CDMA2000 1xEV-DO Revision A to Make Commercial Debut in 2006; Revision C Standard to be Published in 1H 2007

Las Vegas , NV — April 5, 2006 — The CDMA Development Group (CDG) ( today announced details about the CDMA2000® evolutionary roadmap, taking CDMA2000 into the next decade. Highlights include the commercial deployment of CDMA2000 1xEV-DO Revision A networks by late 2006, and the publication of the Revision C standard by the second quarter of 2007. These developments put CDMA2000 operators ahead in the introduction of all-IP and next-generation multimedia technologies.

“With commercial Revision A products available this year, and work on Revision C well underway, CDMA2000 has a clear evolutionary path for the next decade,” said Perry LaForge, executive director of the CDG. “This roadmap gives CDMA2000 operators and equipment manufacturers a major competitive advantage in terms of time-to-market because they can make and execute long-range plans today.”

CDMA2000 evolution will include the following milestones:

  • CDMA2000 1xEV-DO Revision A – The commercial availability and first deployments of CDMA2000 1xEV-DO Revision A in Asia and North America will start at the end of 2006, with wide deployment in 2007. Revision A leverages CDMA’s IP heritage and introduces enhancements that support latency-sensitive and bandwidth-intensive applications such as Voice over IP (VoIP) and Instant Multimedia Messaging (IMM), and it allows operators to provide integrated voice, data and video services at a lower cost and across multiple networks. KDDI, LG Telecom, Sprint Nextel, Telecom New Zealand and Verizon Wireless are among the operators that have committed to or have begun deploying Revision A.
  • CDMA2000 1xEV-DO Revision B – Approved for publishing by 3GPP2 TSG-C in March 2006, the Revision B standard increases throughput to 73.5 Mbps on the downlink and 27 Mbps on the uplink via multiple carriers and a 64-Quadrature Amplitude Modulation scheme.
  • CDMA2000 1xEV-DO Revision C – This advanced interface will deliver higher data rates and spectral efficiency along with low latency, making it ideal for enriched multimedia services. Revision C will support flexible and dynamic channel bandwidth scalability from 1.25 MHz up to 20 MHz and will be backward-compatible with Revisions A and B. Currently, 3GPP2 is evaluating various proposals, which include OFDM, MIMO, SDMA and Interference Cancellation techniques, with the harmonization of the proposals to be completed by June of this year. Revision C will not only increase the peak rates up to 200 Mbps in the downlink but will also provide significant gain in sector throughput, which is essential for cost-effectively supporting several broadband users simultaneously. The standard is expected to be published by Q2 2007 with commercial products in the second half of 2008.

“CDMA2000 has a 2-3 year lead in 3G and wireless broadband today,” continued LaForge. “And with a clear vision and a proven track record of timely delivery, the CDMA2000 industry will also set the pace in the evolution to next-generation services.”

“Lucent is committed to ensuring that CDMA2000 remains a cost-effective technology that provides mobile operators with the most advanced features and an easy migration path to future network enhancements,” said Mike Iandolo, president of Mobility Access Solutions for Lucent Technologies’ Network Solutions Group. “Working with other members of 3GPP2, we’ve developed an attractive evolution path for CDMA operators that will enable them to deliver the most innovative wireless services for years to come.”

"Motorola is actively involved in the evolution of the CDMA air interface, and we believe the benefits to our operator customers will be tremendous both in the services and applications they can offer their end-users," said Bruce Stone, Motorola senior vice president of CDMA Cellular Networks.

“1xEV-DO Revision C incorporates the advancements in OFDM and MIMO technologies that are fundamentally going to be a common building block for all the next-generation wireless access technologies," said Doug Wolff, general manager, CDMA, Nortel. "While laying a competitive evolution path for operators, 1xEV-DO Revision C will change the way subscribers use broadband wireless by delivering significant increase in throughputs and peak rates.”

“The CDMA2000 evolution path has no end in sight and continues to provide operators with a time-to-market advantage in providing consumers and enterprise users with a compelling array of applications and services, including rich multimedia content and mobile broadband,” said Jeffrey A. Jacobs, president, Global Development, QUALCOMM®.

A number of manufacturers are featuring CDMA2000 next generation capabilities at CTIA Wireless 2006 in Las Vegas this week.
