PCTEL's Segue™ Roaming Client Boosts Wi -Fi Security with 802.1x and "Wi -Fi Protected Access"

WPA and 802.1x Improve Security for Enterprises and SOHO Users

CHICAGO / MUNICH, September 29, 2003 - - PCTEL, Inc. (Nasdaq: PCTI), a leading provider of wireless solutions and access technology, today announced the immediate availability of its Segue™ Roaming Client software with full support for 802.1x secure authentication and the Wi -Fi Protected Access (WPA) encryption standard. PCTEL will demonstrate its secure version of the Segue™ Roaming Client at the Wi -Fi Planet conference and exposition in Munich, Germany (September 29 - 30).

The Segue™ Roaming Client provides mobile users secure, seamless access and roaming capabilities for Wi -Fi networks and cellular data networks in public areas, at the office, and in the home. The Roaming Client enables rapid scanning of available networks and a user -friendly connection process.

WPA is a new, Wi -Fi Alliance mandated security mechanism that eliminates security holes in previous encryption efforts. WPA also protects users and networks from malicious attacks. The 802.1x standard is a framework for secure, mutual authentication between a network and end -users that prevents unsuspecting parties from transmitting information between each other. Many enterprises currently support 802.1x to protect their wireless networks.

"Security and ease -of -use continue to represent barriers to the inevitable Wi -Fi explosion," said Marty Singer, PCTEL's Chairman and CEO. "The combination of the Segue™ Roaming Client's user interface and facilities with the WPA and 802.1x security enhancements will accelerate business use of Wi -Fi networks," added Singer.

PCTEL's secure version of the Segue™ Roaming Client is now available via its website at www.pctel.com and as a customized offering to equipment providers, carriers, and other service providers. The Segue™ Roaming Client supports both WPA and non -WPA modes of operation and can be effective in migrating users to WPA in mixed use environments. The Segue™ Roaming Client can also leverage the backend administrative capabilities of the Segue™ Central Configuration Server (CCS) to allow detailed control and update of users' wireless configuration from a central location.

The Segue™ Roaming Client is compatible with Microsoft Windows® 2000, and Microsoft Windows XP. Future versions will provide support for Mircosoft Windows 98 (Second Edition) and Microsoft Windows ME. In addition, more than 80 Wi -Fi adapters are certified for compatibility with the Roaming Client software.
