US : QUALCOMM Incorporated unveiled the addition of a new product supporting CDMA2000(R) 1xEV-DO Revision B to its roadmap. The new Mobile Station Modem(TM) (MSM(TM)) MSM7850(TM) chipset is the industry's first device solution for EV-DO Rev. B, delivering highly advanced capabilities for next-generation data and multimedia services. QUALCOMM's recent field tests of EV-DO Rev. B technology resulted in average data rates of 9.3 Mbps on the downlink over 5 MHz of spectrum.
"The evolution of CDMA2000 networks from EV-DO Rev. A to EV-DO Rev. B allows network operators to remain leading-edge in their service and performance offerings without the need for any infrastructure hardware changes," said Dr. Sanjay K. Jha, chief operating officer of QUALCOMM and president of QUALCOMM CDMA Technologies. "QUALCOMM's technology will allow 3G CDMA networks to meet next-generation data requirements." The MSM7850 device chipset provides support for EV-DO Rev. B with full backward compatibility. Scheduled to sample this year, the MSM7850 solution provides manufacturers with a highly integrated, flexible solution to deliver the capabilities of Rev. B on consumer products. A software upgrade release to enable QUALCOMM's Cell Site Modem(TM) (CSM(TM)) CSM6800(TM) solution to support multi-carrier EV-DO Rev. B will be available by the end of March 2007.
EV-DO Rev. B. enables applications such as mobile TV or streaming music with a concurrent voice call, or conducting a Voice over Internet Protocol (VoIP) conversation while simultaneously browsing the Internet or transmitting multimedia content over the network. The flexibility of EV-DO Rev. B technology also enables significant network capacity and performance enhancements while leveraging existing network investments and currently deployed devices. High-performance devices could support forward-link data rates of up to 73.5 Mbps, while lower-cost or pre-existing devices could support 4.9 Mbps. Network operators may reduce their costs by allowing a greater percentage of spectrum to be allocated to IP-based services.
