Qualcomm Announces Complete End-to-End CDMA2000 Revision D Commercial
Solution
May 22, 2003
Qualcomm announced the CSM6700 Cell Site Modem (CSM) solution and the
MSM6700 Mobile Station Modem (MSM) chipset and system software supporting
integrated voice and simultaneous high-speed packet data. The CSM6700
solution for infrastructure equipment will support 1xEV-DV including the
latest CDMA2000 Revisions C and D. The MSM6700 solution supports CDMA2000
through Revision D and 1xEV-DO.
The addition of the MSM6700 solution extends the number of standards
supported in the MSM6xxx chipset family, all based on radioOne Zero Intermediate
Frequency (ZIF) architecture, providing reduced bill of materials and
more cost-effective solutions for 3G wireless devices. The MSM6700 solution
supports CDMA2000 Revision D and CDMA2000 1xEV-DO and enables high-performance
applications processing for enhanced multimedia functionality, such as
video, graphics, camera, camcorder and gaming features in a single integrated
device.
The CSM6700 and MSM6700 solutions will be available to support CDMA2000
Revision D technology trials with samples expected to ship in 2004.
This new end-to-end solution allows for complete re-use of existing investments
in CDMA2000 1X and/or CDMA2000 1xEV-DO networks while providing a smooth
migration to Revision D, fully coordinated with CDMA2000 1xEV-DO.
CDMA2000 Revision D enables wireless carriers to provide voice and bi-directional
high-speed packet data services simultaneously on a single Radio Frequency
(RF) carrier. As specified by 3GPP2, the CDMA2000 Revision D standard
is backward compatible with IS-95 and the CDMA2000 Release 0, A, B and
C standards, providing today's CDMA2000 1X operators a seamless network
evolution. CDMA2000 Revision D is a significant advance over CDMA2000
Revision C supporting not only similar peak forward rates to 1xEV-DO but
also high data rate reverse links to better support high-resolution cameras,
video streaming, video telephony and other multimedia services. CDMA2000
Revision D and 1xEV-DO Revision A, also being developed in 3GPP2, will
allow the wireless operator two different complementary choices for deployment
of high rate forward and reverse link packet services.
The CSM6700 chip is targeted to deliver a higher level of integration
for CDMA2000 1X infrastructure equipment manufacturers for their CDMA2000
Revision D base station products, and is backward compatible with the
IS-95 and CDMA2000 1X Release 0 and Release A features. The CSM6700 solution
supports more than 200 forward-link and reverse-link channels and 4-way
receive diversity. Delivering more than six times the user capacity compared
to the current CSM5000 solution for CDMA2000 1X, the increased user capacity
allows infrastructure equipment manufacturers and network operators to
upgrade their CDMA2000 1X equipment with significantly higher network
capacity improvements, equipment design space savings and cost efficiencies.
