Qualcomm Announces EV-DO Rev. B Chipsets
Published on:
Qualcomm has unveiled the addition of a new product supporting CDMA2000 1xEV-DO Revision B to its roadmap. The new Mobile Station Modem MSM7850 chipset is the industry's first device solution for EV-DO Rev. B. 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.
A software upgrade release to enable Qualcomm's Cell Site Modem CSM6800 solution to support multi-carrier EV-DO Rev. B will be available by the end of March 2007.
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."
