Chipset is first device solution for EV-DO Rev B

Edited by the Electronicstalk editorial team Mar 27, 2007

The MSM7850 solution provides manufacturers with a highly integrated, flexible solution to deliver the capabilities of Rev B on consumer products.

Qualcomm has added a new product supporting CDMA2000 1xEV-DO Revision B to its roadmap.

The new Mobile Station Modem (MSM) MSM7850 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 datarates of 9.3Mbit/s on the downlink over 5MHz 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 (CSM) CSM6800 solution to support multicarrier 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 datarates of up to 73.5Mbit/s, while lower-cost or pre-existing devices could support 4.9Mbit/s.

Network operators may reduce their costs by allowing a greater%age of spectrum to be allocated to IP-based services.
