Rohde & Schwarz announces that its CMU200 universal radio communication tester now supports Enhanced Variable Rate Codec (EVRC-B) functionality, which will soon be incorporated in CDMA2000 wireless networks. EVRC-B gives wireless service providers the ability to dynamically adjust voice capacity on their network according to traffic conditions. EVRC compresses each 20 ms of 8 kHz sampled speech and outputs full-rate, half-rate, quarter-rate and eighth-rate frames. EVRC-B, developed by QUALCOMM, Inc. as Fourth Generation Vocoder™ (4GV™), is the successor to EVRC that will soon be deployed in CDMA2000 networks. EVRC-B utilizes more efficient compression algorithms and allows selection of different operating points within the codec.
