MSM6500™ CHIPSET SOLUTION
The Mobile Station (MS) collects measurements from the GPS
constellation and the cellular/PCS network, and then sends the
information to the Position Determination Entity (PDE), which
optimizes the position location calculation based on existing
information. gpsOne technology will enable consumer-priced,
position-capable CDMA handsets. The chipset block diagram
illustrates the baseline architecture for the MSM6500 and
CDMA/GPS terminal devices.
MSM6500 Device Features
The MSM6500 system solution consists of the MSM6500, RFL6000,
RFR6000, RFT6100 or RTR6300, PM6650, DMSS™ (Dual-Mode
Subscriber Software™) and SURF6500™ platform, and features:
• CDMA2000 1xEV-DO (IS-856) support
• CDMA2000 1X (IS-2000)
• GSM/GPRS support, 3GPP compliant Revision 99 class B,
multi-slot class 10 data services
The MSM6500 chipset and system software is also capable of
operating in a standalone gpsOne mode, in which the handset acts
as a GPS receiver.
• Receive diversity on CDMA2000 1X and 1xEV-DO systems
• High-performance ARM926EJ-S microprocessor core with
memory management unit (MMU)
