RAN83 RAN831: 1: Wide Wideban band d AMR AMR Codec Codec Set Set (12 (12.65 .65,, 8.85 8.85,, 6.6) 6.6) Intr Intro oducti uctio on Wideband AMR speech codec enhances audio bandwidth from 300Hz - 3.4 KHz to 50Hz - 7kHz, which improves the transparency of calls. Enhanced lower frequency response makes voice warmer whilst enhanced higher frequency response improves the intimacy of voice. Benefits for the operator
Wideband AMR provides step-like improveme nt on voice quality over current telephony solutions without RAN capacity trade-offs since the bit rates are similar to AMR. The TrFO/TFO needed due to wideband AMR AMR (WB-AMR) reduces the need of CN CN investments.

Fun Functio ctiona nall desc descrripti iption on This feature supports a set of WB-AMR codec modes 12.65, 8.85 and 6.6 kbps. WB AMR provides better speech quality than narrowband AMR (NB-AM R) and fixed lines (G.711 PCM) between WB AMR capable UEs. To avoid downsampling from 16kHz to 8kHz, yielding to quality degradation, either TFO or TrFO is needed. The RNC handles the WB-AMR modes as well as multi-RABs similarly to NB-AMR. The codec modes 12.65, 8.85 and 6.6 kbps form a set of bit rates (TFS) that is assigned to every WB-AMR call. The limited TFCS in multi-RAB cases, the functionality of TFO/TrFO and managing the Iu Support Mode are similar to the feature AMR Codec Sets (12.2, 7.95, 5.90, 4.75) and (5.90, 4.75).
