CDMA2000 EV-DO Revision B Standard to be published in 2006
The CDMA Development Group (CDG) has announced that the CDMA2000 EV-DO Revision B standard is on schedule to be published in the first quarter of 2006. Revision B is a further enhancement to the CDMA2000 standard, which introduces a 64-QAM modulation scheme, and will provide download speeds of 73.5 Mbps and uploads of 27 Mbps through the aggregation of 15 1.25 MHz carriers within 20 MHz of bandwidth. The higher speed will benefit 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. Revision B will preserve past investments as it is compatible with CDMA2000 1X, 1xEV-DO Release 0 and 1xEV-DO Revision A. The CDMA Development Group (CDG) expects that carriers will be able to launch Revision B in the year 2008.
