KYOCERA Wireless Corp. and Togabi Announce Development and Licensing Agreement for Push-To-Talk Functionality

Kyocera to Incorporate Standards-based PacketCHAT Client Technology into Innovative Line of Wireless Handsets

SAN DIEGO -- (October 21, 2003) -- Kyocera Wireless Corp., a leading global CDMA wireless handset manufacturer, and Togabi Technologies, a leading wireless software infrastructure provider specializing in real-time wireless communications, announced today a development agreement to outfit selected future wireless handsets from Kyocera Wireless with Togabi’s advanced push-to-talk (PTT) and real-time wireless media functionality.

Togabi’s PacketCHAT is an advanced end-to-end communications solution that enables instant one-to-one and one-to-many, half-duplex PTT calls over packet networks. Integrated into both mass-market phones and carrier-grade application servers in the wireless operator’s network, PacketCHAT is based on today’s industry standard IP technologies such as Real Time Protocol (RTP) and Session Initiation Protocol (SIP). PacketCHAT supports CDMA/1xRTT, GSM/GPRS wireless networks, 802.11 a/b networks, 3G (e.g. CDMA 2000, UMTS), as well as wireline networks. Togabi’s end-to-end solution leverages the strengths of its worldwide handset and infrastructure partnerships to offer a high-performance, interoperable instant communications platform for enterprise and consumer segments.

Kyocera Wireless Corp. markets its popular line of CDMA wireless handsets throughout the Americas, as well as India, Australia and New Zealand. Kyocera Wireless plans to have Togabi-enabled PTT handsets available for distribution by wireless carriers in the first half of 2004.

“PTT is clearly being embraced by a growing number of CDMA carriers and Kyocera Wireless is committed to working with technology leaders like Togabi to provide those carriers with PTT-enabled handsets that will be compelling to their customers,” said Tsuyoshi Mano, president of Kyocera Wireless Corp. “All of our phones are designed to simplify the lives of their users, and we believe many of those users will use PTT to stay better connected.”

Togabi has multiple PTT trials ongoing on all major network technologies across four different continents and with three of its worldwide distribution partners. Togabi’s strategy is to continue building its increasing-diverse portfolio of high-volume client devices and carrier-grade server platforms to support PTT opportunities worldwide.

“This Agreement further extends PacketCHAT’s reach onto three continents and into Kyocera Wireless’ innovative product portfolio that incorporates an entirely new level of push-to-talk capabilities,” notes Mark Handzel, president and CEO for Togabi Technologies. “Our industry-leading, standards-adhering wireless client was expressly built for high-quality, high-volume handsets -- a major competitive asset for both companies’ offerings.”
