Chicago, IL - October 28, 2003 - PCTEL, Inc. (Nasdaq: PCTI), a leading provider of wireless solutions and access technology, today announced that its Segue™ Roaming Client software was adopted by NTT DoCoMo, Inc. to improve its Wi -Fi access service, named Mzone™, in Japan. PCTEL will add several features to Mzone to enhance its usability.

In this deployment, the Segue™ Roaming Client will feature full Kanji capabilities, a Wi -Fi service area database for Japan and the capability of automatically switching between NTT DoCoMo's Wi -Fi access service and other roaming or customer -registered Wi -Fi networks. The Segue™ Roaming Client will also provide secure connections for Mzone users by incorporating the IEEE 802.1X (TTLS) authentication mechanism and supports most major Wi -Fi cards distributed in Japan. All Mzone subscribers in Japan will be able to download the Segue™ Roaming Client customized for Mzone from NTT DoCoMo's Japanese website for its Wi -Fi customers.

"We are honored that NTT DoCoMo has chosen to work with us in this important and strategic service area," said Marty Singer, Chairman and CEO of PCTEL. "This development has tremendous implications for PCTEL in Asia, given the proportionately large numbers of mobile data users in that region."

In a future release of the Segue™ Roaming Client, PCTEL will incorporate a roaming capability with wide area networks such as PHS and W -CDMA in addition to Wi -Fi networks.
