QUALCOMM said its upcoming CDMA2000 1xEV-DO Revision B chipset is on schedule for commercial release in 2007.
QUALCOMM’s Mobile Station Modem (MSM) solutions for EV-DO Rev. B will be highly integrated with advanced functionality, support the operation of up to three simultaneous channels of 1.25 MHz each for higher-speed data rates and deliver significant space-savings for devices that are thinner, smaller and lighter.
The EV-DO Rev. B standard supports up to 4.9 Mbps in each channel for a combined three-channel data speed of up to 14.7 Mbps on the downlink.
QUALCOMM expects the first commercial EV-DO Rev. B products to be data modems available in late 2007, with additional wireless devices available soon thereafter.
EV-DO Rev. B. technology is part of the Company’s DO Multicarrier Multilink eXtensions (DMMX) platform, a set of technology and product innovations announced in November 2005.
Extremely 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. The DMMX platform also includes numerous QUALCOMM-developed techniques to further enhance the voice and data performance of EV-DO networks.
“Consumers want devices that are smaller, lighter, faster, cheaper, as well as fully featured and with longer battery life,” said Dr. Sanjay K. Jha, president of QUALCOMM CDMA Technologies. “We are committed to enabling our customers to meet these market demands, rapidly moving forward in the evolution of CDMA2000 technology to bring unprecedented levels of data throughput and network capacity with EV-DO Rev. B – capabilities that are necessary to support tomorrow’s high-performance wireless applications.”http://www.qualcomm.com
- In October 2005, QUALCOMM reached a milestone in the development of CDMA2000 1xEV-DO Revision A networks and handsets — the completion of an end-to-end call.
The Rev. A standard represents the next evolution of the EV-DO technologies that support the 3.1 Mbps forward and 1.8 Mbps reverse link data rates and higher system capacity required for next-generation wireless multimedia.
