capital expenditures.

Three Months Ended March 31, 2013 Compared to Three Months Ended March 31, 2012

Revenues. Revenues totaled $8,299,223 during the three months ended March 31, 2013 compared to $7,819,059 during the three months ended March 31, 2012 representing an increase of $480,164, or 6%. This increase was primarily related to higher monthly recurring revenue (“MRR”) of approximately $200,000, or 3%, in the quarter ended March 31, 2013 compared to the quarter ended March 31, 2012, of which approximately $146,000 related to organic growth and approximately $54,000 related to a month of revenue from the Delos acquisition. In addition, revenue generated from temporary connections increased by approximately $168,000, or 128%, in the quarter ended March 31, 2013 compared to the quarter ended March 31, 2012.

Average revenue per user (“ARPU”) as of March 31, 2013 totaled $727 compared to $706 as of March 31, 2012 representing an increase of $21, or 3%. ARPU for new customers for the quarter ended March 31, 2013 totaled $630 compared to $545 for the quarter ended March 31, 2012, representing an increase of $85, or 16%. The increase in ARPU primarily related to a higher percentage of customers purchasing, or upgrading to, higher bandwidth service which generates greater MRR. In addition, the customers acquired from Delos in February 2013 had an ARPU of $864 compared to $721 for our existing customer base which had the effect of increasing our post-acquisition ARPU by $3.

Customer churn, calculated as a percent of revenue lost on a monthly basis from customers terminating service or reducing their service level, totaled 1.64% for the three months ended March 31, 2013 compared to 1.58% for the three months ended March 31, 2012. Our goal is to maintain churn levels between 1.4% and 1.7% which we believe is below industry averages of approximately 2.0%.

Cost of Revenues.    Cost of revenues totaled $5,230,641 for the three months ended March 31, 2013 compared to $3,072,767 for the three months ended March 31, 2012 representing an increase of $2,157,874, or 70%. On a consolidated basis, gross margin for the three months ended March 31, 2013 was 37% as compared to 61% for the three months ended March 31, 2012 representing a decrease of 24 percentage points.  Higher rent expense associated with both PoPs for the fixed wireless network and street level rooftops for the shared wireless infrastructure network increased cost of revenues by 106% in dollars and reduced gross margin by 28 percentage points.  These increases were partially offset by lower Customer Network and other costs which decreased by 6% in dollars and which benefited gross margin by 2 percentage points.

Depreciation and Amortization.    Depreciation and amortization totaled $3,871,087for the three months ended March 31, 2013 compared to $3,281,079 for the three months ended March 31, 2012, representing an increase of $590,008, or 18%. Depreciation expense totaled $3,118,487 for the three months ended March 31, 2013 compared to $2,227,928 for the three months ended March 31, 2012 representing an increase of $890,559, or 40%. The gross base of depreciable assets as of March 31, 2013 increased by $20,444,741, or 36%, compared to March 31, 2012. The increase in the depreciable base during the twelve months ended March 31, 2013 reflects continued growth in our fixed wireless network (approximately $10,455,000), spending on our shared wireless infrastructure (approximately $8,495,000) and additions resulting from acquisitions (approximately $827,000).

Amortization expense totaled $752,600 for the three months ended March 31, 2013 compared to $1,053,151 for the three months ended March 31, 2012 representing a decrease of $300,551, or 29%. Amortization expense relates to customer related intangible assets recorded in connection with acquisitions and can fluctuate significantly from period to period depending upon the timing of acquisitions, the relative amounts of intangible assets recorded, and the amortization periods. The decrease was primarily related to the acquisition of Pipeline Wireless LLP (“Pipeline”), which was fully depreciated in May 2012, partially offset by one month’s amortization recorded in connection with the Delos acquisition.

Customer Support Services.    Customer support services totaled $1,147,559 for the three months ended March 31, 2013 compared to $1,161,965 for the three months ended March 31, 2012 representing a decrease of $14,406, or 1%. Average headcount increased from 76 during the 2012 period to 77 during the 2013 period.

Sales and Marketing. Sales and marketing expenses for the three months ended March 31, 2013 totaled $1,440,856 compared to $1,481,989 for the three months ended March 31, 2012 representing a decrease of $41,133, or 3%. This decrease was primarily related to a decrease in commissions and bonuses of approximately $40,000.

General and Administrative.    General and administrative expenses totaled $3,137,599 for the three months ended March 31, 2013 compared to $3,191,323 for the three months ended March 31, 2012 representing a decrease of $53,724, or 2%. On a functional basis, increases in professional services (approximately $159,000), information technology (approximately $58,000), and payroll (approximately $50,000) were offset by decreases in acquisition costs (approximately $288,000) and stock-based compensation (approximately $128,000).

16

Interest Income. Interest income for the three months ended March 31, 2013 totaled $154 compared to $17,178 for the three months ended March 31, 2012 representing a decrease of $17,024, or 99%. The decrease relates to less interest earned on our cash accounts during the 2013 period.

Interest Expense.    Interest expense for the three months ended March 31, 2013 totaled $35,768 compared to $22,316 for the three months ended March 31, 2012 representing an increase of $13,452, or 60%. The increase in interest expense was primarily related to additional capital leases acquired.

Gain on Business Acquisition.  Gain on business acquisition totaled $941,457 for the three months ended March 31, 2013 compared to zero for the three months ended March 31, 2012.  The gain in the 2013 period related to the acquisition of Delos in February 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, we were able to acquire the customer relationships and wireless network of Delos at a discounted price.

Net Loss.    Net loss for the three months ended March 31, 2013 totaled $5,626,306 compared to $4,380,132 for the three months ended March 31, 2012 representing an increase of $1,246,174, or 28%. Revenues increased by $480,164, or 6%, while operating expenses increased by $2,638,619, or 22%. In addition, non-operating income totaled $902,213 for the three months ended March 31, 2013 compared with non-operating expense of $10,068 for the three months ended March 31, 2012.

Liquidity and Capital Resources

We have historically met our liquidity and capital requirements primarily through the public sale and private placement of equity securities and debt financing. Changes in capital resources during the three months ended March 31, 2013 and 2012 are described below.

Net Cash Used in Operating Activities.    Net cash used in operating activities for the three months ended March 31, 2013 totaled $4,422,727 compared to $2,373,948 for the three months ended March 31, 2012 representing an increase of $2,048,779, or 86%. Cash used in operations for the three months ended March 31, 2013 totaled $2,287,184 as compared to $553,717 for the three months ended March, 31, 2012. Changes in operating assets and liabilities generally represent timing differences regarding payments and receipts, and are normally not indicative of operating results.  During the three months ended March 31, 2013, changes in operating assets and liabilities used cash of $2,135,543 compared to $1,820,231 for the three months ended March 31, 2012.

Net Cash Used in Investing Activities.    Net cash used in investing activities for the three months ended March 31, 2013 totaled $975,853 compared to $3,559,958 for the three months ended March 31, 2012 representing a decrease of $2,584,105, or 73%. The decrease in the 2013 period related to lower spending on property and equipment which decreased by $2,737,187, or 80%, from $3,434,000 to $696,813. During the 2012 period, we spent significantly on the construction of a carrier class network to offload data traffic. In addition, capital spending on the fixed wireless network was significantly lower in 2013.

Net Cash Provided by (Used In) Financing Activities.  Net cash provided by financing activities for the three months ended March 31, 2013 totaled $30,575,672 compared to net cash used in financing activities of $63,283 for the three months ended March 31, 2012, representing a decrease of $30,638,955, or greater than 100%. The increase was primarily related to net proceeds of $30,500,836 received in the first quarter of 2013 from the sale of 11,000,000 shares of our common stock at a public offering of $3.00 per share.

Acquisition of Delos. In February 2013, we completed the acquisition of Delos which was based in the Houston, Texas area. The aggregate consideration for the acquisition included (i) approximately $225,000 in cash, (ii) 433,673 shares of common stock with a fair value of approximately $1.1 million based on the market price of our common stock on the closing date, and (iii) approximately $0.1 million in assumed liabilities. The acquisition of Delos was a business combination accounted for under the acquisition method.

Underwritten Offerings. In the first quarter of 2013, we completed an underwritten offering of 11,000,000 shares of our common stock at a public offering price of $3.00 per share. The total gross proceeds of the offering were $33,000,000. Net proceeds were approximately $30,501,000, after underwriting discounts, commissions and offering expenses.

Working Capital.    As of March 31, 2013, we had working capital of $36,838,030. Based on our current operating activities and plans, we believe our existing working capital will enable us to meet our anticipated cash requirements for at least the next twelve months.

Contractual Obligations and Commitments

17

Capital Lease Obligations. We have entered into capital leases to acquire property and equipment expiring through December 2017. In December 2011, we entered into an agreement with Cisco Capital to acquire equipment related to our information technology infrastructure. The total lease obligation is approximately $2,100,000, of which the first lease for approximately $1,400,000 commenced in the second quarter of 2012. The second lease obligation of approximately $700,000 commenced at the beginning of April 2013. These leases will be paid in various installments over a 60 month period from their respective commencement dates.

Operating Leases. We have entered into operating leases related to roof rights, cellular towers, office space, and equipment leases under various non-cancelable agreements expiring through January 2023.

Deferred Payments. We are making deferred payments to Pipeline as part of the consideration paid for the acquisition. There were 14 monthly payments of approximately $16,630 remaining as of March 31, 2013.

Other. During the first quarter of 2013, we renewed a one year information technology infrastructure support agreement. The agreement became effective at the end of the first quarter of 2013. The monthly payments are approximately $43,000 and will be paid on a quarterly basis through the fourth quarter of 2013.

Critical Accounting Policies

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the amounts of revenues and expenses. Critical accounting policies are those that require the application of management’s most difficult, subjective or complex judgments, often because of the need to make estimates about the effect of matters that are inherently uncertain and that may change in subsequent periods. In preparing the financial statements, we utilize available information, including our past history, industry standards and the current economic environment, among other factors, in forming our estimates and judgments, giving appropriate consideration to materiality. Actual results may differ from these estimates. In addition, other companies may utilize different estimates which may impact the comparability of our results of operations to other companies in our industry. We believe that of our significant accounting policies, the following may involve a higher degree of judgment and estimation, or are fundamentally important to our business.

Revenue Recognition.    We normally enter into contractual agreements with our customers for periods ranging between one to three years. We recognize the total revenue provided under a contract ratably over the contract period including any periods under which we have agreed to provide services at no cost. Deferred revenues are recognized as a liability when billings are issued in advance of the date when revenues are earned. We recognize revenue when (i) persuasive evidence of an arrangement exists, (ii) delivery or installation has been completed, (iii) the customer accepts and verifies receipt, and (iv) collectability is reasonably assured.

Long-Lived Assets. Long-lived assets with definite lives consist primarily of property and equipment, and intangible assets such as acquired customer relationships. Long-lived assets are evaluated periodically for impairment or whenever events or circumstances indicate their carrying value may not be recoverable. Conditions that would result in an impairment charge include a significant decline in the fair value of an asset, a significant change in the extent or manner in which an asset is used, or a significant adverse change that would indicate that the carrying amount of an asset or group of assets is not recoverable. When such events or circumstances arise, an estimate of the future undiscounted cash flows produced by the asset, or the appropriate grouping of assets, is compared to the asset’s carrying value to determine if impairment exists. If the asset is determined to be impaired, the impairment loss is measured based on the excess of its carrying value over its fair value. Assets to be disposed of are reported at the lower of their carrying value or net realizable value.

Business Acquisitions. Business combinations are accounted for using the acquisition method. The cost of an acquisition is measured as the fair value of the consideration transferred on the acquisition date.  When we acquire a business, we assess the acquired assets and liabilities assumed for the appropriate classification and designation in accordance with the contractual terms, economic circumstances and pertinent conditions at the acquisition date. The excess of the total consideration transferred over the net identifiable assets acquired and liabilities assumed is recognized as goodwill.  If the total consideration is lower than the fair value of the identifiable net assets acquired, the difference is recognized as a gain on business acquisition. Acquisition costs are expensed and included in general and administrative expenses in our condensed consolidated statements of operations.

18

Goodwill. Goodwill represents the excess of the purchase price over the estimated fair value of identifiable net assets acquired in an acquisition. Goodwill is not amortized but rather is reviewed annually for impairment, or whenever events or circumstances indicate that the carrying value may not be recoverable. We initially perform a qualitative assessment of goodwill which considers macro-economic conditions, industry and market trends, and the current and projected financial performance of the reporting unit.  No further analysis is required if it is determined that there is a less than 50 percent likelihood that the carrying value is greater than the fair value. 

Asset Retirement Obligations. The Financial Accounting Standards Board (“FASB”) 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.  Our network equipment is installed on both buildings in which we have a lease agreement (“Company Locations”) and at customer locations.  In both instances, the installation and removal of our equipment is not complicated and does not require structural changes to the building where the equipment is installed.  Costs associated with the removal of our equipment at Company or customer locations are not material, and accordingly, we have determined that we do not presently have asset retirement obligations under the FASB’s accounting guidance.

Off-Balance Sheet Arrangements.    We have no off-balance sheet arrangements, financings, or other relationships with unconsolidated entities known as ‘‘Special Purposes Entities.’’

19

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Market risk is the potential loss arising from adverse changes in market rates and prices.  Our primary market risk relates to interest rates.  At March 31, 2013, all cash and cash equivalents are immediately available cash balances.  A portion of our cash and cash equivalents are held in three institutional money market funds.   Our interest rate risk exposure is to a decline in interest rates which would result in a decline in interest income. Due to our current market yields, a further decline in interest rates would not have a material impact on earnings.

Item 4. Controls and Procedures.

Disclosure Controls and Procedures

We carried out an evaluation, under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the ‘‘Exchange Act’’). Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Exchange Act is accumulated and communicated to the issuer’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Based upon our evaluation, our chief executive officer and chief financial officer concluded that our disclosure controls and procedures are effective, as of March 31, 2013, in ensuring that material information that we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission rules and forms.

Changes in Internal Control over Financial Reporting

There were no changes in our system of internal control over financial reporting during the three months ended March 31, 2013 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Business Combination Disclosure [Text Block]

Note 3.    Business Acquisitions

Delos Internet

In February 2013, the Company completed the acquisition of Delos Internet (“Delos”). The Company obtained full control of Delos in the acquisition. The Company has determined that the acquisition of Delos 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:

Fair value of consideration transferred:
Cash	$	225,000
Common stock (433,673 shares)		1,071,172
Capital lease obligations assumed		128,929
		1,425,101
Recognized amounts of identifiable assets acquired and liabilities assumed:

Cash		2,058
Accounts receivable		80,524
Property and equipment		826,524
Security deposits		1,993
Accounts payable		(26,970	)
Deferred revenue		(62,110	)
Other liabilities		(89,930	)
Total identifiable net tangible assets		732,089
Customer relationships		1,634,469
Total identifiable net assets		2,366,558
Gain on business acquisition	$	941,457

The Company recognized a gain on business acquisition of $941,457 which is included in other income (expense) in the Company’s condensed consolidated statements of operations for the three months ended March 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.

The results of operations of Delos have been included in the Company’s condensed consolidated statements of operations since the completion of the acquisition in February 2013. Revenues generated from customers acquired from Delos totaled approximately $56,000 for the three months ended March 31, 2013.

During the three months ended March 31, 2013, the Company incurred approximately $58,000 of third-party costs in connection with the Delos acquisition. These expenses are included in the general and administrative expenses in the Company’s condensed consolidated statements of operations for the three months ended March 31, 2013.

Pro Forma Information

The following table reflects the unaudited pro forma consolidated results of operations had the acquisition taken place at the beginning of the 2013 and 2012 periods:

	Three Months Ended March 31,
	2013			2012
Revenues	$	8,411,793		$	7,987,914

Summary of Significant Accounting Policies

Accounting Policies [Abstract]

Significant Accounting Policies [Text Block]

Note 2.    Summary of Significant Accounting Policies

Basis of Presentation. The condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial statements and with Form 10-Q and Article 10 of Regulation S-X of the United States Securities and Exchange Commission (“SEC”). Accordingly, they do not contain all information and footnotes required by accounting principles generally accepted in the United States of America for annual financial statements. The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. In the opinion of the Company’s management, the accompanying unaudited condensed consolidated financial statements contain all the adjustments necessary (consisting only of normal recurring accruals) to present the financial position of the Company as of March 31, 2013 and the results of operations and cash flows for the periods presented. The results of operations for the three months ended March 31, 2013 are not necessarily indicative of the operating results for the full fiscal year for any future period.

These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. 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, 2012, and updated, as necessary, in this Quarterly Report on Form 10-Q.

Use of Estimates.    The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the amounts of revenues and expenses. Actual results could differ from those estimates.

Cash and Cash Equivalents.    The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents.

Concentration of Credit Risk.    Financial instruments that potentially subject the Company to significant concentrations of credit risk consist of cash and cash equivalents. At times, our cash and cash equivalents may be uninsured or in deposit accounts that exceed the Federal Deposit Insurance Corporation (“FDIC”) insurance limits. As of March 31, 2013, the Company had cash and cash equivalent balances of approximately $32,313,000 in excess of the federally insured limit of $250,000.

The Company also had approximately $7,766,000 invested in three institutional money market funds. These funds are protected under the Securities Investor Protection Corporation, a nonprofit membership corporation which provides limited coverage up to $500,000.

Accounts Receivable. Accounts receivable are stated at cost less an allowance for doubtful accounts which reflects the Company’s estimate of balances that will be not collected. The allowance is based on the history of past write-offs, the aging of balances, collections experience and current credit conditions. Additions include provisions for doubtful accounts and deductions include customer write-offs. Changes in the allowance for doubtful accounts were as follows:

Business Acquisitions. Business combinations are accounted for using the acquisition method. The cost of an acquisition is measured as the fair value of the consideration transferred on the acquisition date.  When the Company acquires a business, it assesses the acquired assets and liabilities assumed for the appropriate classification and designation in accordance with the contractual terms, economic circumstances and pertinent conditions at the acquisition date. The excess of the total consideration transferred over the net identifiable assets acquired and liabilities assumed is recognized as goodwill.  If this consideration is lower than the fair value of the identifiable net assets acquired, the difference is recognized as a gain on business acquisition. Acquisition costs are expensed and included in general and administrative expenses in our condensed consolidated statements of operations.

Revenue Recognition. The Company normally enters into contractual agreements with its customers for periods ranging between one to three years. The Company recognizes the total revenue provided under a contract ratably over the contract period, including any periods under which the Company has agreed to provide services at no cost. The Company recognizes revenue when (i) persuasive evidence of an arrangement exists, (ii) delivery or installation has been completed, (iii) the customer accepts and verifies receipt, and (iv) collectability is reasonably assured.

Deferred Revenues. Customers are billed monthly in advance. Deferred revenues are recognized for that portion of monthly charges not yet earned as of the end of the reporting period. Deferred revenues are also recognized for certain customers who pay for their services in advance.

Goodwill. Goodwill represents the excess of the purchase price over the estimated fair value of identifiable net assets acquired in an acquisition. Goodwill is not amortized but rather is reviewed annually for impairment, or whenever events or circumstances indicate that the carrying value may not be recoverable. The Company initially performs a qualitative assessment of goodwill which considers macro-economic conditions, industry and market trends, and the current and projected financial performance of the reporting unit.  No further analysis is required if it is determined that there is a less than 50 percent likelihood that the carrying value is greater than the fair value. 

Reclassifications.    Certain accounts in the prior years’ consolidated financial statements have been reclassified for comparative purposes to conform to the presentation in the current year consolidated financial statements. These reclassifications have no effect on the previously reported net loss.

Subsequent Events. Subsequent events have been evaluated through the date of this filing.

Mar. 31, 2013

Accounting Policies [Abstract]

Basis Of Accountings, Policy [Policy Text Block]

Basis of Presentation. The condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial statements and with Form 10-Q and Article 10 of Regulation S-X of the United States Securities and Exchange Commission (“SEC”). Accordingly, they do not contain all information and footnotes required by accounting principles generally accepted in the United States of America for annual financial statements. The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. In the opinion of the Company’s management, the accompanying unaudited condensed consolidated financial statements contain all the adjustments necessary (consisting only of normal recurring accruals) to present the financial position of the Company as of March 31, 2013 and the results of operations and cash flows for the periods presented. The results of operations for the three months ended March 31, 2013 are not necessarily indicative of the operating results for the full fiscal year for any future period.

These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. 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, 2012, and updated, as necessary, in this Quarterly Report on Form 10-Q.

Use of Estimates, Policy [Policy Text Block]

Use of Estimates.    The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the amounts of revenues and expenses. Actual results could differ from those estimates.

Cash and Cash Equivalents, Policy [Policy Text Block]

Cash and Cash Equivalents.    The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents.

Concentrations Of Credit Risk, Policy [Policy Text Block]

Concentration of Credit Risk.    Financial instruments that potentially subject the Company to significant concentrations of credit risk consist of cash and cash equivalents. At times, our cash and cash equivalents may be uninsured or in deposit accounts that exceed the Federal Deposit Insurance Corporation (“FDIC”) insurance limits. As of March 31, 2013, the Company had cash and cash equivalent balances of approximately $32,313,000 in excess of the federally insured limit of $250,000.

The Company also had approximately $7,766,000 invested in three institutional money market funds. These funds are protected under the Securities Investor Protection Corporation, a nonprofit membership corporation which provides limited coverage up to $500,000.

Receivables, Policy [Policy Text Block]

Accounts Receivable. Accounts receivable are stated at cost less an allowance for doubtful accounts which reflects the Company’s estimate of balances that will be not collected. The allowance is based on the history of past write-offs, the aging of balances, collections experience and current credit conditions. Additions include provisions for doubtful accounts and deductions include customer write-offs. Changes in the allowance for doubtful accounts were as follows:

	Three Months Ended March 31,
	2013			2012
Beginning of period	$	190,109		$	262,525
Additions		-			30,000
Deductions		(46,672	)		(49,537	)
End of period	$	143,437		$	242,988

Business Combinations Policy [Policy Text Block]

Business Acquisitions. Business combinations are accounted for using the acquisition method. The cost of an acquisition is measured as the fair value of the consideration transferred on the acquisition date.  When the Company acquires a business, it assesses the acquired assets and liabilities assumed for the appropriate classification and designation in accordance with the contractual terms, economic circumstances and pertinent conditions at the acquisition date. The excess of the total consideration transferred over the net identifiable assets acquired and liabilities assumed is recognized as goodwill.  If this consideration is lower than the fair value of the identifiable net assets acquired, the difference is recognized as a gain on business acquisition. Acquisition costs are expensed and included in general and administrative expenses in our condensed consolidated statements of operations.

Revenue Recognition, Policy [Policy Text Block]

Revenue Recognition. The Company normally enters into contractual agreements with its customers for periods ranging between one to three years. The Company recognizes the total revenue provided under a contract ratably over the contract period, including any periods under which the Company has agreed to provide services at no cost. The Company recognizes revenue when (i) persuasive evidence of an arrangement exists, (ii) delivery or installation has been completed, (iii) the customer accepts and verifies receipt, and (iv) collectability is reasonably assured.

Revenue Recognition, Deferred Revenue [Policy Text Block]

Deferred Revenues. Customers are billed monthly in advance. Deferred revenues are recognized for that portion of monthly charges not yet earned as of the end of the reporting period. Deferred revenues are also recognized for certain customers who pay for their services in advance.

Goodwill and Intangible Assets, Policy [Policy Text Block]

Goodwill. Goodwill represents the excess of the purchase price over the estimated fair value of identifiable net assets acquired in an acquisition. Goodwill is not amortized but rather is reviewed annually for impairment, or whenever events or circumstances indicate that the carrying value may not be recoverable. The Company initially performs a qualitative assessment of goodwill which considers macro-economic conditions, industry and market trends, and the current and projected financial performance of the reporting unit.  No further analysis is required if it is determined that there is a less than 50 percent likelihood that the carrying value is greater than the fair value. 

Reclassification, Policy [Policy Text Block]

Reclassifications.    Certain accounts in the prior years’ consolidated financial statements have been reclassified for comparative purposes to conform to the presentation in the current year consolidated financial statements. These reclassifications have no effect on the previously reported net loss.

Subsequent Events, Policy [Policy Text Block]

Subsequent Events. Subsequent events have been evaluated through the date of this filing.

Organization and Nature of Business

Organization, Consolidation and Presentation Of Financial Statements [Abstract]

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 (“VPNs”), disaster recovery, bundled data and video services. The Company provides services to approximately 3,600 business customers in New York City, Boston, Chicago, Los Angeles, San Francisco, Seattle, Miami, Dallas-Fort Worth, Houston, Philadelphia, Nashville, Las Vegas-Reno and Providence-Newport. The Company's “fixed wireless business” has grown both organically and through the acquisition of five other fixed wireless broadband providers in various markets.

Since 2010, the Company has been exploring opportunities to leverage its fixed wireless network in urban markets to provide other wireless technology solutions and services. Over the past few years, a significant increase in mobile data generated by smartphones, tablets and other devices has placed tremendous demand on the networks of the carriers. This has caused the carriers to explore a wide range of solutions including (i) acquiring additional spectrum, (ii) employing Wi-Fi to offload data traffic and (iii) utilizing small cell technologies to increase capacity in dense urban areas. During this period, the Company has incurred various costs related to identifying possible new solutions and services. These costs included (a) rent payments under lease agreements which provide the right to install wireless technology equipment on street level rooftops, and (b) construction of a carrier-class network to offload data traffic. The Company has entered into the lease agreements and commenced these capital projects for the purpose of securing capacity that it believes is needed to maintain its competitive position in the wireless industry. The Company believes that the wireless communications industry is experiencing a fundamental shift from its current, macro-cellular architecture to hyper-densified Small Cell architecture where existing cell sites will be supplemented by many smaller base stations operating near street level. The Company also believes that Wi-Fi will be an integral component of Small Cell architecture.

In January 2013, the Company incorporated a wholly-owned subsidiary, Hetnets Tower Corporation (“Hetnets”). The Company plans to transfer certain assets to Hetnets to support the operation of a shared wireless infrastructure business. Hetnets plans to generate rental income from four separate sources including (i) rental of space on street level rooftops for the installation of customer owned Small Cells which includes Wi-Fi antennae, DAS, and Metro and Pico cells, (ii) rental of a channel on Hetnets’ Wi-Fi network for the offloading of mobile data, (iii) rental of cabinets, switch ports, interconnection services, including backhaul or transport, and (iv) rental of power and power backup. The Company refers to the activities of Hetnets as its "shared wireless infrastructure business."

Note 12. Fair Value Measurement

Valuation Hierarchy

The accounting standard of the Financial Accounting Standards Board (“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.

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. There were no changes in the valuation techniques during the three months ended March 31, 2013.

Earnings Per Share [Abstract]

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. All potentially dilutive common shares have been excluded since their inclusion would be anti-dilutive.

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, 2013 would dilute earnings per share if the Company becomes profitable in the future. The exercise of the outstanding stock options and warrants could potentially generate proceeds up to approximately $13,246,000 if exercised by the holder for cash.

Stock Options and Restricted Stock Awards [Text Block]

Note 9. Stock-Based Compensation

The Company uses the Black-Scholes option pricing 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. Stock-based compensation totaled $378,205 and $490,325 for the three months ended March 31, 2013 and 2012, respectively. 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 $1,322,797 as of March 31, 2013 which will be recognized over a weighted-average period of 2.0 years.

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:

	Three Months Ended March 31,
	2013			2012
Risk-free interest rate		0.8	%		0.7%-1.0 %
Expected volatility		68	%		65% - 73%
Expected life (in years)		5			5
Expected dividend yield		-			–
Weighted average per share grant date fair value	$	1.46		$	2.18

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. 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.

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 vests over a three year period, of which 45,000 shares were vested as of March 31, 2013. Stock-based compensation for restricted stock totaled $14,775 and $29,550 for the three months ended March 31, 2013 and 2012, respectively. Unrecognized compensation cost of $44,325 at March 31, 2013 will be recognized ratably through December 2013. As of March 31, 2013, 15,000 shares of restricted stock remain unvested.

Option transactions under the stock option plans during the three months ended March 31, 2013 were as follows:

	Number			Weighted Average Exercise Price
Outstanding as of December 31, 2012		3,916,045		$	2.85
Granted during 2013		75,000			2.62
Exercised		(236,356	)		1.04
Forfeited /expired		(357,126	)		5.18
Outstanding as of March 31, 2013		3,397,563		$	2.73
Exercisable as of March 31, 2013		2,666,238		$	2.20

A total of 236,356 options were exercised on a cash basis during the three months ended March 31, 2013, which resulted in proceeds to the Company of $246,989.

Cancellations for the three months ended March 31, 2013 included 357,126 options related to employee terminations.

The weighted average remaining contractual life of the outstanding options as of March 31, 2013 was 5.8 years.

The intrinsic value of outstanding and exercisable options totaled $1,660,577 and $1,641,744, respectively, as of March 31, 2013. The intrinsic value is calculated as the difference between the closing price of the Company’s common stock as of March 31, 2013, which was $2.23 per share, and the exercise price of the options.

The number of shares issuable upon the exercise of an option 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 compared to the current market price of the Company’s common stock on the date of exercise.

Warrants outstanding and exercisable were 450,000 at both March 31, 2013 and December 31, 2012. The weighted average exercise price for the warrants outstanding and exercisable at both March 31, 2013 and December 31, 2012 was $5.00. The weighted average remaining contractual life of the warrants outstanding as of March 31, 2013 was 3.29 years.

There was no intrinsic value associated with the outstanding and exercisable warrants as of March 31, 2013. The intrinsic value is calculated as the difference between the closing price of the Company’s common stock as of March 31, 2013, which was $2.23 per share, and the exercise price of the warrants.

The number of shares issuable upon the exercise of 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 warrant compared to the current market price of the Company’s common stock on the date of exercise.

Segment Reporting [Abstract]

Segment Reporting Disclosure [Text Block]

Note 15. Segment Information

The Company has two reportable segments: Fixed Wireless and Shared Wireless Infrastructure. Management evaluates performance and allocates resources based on the operating performance of each segment as well as the long-term growth potential for each segment. Costs reported for each segment include costs directly associated with a segment’s operations. Intersegment revenues and expenses are eliminated in consolidation.

The balance of the Company’s operations is in the Corporate group which includes centralized operations. This group includes operations related to corporate overhead and centralized activities which support our overall operations. Corporate overhead includes administrative personnel, including executive management, and other support functions such as information technology and facilities. Centralized operations includes network operations, customer care, and the management of network assets. The Corporate group is treated as a separate segment consistent with how management monitors and analyzes financial results. Corporate costs are not allocated to the segments because such costs are managed and controlled on a functional basis that encompasses all markets, with centralized, functional management held accountable for corporate results. Management also believes that not allocating these centralized costs provides a better reflection of the direct operating performance of each segment. The table below presents information about our operating segments:
