Management determines the allowance for doubtful accounts by regularly evaluating individual customer receivables and considering a customer’s financial condition, credit history and current economic conditions. Trade receivables are written off against the allowance when deemed uncollectible. Recoveries of trade receivables previously written off are recorded when received.

Inventory is stated at the lower of cost or net realizable value. Cost is determined using the weighted-average method. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. For the Telco segment, the Company records an inventory reserve provision to reflect inventory at its estimated net realizable value based on a review of inventory quantities on hand, historical sales volumes and technology changes. These reserves are to provide for items that are potentially slow-moving, excess or obsolete.

Advertising expense was $0.6 $0.5 $0.4 September 30, 2019, 2018 2017, Management estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Any significant, unanticipated changes in product demand, technological developments or continued economic trends affecting the wireless infrastructure or telecommunications industries could have a significant impact on the value of the Company's inventory and operating results. Concentrations of risk The Company holds cash with one not Other financial instruments that potentially subject the Company to concentration of credit risk consist principally of trade receivables. Concentrations of credit risk with respect to trade receivables are limited because a large number of geographically diverse customers make up the Company’s customer base, thus spreading the trade credit risk. The Company controls credit risk through credit approvals, credit limits and monitoring procedures. The Company performs credit evaluations for all new customers but does not The Company had one 2019 12% no 2018 2017 10% $2.4 $2.9 $3.1 September 30, 2019, 2018 2017, not 10% one Employee stock-based awards Share-based payments to employees, including grants of employee stock options, are recognized in the consolidated financial statements based on their grant date fair value over the requisite service period. The Company determines the fair value of the options issued, using the Black-Scholes valuation model, and amortizes the calculated value over the vesting term of the stock options. Compensation expense for stock-based awards is included in the operating, selling, general and administrative expense section of the consolidated statements of operations. Earnings per share Basic earnings per share is computed by dividing the earnings available to common shareholders by the weighted average number of common shares outstanding for the year. Dilutive earnings per share include any dilutive effect of stock options and restricted stock. Fair value of financial instruments The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable, accrued expenses and other current liabilities approximate fair value due to their short maturities. The carrying value of the Company’s variable-rate line of credit approximates its fair value since the interest rate fluctuates periodically based on a floating interest rate.

Revenue from Contract with Customer [Text Block]	Note 2 On October 1, 2018, 2014 09, 606 no not Additionally, the Company provides services related to the installation and upgrade of technology on cell sites and the construction of new small cells for 5G The amount of revenue recognized reflects the consideration to which the Company expects to be entitled to receive in exchange for its products, repair services or wireless infrastructure services. The following steps are applied in determining the amount and timing of revenue recognition: 1. Identification of a contract with a customer is a sales arrangement involving a purchase order issued by the customer stating the goods or services to be transferred. Payment terms are generally due in net 30 90 not 2. Identification of performance obligations in the sales arrangement which is predominantly the promise to transfer goods, repair services, recycle items or wireless infrastructure services provided to the customer. 3. Determination of the transaction price is specified in the purchase order based on the product or services to be transferred or provided to the customer. Wireless infrastructure services transaction prices are based on the Master Service Agreement contracts between the Company and the wireless customers. 4. Allocation of the transaction price to performance obligations. Substantially all the contracts are single performance obligations and the allocated purchase price is the transaction price. 5. Recognition of revenue occurs upon the satisfaction of the performance obligation and transfer of control. Transfer of control by the Telco segment generally occurs at the point the Company ships the product from its warehouse locations. Transfer of control for the Wireless segment generally occurs over time as the Company performs services. To measure progress towards completion on performance obligations for which revenue is recognized over time the Company utilizes an input method based upon a ratio of direct costs incurred to date to management’s estimate of the total direct costs to be incurred on each contract. The Company has established the systems and procedures to develop the estimates required to account for performance obligations over time. These procedures include monthly review by management of costs incurred, progress towards completion, changes in estimates of costs yet to be incurred and execution by subcontractors. The Company’s principal sales are from Wireless services, sales of Telco equipment and Telco recycled equipment. Sales are primarily to customers in the United States. International sales are made by the Telco segment to customers in Central America, South America and, to a substantially lesser extent, other international regions that utilize the same technology which totaled approximately $2.4 $2.9 $3.1 September 30, 2019, 2018 2017, The Company’s customers include wireless carriers, wireless equipment providers, multiple system operators, resellers and direct sales to end-user customers.

Generally, billing occurs subsequent to revenue recognition, resulting in contract assets. However, the Company sometimes receives advances or deposits from customers before revenue is recognized, resulting in contract liabilities. Contract assets and contract liabilities are included in Unbilled revenue and Deferred revenue, respectively, in the consolidated balance sheets.

Receivable [Policy Text Block]	Accounts receivable Trade receivables are carried at original invoice amount less an estimate made for doubtful accounts. Management determines the allowance for doubtful accounts by regularly evaluating individual customer receivables and considering a customer’s financial condition, credit history and current economic conditions.

Inventory, Policy [Policy Text Block]	Inventor ies For the Telco segment, inventories consist of new, refurbished and used telecommunications equipment. Inventory is stated at the lower of cost or net realizable value. Cost is determined using the weighted-average method. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. For the Telco segment, the Company records an inventory reserve provision to reflect inventory at its estimated net realizable value based on a review of inventory quantities on hand, historical sales volumes and technology changes. These reserves are to provide for items that are potentially slow-moving, excess or obsolete.

Advertising Cost [Policy Text Block]	Advertising costs Advertising costs are expensed as incurred. Advertising expense was $0.6 $0.5 $0.4 September 30, 2019, 2018 2017,
Use of Estimates, Policy [Policy Text Block]	Management estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Any significant, unanticipated changes in product demand, technological developments or continued economic trends affecting the wireless infrastructure or telecommunications industries could have a significant impact on the value of the Company's inventory and operating results.
Concentration Risk, Credit Risk, Policy [Policy Text Block]	Concentrations of risk The Company holds cash with one not Other financial instruments that potentially subject the Company to concentration of credit risk consist principally of trade receivables. Concentrations of credit risk with respect to trade receivables are limited because a large number of geographically diverse customers make up the Company’s customer base, thus spreading the trade credit risk.

Share-based Payment Arrangement [Policy Text Block]	Employee stock-based awards Share-based payments to employees, including grants of employee stock options, are recognized in the consolidated financial statements based on their grant date fair value over the requisite service period. The Company determines the fair value of the options issued, using the Black-Scholes valuation model, and amortizes the calculated value over the vesting term of the stock options. Compensation expense for stock-based awards is included in the operating, selling, general and administrative expense section of the consolidated statements of operations.
Earnings Per Share, Policy [Policy Text Block]	Earnings per share Basic earnings per share is computed by dividing the earnings available to common shareholders by the weighted average number of common shares outstanding for the year. Dilutive earnings per share include any dilutive effect of stock options and restricted stock.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Fair value of financial instruments The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable, accrued expenses and other current liabilities approximate fair value due to their short maturities. The carrying value of the Company’s variable-rate line of credit approximates its fair value since the interest rate fluctuates periodically based on a floating interest rate.
