CDMA2000 EV-DO Revision B Standard to be Published in First Quarter of 2006
Posted on 17-Nov-2005 09:11 | Tags Filed under: News



The CDMA Development Group (CDG) says the standard for CDMA2000 EV-DO Revision B is on schedule to be published in the first quarter of 2006, under document number 3GPP2 C.S0024-B and by the Telecommunications Industry Association (TIA) and Electronics Industry Association as TIA/EIA/IS-856-B.

Revision B is a further enhancement to the CDMA2000 standard and 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.

According to the group, the CDMA2000 EV-DO standards, which are 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).

The current CDMA 1xEV-DO Release 0 offers peak data rates of 2.4 Mbps. In early 2006, CDMA2000 operators will migrate to 1xEV-DO Rev. A, which will offer higher peak data rates, up to 3.1 Mbps on the forward link and 1.8 Mbps on the reverse link, and lower system latencies to support delay-sensitive applications.

With Rev. A, operators will be able to introduce advanced multimedia services, including voice, data and broadcast over all-IP networks. The evolution to EV-DO Rev. B (also known as DO Multicarrier) will follow beginning in 2008, and will allow operators to quickly transition to enhanced next-generation interactive services using existing frequency bands and/or new spectrum allocations.

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.

The group says this strategy will be complemented with efforts to expand the CDMA2000 market by improving global roaming and reducing the cost of handsets to below US$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.
