MSM6250™ CHIPSET SOLUTION
Combine these features with QCT's radioOne™ Zero Intermediate
Frequency (ZIF) direct conversion architecture - which eliminates
the need for large IF Surface Acoustic Wave (SAW) filters and
additional IF circuitry - and you have a system solution that
enables the development of cost-effective multi-band, multimode
handsets offering superior talk and standby times in smaller form
factors.
radioOne Technology
MSM chipsets using radioOne technology offer the benefits of direct
conversion no matter what air interface is being used: CDMA, GSM,
GPRS or UMTS. Using advanced techniques developed by QCT to
enable high-dynamic-range receivers, radioOne ZIF technology solves
the problem of stringent interference specifications with which CDMA
phones must comply. The radioOne technology also incorporates the
frequency synthesis and passive elements used in converting baseband
signals to and from RF. For the UMTS receiver, a single external local
oscillator is used, which will provide the capabilities needed to operate
on systems around the world, and will simplify the procurement of parts
and greatly reduce the cost of designing UMTS handsets.
The MSM6250 system solution supports data rates of up to 384
kbps, providing manufacturers worldwide with the ability to
develop consumer products that offer voice, position location
technologies, high-speed data, and video over wireless networks.
Network operators will also benefit from the cost efficiencies and
rapid time-to-market that the solution delivers for next-generation
services.
gpsOne Technology
By integrating the gpsOne baseband functionality, the MSM6250 chipset
provides an Assisted-GPS (A-GPS) solution with unmatched acquisition
speed, accuracy and sensitivity for services on GSM/GPRS/UMTS networks
worldwide. This integrated solution addresses the rapidly expanding market
for location-based services and will enable handset manufacturers to
develop products to support a wide variety of applications with three
standards-approved modes of operation: Mobile-Assisted, Mobile-Based
and Standalone GPS.
From circuit-switched high-end voice to packet-switched high-
speed data, from audio to images and video, the MSM6250
system solution supports a wide range of consumer products
offering a variety of capabilities, including Personal Digital
Assistant (PDA) and Internet applications such as e-mail, e-
commerce, multimedia file transfer, video streaming, picture
messaging, Web access and more.
The gpsOne capability enabled by the MSM6250 chipset can be accessed
via QUALCOMM's Launchpad™ suite. The gpsOne API component of the
Launchpad suite provides applications with easy access to location
information and control over their operation. The MSM6250 chip leverages
SnapTrack®'s proven A-GPS algorithms for multipath mitigation, power
reduction, sensitivity enhancement and minimized wireless bandwidth
utilization. These leading-edge algorithms, combined with the high level of
integration, provide unmatched GPS acquisition speed, accuracy and
sensitivity, while minimizing handset cost, space requirements and battery
usage, and reducing communications bandwidth.
The MSM6250 system solution consists of the MSM6250
baseband processor, direct conversion RFL6200™ and
RFR6200™ receive devices, the direct conversion RTR6250™
GSM transceiver and UMTS transmit device, powerOne™ series
PM6650™ power management device, a compatible power
amplifier device, a complete UMTS/GSM/GPRS protocol stack and
multimedia system software. These devices, plus the system
software, perform all of the signal processing and power
management in the subscriber unit.
