Chip set addresses mainstream handsets

Aimed at mainstream handsets, Qualcomm's latest chip set double system capacity for CDMA2000 1X networks without changes to air interface standards. The Mobile Station Modem (MSM) MSM6125 chip set features mobile receive diversity and advanced position-location capabilities, such as increased GPS sensitivity, enhanced GPS filtering, and simultaneous operation of voice and GPS positioning.

These enhancements help improve data throughput. Handset makers can also significantly reduce their development costs and time-to-market for new mass-market devices by leveraging existing EV-DO handset designs and applications.

The chip set's 4GV solution is a core voice codec suite that increases system capacity by giving network operators the flexibility to prioritize voice quality or network capacity as needed. The company's mobile receive diversity solutions use an additional antenna and associated receive chain to deliver higher data throughput and significant increases in network capacity, enhance network performance on the forward link and reduce the incidence of dropped calls.

The complete MSM6125 solution includes the RFR6500 or RFR6185 radioOne receive, the RFT6150 transmit, and the PM6650 power-management devices. For more information about the chip set, visit www.cdmatech.com/msm6125.
