| Significant Accounting Policies [Abstract] | |||||||||||||||||
| Business Combinations Policy [Policy Text Block] |
Business Combinations
The Company applies the guidance of ASC topic 805, Business Combinations. This guidance requires the acquiring entity in a business combination to recognize the full fair value of assets acquired and liabilities assumed in transactions; established the acquisition date fair value as the measurement objective for all assets acquired and liabilities assumed; requires expensing of transaction and restructuring costs; and required the acquirer to disclose the information needed to evaluate and understand the nature and financial effect of the business combination.

| Cash and Cash Equivalents, Policy [Policy Text Block] |
Cash and Cash Equivalents
|
||||||||||||||||
| Short-term Investment, Policy [Policy Text Block] |
Short-term Investments
Certificates of deposit held for investment with an original maturity greater than 90 days are carried at cost and reported as Short-term investments on the Consolidated Balance Sheets. The certificates of deposit are not debt securities. The Company also invests in debt instruments consisting of pre-refunded municipal bonds. The income and principal from these pre-refunded bonds are secured by an irrevocable trust holding U.S Treasury securities. The bonds have original maturities of greater than 90 days, but have remaining maturities of less than one year. The pre-refunded municipal bonds are classified as held-to-maturity and are carried at amortized cost.
|
||||||||||||||||
| Accounts Receivable, Policy [Policy Text Block] |
Accounts Receivable
Trade accounts receivable are recorded at the invoiced amount and typically do not bear interest. The Company provides allowances for doubtful accounts related to accounts receivable for estimated losses resulting from the inability of its customers to make required payments. The Company takes into consideration the overall quality of the receivable portfolio along with specifically identified customer risks.
|
||||||||||||||||
| Concentration Risk, Credit Risk, Policy [Policy Text Block] |
Concentrations of Credit Risk
Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash equivalents, short-term investments, and trade receivables. The Company currently invests its excess cash in money market funds, certificates of deposit and debt investments consisting of pre-refunded municipal bonds that are secured by an irrevocable trust holding U.S. Treasury securities.

| Earnings Per Share, Policy [Policy Text Block] |
Earnings (Loss) per Share
The computation of basic net income (loss) per share is computed using the weighted-average number of common shares outstanding during the period. Diluted net income per share includes the number of additional common shares that would have been outstanding if the dilutive potential shares had been issued. In periods with a net loss, all common stock equivalents are excluded from the per share calculation; therefore, the basic loss per share equals the diluted loss per share.

| Inventory, Policy [Policy Text Block] |
Inventories
Inventories are stated at the lower of first-in, first-out (“FIFO”) cost or market value.
|

| prepaid expenses policy text block [Policy Text Block] |
Prepaid Expenses and Other Current Assets
Prepaid and current assets generally consisting of prepaid product royalty, prepaid maintenance agreements and prepaid rent, which are amortized as expense generally over the term of the underlying contract or estimated product life.
|
||||||||||||||||
| Property, Plant and Equipment [Table Text Block] |
Property and Equipment
Property and equipment are stated at cost, net of depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, or for leasehold improvements, the shorter of the remaining lease term or the estimated useful life. Expenditures for major renewals and improvements that extend the useful life of property and equipment are capitalized. The following table shows estimated useful lives of property and equipment, as follows:

| Goodwill and Intangible Assets, Policy [Policy Text Block] |
Goodwill and Other Intangibles
Goodwill is not amortized, but it is tested for impairment at the reporting unit level by first performing a qualitative approach to test goodwill for impairment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If it is concluded that this is the case, it is necessary to perform the two-step, quantitative, goodwill impairment test. Otherwise, the two-step goodwill impairment test is not required.
Goodwill and indefinite-lived intangible assets are reviewed for impairment at least annually or when an event occurs or circumstances change between annual tests that would more likely than not reduce the fair value of the reporting unit below its carrying value. The Company performs its annual impairment test in the fourth quarter of each fiscal year and begins with a qualitative assessment to determine if it is more likely than not that the fair value of a reporting unit is less than its carrying value.

| Revenue Recognition, Policy [Policy Text Block] |
Revenue Recognition and Deferred Revenue
The Company records revenue from sales transactions when title and risk of loss are passed to the customer, there is persuasive evidence of an arrangement for sale, delivery has occurred and/or services have been rendered, the sales price is fixed or determinable, and collectability is reasonably assured.
Revenue recognition on equipment where software is incidental to the product as a whole, or where software is essential to the equipment’s functionality and falls under software accounting scope exceptions, generally occurs when products are shipped, risk of loss has transferred to the customer, objective evidence exists that customer acceptance provisions have been met, no significant obligations remain, collection is reasonably assured and warranty can be estimated.
Where multiple element arrangements exist, fair value of each element is established using the relative selling price method, which requires the Company to use vendor-specific objective evidence (“VSOE”), reliable third-party objective evidence (“TPE”) or management’s best estimate of selling price, in that order.

||||||||||||||||
| Shipping and Handling Cost, Policy [Policy Text Block] |
Shipping and Handling
Freight billed to customers is recorded as revenue.
|
||||||||||||||||
| Product Warranties, Policy [Policy Text Block] |
Product Warranties
Most of the Company’s products carry a limited warranty of up to seven years. The Company accrues for estimated warranty costs as products are shipped based on historical sales and cost of repair or replacement trends relative to sales.
|
||||||||||||||||
| Research and Development Expense, Policy [Policy Text Block] |
Research and Development Costs
Engineering and product research and development costs are charged to expense as incurred.
|
||||||||||||||||
| Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block] |
Stock-based Compensation
The Company recognizes stock-based compensation expense for all employee stock-based payments based upon the fair value on the award’s grant date over the requisite service period. Determining the fair value of equity-based options requires the Company to estimate the expected volatility of its stock, the risk-free interest rate, expected option term, expected dividend yield and expected forfeitures.
|
||||||||||||||||
| Fair Value Measurement, Policy [Policy Text Block] |
Fair Value Measurements
The Company accounts for the fair value of assets and liabilities in accordance with ASC topic 820, Fair Value Measurements and Disclosures (“ASC 820”). ASC 820 defines fair value and establishes a framework for measuring fair value as required by other accounting pronouncements.

||||||||||||||||
| Foreign Currency Transactions and Translations Policy [Policy Text Block] |
Foreign Currency Translation and Transaction
The Company’s primary foreign currency exposure is to changes in exchange rates for the U.S. dollar versus the Canadian dollar and the related effects on receivables and payables denominated in Canadian dollars. The Company’s foreign subsidiary, Noran Tel, is located in Canada. In the quarter ended September 30, 2012, the Company completed the relocation of the production of products from Canada to its headquarters in Aurora, IL. Noran Tel has five remaining employees located in Canada and is now focused on the development of power distribution products and the sale of Westell products in Canada. Noran Tel is funded by the U.S. operations. On August 1, 2012, the functional currency for Noran Tel was changed from the Canadian dollar to the U.S. dollar. The Company will continue to have revenue and expenses denominated in Canadian currency, but it is no longer exposed to gains and losses from fluctuations affecting net investments and earnings of Noran Tel. The Canadian entity revenues, which are denominated in U.S. dollars, are solely from its parent, Westell Inc., located in the U.S. As of March 31, 2013, and March 31, 2012, the balance in the cumulative foreign currency translation adjustment account, which is a component of stockholders’ equity, was an unrealized gain of $0.6 million and $0.6 million, respectively.
The Company records transaction gains (losses) for fluctuations on foreign currency rates on accounts receivable, accounts payable, and cash as a component of other income (expense), net on the Consolidated Statements of Operations.

||||||||||||||||
| Income Tax, Policy [Policy Text Block] |
Income Taxes
The Company accounts for income taxes under the provisions of ASC topic 740, Income Taxes (“ASC 740”). ASC 740 requires an asset and liability based approach in accounting for income taxes. Deferred income tax assets, including net operating loss (“NOL”) and certain tax credit carryovers and liabilities, are recorded based on the differences between the financial statement and tax bases of assets and liabilities, applying enacted statutory tax rates in effect for the year in which the tax differences are expected to reverse. Valuation allowances are provided against deferred tax assets which are assessed as not likely to be realized. On a quarterly basis, management evaluates the recoverability of deferred tax assets and the need for a valuation allowance. This evaluation requires the use of estimates and assumptions and considers all positive and negative evidence and factors, such as the scheduled reversal of temporary differences, the mix of earnings in the jurisdictions in which the Company operates, and prudent and feasible tax planning strategies. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the dates of enactment. The Company accounts for unrecognized tax benefits based upon its assessment of whether a tax benefit is more likely than not to be sustained upon examination by tax authorities. The Company reports a liability for unrecognized tax benefits resulting from unrecognized tax benefits taken or expected to be taken in a tax return and recognizes interest and penalties, if any, related to its unrecognized tax benefits in income tax expense. See Note 3 for further discussion of the Company’s income taxes.

| New Accounting Pronouncements and Changes in Accounting Principles [Text Block] |
New Accounting Standards Adopted
In July 2012, the FASB issued ASU No. 2012-02, Intangibles-Goodwill and Other (topic 350): Testing Indefinite-Lived Intangible Assets for Impairment (“ASU 2012-02”). ASU 2012-02 provides entities with an option to first assess qualitative factors to determine whether events or circumstances indicate that it is more likely than not that the indefinite-lived intangible asset is impaired. If an entity concludes that it is more than 50% likely that an indefinite-lived intangible asset is not impaired, no further analysis is required. However, if an entity concludes otherwise, it would be required to determine the fair value of the indefinite-lived intangible asset to measure the amount of actual impairment, if any, as currently required under U.S. GAAP. ASU 2012-02 is effective for fiscal years beginning after September 15, 2012. The adoption of this pronouncement did not materially impact the Company’s financial condition or results of operations.
