Qualcomm Inc. has introduced new Mobile Station Modem (MSM) MSM6246 HSDPA and MSM6290 HSUPA chipsets, which the company claims will reduce the cost of W-CDMA (UMTS) mobile broadband handsets.

The two chipsets, already sampling, have new power-saving features that promise to improve performance and extend battery life of HSDPA and HSUPA handsets, with standby time of more than 37 days.

"With more than 140 mobile operators in 65 countries now offering commercial HSPA services, mobile broadband is quickly gaining economies of scale," said Alex Sinclair, chief technology officer of the GSMA. "We are pleased to see the mobile ecosystem making HSPA ever more affordable, enabling more and more people to enjoy high-speed access to multimedia services while on the move."

"The proliferation of HSPA is helping drive the growth of popular Internet and social networking applications in the mobile space, and we have made great strides in ensuring that these technologies are accessible to a wide base of consumers," said Alex Katouzian, VP of product management for Qualcomm CDMA Technologies. "With these latest additions to our road map, we are working closely with our device manufacturer customers, carrier partners and the GSMA to actively help drive down the costs for new mobile broadband handsets that users everywhere are increasingly demanding."

The MSM6246 chipset will support 3.6Mbps HSDPA for advanced services such as high-resolution video downloads and Web 2.0 browsing. The MSM6290 HSUPA chipset supports speeds up to 7.2Mbps on the downlink and 5.76Mbps on the uplink, enabling popular applications such as social networking and user-generated multimedia sharing. The two products are drop-in replacements for each other, with power management, software and RF compatibility. Both products interface with the RTR6285 single-chip CMOS transceiver.

The MSM6246 HSDPA chipset features 3Mpixel camera support; QVGA video playback; integrated A-GPS and high-speed USB support. The MSM6290 HSUPA chipset features 5Mpixel camera support; WQVGA video playback; integrated A-GPS, 3D graphics and high-speed USB support.

In addition, the two products come in 10mm x 10mm package sizes that represent a nearly 50 percent reduction in package footprint from previous-generation baseband solutions. This size reduction will enable next-generation mobile broadband devices that are fully featured, slim, stylish and powerful in functionality, the company said.
