PCTEL and BridgePort Networks Demonstrate Seamless IMS Voice Call Handover Between GSM and Wi-Fi Networks at CTIA Wireless 2006

Business Wire, April 5, 2006

LAS VEGAS -- Companies Participating in Interoperable Implementation of 3GPP's IMS Voice Call Continuity Technical Requirements

PCTEL, Inc. (NASDAQ:PCTI), a leader in wireless broadband solutions, and BridgePort Networks, the leader in MobileVoIP convergence, today announced a joint demonstration of seamless IP Multimedia Subsystem (IMS) voice call handover between GSM and Wi-Fi Networks. The demonstration is taking place at the CTIA Wireless 2006 show in Las Vegas, Nevada (April 5-7).

The demonstration highlights the new voice call continuity capabilities of PCTEL's Roaming Client-VE (Voice Enabled) software and BridgePort Networks' NomadicONE IMS convergence server (ICS) product. The Roaming Client-VE software provides the same user experience and capabilities independent of handset platform and supports both Pocket PC 2003 and Windows Mobile 5.0.

With the PCTEL Roaming Client-VE, users can make and receive calls, on Wi-Fi or cellular networks, through a single user interface on their mobile device. Combined with Voice Call Continuity (VCC) capabilities, users can move from Wi-Fi to cellular coverage and vice-versa without dropping the call. The calls are seamlessly handed over based on the best network connectivity available to the device and/or user preference.

BridgePort Networks' NomadicONE ICS IMS-based fixed/mobile convergence solution provides mobile operators, fixed operators, cable operators and MVNOs the ability to offer single phone number voice services that can seamlessly hand over in-process voice calls between circuit-switched cellular and Voice over Wi-Fi access networks.

The respective solutions conform to technical requirements defined by the standards bodies 3GPP and 3GPP2 for IMS to circuit switched seamless voice handover, known as Voice Call Continuity (VCC). Specifically the solution demonstrated at the CTIA Wireless 2006 show implements the IMS Controlled Model (ICM) defined by 3GPP.

"We are very excited about our continued activities with Bridgeport in the seamless inter technology handoff of voice calls," said Biju Nair, vice president and general manager of PCTEL's Mobility Solutions Group. "Our joint focus is on standards based solutions in the IMS arena as well as interoperability with other industry solutions."

Attendees of the CTIA Wireless 2006 show are invited to visit PCTEL's booth # 4443 or BridgePort Networks' booth #3500.
