Actual results could differ from those estimates. The Company believes the following critical accounting policies affect its more significant judgments and estimates used in the preparation of the financial statements. Significant estimates include the allowance for doubtful accounts, the useful life of plant and equipment, valuation of goodwill and intangible assets for impairment, deferred tax asset and valuation allowance, and assumptions used in Black-Scholes-Merton, or BSM, valuation methods, such as expected volatility, risk-free interest rate, and expected dividend rate. Cash The Company considers investments in highly liquid instruments with a maturity of three not February 28, 2019 May 31, 2018. Accounts Receivable Accounts receivable are reported at their outstanding unpaid principal balances net of allowances for doubtful accounts. The Company provides for allowances for doubtful receivables based on management’s estimate of uncollectible amounts considering age, collection history, and any other factors considered appropriate. The Company writes off accounts receivable against the allowance for doubtful accounts when a balance is determined to be uncollectible. As of February 28, 2019 May 31, 2018, $676,000 $0, Other Receivables Other receivables are included in other current assets on the balance sheet include amounts due under the various programs including clients that participate in the Spectrum Partners Program (“Spectrum Partners”) (See Note 11 February 28, 2019 May 31, 2018, not Fair Value of Financial Instruments The carrying value of cash, accounts receivable, other receivables, accounts payable and accrued expenses, payroll liabilities and advances approximate their fair values based on the short-term maturity of these instruments. As defined in ASC 820, 820 1 3 The three 820 ● Level 1 1 ● Level 2 1, 2 ● Level 3 may Earnings (Loss) Per Share (“EPS”) Basic EPS is computed by dividing net income (loss) by the weighted average number of shares of common stock outstanding. Diluted EPS includes the effect from potential issuance of common stock, such as stock issuable pursuant to the exercise of stock options and warrants and the assumed conversion of convertible notes. Dilutive EPS is computed by dividing net income (loss) by the sum of the weighted average number of common stock outstanding, and the dilutive shares, The following table summarizes the securities that were excluded from the diluted per share calculation because the effect of including these potential shares was antidilutive due to the Company’s net loss position even though the exercise price could be less than the average market price of the common shares: Nine months ended February 28, 2019 February 28, 2018 Convertible notes $ 3,177,943 $ - Stock options 7,112,500 6,520,834 Warrants 15,349,031 7,260,641 Potentially dilutive securities $ 25,639,474 $ 13,781,475 Three months ended February 28, 2019 February 28, 2018 Convertible notes $ 77,943 $ - Stock options - 6,520,834 Warrants 4,436,356 7,260,641 Potentially dilutive securities $ 4,514,299 $ 13,781,475 Stock-based Compensation In computing the impact, the fair value of each option and/or warrant is estimated on the date of grant based on the Black-Scholes options-pricing model utilizing certain assumptions for a risk-free interest rate; volatility; and expected remaining lives of the awards. The assumptions used in calculating the fair value of share-based payment awards represent management’s best estimates, but these estimates involve inherent uncertainties and the application of management judgment. As a result, if factors change and the Company uses different assumptions, the Company’s stock-based compensation expense could be materially different in the future. In addition, the Company is required to estimate the expected forfeiture rate and only recognize expense for those shares expected to vest. In estimating the Company’s forfeiture rate, the Company analyzed its historical forfeiture rate, the remaining lives of unvested options, and the amount of vested options as a percentage of total options outstanding. If the Company’s actual forfeiture rate is materially different from its estimate, or if the Company reevaluates the forfeiture rate in the future, the stock-based compensation expense could be significantly different from what the Company has recorded in the current period. Property and Equipment Property and equipment are recorded at cost. Depreciation is computed using straight-line method over the estimated useful lives of the related assets, generally three fifteen All site and tower costs are capitalized as construction-in-progress ("CIP"), as incurred.

Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, equity-based transactions and disclosure of contingent liabilities at the date of the financial statements and revenues and expenses during the reporting period. Actual results could differ from those estimates. The Company believes the following critical accounting policies affect its more significant judgments and estimates used in the preparation of the financial statements. Significant estimates include the allowance for doubtful accounts, the useful life of plant and equipment, valuation of goodwill and intangible assets for impairment, deferred tax asset and valuation allowance, and assumptions used in Black-Scholes-Merton, or BSM, valuation methods, such as expected volatility, risk-free interest rate, and expected dividend rate.

Receivable [Policy Text Block]	Accounts Receivable Accounts receivable are reported at their outstanding unpaid principal balances net of allowances for doubtful accounts. The Company provides for allowances for doubtful receivables based on management’s estimate of uncollectible amounts considering age, collection history, and any other factors considered appropriate. The Company writes off accounts receivable against the allowance for doubtful accounts when a balance is determined to be uncollectible. As of February 28, 2019 May 31, 2018, $676,000 $0,

Earnings Per Share, Policy [Policy Text Block]	Earnings (Loss) Per Share (“EPS”) Basic EPS is computed by dividing net income (loss) by the weighted average number of shares of common stock outstanding. Diluted EPS includes the effect from potential issuance of common stock, such as stock issuable pursuant to the exercise of stock options and warrants and the assumed conversion of convertible notes. Dilutive EPS is computed by dividing net income (loss) by the sum of the weighted average number of common stock outstanding, and the dilutive shares, The following table summarizes the securities that were excluded from the diluted per share calculation because the effect of including these potential shares was antidilutive due to the Company’s net loss position even though the exercise price could be less than the average market price of the common shares: Nine months ended February 28, 2019 February 28, 2018 Convertible notes $ 3,177,943 $ - Stock options 7,112,500 6,520,834 Warrants 15,349,031 7,260,641 Potentially dilutive securities $ 25,639,474 $ 13,781,475 Three months ended February 28, 2019 February 28, 2018 Convertible notes $ 77,943 $ - Stock options - 6,520,834 Warrants 4,436,356 7,260,641 Potentially dilutive securities $ 4,514,299 $ 13,781,475
Share-based Payment Arrangement [Policy Text Block]	Stock-based Compensation In computing the impact, the fair value of each option and/or warrant is estimated on the date of grant based on the Black-Scholes options-pricing model utilizing certain assumptions for a risk-free interest rate; volatility; and expected remaining lives of the awards. The assumptions used in calculating the fair value of share-based payment awards represent management’s best estimates, but these estimates involve inherent uncertainties and the application of management judgment. As a result, if factors change and the Company uses different assumptions, the Company’s stock-based compensation expense could be materially different in the future. In addition, the Company is required to estimate the expected forfeiture rate and only recognize expense for those shares expected to vest. In estimating the Company’s forfeiture rate, the Company analyzed its historical forfeiture rate, the remaining lives of unvested options, and the amount of vested options as a percentage of total options outstanding. If the Company’s actual forfeiture rate is materially different from its estimate, or if the Company reevaluates the forfeiture rate in the future, the stock-based compensation expense could be significantly different from what the Company has recorded in the current period.
Property, Plant and Equipment, Policy [Policy Text Block]	Property and Equipment Property and equipment are recorded at cost. Depreciation is computed using straight-line method over the estimated useful lives of the related assets, generally three fifteen All site and tower costs are capitalized as construction-in-progress ("CIP"), as incurred.

At the time of retirement or other disposition of property and equipment, the cost and accumulated depreciation will be removed from the accounts and the resulting gain or loss, if any, will be reflected in operations.
Research, Development, and Computer Software, Policy [Policy Text Block]	Software Development Costs The Company is developing software for a multi-layered system of application platforms that will utilize the GPS capabilities of the spectrum network and other leased network availability, to provide solutions for customers.
