PCTEL Seeks To Enhance Wi-Fi and DSL Integration by Acquiring Important DSL Patents from ITeX

CHICAGO--May 21, 2003--PCTEL, Inc. (Nasdaq: PCTI), a leading provider of Internet access technology, 802.11 mobility software, and software-defined radio products, announced today that it had acquired four U.S. patents related to DSL modem technology as part of bankruptcy proceedings surrounding Integrated Telecom Express, Inc. (ITeX). The purchase includes all continuations and foreign counterparts. The terms of the purchase agreement were not disclosed. The patents cover ADSL (Asymmetrical Digital Subscriber Line) modem technology. The patents describe techniques for permitting an operating system to utilize, configure and control an ADSL software modem. They deal with, among other issues, latency, flexibility and ADSL links that vary depending on processing resources. "We will continue to build our patent portfolio, focusing on access technology," said Marty Singer, PCTEL Chairman and CEO. "The company now has critical mass in ADSL patents to offer meaningful technology licenses to companies shipping ADSL products. Our goal is to effectively license our technology, building upon the patent portfolio that we developed and the substantial portfolio that we acquired from Conexant." PCTEL recently divested its HSP modem product line. The company received cash, royalties, and a patent portfolio from Conexant in a recently completed transaction. PCTEL generated nearly $8 million in licensing and royalty revenues over the past five quarters and plans to develop this business as it expands its Wi-Fi and software-defined radio programs. ITeX was a leading innovator and provider of ADSL chipsets, network software and development tools. A leader in broadband technology development, ITeX had more than 50 patents granted or filed worldwide. ITeX shipped more than one million ADSL chipsets before the company filed for bankruptcy protection during the recent economic downturn. ITeX's Official Committee of Equity Security Holders engaged CERIAN Technology Ventures, LLC as intellectual property advisors, to assist the committee in maximizing the value of the estate's distressed technology assets. CERIAN worked with ITeX management, the Committee and PCTEL to bring the transaction to fruition.

The patents covered in this purchase are (US Patent numbers):

-- 6,400,759 -- Device driver for rate adaptable modem with forward compatible and expandable functionality

-- 6,233,250 -- System and method for reducing latency in software modem for high-speed synchronous transmission
