Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2. Summary of Significant Accounting Policies During the three and nine months ended September 30, 2021, there have been no material changes to the Company’s significant accounting policies as described in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020, with the exception of the Company's adoption of Accounting Standards Codification (ASC) 842, Leases as discussed below. Restricted Cash As of September 30, 2021, the Company had $0.2 million in cash on deposit to secure certain lease commitments. Restricted cash is recorded in other assets in the Company’s consolidated balance sheet. Trade Accounts Receivable Trade accounts receivable is adjusted for all known uncollectible accounts. The policy for determining when receivables are past due or delinquent is based on the contractual terms agreed upon. Accounts are written off once all collection efforts have been exhausted. An allowance for doubtful accounts is established when, in the opinion of management, collection of the account is doubtful. The Company recorded an allowance for doubtful accounts of $20,000 as of September 30, 2021. No allowance for doubtful accounts was recorded as of December 31, 2020. Inventory The majority of the Company’s products are manufactured by third parties that retain ownership of the inventory until title is transferred to the customer at the shipping point. In some situations, the Company retains ownership of inventory which is held in third party contact manufacturing facilities. In certain instances, shipping terms are delivery-at-place and the Company is responsible for arranging transportation and delivery of goods ready for unloading at the named place. In those instances, the Company bears all risk involved in bringing the goods to the named place and records the related inventory in transit to the customer as inventory on the accompanying balance sheet. The Company also manufactures certain of its products at its facility located in Scottsdale, Arizona. Inventory is stated at the lower of cost or net realizable value. For items manufactured by the Company, cost is determined using the weighted average cost method. For items manufactured by third parties, cost is determined using the first-in, first-out (FIFO) method. Any adjustments to reduce the cost of inventories to their net realizable value are recognized in earnings in the current period. As of September 30, 2021, the Company’s inventories consisted of raw materials of $5.5 million, work in progress of $0.1 million and finished goods of $1.0 million. $2.2 million of the Company's inventory is located at contract manufacturers. As of December 31, 2020, inventories consisted of raw materials of $0.8 million and finished goods of $0.2 million. Provisions for excess and obsolete inventories are estimated based on product life cycles, quality issues, and historical experience and were $29,000 and $10,000 as of September 30, 2021 and December 31, 2020, respectively. Fair Value Measurements The carrying values of the Company’s financial instruments, including cash, trade accounts receivable, accounts payable, and accrued liabilities approximate their fair values due to the short maturity of these instruments. Fair value measurements are market-based measurements, not entity-specific measurements. Therefore, fair value measurements are determined based on the assumptions that market participants would use in pricing the asset or liability. The Company follows a three-level hierarchy to prioritize the inputs used in the valuation techniques to derive fair values. The basis for fair value measurements for each level within the hierarchy is described below:  Level 1: Quoted prices in active markets for identical assets or liabilities  Level 2: Quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs are observable in active markets.  Level 3: Valuations derived from valuation techniques in which one or more significant inputs are unobservable in active markets. Business Combinations The Company applies the provisions of ASC 805, Business Combinations, in accounting for its acquisitions. It requires the Company to recognize separately from goodwill the assets acquired and the liabilities assumed, at the acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the acqof inventory isuisition date fair values of the net assets acquired and the liabilities assumed. While the Company uses its best estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date, as well as the contingent consideration, where applicable, its estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, the Company records adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the consolidated statements of operations. In addition, uncertain tax positions and tax-related valuation allowances assumed, if any, in connection with a business combination are initially estimated as of the acquisition date. The Company re-evaluates these items quarterly based upon facts and circumstances that existed as of the acquisition date with any adjustments to the preliminary estimates being recorded to goodwill if identified within the measurement period. Subsequent to the end of the measurement period or final determination of the estimated value of the tax allowance or contingency, whichever comes first, changes to these uncertain tax positions and tax related valuation allowances will affect the income tax provision (benefit) in the consolidated statements of operations and could have a material impact on the results of operations and financial position. Revenue Recognition Effective January 1, 2019, the Company adopted Financial Accounting Standards Board (FASB) Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers, and the related amendments, which are codified into ASC 606, Revenue from Contracts with Customers, using the modified retrospective method. The Company generates revenue mainly from the sale of wireless connectivity solutions and technologies. A portion of revenue is generated from service agreements and data subscription plans with certain customers. The revenue generated from service contracts and data subscription plans is insignificant. The Company recognizes revenue to depict the transfer of control of the promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled for those goods or services. Control passes to the customers either when the products are shipped to or received by the customer, based on the terms of the specific agreement with the customer. Revenue from Nimbelink's data subscription plans is recognized over the period of the subscription. The Company records revenue based on a five-step model in accordance with ASC 606 whereby the company (i) identifies the contract(s) with the customer, (ii) identifies the performance obligations in the contract, (iii) determines the transaction price, (iv) allocates the transaction price to the performance obligation(s) in the contract and (v) recognizes the revenue when (as) the entity satisfies performance obligations. The Company only applies the five-step model when it is probable that the entity will collect substantially all of the consideration it is entitled to in exchange for the goods or services it transfers to the customer. For product sales, each purchase order, along with existing customer agreements, when applicable, represents a contract from a customer and each product sold represents a distinct performance obligation. The contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. The majority of the Company’s revenue is recognized on a “point-in-time” basis when control passes to the customer. The revenue from service contracts and data subscription plans is recognized “over time”. A portion of the Company’s sales is made through distributors under agreements which allow for pricing credits and/or rights of return under certain circumstances. A reserve for potential rights of return from distributors of $14,000 was recorded as of September 30, 2021. No reserve for potential return rights of return from distributors was recorded as of December 31, 2020. The Company’s contracts with customers do not typically include extended payment terms. Payment terms vary by contract and type of customer and generally range from 30 to 120 days from delivery. The Company provides assurance-type warranties on all product sales ranging from one to two years. The Company accrues for the estimated warranty costs at the time of sale based on historical warranty experience plus any known or expected changes in warranty exposure. The Company has recorded a warranty reserve of $15,000 as of September 30, 2021 and $10,000 as of December 31, 2020. Although customers may place orders for products that are delivered on multiple dates in different quarterly reporting periods; orders are typically scheduled within one year from the order date. The Company has opted to not disclose the portion of revenues allocated to partially unsatisfied performance obligations, which represent products to be shipped within 12 months under open customer purchase orders, at the end of the current reporting period as allowed under ASC 606. The Company has also elected to record sales commissions when incurred, pursuant to the practical expedient under ASC 340, as the period over which the sales commission asset that would have been recognized is less than one year. Shipping and handling costs are immaterial and reported in operating expenses in the condensed consolidated statement of operations. There were no contract assets as of September 30, 2021 and December 31, 2020. As of September 30, 2021 and December 31, 2020, the Company recorded $87,000 and $19,000 of contract liabilities, respectively. Recently Adopted Accounting Pronouncements In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which requires lessees to recognize most leases on their balance sheets as lease liabilities, representing a liability to make lease payments, and corresponding right-of-use assets representing its right to use the underlying asset. The Company adopted the new accounting standard using the modified retrospective transition option as of the effective date on January 1, 2021. The adoption of this standard had a material impact on the Company's condensed consolidated balance sheets. The adoption did not have an impact on the Company's consolidated statements of operations. See Note 10 for disclosures related to the adoption of this standard. In December 2019, the FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes, as part of its initiative to reduce complexity in accounting standards. The amendments in the ASU include removing exceptions to incremental intraperiod tax allocation of losses and gains from different financial statement components, exceptions to the method of recognizing income taxes on interim period losses, and exceptions to deferred tax liability recognition related to foreign subsidiary investments. In addition, the ASU requires that entities recognize franchise tax based on an incremental method and requires an entity to evaluate the accounting for step-ups in the tax basis of goodwill as inside or outside of a business combination. Based on the Company’s emerging growth company status the amendments in the ASU are effective for fiscal years beginning after December 15, 2020, and interim periods within fiscal years beginning after December 15, 2021. The Company has adopted this standard as of January 1, 2021. The adoption of this standard did not have a material impact on the Company's consolidated financial statements. Recently Issued Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments. This standard changes the methodology for measuring credit losses on financial instruments and the timing of when such losses are recorded. In December 2019, the FASB issued ASU 2019-10, Effective Dates which updated the effective dates of adoption of ASU 2016-13. ASU 2016-13 is effective, for Smaller Reporting Companies, for annual and interim periods in fiscal years beginning after December 15, 2022. Companies are required to adopt the standard using a modified retrospective adoption method. The Company continues to evaluate the impact of the standard on its consolidated financial statements. In May 2019, the FASB issued ASU 2019-05, Financial Instruments-Credit Losses (Topic 326), Targeted Transition Relief, which provides entities that have certain instruments within the scope of ASC 326-20, Financial Instruments-Credit Losses-Measured at Amortized Cost, with an option to irrevocably elect the fair value option for eligible instruments. The effective date and transition methodology for this standard are the same as in ASU 2016-13. The Company continues to evaluate the impact of the standard on its consolidated financial statements. In April 2021, the FASB issued ASU 2021-04, Earnings Per Share (Topic 260), Debt—Modifications and Extinguishments (Subtopic 470-50), Compensation—Stock Compensation (Topic 718), and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40), Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options. This guidance clarifies and reduces diversity in an issuer’s accounting for modifications or exchanges of freestanding equity-classified written call options due to a lack of explicit guidance in the FASB Codification. The ASU 2021-04 is effective for all entities for fiscal years beginning after December 15, 2021. Early adoption is permitted. The Company is currently evaluating the impact of adopting ASU 2021-04 on its consolidated financial statements.

Recently Issued Accounting Pronouncements

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments. This standard changes the methodology for measuring credit losses on financial instruments and the timing of when such losses are recorded. In December 2019, the FASB issued ASU 2019-10, Effective Dates which updated the effective dates of adoption of ASU 2016-13. ASU 2016-13 is effective, for Smaller Reporting Companies, for annual and interim periods in fiscal years beginning after December 15, 2022. Companies are required to adopt the standard using a modified retrospective adoption method. The Company continues to evaluate the impact of the standard on its consolidated financial statements.

In May 2019, the FASB issued ASU 2019-05, Financial Instruments-Credit Losses (Topic 326), Targeted Transition Relief, which provides entities that have certain instruments within the scope of ASC 326-20, Financial Instruments-Credit Losses-Measured at Amortized Cost, with an option to irrevocably elect the fair value option for eligible instruments. The effective date and transition methodology for this standard are the same as in ASU 2016-13. The Company continues to evaluate the impact of the standard on its consolidated financial statements.

In April 2021, the FASB issued ASU 2021-04, Earnings Per Share (Topic 260), Debt—Modifications and Extinguishments (Subtopic 470-50), Compensation—Stock Compensation (Topic 718), and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40), Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options. This guidance clarifies and reduces diversity in an issuer’s accounting for modifications or exchanges of freestanding equity-classified written call options due to a lack of explicit guidance in the FASB Codification. The ASU 2021-04 is effective for all entities for fiscal years beginning after December 15, 2021. Early adoption is permitted. The Company is currently evaluating the impact of adopting ASU 2021-04 on its consolidated financial statements.
