QUALCOMM announced its Fourth-Generation Vocoder (4GV) offering CDMA2000 1X and 1xEV-DO operators the flexibility to make network adjustments that prioritize voice quality and network capacity.
QUALCOMM said the new 4GV vocoder was specifically designed to leverage 1xEV-DO Rev. A, increasing the overall quality of end-to-end services for delay-sensitive applications such as VoIP. It supports both circuit-switched and packet-switched voice networks in a combined core. QUALCOMM claims it can increase capacity by up to 40% in narrowband networks compared to current vocoder solutions. It could also be used in wideband networks to offer superior voice quality enhancements, or in VoIP deployments to deliver better voice quality due to its QoS support.
QUALCOMM plans to support the 4GV solution in QUALCOMM’s Mobile Station Modem (MSM) CDMA2000 1X and 1xEV-DO chipsets, which also support the current vocoder solution. The company said wireless operators can realize even greater capacity improvements — up to double the capacity of today’s networks — by deploying 4GV in conjunction with receive diversity technology.
