COSTA MESA, Calif., April 12, 2004 – The CDMA Development Group (CDG) (www.cdg.org) reported today that CDMA2000® 1xEV-DO Revision A has been approved by the 3GPP2 Technical Specification Group (TSG-C). Revision A is optimized for packet data service, and supports peak data rates of 3.1 Mbps on the forward link and up to 1.8 Mbps on the reverse link. The high data rates on the reverse link and low data latency will enable operators to deliver rich multimedia services, such as video telephony, and will enhance user experience.

“CDMA2000 technology continues to evolve to provide unparalleled speed and efficiency,” said Perry LaForge, executive director of the CDG. “With CDMA2000 1xEV-DO Revision A, carriers will be able to further differentiate their services through a broad range of new, innovative wireless data offerings. Today’s announcement is yet another milestone for CDMA2000 and we are extremely pleased with the progress 3GPP2 and the CDMA industry is making in delivering advanced technologies to meet the evolving needs of wireless communications.”

CDMA2000 1xEV-DO Release A is an enhanced version of CDMA2000 1xEV-DO Release 0, which delivers up to 2.4 Mbps data speeds and has been commercially deployed since 2002. There are nine CDMA2000 1xEV-DO commercial networks in Asia, North America and Latin America today, with four more scheduled to be deployed in 2004. CDMA2000 1xEV-DO already delivers the highest data rates in commercial networks (average data rates of 300-600 kbps) and supports advanced data applications such as MP3 transfers and video conferencing, TV broadcasts, video and audio downloads.

Demand for advanced CDMA2000 1xEV-DO services is growing rapidly; the number of users reached 4.38 million at the end of 2003. In Korea, SK Telecom’s CDMA2000 1xEV-DO base represents 25 percent of its CDMA2000 users after less than two years of service. In January, Verizon Wireless announced the nationwide expansion of its CDMA2000 1xEV-DO network after the successful introduction of its CDMA2000 1xEV-DO services in the San Diego and Washington, D.C. metropolitan areas in October last year.

CDMA2000 subscriber statistics and deployment information are available on the CDG Web site at www.cdg.org.
