CSM solution for IMT-2000
WCDMA infrastructure and
test equipment
Standards based: FDD mode
3GPP, release 99 (ITU IMT-
2000 DS/UMTS)
2 Mbps data throughput:
provides significant
improvements over HSCSD,
GPRS and EDGE
Six sector support, with 12
uplink antenna inputs and 12
downlink antenna outputs
Support for three-way softer
hand-over (hand-off) to
support high quality,
interruption-free service
Support for transmit diversity,
including STTD and TSTD, for
improved mobile signal
reception
Support for 16 simultaneous
data or voice users, providing
higher density and lower
power requirements, enabling
support for more users at
lower cost in new, more
compact form factors
Simplified resource allocation,
supporting 16 uplink channel
resources and 32 downlink
channel resources; high-data-
rate channels require only a
single resource
Integrated ARM-7 processor
used for low-level physical-
layer tasks including
searching, finger assignment,
tracking and transport
channel steering functions
66 MHz PCI interface. Use of
this standard interface
simplifies device integration.
3.3 V I/O
1.8 V core
Device driver software that
runs on the host processor
and abstracts the low-level
hardware details from the
upper-layer applications
End-to-end tested with
MSM5200 solution
Enables high-bandwidth data
applications such as Internet,
multimedia and streaming
video
Provides increased capacity
and bandwidth for wireless
carriers over current 2G
standards
Relies on QUALCOMM’s
proven expertise and ability to
deploy IMT-2000 CDMA
technologies
