4GV is a suite of voice speech codecs developed by Qualcomm for use in CDMA 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 on CDMA2000 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, or Enhanced 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 a wideband speech codec that provides high-quality voice communication over a wide range of bit rates but with a wider frequency than EVRC-B2.
