CDMA2000 1xEV-DO Revision B plans on target

Qualcomm has confirmed that the high-speed wireless CDMA2000 1xEV-DO Revision B specification is still on schedule for commercialisation in 2007.

The technology promises support for higher wireless data rates that can act as a springboard for delivering next-generation wireless data, music, gaming and multimedia entertainment.

Qualcomm's Mobile Station Modem offerings for EV-DO B will support the operation of up to three simultaneous channels of 1.25MHz each for faster data rates, and up to 4.9Mbps in each channel for a combined three-channel data speed of up to 14.7Mbps on the downlink.

EV-DO B technology is part of the company's DO Multicarrier Multilink eXtensions platform, enabling applications such as mobile TV or streaming music with a concurrent voice call, or conducting a VoIP conversation while browsing the internet or transmitting multimedia content over the network.

Extremely high-performance devices could support forward-link data rates of up to 73.5Mbps, while lower-cost or pre-existing devices could support 4.9Mbps, Qualcomm said.

Network operators could reduce their costs by allowing a greater percentage of spectrum to be allocated to IP-based services.

"Consumers want devices that are smaller, lighter, faster, cheaper, fully featured and with longer battery life," said Sanjay Jha, president of Qualcomm CDMA Technologies.
