Prototype Handset is Proof of Concept to Address Growing Demand for Dual-Mode Voice Call Continuity

Kyocera Wireless Corp., a leading global supplier of CDMA wireless devices and accessories, and PCTEL Inc., a leader in wireless broadband solutions, announced today their collaboration on a Voice Call Continuity (VCC) solution for dual-mode Wi-Fi/CDMA handsets. The solution, which incorporates PCTEL's Roaming Client - Voice Enabled (VE), is being demonstrated on a prototype Kyocera handset. VCC technology allows a dual-mode handset to make seamless handoffs of active calls while moving between Wi-Fi and CDMA air interfaces.

"Adding Voice Call Continuity to our portfolio represents the latest step by Kyocera Wireless in creating a commercial handset that brings together the best of CDMA and Wi-Fi without sacrificing any functionality," said Dave Carey, vice president of strategic planning for Kyocera Wireless Corp. "This Kyocera/PCTEL collaboration demonstrates our commitment to developing innovative wireless devices that leverage expanding wireless technology as they improve today's busy lifestyles."

According to analyst firm ABI Research, as soon as 2008 more than 11 million subscribers will be using VCC solutions for dual-mode Wi-Fi mobile phones. The new VCC solution integrates Kyocera's CDMA voice, user interface and Short Message Service (SMS) features with PCTEL's Voice Over IP (VoIP), SMS Over IP, single-number roaming and active-call handover functionality.

"Dual-mode phones with roaming and call hand-over capabilities deliver powerful advantages to consumer and enterprise markets," said Biju Nair, vice president and general manager of PCTEL's Mobility Solutions Group. "Our effort with Kyocera demonstrates a market-ready IMS voice application on a mass-market dual-mode handset."

PCTEL will demonstrate the Roaming Client - VE on the Kyocera Wireless mobile handset at its booth (#3767) at CTIA 2007 in Orlando the week of March 26, 2007.
