CDMA2000 EV-DO REVISION B STANDARD TO BE PUBLISHED IN FIRST QUARTER OF 2006
Evolution to EV-DO Revision B Further Enhances the CDMA2000 Roadmap while Preserving Existing Investments
HONG KONG , November 16, 2005 – The CDMA Development Group (CDG) (www.cdg.org) today announced that the standard for CDMA2000 EV-DO Revision B is on schedule to be published in the first quarter of 2006. Revision B is a further enhancement to the CDMA2000 standard and significantly increases the data throughput up to 73.5 Mbps in the forward link and 27 Mbps in the reverse link by dynamically allocating multiple radio frequency (RF) carriers across wider frequency blocks.
In addition to supporting mobile broadband data and OFDM-based multicasting, the lower latency characteristics of Revision B will improve the performance of delay-sensitive applications such as voice over Internet protocol (VoIP), push-to-talk over cellular, video telephony, concurrent voice and multimedia and massive multiplayer online gaming. Since many IP-based applications are real-time in nature, the standard will also support interactive voice communications simultaneously with data sessions and extend the battery life of mobile devices. Revision B will preserve past investments by being compatible with CDMA2000 1X, 1xEV-DO Release 0 and 1xEV-DO Revision A.
“EV-DO Rev. B will mark another breakthrough in mobile communications and will enable operators to retain their first-to-market advantage in advanced capabilities, while increasing their system capacity and lowering cost of delivery,” said Perry LaForge, executive director of the CDG. “CDMA operators will be well-positioned to succeed in highly competitive markets today and in the future.”
CDMA2000 EV-DO standards, optimized for data, have introduced a number of enhancements to the 3G technologies, such as increased system capacity, lower cost per bit, lower latency, enhanced QoS, simultaneous voice and data services, longer battery life and connectivity to the All-IP Multimedia Domain (MMD). EV-DO has been commercial since 2002, and since then operators in developed and developing markets alike have seen the usage and revenue from broadband data services rise rapidly. This adoption is accelerated by the increasing availability and rapidly declining prices of 1xEV-DO devices; there are more than 150 devices, including phones, PC cards and fixed terminals manufactured by 18 vendors today.
Regarding future strategies, CDMA2000 operators will continue to upgrade their network capabilities and refine business models to deliver seamless access to a broad range of integrated voice, video and data services. The core of this strategy will be to enhance EV-DO beyond Rev. B, to include the seamless integration of other wireless access technologies, smart antennas and all-IP-based core networks. This strategy will be complemented with efforts to expand the CDMA2000 market by improving global roaming and reducing the cost of handsets to well below $40 through economies of scale and industry initiatives, such as Global Handset Requirements for CDMA (GHRC) and a streamlined test and certification process for CDMA devices.
Revision B introduces a 64-QAM modulation scheme, and will deliver peak rates of 73.5 Mbps in the forward link and 27 Mbps in the reverse link through the aggregation of 15 1.25 MHz carriers within 20 MHz of bandwidth. A single 1.25 MHz carrier and an aggregated 5 MHz carrier in the forward link will deliver peak rates of up to 4.9 Mbps and 14.7 Mbps, respectively.
