Accounting Policies [Abstract]
Summary of Significant Accounting Principles and Policies	NOTE 1 - Summary of Significant Accounting Principles and Policies Basis of Presentation and Preparation Wireless Telecom Group, Inc., a New Jersey corporation, together with its subsidiaries (“we”, “us”, “our” or the “Company”), specializes in the design and manufacture of advanced radio frequency (“RF”) and microwave devices which enable the development, testing and deployment of wireless technology. The Company provides unique, highly customized and configured solutions which drive innovation across a wide range of traditional and emerging wireless technologies. Oura customers include wireless carriers, aerospace companies, defense contractors, military and government agencies, satellite communication companies, network equipment manufacturers, tower companies, semiconductor device manufacturers, system integrators, neutral host providers and medical device manufacturers. Our products include components, modules, instruments, systems and software used across the lifecycle of wireless connectivity and communication development, deployment and testing. Our customers use these products in relation to commercial infrastructure development, the expansion and upgrade of distributed antenna systems, deployment of small cell technology, use of medical devices and private long-term evolution (“LTE”) and 5G networks. In addition, the Company’s products are used in the development and testing of satellite communication systems, radar systems, semiconductor devices, automotive electronics and avionics. The accompanying consolidated financial statements include the accounts of Wireless Telecom Group, Inc., doing business as and operating under the trade name, Noisecom, and its wholly owned subsidiaries including Boonton Electronics Corporation (“Boonton”), Microlab/FXR LLC (“Microlab”), Holzworth Instrumentation, Inc. (“Holzworth”), Wireless Telecommunications Ltd. and CommAgility Limited (“CommAgility”). They have been prepared using accounting principles generally accepted in the United States (“U.S. GAAP”). All intercompany transactions and balances have been eliminated in consolidation. It is suggested that these interim consolidated financial statements be read in conjunction with the audited consolidated financial statements, and the notes thereto, included in the Company’s latest annual report (Form 10-K). The Company’s fiscal periods are based on the calendar year. Except as otherwise specified, references to “third quarter(s)” or “three months” indicate the Company’s three month period ended September 30, 2021 and September 30, 2020, and references to “year-end” indicate the fiscal year ended December 31, 2020. Consolidated Financial Statements In the opinion of management, the accompanying consolidated financial statements referred to above contain all necessary adjustments, consisting of normal accruals and recurring entries, which are necessary to fairly present the Company’s results for the interim periods being presented. The accounting policies followed by the Company are set forth in Note 1 to the Company’s consolidated financial statements included in its annual report on Form 10-K for the year ended December 31, 2020. Specific reference is made to that report since certain information and footnote disclosures normally included in financial statements in accordance with US GAAP have been reduced for interim periods in accordance with SEC rules. The results of operations for the three and nine months ended September 30, 2021 are not necessarily indicative of the results to be expected for the full year ending December 31, 2021. Critical Accounting Estimates The preparation of our consolidated financial statements requires the Company to make estimates and judgments that affect the reported amount of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amount of revenues and expenses for each period. We base our assumptions, judgements and estimates on historical experience and various other factors that we believe to be reasonable under the circumstances. At least quarterly, we evaluate our assumptions, judgments and estimates, and make changes as deemed necessary. The COVID-19 pandemic has negatively impacted regional and global economies, disrupted global supply chains and created significant volatility and disruption of financial markets. Although disruptions related to the COVID-19 pandemic did not impact our estimates and judgements as of the date of this report, it is reasonably possible that our accounting estimates and judgements may change as new events occur and additional information becomes available or is obtained. Furthermore, actual results could differ materially from our estimates as of the date of issuance of this Quarterly Report on Form 10-Q under different assumptions or conditions. For further information about our critical accounting estimates, see the discussion in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” under the heading “Critical Accounting Policies” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020. Concentration Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents and trade accounts receivable. Credit evaluations are performed on customers requiring credit over a certain amount. Credit risk is mitigated to a lesser extent through collateral such as letters of credit, bank guarantees or payment terms like cash in advance. For the three months ended September 30, 2021 no one customer accounted for greater than 10 10.32% 12.5% 10% One customer accounted for 12.2% 12.7% Fair Value of Financial Instruments Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. The accounting guidance establishes a three-tiered hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value: Level 1 - Quoted prices in active markets for identical assets or liabilities. Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The categorization of a financial instrument within the valuation hierarchy is based on the lowest level of input that is significant to the fair value measurement. The carrying amounts of the Company’s financial instruments, including cash, accounts receivable, accounts payable and accrued liabilities, approximate fair value due to their relatively short maturities. The Company’s term loan and revolving credit facility bear interest at a variable interest rate plus an applicable margin and, therefore, carrying amount approximates fair value. Contingent Consideration Under the terms of the Holzworth Share Purchase Agreement, the Company is required to pay additional purchase price in the form of deferred purchase price payments and an earnout based on Holzworth’s financial results for the years ended December 31, 2020 and 2021. The significant inputs used in this fair value estimate include estimated gross revenues and Adjusted EBITDA, as defined in the Holzworth Share Purchase Agreement, and scenarios for the earnout periods for which probabilities are assigned to each scenario to arrive at a single estimated outcome. The estimated outcome is then discounted based on the individual risk analysis of the liability. The contingent consideration liabilities are considered a Level 3 fair value measurement. The Company accounts for business acquisitions in accordance with ASC 805, Business Combinations Due to the anticipated better than expected financial performance of the Holzworth reporting unit for fiscal year 2021, the Company recorded an increase to the contingent consideration liabilities in the amount of $1.0 million in the three months ended September 30, 2021, which represents the Company’s best estimate of the earnout payable based on the expected financial results for the year ending December 31, 2021. This earnout will be payable in four equal installments in fiscal 2022. As of September 30, 2021, amounts due for the Holzworth deferred purchase price and earnout were $ 500,000 4.1

Business Combination and Asset Acquisition [Abstract]
Acquisition of Holzworth	NOTE 3 – Acquisition of Holzworth On February 7, 2020 the Company completed the acquisition of all of the outstanding shares of Holzworth. Holzworth instruments which include signal generators and phased noise analyzers are used by government labs, the semiconductor industry, and network equipment providers, among others, in research and automated test environments. Holzworth is a complimentary business for our Boonton and Noisecom brands with a common customer base and channel partners. The acquisition has been accounted for under the acquisition method of accounting in accordance with ASC 805, Business Combinations At closing, a portion of the purchase price was paid to the Sellers through the issuance of 347,319 500,000 During 2020, the Company paid $ 8.3 7.2 600,000 750,000 292,000 200,000 The Sellers earned a second deferred purchase price payment of $ 750,000 1.25 3.4 On February 19, 2021, the Company entered into the Second Amendment to Share Purchase Agreement (the “Second Amendment”) with Holzworth. The Second Amendment, among other things, converted the second deferred purchase price of $ 750,000 6.5% The payment date has been changed from March 31, 2021 to three equal installments of $ 250,000 Additionally, the parties amended the payment dates of the earnout consideration. The payment date of the Year 1 Earnout has been amended from March 31, 2021 to (i) six (6) equal quarterly installments of 10% of the Year 1 Earnout payable on the last business day of each calendar quarter between June 30, 2021 and September 30, 2022 and (ii) one (1) installment payment equal to 40% of the Year 1 Earnout on December 31, 2022.

Revenue

Revenue from Contract with Customer [Abstract]
Revenue	NOTE 7 – Revenue Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for promised goods or services. The Company’s performance obligations are satisfied either over time or at a point in time. Revenue from performance obligations that transferred at a point in time accounted for approximately 97 100 Nature of Products and Services Hardware The Company generally has one performance obligation in its arrangements involving the sales of radio frequency solutions, digital signal processing hardware, power meters, analyzers, noise/signal generators, phase noise analyzers and other components. When the terms of a contract include the transfer of multiple products, each distinct product is identified as a separate performance obligation. Generally, satisfaction occurs when control of the promised goods is transferred to the customer in exchange for consideration in an amount for which we expect to be entitled. Generally, control is transferred when legal title of the asset moves from the Company to the customer. We sell our products to a customer based on a purchase order, and the shipping terms per each individual order are primarily used to satisfy the single performance obligation. However, in order to determine when control has transferred to the customer, the Company also considers: ● when the Company has a present right to payment for the asset; ● when the Company has transferred physical possession of the asset to the customer; ● when the customer has the significant risks and rewards of ownership of the asset; and ● when the customer has accepted the asset. Software Arrangements involving licenses of software in the CommAgility brand may involve multiple performance obligations, most notably subsequent releases of the software. The Company has concluded that each software release in a multiple deliverable arrangement involving CommAgility software licenses is a distinct performance obligation and, accordingly, transaction price is allocated to each release when the customer obtains control of the software. Performance obligations that are not distinct at contract inception are combined. Specifically, with the Company’s sales of software, contracts that include customization may result in the combination of the customization services with the license as one distinct performance obligation and recognized over time. The duration of these performance obligations are typically one year or less. Services Arrangements involving calibration and repair services of the Company’s products are generally considered a single performance obligation and are recognized as the services are rendered. Shipping and Handling Shipping and handling activities performed after the customer obtains control are accounted for as fulfillment activities and recognized as cost of revenues. Significant Judgments For the Company’s more complex software and services arrangements, significant judgment is required in determining whether licenses and services are distinct performance obligations that should be accounted for separately or are not distinct and thus accounted for together. Further, in cases where we determine that performance obligations should be accounted for separately, judgment is required to determine the standalone selling price for each distinct performance obligation. Certain of the Company shipments include a limited return right. In accordance with Topic 606, the Company recognizes revenue net of expected returns. Contract Balances The timing of revenue recognition may differ from the timing of invoicing to customers and these timing differences result in contract assets (unbilled revenue) or contract liabilities (deferred revenue) on the Company’s consolidated balance sheet. The Company records unbilled revenue when revenue is recognized prior to invoicing, or deferred revenue when revenue is recognized subsequent to invoicing. Unbilled revenue was $ 179,000 260,000 691,000 924,000 Disaggregated Revenue We disaggregate our revenue from contracts with customers by product family and geographic location as we believe it best depicts how the nature, timing and uncertainty of our revenue and cash flows are affected by economic factors.

Income/(Loss) per share:
Earnings (Loss) Per Share	NOTE 9 – Earnings (Loss) Per Share Basic earnings (loss) per share is calculated by dividing net income (loss) available to common shareholders by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings (loss) per share is calculated by dividing net income (loss) available to common shareholders by the weighted-average number of common shares outstanding for the period and, when dilutive, potential shares from stock options using the treasury stock method, the weighted average number of unvested restricted shares, the weighted-average number of restricted stock units, the number of shares issuable under the terms of the Holzworth earnout and the weighted average number of warrants to purchase common stock outstanding for the period. Shares from stock options are included in the diluted earnings per share calculation only when options exercise prices are lower than the average market value of the common shares for the period presented. In periods with a net loss, the basic loss per share equals the diluted loss per share as all common stock equivalents are excluded from the per share calculation because they are anti-dilutive. In accordance with ASC 260, “Earnings Per Share”, the following table reconciles basic shares outstanding to fully diluted shares outstanding.

Accounting Policies [Abstract]
Basis of Presentation and Preparation	Basis of Presentation and Preparation Wireless Telecom Group, Inc., a New Jersey corporation, together with its subsidiaries (“we”, “us”, “our” or the “Company”), specializes in the design and manufacture of advanced radio frequency (“RF”) and microwave devices which enable the development, testing and deployment of wireless technology. The Company provides unique, highly customized and configured solutions which drive innovation across a wide range of traditional and emerging wireless technologies. Oura customers include wireless carriers, aerospace companies, defense contractors, military and government agencies, satellite communication companies, network equipment manufacturers, tower companies, semiconductor device manufacturers, system integrators, neutral host providers and medical device manufacturers. Our products include components, modules, instruments, systems and software used across the lifecycle of wireless connectivity and communication development, deployment and testing. Our customers use these products in relation to commercial infrastructure development, the expansion and upgrade of distributed antenna systems, deployment of small cell technology, use of medical devices and private long-term evolution (“LTE”) and 5G networks. In addition, the Company’s products are used in the development and testing of satellite communication systems, radar systems, semiconductor devices, automotive electronics and avionics. The accompanying consolidated financial statements include the accounts of Wireless Telecom Group, Inc., doing business as and operating under the trade name, Noisecom, and its wholly owned subsidiaries including Boonton Electronics Corporation (“Boonton”), Microlab/FXR LLC (“Microlab”), Holzworth Instrumentation, Inc. (“Holzworth”), Wireless Telecommunications Ltd. and CommAgility Limited (“CommAgility”). They have been prepared using accounting principles generally accepted in the United States (“U.S. GAAP”). All intercompany transactions and balances have been eliminated in consolidation. It is suggested that these interim consolidated financial statements be read in conjunction with the audited consolidated financial statements, and the notes thereto, included in the Company’s latest annual report (Form 10-K). The Company’s fiscal periods are based on the calendar year. Except as otherwise specified, references to “third quarter(s)” or “three months” indicate the Company’s three month period ended September 30, 2021 and September 30, 2020, and references to “year-end” indicate the fiscal year ended December 31, 2020.
Consolidated Financial Statements	Consolidated Financial Statements In the opinion of management, the accompanying consolidated financial statements referred to above contain all necessary adjustments, consisting of normal accruals and recurring entries, which are necessary to fairly present the Company’s results for the interim periods being presented. The accounting policies followed by the Company are set forth in Note 1 to the Company’s consolidated financial statements included in its annual report on Form 10-K for the year ended December 31, 2020. Specific reference is made to that report since certain information and footnote disclosures normally included in financial statements in accordance with US GAAP have been reduced for interim periods in accordance with SEC rules. The results of operations for the three and nine months ended September 30, 2021 are not necessarily indicative of the results to be expected for the full year ending December 31, 2021.
Critical Accounting Estimates	Critical Accounting Estimates The preparation of our consolidated financial statements requires the Company to make estimates and judgments that affect the reported amount of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amount of revenues and expenses for each period. We base our assumptions, judgements and estimates on historical experience and various other factors that we believe to be reasonable under the circumstances. At least quarterly, we evaluate our assumptions, judgments and estimates, and make changes as deemed necessary. The COVID-19 pandemic has negatively impacted regional and global economies, disrupted global supply chains and created significant volatility and disruption of financial markets. Although disruptions related to the COVID-19 pandemic did not impact our estimates and judgements as of the date of this report, it is reasonably possible that our accounting estimates and judgements may change as new events occur and additional information becomes available or is obtained. Furthermore, actual results could differ materially from our estimates as of the date of issuance of this Quarterly Report on Form 10-Q under different assumptions or conditions. For further information about our critical accounting estimates, see the discussion in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” under the heading “Critical Accounting Policies” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020.
Concentration Risk	Concentration Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents and trade accounts receivable. Credit evaluations are performed on customers requiring credit over a certain amount. Credit risk is mitigated to a lesser extent through collateral such as letters of credit, bank guarantees or payment terms like cash in advance. For the three months ended September 30, 2021 no one customer accounted for greater than 10 10.32% 12.5% 10% One customer accounted for 12.2% 12.7%
Fair Value of Financial Instruments	Fair Value of Financial Instruments Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. The accounting guidance establishes a three-tiered hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value: Level 1 - Quoted prices in active markets for identical assets or liabilities. Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The categorization of a financial instrument within the valuation hierarchy is based on the lowest level of input that is significant to the fair value measurement. The carrying amounts of the Company’s financial instruments, including cash, accounts receivable, accounts payable and accrued liabilities, approximate fair value due to their relatively short maturities. The Company’s term loan and revolving credit facility bear interest at a variable interest rate plus an applicable margin and, therefore, carrying amount approximates fair value.
Contingent Consideration	Contingent Consideration Under the terms of the Holzworth Share Purchase Agreement, the Company is required to pay additional purchase price in the form of deferred purchase price payments and an earnout based on Holzworth’s financial results for the years ended December 31, 2020 and 2021. The significant inputs used in this fair value estimate include estimated gross revenues and Adjusted EBITDA, as defined in the Holzworth Share Purchase Agreement, and scenarios for the earnout periods for which probabilities are assigned to each scenario to arrive at a single estimated outcome. The estimated outcome is then discounted based on the individual risk analysis of the liability. The contingent consideration liabilities are considered a Level 3 fair value measurement. The Company accounts for business acquisitions in accordance with ASC 805, Business Combinations Due to the anticipated better than expected financial performance of the Holzworth reporting unit for fiscal year 2021, the Company recorded an increase to the contingent consideration liabilities in the amount of $1.0 million in the three months ended September 30, 2021, which represents the Company’s best estimate of the earnout payable based on the expected financial results for the year ending December 31, 2021. This earnout will be payable in four equal installments in fiscal 2022. As of September 30, 2021, amounts due for the Holzworth deferred purchase price and earnout were $ 500,000 4.1
