Qualcomm teams with vendors to develop CDMA2000 1xEV-DO Revision A

November 15, 2004

Qualcomm announced that major infrastructure vendors, including Airvana, Ericsson, Hitachi, Lucent, Motorola, Nortel Networks and Samsung, have selected Qualcomm's Cell Site Modem (CSM) CSM6800 digital baseband modem for infrastructure and test equipment to drive adoption of CDMA2000 1xEV-DO Revision A. Qualcomm's Technology Development Program - based on the CSM6800 device - is to drive the next generation of wireless data solutions based on the global deployment of 1xEV-DO Rev. A. Qualcomm's technology program enables accelerated development of equipment system software and hardware in preparation for planned technology trials and commercialization of worldwide 1xEV-DO Rev. A technology solutions.

"Working with the world's leading infrastructure vendors, Qualcomm's technology program will significantly impact the global availability of CDMA2000 1xEV-DO Rev. A," said Dr. Sanjay K. Jha, president of Qualcomm CDMA Technologies. "With the acceptance of 1xEV-DO - both Rev. 0 and now Rev. A - Qualcomm continues its leadership in CDMA technologies, supporting major OEMs and operators worldwide with complete system solutions."

CDMA2000 1xEV-DO Rev. A enables rich wireless multimedia services such as high-speed upload of multimedia files and attachments, interactive gaming and a variety of IP-based services such as Voice over Internet Protocol (VoIP). Rev. A will also support real-time conversational services such as push to talk, video telephony and instant multimedia - an extension of push to talk that combines immediate voice with simultaneous delivery of video and pictures. Support for multimedia multicasting services is enabled by Qualcomm's recently announced 1xEV-DO Platinum Multicast enhancement. Platinum Multicast enables network operators to provide multimedia services that deliver high-quality video and audio to a large number of users simultaneously.

With support for peak data rates of 3.1 Mbps on the forward link and 1.8 Mbps on the reverse link, Rev. A enables network operators to provide an even broader range of wireless multimedia and other data services for consumers and enterprise customers. Rev. A is optimized for packet data service and provides one of the lowest costs per bit when compared with other wireless wide area network (WAN) technologies.

Qualcomm's CSM6800 single-chip solution delivers a significant chip count reduction to infrastructure equipment manufacturers for their CDMA2000 1xEV-DO Rev. A base station products. The CSM6800 solution is backward compatible with 1xEV-DO Rev. 0 and provides 192 forward-link and reverse-link channels, supporting eight times the number of channels compared to the current CSM5500 solution for 1xEV-DO Rev. 0. The increased user capacity allows infrastructure equipment manufacturers and network operators to cost-effectively upgrade their existing 1xEV-DO equipment and save equipment space.
