Qualcomm says that it has developed new enhancements to CDMA2000 network technology which supports more than double today's capacity of 35 simultaneous calls in 1.25 MHz of spectrum while delivering the same level of voice quality.

"This latest enhancement to CDMA2000 technology will allow operators to continue leveraging their existing 3G networks far into the future," said Cristiano Amon, senior vice president of product management for Qualcomm CDMA Technologies. "As wireless subscribers around the world grow increasingly sophisticated in their demands, the unsurpassed levels of efficiency that CDMA2000 delivers will enable network operators to get more from their spectrum in an efficient and economical manner."

The capacity enhancements to CDMA2000 technology are featured in certain products from Qualcomm's new Cell Site Modem (CSM) CSM8xxx-series chipsets. The target schedule for the new CSM8xxx-series solutions supports complete interoperability testing and commercialization by 2010.

Featuring reverse link interference cancellation and other advanced radio techniques, these products will enable existing CDMA2000 networks to deliver new voice capabilities through a simple channel card upgrade while leveraging most radio access network investments. In addition, the voice capacity enhancements can be combined with EV-DO Rev. B mobile broadband in the same base station.
