4GV is a suite of voicespeech codecs developed byQualcomm for use inCDMA networks.[1] The suite allows network operators to dynamically prioritize voice quality, which can help to increase network capacity while maintaining voice quality. The 4GV suite includes EVRC-B and EVRC-WB.[1]
Qualcomm introduced the 4GV suite to increase network capacity onCDMA2000 Networks significantly.[1] This technology allows for more efficient use of network resources, leading to improved call quality and increased network capacity.
The suite includes two codecs: EVRC-B and EVRC-WB. EVRC-B, orEnhanced Variable Rate Codec B, is a speech codec that provides high-quality voice communication over a wide range of bit rates2. EVRC-WB, or Enhanced Variable Rate Codec Wideband, is awideband speech codec that provides high-quality voice communication over a wide range of bit rates but with a wider frequency than EVRC-B2.
