Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The accompanying unaudited consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. Intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Key estimates for the Company include: the recognition of revenue, in particular, estimated losses on long term construction contracts, allowance for doubtful accounts, inventory valuation, asset lives used in computing depreciation and amortization, valuation of intangible assets, valuation of contingent consideration, allowance for self-insurance health care claims incurred but not reported, valuation of stock options and other equity awards, particularly related to fair value estimates, accounting for income taxes, contingencies and litigation. While management believes that such estimates are reasonable when considered in conjunction with the financial position and results of operations taken as a whole, actual results could differ from those estimates, and such differences may be material to the consolidated financial statements.
Revenue Recognition	Revenue Recognition The Company recognizes revenue when: (i) persuasive evidence of a customer arrangement exists; (ii) the price is fixed or determinable; (iii) collectability is reasonably assured; and (iv) product delivery has occurred or services have been rendered. The Company recognizes revenue as services are performed and completed. The Company enters into contracts that require the construction and/or installation of specific units within a network system. Revenue from construction and installation contracts is recorded using the completed contract method of accounting. Under the completed contract method, revenues and costs from construction and installation projects are recognized only upon substantial completion of the project. Project costs typically include direct materials, labor and subcontractor costs, and indirect costs related to contract performance, such as indirect labor, supplies, and tools. Provisions for estimated losses on uncompleted contracts are recognized when it has been determined that a loss is probable. The Company also enters into contracts to provide engineering and integration services related to network architecture, transformation, reliability and performance. Revenues and costs from service contracts are generally recognized at the time the services are completed under the completed performance model. Services are generally performed under master or other services agreements and are billed on a contractually agreed price per unit of service on a work order basis. Services invoiced prior to the performance of the obligation are recorded in deferred revenue and recognized as the services are performed. The total amount of gross billings on uncompleted contracts as of December 31, 2015 and June 30, 2016 was $14.9 million and $14.0 million, respectively.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, which delayed the effective date of ASU 2014-09 by one year. Public business entities, certain not-for-profit entities, and certain employee benefit plans should apply the guidance in ASU 2014-09 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted only for annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. All other entities should apply the guidance in ASU 2014-09 for annual reporting periods beginning after December 15, 2018, and interim reporting periods within annual reporting periods beginning after December 15, 2019. All other entities may apply the guidance in ASU 2014-09 earlier for annual reporting period beginning after December 15, 2016, including interim reporting periods within that reporting period. All other entities also may apply the guidance in ASU 2014-09 earlier for annual reporting period beginning after December 15, 2016, and interim reporting periods within annual reporting periods beginning one year after the annual reporting period in which the entity first applies the guidance in ASU 2014-09. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting. In July 2015, the FASB issued ASU No. 2015-11, Simplifying the Measurement of Inventory (“ASU 2015-11”), which requires in scope inventory to be measured at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Subsequent measurement is unchanged for inventory measured using last-in, first-out (LIFO) or the retail inventory method. The amendments do not apply to inventory that is measured using LIFO or the retail inventory method. The amendments apply to all other inventory, which includes inventory that is measured using first-in, first-out (FIFO) or average cost. The ASU is effective for public business entities for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2016, and interim periods within fiscal years beginning after December 15, 2017. ASU 2015-11 requires prospective application, with earlier application permitted as of the beginning of an interim or annual reporting period. The Company is evaluating the effect that ASU 2015-11 will have on its consolidated financial statements and related disclosures. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”). ASU 2016-01, which provides guidance for the recognition, measurement, presentation and disclosure of financial assets and financial liabilities. ASU 2016-01 is effective for fiscal years, and for interim periods within those years, beginning after December 15, 2017 and, for most provisions, is effective using the cumulative-effect transition approach. Early application is permitted for certain provisions. The Company is currently evaluating the potential effect of this ASU on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Subtopic 842) (“ASU 2016-02”). ASU 2016-02 provides revised guidance for lease accounting and related disclosure requirements, including a requirement for lessees to recognize lease assets and lease liabilities for operating leases with a duration of greater than one year. Under the previous guidance, lessees were not required to recognize assets and liabilities for operating leases on the balance sheet. ASU 2016-02 is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted. Modified retrospective application is required for all relevant prior periods. The Company is currently evaluating the potential impact of this ASU on its consolidated financial statements. Upon adoption, the Company expects to recognize lease assets and liabilities for certain of its operating leases on the Company’s consolidated balance sheets. In March 2016, the FASB issued ASU No. 2016-09, Stock Compensation (Topic 718) - Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”). The new guidance was developed as part of the FASB's simplification initiative. The core principle of the ASU is that all income tax effects of awards are to be recognized in the statement of operations and comprehensive loss when the awards vest or are settled, it allows an employer to repurchase more of an employee's shares than it can currently for tax withholding purposes without triggering liability accounting, and allows an employer to make a policy election to account for forfeitures as they occur. ASU 2016-09 is effective for annual reporting periods, including interim periods within those annual periods, beginning after December 15, 2016. However early adoption is permitted. The Company anticipates the adoption in the effective period and is currently evaluating the effect, if any, that the ASU 2016-09 will have on the consolidated financial statements and related disclosures. In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing (“ASU 2016-10”). The amendments add further guidance on identifying performance obligations and also to improve the operability and understandability of the licensing implementation guidance. The amendments do not change the core principle of the guidance in Topic 606. The effective date and transition requirements for the amendments are the same as the effective date and transition requirements in Topic 606. Public entities should apply the amendments for annual reporting periods beginning after December 15, 2017, including interim reporting periods therein. Early application for public entities is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods therein. The Company is currently evaluating the potential impact of ASU 2016-10 on its consolidated financial statements. In May 2016, the FASB issued ASU No. 2016-12 Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients (“ASU 2016-12”). The amendments, among other things: (1) clarify the objective of the collectability criterion for applying paragraph 606-10-25-7; (2) permit an entity to exclude amounts collected from customers for all sales (and other similar) taxes from the transaction price; (3) specify that the measurement date for noncash consideration is contract inception; (4) provide a practical expedient that permits an entity to reflect the aggregate effect of all modifications that occur before the beginning of the earliest period presented when identifying the satisfied and unsatisfied performance obligations, determining the transaction price, and allocating the transaction price to the satisfied and unsatisfied performance obligations; (5) clarify that a completed contract for purposes of transition is a contract for which all (or substantially all) of the revenue was recognized under legacy GAAP before the date of initial application, and (6) clarify that an entity that retrospectively applies the guidance in Topic 606 to each prior reporting period is not required to disclose the effect of the accounting change for the period of adoption. The effective date of these amendments are the same date that Topic 606 is effective. Topic 606 is effective for public entities for annual reporting periods beginning after December 15, 2017, including interim reporting periods therein. The Company is currently evaluating the potential impact of ASU 2016-12 on its consolidated financial statements. Recent Accounting Pronouncements Adopted in 2016. In April 2015, the FASB issued ASU No. 2015-03, Simplifying the Presentation of Debt Issuance Costs (“ASU 2015-03”), to simplify the presentation of debt issuance costs. ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of the debt liability, consistent with debt discounts. The new standard is effective for the Company in the fiscal year beginning after December 15, 2015. The Company adopted ASU No. 2015-03 as of January 1, 2016. Prior period deferred financing costs of $10.4 million in the consolidated balance sheets as of December 31, 2015, has been reclassified to conform to the current period as required by the standard. See Note 7 to the Consolidated Financial Statements for further updates. In April 2015, the FASB issued ASU No. 2015-05, Intangibles - Goodwill and Other - Internal-Use Software: Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement (“ASU 2015-05”). ASU 2015-05 provides guidance for evaluating whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the software license element of the arrangement should be accounted for consistently with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the arrangement should be accounted for as a service contract. ASU 2015-05 does not change the accounting for service contracts. As a result of ASU 2015-05, all software licenses within the scope of the amendment will be accounted for consistently with other licenses of intangible assets. The new standard is effective for the Company in the fiscal year beginning after December 15, 2015. An entity can elect to adopt the amendments either: (1) prospectively to all arrangements entered into or materially modified after the effective date; or (2) retrospectively. The Company adopted ASU 2015-05 in the first quarter of 2016. The adoption of the new guidance did not have a material effect on the consolidated financial statements and related disclosures. In September 2015, the FASB issued ASU 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments (“ASU 2015-16”). ASU 2015-16 eliminates the requirement to retrospectively account for adjustments to provisional amounts within the measurement period recognized at the acquisition date in a business combination. ASU 2015-16 requires that these adjustments be recognized in the reporting period in which the adjustment amounts are determined and be calculated as if the accounting had been completed as of the acquisition date. ASU 2015-16 is effective prospectively for fiscal years, and for interim periods within those years, beginning after December 15, 2015. The Company adopted ASU 2015-16, however the adoption of the guidance did not have a material effect on the consolidated financial statements and related disclosures.
