| DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | ' | |||||||||||
| Description of Business— Ruckus Wireless, Inc. (“Ruckus”) is a leading provider of carrier-class Wi-Fi solutions. Ruckus’s solutions, which it calls Smart Wi-Fi, are used by service providers and enterprises to solve network capacity and coverage challenges associated with the rapidly increasing traffic and number of users and client devices on wireless networks. Ruckus’s Smart Wi-Fi solutions offer carrier-class features and functionality such as enhanced reliability, consistent performance, extended range and massive scalability. Ruckus’s products include gateways, wireless local area network (“WLAN”) controllers and high performance access points. These products incorporate the Company’s patented and proprietary technologies, such as Smart Radio, Smart QoS, Smart Mesh and Smart Scale, to enable high performance, reliable, adaptive and high capacity connectivity in a wide range of challenging operating conditions faced by service providers and enterprises. | ||||||||||||
| Basis of Presentation— The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in Ruckus’s Annual Report on Form 10-K for the year ended December 31, 2013, filed on March 3, 2014. | ||||||||||||
| The condensed consolidated balance sheet as of December 31, 2013, included herein, was derived from the audited financial statements as of that date, but does not include all disclosures including notes required by GAAP. | ||||||||||||
| In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full year 2014 or any future period. | ||||||||||||
| Principles of Consolidation— The condensed financial statements include the accounts of Ruckus and its wholly owned subsidiaries (collectively, the “Company”). All intercompany balances and transactions have been eliminated in consolidation. | ||||||||||||
| Use of Estimates— The preparation of financial statements in conformity with GAAP in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Significant estimates and assumptions made by management include the determination of revenue recognition, allowance for doubtful accounts, goodwill and intangible valuation, the fair value of stock awards, inventory valuation, estimates of warranty liability and accounting for income taxes. Management bases its estimates on historical experience and also on assumptions that it believes are reasonable. Actual results could materially differ from those estimates. | ||||||||||||
| Summary of Significant Accounting Policies— There have been no material changes to our significant accounting policies as compared to those described in our Annual Report on Form 10-K for the year ended December 31, 2013. | ||||||||||||
| Recent Accounting Pronouncements— In May 2014, the Financial Accounting Standard Board (“FASB”) and International Accounting Standards Board (“IASB”) issued ASU 2014-09, Revenue from Contracts with Customers, a converged standard on revenue recognition. Some of the main areas of transition to the new standard include, among others, transfer of control (revenue is recognized when a customer obtains control of a good or service), allocation of transaction price based on relative standalone selling price (entities that sell multiple goods or services in a single arrangement must allocate the consideration to each of those goods or services), contract costs (entities sometimes incur costs, such as sales commissions or mobilization activities, to obtain or fulfill a contract), and disclosures (extensive disclosures are required to provide greater insight into both revenue that has been recognized, and revenue that is expected to be recognized in the future from existing contracts). This accounting standard will be effective for the Company beginning in the first quarter of 2017, with no early adoption permitted. This standard may be adopted using either a full retrospective application or a modified retrospective application, where the cumulative effect of initially adopting the standard is recognized as an adjustment to the opening balance of retained earnings. The Company is currently evaluating the impact of this accounting standard on its consolidated financial position, results of operations and cash flows. | ||||||||||||
| Concentrations of Credit Risk and Significant Customers— Financial instruments that subject the Company to significant concentrations of credit risk primarily consist of cash, cash equivalents, short-term investments and accounts receivable. The Company invests only in high credit quality instruments and maintains its cash, cash equivalents and available-for-sale investments in fixed income securities. Management believes that the financial institutions that hold the Company’s investments are financially sound and, accordingly, are subject to minimal credit risk. Deposits held with banks may exceed the amount of insurance provided on such deposits. The Company’s accounts receivable are primarily derived from distributors and service providers located in the Americas, Europe, and Asia Pacific. The Company generally does not require its customers to provide collateral to support accounts receivable. To reduce credit risk, management performs ongoing credit evaluations of its customers’ financial condition. The Company has recorded an allowance for doubtful accounts for those receivables management has determined to not be collectible. | ||||||||||||

| FAIR VALUE DISCLOSURE | ' | |||||||||||||||
| FAIR VALUE DISCLOSURE | ||||||||||||||||
| Assets and liabilities recorded at fair value in the condensed consolidated financial statements are categorized based upon the level of judgment associated with the inputs used to measure their fair value. The Company categorizes its financial instruments into a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). | ||||||||||||||||
| A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. There were no transfers between levels during the six months ended June 30, 2014. Hierarchical levels that are directly related to the amount of subjectivity associated with the inputs to the valuation of these assets or liabilities are as follows: | ||||||||||||||||
| Level 1 | Quoted prices (unadjusted) in active markets that are accessible at the measurement date for identical assets or liabilities. | |||||||||||||||
| Level 2 | Observable prices that are based on inputs not quoted on active markets, but corroborated by market data. | |||||||||||||||
| Level 3 | Unobservable inputs are used when little or no market data is available. | |||||||||||||||
| The Company’s assets that were measured at fair value by level within the fair value hierarchy were as follows (in thousands): | ||||||||||||||||

| On July 18, 2013, the Company acquired all of the outstanding equity interests of YFind Technologies Private Limited (“YFind”), a privately-held software company providing indoor positioning and real-time location-based analytics. The Company acquired YFind to obtain its technology and expertise in location-based services. The purchase consideration was $6.1 million, all of which was paid in cash. | ||||
| Former YFind employees who became the employees of the Company were granted 219,782 restricted stock units (“RSUs”) and 51,900 stock options under the Company's Amended & Restated 2012 Equity Incentive Plan (the “2012 Plan”). The equity awards vest between three and four years from when the employee was hired. The fair value of the equity awards of $3.6 million will be recognized as post-acquisition compensation expense over the requisite service period. The Company is also obligated to pay retention bonuses of up to $0.4 million to certain former YFind employees who became employees of the Company, over two years from the date of hire. Both the equity awards and the retention bonuses are subject to certain continued employment restrictions. For the three and six months ended June 30, 2014, the Company recorded compensation costs of $0.4 million and $0.7 million, respectively, in research and development expenses associated with the equity awards and the retention bonuses. | ||||

| Litigation— The Company is involved in legal proceedings, claims, and litigation arising in the ordinary course of business. Management is not currently aware of any matters that it expects will have a material adverse effect on the consolidated financial position, results of operations, or cash flows of the Company. | ||||||||||||||||
| For the six months ended June 30, 2014, the Company settled several patent litigation claims for a net gain of $0.8 million, which is included in general and administrative expense in the condensed consolidated statements of operations. The Company did not have material settlement gains or losses for the three months ended June 30, 2014, and three and six months ended June 30, 2013. | ||||||||||||||||
| Purchase Commitments— As of June 30, 2014, the Company had current purchase commitments of $18.1 million for inventory and specific contractual services. | ||||||||||||||||
| Indemnification Agreements— The Company indemnifies its directors for certain events or occurrences, subject to certain limits, while the director is or was serving at the Company’s request in such capacity. The term of the indemnification period is for the director’s term of service. The Company may terminate the indemnification agreements with its directors upon the termination of their services as directors of the Company, but termination will not affect claims for indemnification related to events occurring prior to the effective date of termination. The maximum amount of potential future indemnification is unlimited; however, the Company has a director insurance liability policy that limits its exposure. The Company believes the fair value of these indemnification agreements is minimal. The Company has also entered into customary indemnification agreements with each of its officers. | ||||||||||||||||
| The Company indemnifies its channel partners against certain claims alleging that the Company’s products (excluding custom products and/or custom support) infringe a patent, copyright, trade secret, or trademark, provided that a channel partner promptly notifies the Company in writing of the claim and such channel partner cooperates with the Company and grants the Company the authority to control the defense and any related settlement. | ||||||||||||||||
| The Company has not recorded any liabilities for these agreements as of June 30, 2014 and December 31, 2013. | ||||||||||||||||
| Reimbursement of Penalties— As of June 30, 2014, the Company held $5.0 million in escrow to secure an indemnification agreement. If triggered, the Company will indemnify a channel partner for reimbursement of penalties assessed under the Information Technology Act of India (“IT Act”). The IT Act specifies penalties for network service providers in the event of illegal or unauthorized use of computers, computer systems and data stored therein. In the event that Ruckus equipment is the cause of a network service provider breach, the Company is required to indemnify the channel partner, without limitation to the amount, for penalties reimbursed by the channel partner to the network service provider under the IT Act. The indemnification period is six years beginning from April 2013. To date no claims have been made under the IT Act, for which the Company would be potentially liable. | ||||||||||||||||
| Warranties— The Company offers a limited lifetime hardware warranty on its indoor WLAN products and a limited warranty for all other hardware products for a period of up to one year. The Company estimates the costs that may be incurred under its warranties and records a liability for products sold as a charge to cost of revenue. Estimates of future warranty costs are largely based on historical experience of product failure rates and material usage incurred in correcting product failures. The Company periodically assesses the adequacy of its recorded warranty liability and adjusts the amounts as necessary. | ||||||||||||||||

| The Company measures compensation expense for all stock-based payment awards, including stock options and RSUs granted to employees and purchases under the Company's Employee Stock Purchase Plan (“ESPP”), based on the estimated fair values on the date of the grant. The fair value of each stock option granted is estimated using the Black-Scholes option pricing model. The fair value of each RSU granted represents the closing price of the Company's common stock on the date of grant. The fair value of purchases under the Company's ESPP is calculated based on the closing price of the Company's stock on the date of grant and the value of put and call options estimated using the Black-Scholes option pricing model. Stock-based compensation is recognized on a straight-line basis over the requisite service period, net of estimated forfeitures. The forfeiture rate is based on an analysis of the Company’s actual historical forfeitures. | ||||||||||||||||
| The Company accounts for stock options issued to non-employees based on the fair value of the awards determined using the Black-Scholes option pricing model. The fair value of stock options granted to non-employees is re-measured as the stock options vest, and the resulting change in fair value, if any, is recognized in the Company’s condensed consolidated statement of operations during the period the related services are rendered. | ||||||||||||||||

| Basic net income per share is computed by dividing net income by the weighted-average number of common shares outstanding during the period. Diluted net income per share is computed by dividing net income by the weighted-average number of common shares outstanding, including potential dilutive common shares assuming the dilutive effect of outstanding stock awards using the treasury stock method. Under the treasury stock method, the amount the employee must pay for exercising stock awards, the amount of compensation cost for future service that the Company has not yet recognized, and the amount of tax benefits that would be recorded in additional paid-in capital when the award becomes deductible, are collectively assumed to be used to repurchase shares. | ||||||||||||||||

| INCOME TAXES | |
| The income tax expense of $2.7 million for the three months ended June 30, 2014 was primarily due to certain non-deductible stock-based compensation expenses, which caused the effective tax rate to exceed the statutory rate for the period. The income tax expense of $0.3 million for the three months ended June 30, 2013, consists of federal, foreign, and state income taxes. The effective tax rate for the three months ended June 30, 2013 is lower than the federal statutory rate primarily due primarily to certain stock compensation deductions. | |
| The income tax expense of $3.4 million for the six months ended June 30, 2014 was primarily due to certain non-deductible stock-based compensation expenses, which caused the effective tax rate to exceed the statutory rate for the period. The income tax benefit of $0.3 million for the six months ended June 30, 2013 primarily relates to the extension of the R&D credit by Congress in January 2013. | |
| The Company evaluates the realization of its deferred tax assets based on the expiration period of the asset, projections of future taxable income in the relevant tax jurisdiction, the effect of tax planning strategies, and other factors. Both positive and negative evidence is weighed using significant judgment. Based on an evaluation of these factors, the Company believes that the realization of its deferred tax assets is more likely than not and, therefore, a valuation allowance against its deferred tax assets is not required. In future periods, positive and negative evidence can change due to revised projections of future taxable income in the relevant jurisdictions and other factors listed above. If future circumstances require a valuation allowance to be recorded, there would be an increase in tax expense in the consolidated statements of operations without any change in net cash provided by operating activities in the consolidated statements of cash flows. |

| The Company operates in one industry segment selling gateways, controllers and access points along with related software and services. | ||||||||||||||||
| Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision making group, in deciding how to allocate resources and in assessing performance. The Company’s chief operating decision maker is its chief executive officer. The Company’s chief executive officer reviews financial information presented on a consolidated basis for purposes of allocating resources and evaluating financial performance. The Company has one business activity, and there are no segment managers who are held accountable for operations, operating results and plans for products or components below the consolidated unit level. Accordingly, the Company reports as a single operating segment. The Company and its chief executive officer evaluate performance based primarily on revenue in the geographic locations in which the Company operates. Revenue is attributed by geographic location based on the bill-to location of the Company’s customers. | ||||||||||||||||

| Description of Business— Ruckus Wireless, Inc. (“Ruckus”) is a leading provider of carrier-class Wi-Fi solutions. Ruckus’s solutions, which it calls Smart Wi-Fi, are used by service providers and enterprises to solve network capacity and coverage challenges associated with the rapidly increasing traffic and number of users and client devices on wireless networks. Ruckus’s Smart Wi-Fi solutions offer carrier-class features and functionality such as enhanced reliability, consistent performance, extended range and massive scalability. Ruckus’s products include gateways, wireless local area network (“WLAN”) controllers and high performance access points. These products incorporate the Company’s patented and proprietary technologies, such as Smart Radio, Smart QoS, Smart Mesh and Smart Scale, to enable high performance, reliable, adaptive and high capacity connectivity in a wide range of challenging operating conditions faced by service providers and enterprises. | ||||||||||||
| Basis of Presentation | ' | |||||||||||
| Basis of Presentation— The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in Ruckus’s Annual Report on Form 10-K for the year ended December 31, 2013, filed on March 3, 2014. | ||||||||||||
| The condensed consolidated balance sheet as of December 31, 2013, included herein, was derived from the audited financial statements as of that date, but does not include all disclosures including notes required by GAAP. | ||||||||||||
| In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full year 2014 or any future period. | ||||||||||||
| Principles of Consolidation | ' | |||||||||||
| Principles of Consolidation— The condensed financial statements include the accounts of Ruckus and its wholly owned subsidiaries (collectively, the “Company”). All intercompany balances and transactions have been eliminated in consolidation. | ||||||||||||
| Use of Estimates | ' | |||||||||||
| Use of Estimates— The preparation of financial statements in conformity with GAAP in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Significant estimates and assumptions made by management include the determination of revenue recognition, allowance for doubtful accounts, goodwill and intangible valuation, the fair value of stock awards, inventory valuation, estimates of warranty liability and accounting for income taxes. Management bases its estimates on historical experience and also on assumptions that it believes are reasonable. Actual results could materially differ from those estimates. | ||||||||||||
| Recent Accounting Pronouncements | ' | |||||||||||
| Recent Accounting Pronouncements— In May 2014, the Financial Accounting Standard Board (“FASB”) and International Accounting Standards Board (“IASB”) issued ASU 2014-09, Revenue from Contracts with Customers, a converged standard on revenue recognition. Some of the main areas of transition to the new standard include, among others, transfer of control (revenue is recognized when a customer obtains control of a good or service), allocation of transaction price based on relative standalone selling price (entities that sell multiple goods or services in a single arrangement must allocate the consideration to each of those goods or services), contract costs (entities sometimes incur costs, such as sales commissions or mobilization activities, to obtain or fulfill a contract), and disclosures (extensive disclosures are required to provide greater insight into both revenue that has been recognized, and revenue that is expected to be recognized in the future from existing contracts). This accounting standard will be effective for the Company beginning in the first quarter of 2017, with no early adoption permitted. This standard may be adopted using either a full retrospective application or a modified retrospective application, where the cumulative effect of initially adopting the standard is recognized as an adjustment to the opening balance of retained earnings. The Company is currently evaluating the impact of this accounting standard on its consolidated financial position, results of operations and cash flows | ||||||||||||
| Concentrations of Credit Risk and Significant Customers | ' | |||||||||||
| Concentrations of Credit Risk and Significant Customers— Financial instruments that subject the Company to significant concentrations of credit risk primarily consist of cash, cash equivalents, short-term investments and accounts receivable. The Company invests only in high credit quality instruments and maintains its cash, cash equivalents and available-for-sale investments in fixed income securities. Management believes that the financial institutions that hold the Company’s investments are financially sound and, accordingly, are subject to minimal credit risk. Deposits held with banks may exceed the amount of insurance provided on such deposits. The Company’s accounts receivable are primarily derived from distributors and service providers located in the Americas, Europe, and Asia Pacific. The Company generally does not require its customers to provide collateral to support accounts receivable. To reduce credit risk, management performs ongoing credit evaluations of its customers’ financial condition. The Company has recorded an allowance for doubtful accounts for those receivables management has determined to not be collectible. | ||||||||||||
