Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation	1. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. For further information, refer to the audited consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015. Nature of Operations PCTEL, Inc. (“PCTEL”, the “Company”, “we”, “ours”, and “us”) delivers P C T Segment Reporting PCTEL operates in two segments for reporting purposes, Connected Solutions and RF Solutions. The Company’s chief operating decision maker uses the profit and loss results through operating profit and identified assets for the Connected Solutions and RF Solutions segments to make operating decisions. Each segment has its own segment manager as well as its own engineering, sales and marketing, and operational general and administrative functions. All of the Company’s accounting and finance, human resources, IT and legal functions are provided on a centralized basis through the corporate function. The Company manages its balance sheet and cash flows centrally at the corporate level, with the exception of trade accounts receivable and inventory which is managed at the segment level. Each of the segment managers reports to and maintains regular contact with the chief operating decision maker to discuss operating activities, financial results, forecasts, or plans for the segment. Connected Solutions Segment Connected Solutions designs and delivers performance critical antennas and site solutions for wireless networks globally. The Company’s antennas and site solutions support networks worldwide, including SCADA for oil, gas and utilities, fleet management, industrial operations, health care, small cell and network timing deployment, defense, public safety, education, and broadband access. PCTEL's performance critical MAXRAD ® There are many competitors for antenna products, as the market is highly fragmented. Competitors include Laird (Cushcraft, Centurion, and Antennex products), Mobile Mark, Radiall/Larsen, Comtelco, Wilson, Commscope (Andrew products), and Kathrein, among others. The Company seeks out product applications that command a premium for product performance and customer service, and avoids commodity markets. PCTEL maintains expertise in several technology areas in order to be competitive in the antenna engineered site solutions market. These include radio frequency engineering, mobile antenna design and manufacturing, mechanical engineering, product quality and testing, and wireless network engineering. RF Solutions Segment RF Solutions develops and provides performance critical test equipment, software, and engineering services for wireless networks. The industry relies upon PCTEL to benchmark network performance, analyze trends, and optimize wireless networks. SeeGull ® On February 27, 2015, PCTEL acquired substantially all of the assets of, and assumed certain specified liabilities of, Nexgen Wireless, Inc. (“Nexgen”), pursuant to an Asset Purchase Agreement dated as of February 27, 2015. Nexgen provides a network analysis tool portfolio now known as SeeHawk ® PCTEL maintains expertise in several technology areas in order to be competitive in the scanning receiver and related engineering services market. These include radio frequency engineering, DSP engineering, manufacturing, mechanical engineering, product quality and testing, and wireless network engineering. Basis of Consolidation The condensed consolidated balance sheet as of March 31, 2016 and the condensed consolidated statements of operations, statements of comprehensive loss, and cash flows for the three months ended March 31, 2016 and 2015, respectively, are unaudited and reflect all adjustments of a normal recurring nature that are, in the opinion of management, necessary for a fair presentation of the interim period financial statements. The interim condensed consolidated financial statements are derived from the audited financial statements as of December 31, 2015. The unaudited interim condensed consolidated financial statements of the Company have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the U.S. have been condensed or omitted. The significant accounting policies followed by the Company are set forth within the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 (“the 2015 Form 10-K”). There were no changes in the Company’s significant accounting policies during the three months ended March 31, 2016. In addition, the Company reaffirms the use of estimates in the preparation of the financial statements as set forth in the 2015 Form 10-K. These interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in the 2015 Form 10-K. The results of operations for the period ended March 31, 2016 may not be indicative of the results for the period ending December 31, 2016. Foreign Operations The Company is exposed to foreign currency fluctuations due to its foreign operations and because products are sold internationally. The functional currency for the Company’s foreign operations is predominantly the applicable local currency. Accounts of foreign operations are translated into U.S. dollars using the exchange rate in effect at the applicable balance sheet date for assets and liabilities and average monthly rates prevailing during the period for revenue and expense accounts. Adjustments resulting from translation are included in accumulated other comprehensive income (loss), a separate component of shareholders’ equity. Gains and losses resulting from other transactions originally in foreign currencies and then translated into U.S. dollars are included in the condensed consolidated statement of operations. Net foreign exchange losses resulting from foreign currency transactions included in other income, net were $17 and $6 for the three months ended March 31, 2016 and 2015, respectively. Recent Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. ASU No. 2016-09 affects all entities that issue share-based payment awards to their employees. ASU No. 2016-09 simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows, including recognizing all excess tax benefits and tax deficiencies as income tax expense or benefit in the income statement rather than in additional paid-in capital. ASU No. 2016-09 is effective for financial statements issued for annual reporting periods beginning after December 15, 2016 and interim periods within those years. Earlier application is permitted. The Company is currently evaluating the impact the standard may have on its consolidated financial statements and related disclosures. In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842),” which requires lessees to recognize assets and liabilities for the rights and obligations created by most leases on their balance sheet. The guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted. ASU 2016-02 requires modified retrospective adoption for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. The Company is currently evaluating the impact the standard may have on its consolidated financial statements and related disclosures. In November 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes, to simplify the presentation of deferred income taxes. The amendments in this update require that deferred tax assets and liabilities be entirely classified as noncurrent within the statement of financial position. Effective December 31, 2015, the Company early adopted the balance sheet classification of deferred taxes on a prospective basis. The guidance requires deferred tax assets and liabilities to be classified as noncurrent rather than split between current and noncurrent. Approximately $1.8 million in current deferred tax assets was reclassified to long-term deferred tax assets at December 31, 2015. In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers” which introduces a new revenue recognition model in which an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing U.S. GAAP. This ASU also requires disclosures sufficient to enable users to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers, including qualitative and quantitative disclosures about contracts with customers, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. The FASB has voted to approve a one-year deferral of the effective date from January 1, 2017 to January 1, 2018, while allowing for early adoption as of January 1, 2017. The new accounting standard is expected to have an impact to the Company’s consolidated financial statements. The Company is currently evaluating the adoption method options and the impact of the new guidance on our consolidated financial statements.

Fair Value of Financial Instrum

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	2. Fair Value of Financial Instruments The Company follows accounting guidance for fair value measurements and disclosures, which establishes a fair value hierarchy that requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, a three-tier fair value hierarchy has been established, which prioritizes the inputs used in measuring fair value as follows: Level 1: inputs are unadjusted 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 active markets for similar assets and liabilities, quoted prices for identical or similar assets or liabilities 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 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. Cash equivalents are measured at fair value and investments are recognized at amortized cost in the Company’s financial statements. Accounts receivable and other investments are financial assets with carrying values that approximate fair value due to the short-term nature of these assets. Accounts payable is a financial liability with a carrying value that approximates fair value due to the short-term nature of these liabilities.

Cash And Cash Equivalents [Abstract]
Cash, Cash Equivalents and Investments	4. Cash, Cash Equivalents and Investments The Company’s cash and investments consisted of the following: March 31, December 31, 2016 2015 Cash $ 2,159 $ 6,077 Cash equivalents 2,292 978 Short-term investments 23,431 24,728 $ 27,882 $ 31,783 Cash and Cash equivalents At March 31, 2016, cash and cash equivalents included bank balances and investments with original maturities less than 90 days. At March 31, 2016 and December 31, 2015, the Company’s cash equivalents were invested in highly liquid AAA rated money market funds that are required to comply with Rule 2a-7 of the Investment Company Act of 1940. Such funds utilize the amortized cost method of accounting, seek to maintain a constant $1.00 per share price, and are redeemable upon demand. The Company restricts its investments in AAA money market funds to those invested 100% in either short-term U.S. government agency securities or bank repurchase agreements collateralized by these same securities. The fair values of these money market funds are established through quoted prices in active markets for identical assets (Level 1 inputs). The cash in the Company’s U.S. banks is insured by the Federal Deposit Insurance Corporation up to the insurable limit of $250. At March 31, 2016, the Company had $2.2 million in cash and $2.3 million in cash equivalents, and at December 31, 2015, the Company had $6.1 million in cash and $1.0 million in cash equivalents. The Company had $0.5 million and $1.3 million of cash and cash equivalents in foreign bank accounts at March 31, 2016 and December 31, 2015, respectively. The Company plans to repatriate its cash from its subsidiary in Israel during 2016 because we expect to cease operations of this subsidiary during 2016. The Company expects to incur incremental income tax of $0.1 million related to the repatriation of the funds from Israel. The Company does not expect the foreign currency exchange related to the repatriation of these funds to have a material impact on the financial statements. As of March 31, 2016, the Company has no intentions of repatriating the cash in its foreign bank accounts in the U.K. or China. If the Company decides to repatriate the cash in the foreign bank accounts, it may experience difficulty in doing so in a timely manner. The Company may also be exposed to foreign currency fluctuations and taxes if it repatriates these funds. The Company’s cash in its foreign bank accounts is not insured. Investments At March 31, 2016 and December 31, 2015, the Company’s short-term investments consisted of pre-refunded municipal bonds, U.S. government agency bonds, AA or higher rated corporate bonds, and certificates of deposit, all classified as held-to-maturity. At March 31, 2016, the Company had invested $7.0 million in AA rated or higher corporate bonds, $6.1 million in U.S. government agency bonds, $6.0 million in pre-refunded municipal bonds and $4.4 million in certificates of deposit . The income and principal from the pre-refunded municipal bonds are secured by an irrevocable trust of U.S. Treasury securities. The bonds have original maturities greater than 90 days and mature in less than one year. The Company’s bonds are recorded at the purchase price and carried at amortized cost. The net unrealized gains (losses) were $(8) and $1 at March 31, 2016 and December 31, 2015, respectively. Approximately 8% and 11% of the Company’s bonds were protected by bond default insurance at March 31, 2016 and December 31, 2015, respectively. At December 31, 2015, the Company had invested $7.6 million in AA rated or higher corporate bond funds, $7.5 million in pre-refunded municipal bonds and taxable bond funds, $7.0 million in U.S. government agency bonds, and $2.7 million in certificates of deposit. The Company categorizes its financial instruments within a fair value hierarchy according to accounting guidance for fair value. The fair value hierarchy is described under the Fair Value of Financial Instruments in Note 2. For the Level 2 investments, the Company uses quoted prices of similar assets in active markets. Cash equivalents and Level 1 and Level 2 investments measured at fair value were as follows: March 31, 2016 December 31, 2015 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Cash equivalents: Money market funds and other cash equivalents $ 2,294 $ 0 $ 0 $ 2,294 $ 978 $ 0 $ 0 $ 978 Investments: Corporate bonds 0 6,972 0 6,972 0 7,558 0 7,558 US government agency bonds 0 6,100 0 6,100 0 7,008 0 7,008 Pre-refunded municipal bonds 0 5,965 0 5,965 0 7,497 0 7,497 Certificates of deposit 4,400 0 0 4,400 2,666 0 0 2,666 Total $ 6,694 $ 19,037 $ 0 $ 25,731 $ 3,644 $ 22,063 $ 0 $ 25,707

Goodwill And Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets	5. Goodwill and Intangible Assets Goodwill There were no changes to goodwill during the three months ended March 31, 2016. The $3.3 million of goodwill on the balance sheet was recorded in February 2015 as part of the purchase accounting for the Nexgen acquisition and was assigned to the RF Solutions segment. For evaluation purposes, this goodwill is part of the products reporting unit within the RF Solutions segment. Because the Company’s market capitalization plus control premium was below its carrying value at March 31, 2016, the Company considered this deficit as a triggering event for evaluating goodwill for impairment. The Company performed a quantitative evaluation and determined no impairment was required. The Company will continue to monitor goodwill going forward. Intangible Assets The Company amortizes intangible assets with finite lives on a straight-line basis over the estimated useful lives, which range from one to eight years. Amortization expense was approximately $0.8 million and $0.7 million for the three months ended March 31, 2016 and 2015, respectively. For the three months ended March 31, 2016, $0.6 million of the intangible amortization was included in operating expenses and $0.2 million was included in cost of goods sold. For the three months ended March 31, 2015, the intangible amortization of $0.7 million was included in operating expenses. The summary of other intangible assets, net is as follows: March 31, 2016 December 31, 2015 Accumulated Net Book Accumulated Net Book Cost Amortization Value Cost Amortization Value Customer contracts and relationships $ 25,497 $ 19,075 $ 6,422 $ 25,497 $ 18,616 $ 6,881 Patents and technology 10,114 7,504 2,610 10,114 7,337 2,777 Trademarks and trade names 4,960 3,834 1,126 4,960 3,738 1,222 Other 2,743 2,292 451 2,743 2,245 498 $ 43,314 $ 32,705 $ 10,609 $ 43,314 $ 31,936 $ 11,378 The $0.8 million decrease in the net book value of intangible assets at March 31, 2016 compared to December 31, 2015 reflects amortization expense of $0.8 million recorded for the three months ended March 31, 2016. Because the first quarter results of the Company’s services reporting unit within the RF Solutions segment were below its plan and forecast, the Company reviewed its intangible assets for impairment by performing a test of recoverability. Based on this analysis, no impairment was required. Actual results in relation to the projections are the key factor in recoverability of the assets. If actual results do not meet the forecast, a future impairment may occur. The assigned lives and weighted average amortization periods by intangible asset category is summarized below: Intangible Assets Assigned Life Weighted Average Amortization Period Customer contracts and relationships 4 to 6 years 5.0 Patents and technology 3 to 6 years 4.5 Trademarks and trade names 3 to 8 years 4.7 Other 1 to 6 years 4.4 The Company’s scheduled amortization expense for 2016 and the next five years is as follows: Fiscal Year Amount 2016 $ 2,962 2017 $ 2,785 2018 $ 2,708 2019 $ 2,509 2020 $ 414

Balance Sheet Information	6. Balance Sheet Information Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are recorded at invoiced amount with standard net terms that range between 30 and 60 days. The Company extends credit to its customers based on an evaluation of a customer’s financial condition and collateral is generally not required. The Company maintains an allowance for doubtful accounts for estimated uncollectible accounts receivable. The allowance is based on the Company’s assessment of known delinquent accounts, historical experience, and other currently available evidence of the collectability and the aging of accounts receivable. The Company’s allowance for doubtful accounts was $0.3 million at March 31, 2016 and at December 31, 2015. The provision for doubtful accounts is included in sales and marketing expense in the condensed consolidated statements of operations. Inventories Inventories are stated at the lower of cost or market and include material, labor and overhead costs using the first-in, first-out (“FIFO”) method of costing. Inventories as of March 31, 2016 and December 31, 2015 were composed of raw materials, sub-assemblies, finished goods and work-in-process. The Company had consigned inventory with customers of $0.5 million and $0.7 million at March 31, 2016 and December 31, 2015, respectively. The Company records allowances to reduce the value of inventory to the lower of cost or market, including allowances for excess and obsolete inventory. Reserves for excess inventory are calculated based on our estimate of inventory in excess of normal and planned usage. Obsolete reserves are based on our identification of inventory where carrying value is above net realizable value. The allowance for inventory losses was $2.3 million at March 31, 2016 and $2.2 million at December 31, 2015. Inventories consisted of the following: March, 31 December 31, 2016 2015 Raw materials $ 10,585 $ 11,012 Work in process 931 917 Finished goods 5,963 5,667 Inventories, net $ 17,479 $ 17,596 Prepaid and Other Current Assets Prepaid assets are stated at cost and are amortized over the useful lives (up to one year) of the assets. Property and Equipment Property and equipment are stated at cost and are depreciated using the straight-line method over the estimated useful lives of the assets. The Company depreciates computer equipment over three to five years, office equipment, manufacturing and test equipment, and motor vehicles over five years, furniture and fixtures over seven years, and buildings over 30 years. Leasehold improvements are amortized over the shorter of the corresponding lease term or useful life. Depreciation expense and gains and losses on the disposal of property and equipment are included in cost of sales and operating expenses in the condensed consolidated statements of operations.

Business Combinations [Abstract]
Acquisitions	7. Acquisitions Business combinations are accounted for using the acquisition method of accounting. In general, the acquisition method requires acquisition-date fair value measurement of identifiable assets acquired, liabilities assumed, and non-controlling interests in the acquiree. The measurement requirements result in the recognition of the full amount of acquisition-date goodwill, which includes amounts attributable to non-controlling interests. Neither the direct costs incurred to effect a business combination nor the costs the acquirer expects to incur under a plan to restructure an acquired business may be included as part of the business combination accounting. As a result, those costs are charged to expense when incurred, except for debt or equity issuance costs, which are accounted for in accordance with other generally accepted accounting principles. Acquisition of Nexgen Wireless, Inc. On February 27, 2015, the Company acquired substantially all of the assets of, and assumed certain specified liabilities of, Nexgen Wireless, Inc., an Illinois corporation (“Nexgen”), pursuant to an Asset Purchase Agreement dated as of February 27, 2015 (the “Nexgen APA”) among PCTEL, Inc., Nexgen, Bhumika Thakkar 2012 Irrevocable Trust Number One, Bhumika Thakkar 2012 Irrevocable Trust Number Two, and Jigar Thakkar (collectively, such trusts and Mr. Thakkar are the “Nexgen Shareholders”), and Bhumika Thakkar (collectively with Nexgen and the Nexgen Shareholders, the “Nexgen Parties”). Nexgen provides a network analysis tool portfolio, and engineering services. Nexgen’s software product portfolio translates real-time network performance data into engineering actions to optimize operator performance and supports crowd-based, cloud-based data analysis to enhance network performance. The business provides performance engineering, specialized staffing, and trend analysis for carriers, infrastructure vendors, and neutral hosts for 2G, 3G, 4G, and LTE networks. The purchase consideration for the Nexgen business was $21.4 million, consisting of $18.25 million in cash paid at closing, $2.25 million held in escrow, an estimated $0.8 million excess working capital true-up to be paid in cash, and a contingency payment that was provisionally calculated with a fair value of $0.1 million. The contingent payment was dependent on the achievement of revenue-based goals pertaining to the acquired business for the period commencing on March 1, 2015 and ending on April 30, 2016. The purchase consideration paid in cash was provided from the Company’s existing cash. The Company incurred transaction costs of $0.8 million for the acquisition of Nexgen primarily related to investment banking, legal, and due diligence consulting services. The assets acquired from Nexgen consisted primarily of customer relationships, intellectual property (including trade names), working capital (accounts receivable, work in process, accounts payable and accrued liabilities), and fixed assets. The Nexgen Parties are bound by non-competition covenants under the Nexgen APA, which generally expire on February 27, 2019. The Company calculated the fair value of the customer relationships, trade names, and non-compete agreement assets acquired by using the present value of future discounted cash flows. For the new technology, the Company used the replacement cost method for its valuation. The intangible assets recorded have a weighted average amortization period of 5.0 years. As previously reported in the Company’s Current Report on Form 8-K filed with the SEC on April 14, 2015, on April 7, 2015, Samsung Electronics America, Inc., as successor in interest to Samsung Telecommunications America, LLC (“Samsung”), provided Nexgen and the Company with a final notice of Samsung’s election to terminate, effective April 30, 2015, the Contractor Services Agreement, dated May 2, 2012 (the “CSA”), by and between Samsung and Nexgen. On May 5, 2015, the Company and the Nexgen Parties entered into an Amendment to the Asset Purchase Agreement (the “Nexgen APA Amendment”) with the following principal terms: (a) Nexgen agreed to transfer to the Company previously excluded accounts receivable with an aggregate value of $0.8 million; (b) the aggregate amount potentially payable to the Nexgen Parties as contingent consideration was reduced from $2.0 million to $1.0 million; (c) the Company waived its right to seek additional indemnification from the Nexgen Parties for matters specified therein; (d) the parties directed that $2.25 million in escrowed funds potentially payable to the Nexgen Parties pursuant to the Nexgen APA be released to the Company; (e) Mr. Thakkar relinquished a portion of the equity awards previously granted to him; and (f) the Company released various potential claims against Nexgen and the Nexgen Parties with respect to the termination of the CSA and related matters. The measurement period for the revised amount commenced on January 1, 2016 and ends on December 31, 2016 and is dependent on software revenue-based goals pertaining to the acquired business. As of March 31, 2016 and December 31, 2015, respectively, the Company estimated that the contingent liability would be $0. The amendment terms were accounted for consistent with accounting for legal settlements, as there is not a clear and direct link between the settlement and the acquisition price. During June 2015, the Company received the cash from the escrow fund and the previously excluded accounts receivable. These amounts are recorded in Other Income, net in the condensed consolidated statements of operations. Approximately 78% of Nexgen’s revenue was related to the U.S. Sprint cellular network, contracted either with Samsung or Sprint directly. During due diligence, the Company modeled a likely range of future revenue and cash flow based on the high degree of customer concentration risk. While the terminated CSA represented a material portion of that revenue, the resulting total future revenue and cash flow remained within the lower range of the forecast model. The Company utilized the lower end of the forecast range in evaluating the fair value of the acquired assets. The purchase accounting related to the valuation of certain tangible and intangible assets was complete as of December 31, 2015. The valuation yielded goodwill of $3.3 million, of which $1.5 million was related to the assembled workforce. The goodwill is deductible for income tax purposes. The following is the allocation of the purchase price for the assets from Nexgen at the date of the acquisition as of December 31, 2015: Tangible assets: Accounts receivable $ 5,358 Prepaid and other assets 49 Deferred cost of sales 24 Fixed assets 43 Total tangible assets 5,474 Intangible assets: Customer relationships 8,117 Trade names 972 Technology 3,332 Backlog 162 Non-compete 583 Goodwill 3,332 Total intangible assets 16,498 Total assets 21,972 Accounts payable 200 Accrued liabilities 341 Total liabilities 541 Net assets acquired $ 21,431 A reconciliation of the assets acquired with the cash paid at closing is as follows: Net assets acquired $ 21,431 Due Nexgen - contingent liability (91 ) Due Nexgen - working capital adjustment (840 ) Cash paid at closing $ 20,500 The Company does not have any material relationship with Mr. Thakkar and the other Nexgen Parties other than in respect of the Nexgen APA, the Nexgen APA Amendment and the transactions provided for therein. Effective November 2015, Mr. Thakkar resigned from his role as the Company’s Vice President and Chief Technology Officer, Network Analytics. The Company assumed Nexgen’s existing lease for Nexgen’s offices in Schaumburg, Illinois and is currently operating the acquired business from that location. Effective March 2016, the Company exercised its right of early termination of the Schaumburg lease. The early termination is effective as of August 31, 2016. The Company will move the employees to its Bloomingdale office. The Nexgen services acquired in 2015 were integrated into the existing RF engineering services operation and the data analytics products were integrated in the RF scanner product line. The Company recognizes revenue for the engineering services under the completed performance method. For specialized staffing, the Company recognizes revenue as services are provided to the customer. The Company’s results for the three months ended March 31, 2015 include the operating results for March for the business acquired from Nexgen. The following unaudited pro forma financial information gives effect to the acquisition of the Nexgen business as if the acquisition had taken place on January 1, 2015. The pro forma financial information for Nexgen was derived from the historical accounting records of Nexgen. (unaudited) Three March 31, 2015 REVENUES $ 29,284 NET INCOME $ 63 NET INCOME PER SHARE 0.00 The pro forma results include adjustments for intangible amortization of $0.3 million for the three months ended March 31, 2015. The pro forma information is presented for illustrative purposes only and may not be indicative of the results that would have been obtained had the acquisition actually occurred on January 1, 2015, nor is it necessarily indicative of the Company’s future consolidated results of operations or financial position.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Stock-Based Compensation	8. Stock-Based Compensation The condensed consolidated statements of operations include $0.9 million and $0.5 million of stock compensation expense for the three months ended March 31, 2016 and 2015, respectively. Stock compensation expense for the three months ended March 31, 2016 consists of $0.7 million for restricted stock awards, $87 for stock option expenses and $47 for stock purchase plan expenses. Stock compensation expense for the three months ended March 31, 2015 consists of $0.2 million for restricted stock awards, $0.2 million for stock option expenses and $53 for stock purchase plan expenses. The Company did not capitalize any stock compensation expense during the three months ended March 31, 2016 or 2015. Total stock-based compensation is reflected in the condensed consolidated statements of operations as follows: Three Months Ended March 31, 2016 2015 Cost of revenues $ 131 $ 73 Research and development 167 115 Sales and marketing 145 158 General and administrative 416 155 Total $ 859 $ 501 Restricted Stock – Service Based The Company grants restricted shares as employee incentives. When service-based restricted stock is granted to employees, the Company records deferred stock compensation within additional paid in capital, representing the fair value of the common stock on the date the restricted shares are granted. The Company records stock compensation expense on a straight-line basis over the vesting period of the applicable service-based restricted shares. These grants vest over various periods, but typically vest over four years. The following table summarizes restricted stock activity for the three months ended March 31, 2016: Weighted Average Grant Date Shares Fair Value Unvested Restricted Stock Awards - December 31, 2015 1,050,172 $ 6.11 Shares awarded 346,800 5.61 Shares vested (93,538 ) 7.50 Shares cancelled (13,176 ) 7.56 Unvested Restricted Stock Awards - March 31, 2016 1,290,258 $ 5.86 The intrinsic value of service-based restricted shares that vested during the three months ended March 31, 2016, and 2015, was $0.7 million and $1.0 million, respectively. At March 31, 2016, total unrecognized compensation expense related to restricted stock was approximately $5.1 million, net of forfeitures to be recognized through 2020 over a weighted average period of 1.9 years. Restricted Stock Units – Service Based The Company grants restricted stock units as employee incentives. Restricted stock units are primarily granted to foreign employees for long-term incentive purposes. Employee restricted stock units are service-based awards and are amortized over the vesting period. At the vesting date, these units are converted to shares of common stock. The Company records expense on a straight-line basis for restricted stock units. The following table summarizes the restricted stock unit activity during the three months ended March 31, 2016: Weighted Average Grant Date Units Fair Value Unvested Restricted Stock Units - December 31, 2015 22,725 $ 5.65 Units awarded 15,000 5.61 Units vested (1,337 ) 7.25 Unvested Restricted Stock Units - March 31, 2016 36,388 $ 5.57 The intrinsic value of service-based restricted stock units that vested and were issued as shares during the three months ended March 31, 2016 and 2015 was $10 and $20, respectively. As of March 31, 2016, the unrecognized compensation expense related to the unvested portion of the Company’s restricted stock units was approximately $0.1 million, to be recognized through 2020 over a weighted average period of 1.5 years. Stock Options The Company grants stock options to purchase common stock as long-term incentives. The Company issues stock options with exercise prices no less than the fair value of the Company’s stock on the grant date. The Company grants new stock options with a seven-year life that contain installment vesting over a period of four years, 25% after one year, and monthly thereafter. Stock options may be exercised at any time prior to their expiration date or within ninety days of termination of employment, or such shorter time as may be provided in the related stock option agreement. A summary of the Company’s stock option activity for the three months ended March 31, 2016 is as follows: Weighted Average Options Exercise Outstanding Price Outstanding at December 31, 2015 1,220,442 $ 7.72 Expired or Cancelled (97,695 ) 7.88 Forfeited (35,936 ) 7.20 Outstanding at March 31, 2016 1,086,811 $ 7.73 Exercisable at March 31, 2016 840,019 $ 7.84 There were no exercises of stock options during the three months ended March 31, 2016. During the three months ended March 31, 2015, the Company received proceeds of $0.2 million from the exercise of 23,784 options. The intrinsic value of these options exercised was $31. The range of exercise prices for options outstanding and exercisable at March 31, 2016, was $5.50 to $11.00. The following table summarizes information about stock options outstanding under all stock option plans: Options Outstanding Options Exercisable Weighted Average Weighted- Weighted Range of Number Contractual Life Average Number Average Exercise Prices Outstanding (Years) Exercise Price Exercisable Exercise Price $ 5.50 -- $ 6.00 20,879 6.04 $ 5.91 3,236 $ 5.64 6.01 -- 6.50 16,267 3.04 6.23 14,847 6.23 6.51 -- 7.00 37,522 2.15 6.85 36,126 6.86 7.01 -- 7.50 658,844 4.00 7.17 506,563 7.17 7.51 -- 8.00 20,000 4.10 7.79 10,313 7.80 8.01 -- 8.50 87,728 5.68 8.11 26,138 8.16 8.51 -- 9.00 7,405 3.04 8.76 5,486 8.77 9.01 -- 9.50 181,485 0.49 9.19 181,255 9.20 9.51 -- 10.00 15,781 2.43 9.63 15,155 9.63 10.01 -- 11.00 40,900 0.22 10.64 40,900 10.64 $ 5.50 -- $ 11.00 1,086,811 3.34 $ 7.73 840,019 $ 7.84 The weighted average contractual life and intrinsic value at March 31, 2016, was the following: Weighted Average Contractual Life (years) Intrinsic Value Options Outstanding 3.34 $ 0 Options Exercisable 2.93 $ 0 The intrinsic value is based on the share price of $4.78 at March 31, 2016. The Company calculated the fair value of each option grant on the date of grant using the Black-Scholes option-pricing model using the following assumptions at March 31st: March 31, 2015 Dividend yield 2.5 % Risk-free interest rate 0.5 % Expected volatility 34 % Expected life (in years) 5.2 The fair value of each unvested option was estimated on the date of grant using the Black-Scholes option valuation model. The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options, which have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of highly subjective assumptions including the expected stock price volatility and expected option life. Because the Company’s employee stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, the existing models may not necessarily provide a reliable single measure of the fair value of the employee stock options. The dividend yield rate was calculated by dividing the Company’s annual dividend by the closing price on the grant date. The risk-free interest rate was based on the U.S. Treasury yields with remaining term that approximates the expected life of the options granted. The Company calculates the volatility based on a five-year historical period of the Company’s stock price. The Company incorporates a forfeiture rate based on historical data in the expense calculation. The expected life used for options granted is based on historical data of employee exercise performance. The Company records expense based on the grading vesting method. As of March 31, 2016, the unrecognized compensation expense related to the unvested portion of the Company’s stock options was approximately $0.2 million, net of estimated forfeitures to be recognized through 2019 over a weighted average period of 1.1 years. Performance-based Equity Awards The Company issued performance share units to executives in 2014 and 2015. The fair value of these performance share units was calculated based on the stock price on the date of grant. In June 2015, the Company’s Board of Directors approved the 2015 Long-Term Incentive Plan (“2015 LTIP”). Under the 2015 LTIP, shares can be earned by certain executive employees based upon achievement of revenue goals over a four-year period with a penalty if certain earnings levels are not maintained. The four-year period is divided into two interim periods (each an “Interim Period”), the first of which will end on December 31, 2016, and the second of which will end on December 31, 2018. At the award date, the number of shares that could be earned collectively by all participants at threshold and target were 212,000 and 424,000, respectively. Stock compensation expense is amortized over the performance period for these awards based on estimated achievement of the goals. No expense was recorded during the year ended December 31, 2015 for the 2015 LTIP because the Company does not believe it will meet the revenue threshold for the year ended December 31, 2016. In March 2014, the Company’s Board of Directors approved the 2014 Long-Term Incentive Plan (“2014 LTIP”). Under the 2014 LTIP, shares can be earned by certain executive employees based upon achievement of revenue goals over a four-year period with a penalty if certain profit levels are not maintained. The four-year period is divided into two interim periods (each an “Interim Period”), the first of which will end on December 31, 2015, and the second of which will end on December 31, 2017. The number of shares that could be earned collectively by all participants at threshold and target were 190,000 and 380,000, respectively. Stock compensation expense is amortized over the performance period for these awards based on estimated achievement of the goals. No expense was recorded for the 2014 LTIP because the Company did not meet the revenue threshold for the year ended 2015. Unvested awards of 162,000 related to the Interim Period ended December 31, 2015 were cancelled in December. The Company had 555,000 unvested performance units at March 31, 2016 and December 31, 2015. There was no activity during the quarter ended March 31, 2016. Employee Stock Purchase Plan (“ESPP”) The ESPP enables eligible employees to purchase common stock at the lower of 85% of the fair market value of the common stock on the first or last day of each offering period. Each offering period is approximately six months. The Company received proceeds of $0.4 million from the issuance of 78,415 shares under the ESPP in February 2016 and received proceeds of $0.4 million from the issuance of 57,293 shares under the ESPP in February 2015. Based on the 15% discount and the fair value of the option feature of this plan, this plan is considered compensatory. Compensation expense is calculated using the fair value of the employees’ purchase rights under the Black-Scholes model. The Company calculated the fair value of each employee stock purchase grant on the date of grant using the Black-Scholes option-pricing model using the following assumptions: March 31, 2016 2015 Dividend yield 4.2 % 2.5 % Risk-free interest rate 0.6 % 0.3 % Expected volatility 34 % 33 % Expected life (in years) 0.5 0.5 The dividend yield rate was calculated by dividing the Company’s annual dividend by the closing price on the grant date. The risk-free interest rate was based on the U.S. Treasury yields with a remaining term that approximates the expected life of the options granted. The dividend yield rate is calculated by dividing the Company’s annual dividend by the closing price on the grant date. The Company calculates the volatility based on a five-year historical period of the Company’s stock price. The expected life used is based on the offering period. Employee Withholding Taxes on Stock Awards For ease in administering the issuance of stock awards, the Company holds back shares of vested restricted stock awards and short-term incentive plan stock awards for the value of the statutory withholding taxes. For each individual receiving a share award, the Company redeems the shares it computes as the value for the withholding tax and remits this amount to the appropriate tax authority. For withholding taxes related to stock awards, the Company paid $0.2 million and $0.4 million during the three months ended March 31, 2016 and 2015, respectively. Stock Repurchases The Company repurchased 783,212 shares at an average price of $5.23 during the three months ended March 31, 2016. The Company repurchased 1,942,788 shares at an average price of $6.22 during the year ended December 31, 2015. In total, the Company repurchased 2,726,000 shares under share repurchase program during the past twelve months. At March 31, 2016, the Company had no shares that could still be repurchased under these programs.

The expiration lease term will remain the same at December 31, 2018 with a total remaining lease obligation of $149. There were no additional fees related to this lease amendment. Due to the transfer of certain manufacturing activities to the Company’s Tianjin, China facility, in October 2015 the Company entered into a new five-year lease for additional manufacturing space in Tianjin consisting of 22,163 square feet which expands our footprint in Tianjin to 44,289 square feet. This lease expires October 2020. The total lease obligation pursuant to this lease was $0.2 million. In May 2015 the Company entered into a new five-year, five month lease for office space in Englewood, Colorado, consisting of 4,759 square feet of office space for the services business. The total lease obligation pursuant to this lease was $0.6 million. The lease expires on October 31, 2020; however, during the first quarter 2016, the Company vacated this facility and is marketing this property for sublease. The office is located in an area with low vacancy rates. Pursuant to the Asset Purchase Agreement dated February 27, 2015 with Nexgen, the Company assumed Nexgen’s lease for office space in Schaumburg, Illinois consisting of 6,652 square feet.

Income Tax Disclosure [Abstract]
Income Taxes	11. Income Taxes The Company recorded an income tax benefit of $1.3 million for the three months ended March 31, 2016. The tax benefit for the three months ended March 31, 2016 differed from the statutory rate of 34% due to the combination of U.S. pretax losses and foreign pretax profits at lower tax rates. The Company recorded an income tax benefit of $19 for the three months ended March 31, 2015. The tax benefit for the three months ended March 31, 2015 differed from the statutory rate of 34% primarily because of state income taxes. The Company’s valuation allowance against its deferred tax assets was $0.6 million at March 31, 2016 and December 31, 2015. On a regular basis, the Company evaluates the recoverability of deferred tax assets and the need for a valuation allowance. Such evaluations involve the application of significant judgment. The Company considers multiple factors in its evaluation of the need for a valuation allowance. The Company’s long-term forecasts continue to support the realization of its deferred tax assets. However, the excess between the long-term income forecast and the income required to realize the deferred tax assets was lower at March 31, 2016 as compared to December 31, 2015. The Company’s domestic deferred tax assets have a ratable reversal pattern over 15 years. The carry forward rules allow for up to a 20 year carry forward of net operating losses (“NOL”) to future income that is available to realize the deferred tax assets. The combination of the deferred tax asset reversal pattern and carry forward period yields a 27.5 year average period over which future income can be utilized to realize the deferred tax assets. The Company’s gross unrecognized tax benefit was $0.8 million at March 31, 2016 and December 31, 2015. The Company files a consolidated federal income tax return, income tax returns with various states, and foreign income tax returns in various foreign jurisdictions. The Company’s U.S. federal and state tax returns remain subject to examination for 2012 and subsequent periods.

Basis of Consolidation	Basis of Consolidation The condensed consolidated balance sheet as of March 31, 2016 and the condensed consolidated statements of operations, statements of comprehensive loss, and cash flows for the three months ended March 31, 2016 and 2015, respectively, are unaudited and reflect all adjustments of a normal recurring nature that are, in the opinion of management, necessary for a fair presentation of the interim period financial statements. The interim condensed consolidated financial statements are derived from the audited financial statements as of December 31, 2015. The unaudited interim condensed consolidated financial statements of the Company have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the U.S. have been condensed or omitted. The significant accounting policies followed by the Company are set forth within the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 (“the 2015 Form 10-K”). There were no changes in the Company’s significant accounting policies during the three months ended March 31, 2016. In addition, the Company reaffirms the use of estimates in the preparation of the financial statements as set forth in the 2015 Form 10-K. These interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in the 2015 Form 10-K. The results of operations for the period ended March 31, 2016 may not be indicative of the results for the period ending December 31, 2016.
Foreign Operations	Foreign Operations The Company is exposed to foreign currency fluctuations due to its foreign operations and because products are sold internationally. The functional currency for the Company’s foreign operations is predominantly the applicable local currency. Accounts of foreign operations are translated into U.S. dollars using the exchange rate in effect at the applicable balance sheet date for assets and liabilities and average monthly rates prevailing during the period for revenue and expense accounts. Adjustments resulting from translation are included in accumulated other comprehensive income (loss), a separate component of shareholders’ equity. Gains and losses resulting from other transactions originally in foreign currencies and then translated into U.S. dollars are included in the condensed consolidated statement of operations. Net foreign exchange losses resulting from foreign currency transactions included in other income, net were $17 and $6 for the three months ended March 31, 2016 and 2015, respectively.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. ASU No. 2016-09 affects all entities that issue share-based payment awards to their employees. ASU No. 2016-09 simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows, including recognizing all excess tax benefits and tax deficiencies as income tax expense or benefit in the income statement rather than in additional paid-in capital. ASU No. 2016-09 is effective for financial statements issued for annual reporting periods beginning after December 15, 2016 and interim periods within those years. Earlier application is permitted. The Company is currently evaluating the impact the standard may have on its consolidated financial statements and related disclosures. In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842),” which requires lessees to recognize assets and liabilities for the rights and obligations created by most leases on their balance sheet. The guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted. ASU 2016-02 requires modified retrospective adoption for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. The Company is currently evaluating the impact the standard may have on its consolidated financial statements and related disclosures. In November 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes, to simplify the presentation of deferred income taxes. The amendments in this update require that deferred tax assets and liabilities be entirely classified as noncurrent within the statement of financial position. Effective December 31, 2015, the Company early adopted the balance sheet classification of deferred taxes on a prospective basis. The guidance requires deferred tax assets and liabilities to be classified as noncurrent rather than split between current and noncurrent. Approximately $1.8 million in current deferred tax assets was reclassified to long-term deferred tax assets at December 31, 2015. In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers” which introduces a new revenue recognition model in which an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing U.S. GAAP. This ASU also requires disclosures sufficient to enable users to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers, including qualitative and quantitative disclosures about contracts with customers, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. The FASB has voted to approve a one-year deferral of the effective date from January 1, 2017 to January 1, 2018, while allowing for early adoption as of January 1, 2017. The new accounting standard is expected to have an impact to the Company’s consolidated financial statements. The Company is currently evaluating the adoption method options and the impact of the new guidance on our consolidated financial statements.
