Motorola Takes Leadership Role in 3GPP2 Adoption Of 1xEV-DV Baseline Framework

date: October 31, 2001

Motorola's Global Telecom Solutions Sector (GTSS) took a leadership role in the adoption of 1xEV-DV, the baseline framework for the evolution of 3G Code Division Multiple Access (CDMA) 2000 1X wireless services.

A consensus was reached on the baseline framework for CDMA2000 1xEV-DV (data and voice) by the standards body on Oct. 18 during meetings in Korea. The 1xEV-DV standard is scheduled 3G Partnership Project 2 (3GPP2) publication in March 2002 and International Telecommunications Union (ITU) 3G approval in May 2002.

This next evolution technology is designed to provide integrated voice with simultaneous high-speed packet data, video and video conferencing capabilities. 1xEV-DV will be backward compatible with IS-95A/B and CDMA2000 1x, allowing for a graceful operator evolution of their currently deployed systems.

"We are pleased and very excited that we can move forward with CDMA2000 1xEV-DV technology solutions," said Keith Ten Brook, senior director of advanced technology for Motorola's GTSS. "Motorola continued its leadership role in this standardization process by soliciting the support of operators, network vendors and suppliers for the adoption of a baseline framework that combines elements of the two leading proposals before the standards body. Our main goal was to move this standard along in order to develop products that will deliver the simultaneous voice and high-speed data services that CDMA network operators have indicated they want," said Ten Brook.

Motorola has led the way toward developing a 1xEV-DV solution for CDMA2000. In March 2000, an initial CDMA2000 1xEV-DV proposal was submitted to 3GPP2. Many of the concepts from that Motorola-backed proposal have been included in the current 1xEV-DV proposal to improve the performance, including: four-channel hybrid ARQ (automatic request for retransmission), concatenation of multiple Walsh codes, adaptive modulation and coding, and fast cell selection.

Motorola is the only network vendor in the world to successfully demonstrate technology elements of a CDMA2000 1xEV-DV solution. Ten Brook said that if the standard is finalized in May 2002, 1xEV-DV services could be commercially available in the first half of 2004.

M-Profits: Making Money from 3G Services
ISBN: 0470847751

This book discusses 3G services from the view of what is needed for the service to provide value to the user, what is the value proposition for the user, how will money be made out of delivering the service, and discussions on how revenue sharing propositions might work to benefit content providers and network operators. 3G operators should take note of this highly recommended book.
