By summer 2003, Qualcomm will begin sampling its MSM6500 chipset which will let manufacturers make devices that work on CDMA, CDMA2000 1xRTT/1xEV-DO and GSM/GPRS networks.
Qualcomm has announced details regarding its MSM6500 Mobile Station Modem (MSM) chipset and system software, a high-capacity, high-speed wireless data solution that supports the CDMA2000 1X and CDMA2000 1xEV-DO standards, as well as roaming on GSM/GPRS systems. Samples of the MSM6500 chipset are expected to ship in the second quarter of calendar 2003, which means devices utilizing the chipset could arrive as early as in late 2003.
Capable of peak wireless data rates of 2.4 Mbps on the forward link, the MSM6500 solution also integrates USB On-The-Go (OTG) host controller functionality that will enable wireless handsets to communicate directly with accessories such as printers, digital cameras, keyboards, and CD-ROMs. Building on QUALCOMM's MSM6100 architecture, the MSM6500 chipset also integrates the ARM926EJ-S processor with the ARM Jazelle Java accelerator to speed up J2ME applications, two low-power, high-performance QDSP4000 Digital Signal Processor (DSP) cores and a wideband stereo codec for enhanced digital audio applications.
The MSM6500 chipset also supports GSM and GPRS functionality, enabling the chipset to support all major telecom standards worldwide except for WCDMA - in theory opening up for true global roaming with just one handset. The GSM/GPRS modem is based on Release 99 of the GSM and GPRS standard, and supports class B, multislot class 8 operation, as well as EFR, FR, HR and AMR vocoders.
Also supported is the advanced feature set of QUALCOMM's Launchpad suite of technologies, including MPEG-4 encoding and decoding, MP3 audio decoding, 2D/3D graphics acceleration for gaming, Compact Media Extension (CMX) MIDI synthesizer, QUALCOMM's Qcamera digital interface, fast JPEG encoding/decoding, Bluetooth technology for wireless connectivity and USB OTG. To enable location-based services and applications, the MSM6500 chipset and system software integrate QUALCOMM's gpsOne solution, which is also capable of operating in a standalone mode, in which the handset using the chip would act as a GPS receiver.
