Exhibit 99.1

PCTEL Posts $15.6 Million in First Quarter Revenue

Bloomingdale, IL April 22, 2010 — PCTEL, Inc. (NASDAQ: PCTI), a leader in propagation and wireless network optimization solutions, announced results for the first quarter ended March 31, 2010.

First Quarter Financial Highlights

• $15.6 million in revenue for the quarter, an increase of 10% over the same period in 2009.

• GAAP Gross Profit Margin from continuing operations of 46 percent, as compared to 47% for the same period last year.

• GAAP Operating Margin of a negative (9) percent as compared to a negative (19) percent in the same period in 2009. The operating results for the first quarter 2009 included a $1.5 million impairment of goodwill related to the acquisition of Wi-Sys Communications. Without the impairment charge the GAAP operating margin for the first quarter of 2009 would have been negative (8) percent.

• Non-GAAP Operating Margin of two percent versus three percent in the same period in 2009. The Company’s reporting of non-GAAP operating margin excludes expenses for restructuring, gain or loss on sale of assets, stock based compensation, amortization and impairment of intangible assets and goodwill related to the Company’s acquisitions.

• GAAP net loss of $(795,000) for the quarter, or $(0.05) per share, compared to a net loss of $(1.9) million, or $(0.11) per diluted share for the same period in 2009. The $1.1 million difference is primarily attributed to the first quarter 2009 impairment of goodwill net of tax.

• Non-GAAP net income of $356,000 for the quarter, or $0.02 per diluted share compared to $451,000 of net income, or $0.03 per diluted share, for the same period in 2009. The Company’s reporting of non-GAAP net income excludes expenses for restructuring, gain or loss on sale of assets, stock based compensation, amortization and impairment of intangible assets and goodwill related to the Company’s acquisitions, and non-cash related income tax expense.

• $72.5 million of cash, short-term investments, and long-term investments at March 31, 2010, a decrease of $(3.1) million from the quarter ended December 31, 2009. During the first quarter the

company paid out cash of $2.4 million for the Sparco Technologies acquisition. The company used approximately $700,000 in cash and investments from all other sources during the quarter.

“Our results suggest that we are continuing to make progress and that there is a renewed investment in both public and private networks,” said Marty Singer, PCTEL’s Chairman and CEO. “We believe that our acquisitions were well-timed and that our product line expansion will accelerate our growth as the economy recovers,” added Singer.

This schedule reconciles the company’s GAAP operating income and GAAP net income from to its non-GAAP operating income The company believes that presentation of this schedule provides meaningful supplemental information to both management and investors that is indicative of the company’s core operating results and facilitates comparison of operating results across reporting periods. The company uses these non-GAAP measures when evaluating its financial results as well as for internal planning and forecasting purposes. These non-GAAP measures should not be viewed as a substitute for the company’s GAAP results.
