Qualcomm takes multi-mode multi-band to the next level
Posted: 14-Feb-2005 [Source: Qualcomm]

[Qualcomm announces two new chipsets to their line-up supporting true global roaming between WCDMA markets.]

Qualcomm today announced a tri-band WCDMA (UMTS)/HSDPA and quad-band GSM/GPRS/EDGE (EGPRS) radioOne(R) solution to enable true global roaming between WCDMA markets in Europe, North America and Asia. The introduction of the RFR6220(TM) receiver for 850 MHz markets adds to Qualcomm's commercially available RTR6250(TM) transceiver and RFR6250(TM) receiver. This complete solution will provide global support for WCDMA 850/1900/2100 MHz and EGPRS 850/900/1800/1900 MHz.

This integrated solution also includes support for Qualcomm's gpsOne(R) position location technology. Qualcomm's Mobile Station Modem(TM) (MSM(TM)) MSM6255(TM) chipset for WCDMA/EGPRS and MSM6275(TM) chipset for WCDMA/HSDPA/EGPRS are optimized for the RTR6250, RFR6250 and RFR6220 solutions. Handset manufacturers can implement one of two RF configurations for market-specific devices:

(1) RTR6250/RFR6250 for quad-band EGPRS, dual-band WCDMA 1900/2100 MHz and gpsOne support or

(2) RTR6250/RFR6250/RFR6220 for quad-band EGPRS, tri-band WCDMA 850/1900/2100 MHz and gpsOne support.

Engineering samples of the RFR6220 device are expected to ship in the second quarter of calendar 2005. The RFR6250 and RTR6250 devices are commercially available today.

"We've added a tri-band WCDMA RF chipset to our extensive WCDMA portfolio to enable global roaming across Europe, North America and Asia," said Dr. Sanjay K. Jha, president of QUALCOMM CDMA Technologies. "This is an industry first that further strengthens our WCDMA/HSDPA product portfolio."

Qualcomm's latest radioOne configurations offer flexible design solutions to handset manufacturers developing devices for multi-tiered global markets. Handset designs that support tri-band WCDMA with the RTR6250/RFR6250/RFR6220 configuration can be reused to support single- or dual-band WCDMA by excluding the RFR6220 device -- reducing parts count while maximizing development efforts to ensure cost-effective 3G solutions.

The MSM6255 chipset is a highly integrated solution for WCDMA and EGPRS networks worldwide and is optimized to deliver in-demand mainstream multimedia applications, including streaming audio and video, high-quality snapshots and location-based services.

Qualcomm'sMSM6275 chipset solution for WCDMA/HSDPA and EGPRS provides increased processing power and graphics performance at low power consumption to enable the highest quality audiovisual and gaming graphics on cost-effective, multiband, multimode handsets with smaller form factors.
