CDMA2000 LEADS IN BRINGING ADVANCED SERVICES TO THE MARKET

CDMA2000 Will Continue to Evolve to Meet the Future Needs of Wireless Markets

COSTA MESA, Calif., May 2, 2005 – The CDMA Development Group (CDG) (www.cdg.org) announced today that the CDMA2000® industry is evaluating various enhancement techniques for next-generation CDMA2000 technologies. Building upon current industry leading capabilities, future enhancements will further increase spectral efficiencies and data throughput and will support the convergence of fixed, mobile and multicasting networks.

Perry LaForge , executive director of the CDG, commented, “3G CDMA technologies are rapidly transforming the wireless industry from voice-centric services to data-based services. The CDMA2000 industry has led this trend by commercializing new advanced technologies ahead of the market, thus offering operators significant competitive advantages. Next-generation CDMA2000 all IP-based standards are being developed and will deliver performance, flexibility and cost benefits that will take operators well into the future.”

The CDMA2000 evolution path offers competitive advantages to operators in high-speed data capabilities, cost of delivery and time to market. Through in-band migration, operators have been able to deploy CDMA2000 1X and 1xEV-DO Rev 0 and introduce enhanced voice services, broadband high-speed data and advanced multimedia services rapidly and cost-effectively. With data speeds of up to 2.4 Mbps in a single channel, 1xEV-DO Rev 0 is the fastest wireless data technology deployed today. The soon-to-be-deployed 1xEV-DO Rev A technology builds on Rev 0 capabilities and offers VoIP (voice over Internet Protocol) and significantly higher data rates (3.1 Mbps in the forward link and up to 1.8 Mbps in the reverse link in a single channel) allowing operators to further differentiate their service offerings, while reducing the cost of delivery.

The CDMA2000 standard also supports multiple carriers beyond a single 1.25 MHz channel (1X). In an evolved system using multiple carriers, operators can choose to deploy up to 15 carriers in a 20 MHz bandwidth, thereby achieving data rates of up to 46.5 Mbps.

At the upcoming “Evolving to Future Wireless Telecommunication Technology” workshop organized by 3GPP2, which will take place June 27-28 in Seoul, Korea, the CDMA2000 community will discuss various proposals for next-generation CDMA2000 technologies, including air interface technologies, speech coding, core networking, IP Multi-Media Subsystems, end-to-end quality of service management, security and OMA/Application Layer. The CDG and other industry experts will be presenting at this workshop. Within the CDG Evolution Team, carrier members are developing requirements which will be shared with the standards bodies.

About CDMA2000

CDMA2000 is by far the most widely deployed 3G technology, serving more than 147 million users worldwide. There are 127 CDMA2000 commercial networks, including 18 CDMA2000 1xEV-DO systems, and 40 more are being deployed. CDMA2000 has become the technology of choice for cdmaOne™, TDMA, analog and Greenfield operators, and is deployed in the 450, 800, 1700, 1900 and 2100 MHz bands. More than 720 CDMA2000 devices are available on the market.
