No Need To Wait For 3G Or Expensive Networks

The Segue™ Roaming Client Will Enhance Interoperability and Roaming between 802.11 and CDMA2000 1X and GPRS Networks

PCTEL announced the launch of its Dual-Mode Segue™ Roaming Client software at the EyeforWireless Conference and Exhibition at the Sheraton Gateway hotel in San Francisco, February 27-28, 2003. The Segue™ Roaming Client represents PCTEL's commitment to resolve the problems that service providers and subscribers encounter when roaming wide-area cellular data service (CDMA2000 1X and GPRS) to wireless local area networks (WLAN, or "Wi-Fi").

"Wi-Fi is proving an enormous boon to mobile data services and our Segue™ Roaming Client will help them leverage their existing subscriber base, billing systems and experience in addressing roaming problems to offer a compelling wireless data service to people on the move," said Marty Singer, PCTEL Chairman and CEO. "In effect, cellular carriers do not have to wait for 3G - or build expensive 3G networks - to realize significantly increased revenues from mobile data services."

PCTEL will also provide a Wi-Fi network and demonstration copies of its Segue™ Roaming Client for EyeforWireless conference participants.

The Dual-Mode product builds upon PCTEL's existing Segue™ Roaming Client software. The previous release of the Roaming Client automatically configures laptops so that they can operate in different 802.11 environments, enabling mobile data subscribers to roam from one WLAN to another WLAN.

The Segue™ Roaming Client offers the following benefits:

-- Provides customers with a simple mechanism to locate available Wi-Fi "hotspots," using PCTEL's "Location Finder" feature.

-- Maintains customer "stickiness." A carrier's customer will remain on the same network or the network of a roaming partner. Without this feature, a customer's laptop could default to another network. This simplifies billing for carriers and customers.

-- Enhances security by providing automatic detection, selection, and connection to networks in a pre-determined manner.

By addressing the access, billing, convenience and quality of service issues listed above, the PCTEL Segue™ Roaming Client eliminates the barriers service providers face when deploying Wi-Fi networks to augment their wide-area cellular data services.
