Qualcomm Inc. introduced a modem chipset for its EV-DO Rev. B that is capable of delivering average data rates of 9.3Mbps on the downlink over 5MHz of spectrum.

The Qualcomm Mobile Station Modem MSM7850 chipset is the first device announced for the high-speed wireless technology, the firm said, noting that the speeds will open the way for mobile TV and streaming music with simultaneous voice calling. Users of the mobile phone technology will be able also to make VoIP calls while browsing the Internet or transmitting multimedia.

"The evolution of CDMA 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 Sanjay K. Jha, chief operating officer of Qualcomm and president of Qualcomm CDMA Technologies. In the United States, Verizon Wireless, Sprint and Alltel have been deploying Qualcomm's Rev. A.

Scheduled to sample later this year, the MSM7850 is backward compatible with earlier EV-DO technologies. Qualcomm said software upgrades for the company's earlier Cell Site Modem CSM6800 for support of the Rev. B version will be available this week.

In another development, Qualcomm unveiled single chip Rev. A systems including the QSC6085 that is being adopted by wireless service provider China Unicom and handset manufacturer Sanyo.

Qualcomm said the QSC6085 is pin-and software-compatible with its previous QSC families, allowing device makers to utilize their existing hardware platforms and software applications. The company added that the QSC family is being used by device manufacturers and service providers in India by Tata Teleservices and in China by Huawei Mobile and ZTE.
