Significant Accounting Policies [Text Block]	Note 3 - Basis of Presentation and Summary of Significant Accounting Policies Basis of Presentation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Retroactive Adjustment For Reverse Stock Split s On July 7, 2016, one twenty stock split of its common stock. On September 29, 2017, one seventy-five Consequently, all earnings per share and other share related amounts and disclosures have been retroactively adjusted for all periods presented for the reverse stock splits. 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. Key estimates include fair value of certain financial instruments, carrying value of intangible assets, reserves for accounts receivable and accruals for liabilities. Cash and Cash Equivalents The Company considers all highly liquid investments with a maturity of three 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, the Company ’s cash and cash equivalents may December 31, 2017, $7.3 $250,000. Accounts Receivable, Net Accounts receivable are stated at cost less an allowance for doubtful accounts which reflects the Company ’s estimate of balances that will not Property and Equipment and depreciation Property and equipment are stated at cost and include equipment, installation costs and materials. Depreciation is calculated on a straight-line basis over the estimated useful lives of the assets.

Network, base station and customer premise equipment are depreciated over estimated useful lives of five three five three five not FCC Licenses Federal Communications Commission (“FCC”) licenses are initially recorded at cost and are considered to be intangible assets with an indefinite life because the Company is able to maintain the license indefinitely as long as it complies with certain FCC requirements. The Company intends to and has demonstrated an ability to maintain compliance with such requirements. The Financial Accounting Standards Board ’s (“FASB”) guidance on goodwill and other intangible assets states that an asset with an indefinite useful life is not Long-Lived Assets Long-lived assets with definitive lives consist primarily of property and equipment, and certain intangible assets. Long-lived assets are evaluated periodically for impairment, or whenever events or circumstances indicate their carrying value may not not ’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. The FASB ’s guidance on asset retirement obligations addresses financial accounting and reporting for obligations associated with the retirement of tangible long-lived assets and the associated costs. This guidance requires the recognition of an asset retirement obligation and an associated asset retirement cost when there is a legal obligation associated with the retirement of tangible long-lived assets. The Company’s network equipment is installed on both buildings in which the Company has a lease agreement and at customer locations. In both instances, the installation and removal of the Company’s equipment is not not not not 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 may not No 50 no December 31, 201 7 2016, Fair Value of Financial Instruments The Company has categorized its financial assets and liabilities measured at fair value into a three ’s guidance. Fair value is defined as an exit price, the amount that would be received upon the sale of an asset or paid upon the transfer of a liability in an orderly transaction between market participants at the measurement date. The degree of judgment utilized in measuring the fair value of assets and liabilities generally correlates to the level of pricing observability. Financial assets and liabilities with readily available, actively quoted prices or for which fair value can be measured from actively quoted prices in active markets generally have more pricing observability and require less judgment in measuring fair value. Conversely, financial assets and liabilities that are rarely traded or not Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in operations in the period enacted. A valuation allowance is provided when it is more likely than not not ’s income tax returns are recognized in the consolidated financial statements if such positions are more likely than not On December 22, 2017, 21 January 1, 2018. 740, ’s federal deferred tax asset and liability balances, which are computed utilizing the new rates in the period for which the tax law was enacted with a corresponding net adjustment to deferred income tax expense (or benefit) and the effect to the valuation allowance. The change in the federal rate as a result of the Act is reflected as a discreet item within the rate reconciliation and the effect of the remeasurement of the deferred taxes is also included in the deferred tax and valuation allowance disclosure. Revenue Recognition The Company normally enters into contractual agreements with its customers for periods ranging between one three no 104, 104” Deferred Revenues Customers are billed monthly in advance. Deferred revenues are recognized for that portion of monthly charges not Deferred Rent The Company records rent expense on operating leases on a straight-line basis over the minimum lease term.

Advertising costs for the years ended December 31, 201 7 2016 $84,000 $245,000, Stock-Based Compensation The Company accounts for stock-based awards issued to employees in accordance with FASB guidance. Such awards primarily consist of options to purchase shares of common stock. The fair value of stock-based awards is determined on the grant date using a valuation model. The fair value is recognized as compensation expense, net of estimated forfeitures, on a straight -line basis over the service period which is normally the vesting period. Basic and Diluted Net Loss Per Share Basic and diluted net loss per share has been calculated by dividing net loss by the weighted average number of shares of common stock outstanding during the period. The following common stock equivalents were excluded from the computation of diluted net loss per share of common stock because they were anti-dilutive. The exercise of these common stock equivalents would dilute earnings per shares if the Company becomes profitable in the future.

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.

Goodwill and Intangible Assets, Intangible Assets, Indefinite-Lived, Policy [Policy Text Block]	FCC Licenses Federal Communications Commission (“FCC”) licenses are initially recorded at cost and are considered to be intangible assets with an indefinite life because the Company is able to maintain the license indefinitely as long as it complies with certain FCC requirements.

Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]	Long-Lived Assets Long-lived assets with definitive lives consist primarily of property and equipment, and certain intangible assets.

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. The FASB ’s guidance on asset retirement obligations addresses financial accounting and reporting for obligations associated with the retirement of tangible long-lived assets and the associated costs. This guidance requires the recognition of an asset retirement obligation and an associated asset retirement cost when there is a legal obligation associated with the retirement of tangible long-lived assets.

Fair value is defined as an exit price, the amount that would be received upon the sale of an asset or paid upon the transfer of a liability in an orderly transaction between market participants at the measurement date. The degree of judgment utilized in measuring the fair value of assets and liabilities generally correlates to the level of pricing observability. Financial assets and liabilities with readily available, actively quoted prices or for which fair value can be measured from actively quoted prices in active markets generally have more pricing observability and require less judgment in measuring fair value. Conversely, financial assets and liabilities that are rarely traded or not
