Real time mobile communication sysytems are still using Narrowband speech codec, why they are not completely replaced with wideband speech codec.

I think now adays bandwidth criteria is not a serious issue as we are using VoIp and 4G.

Can you please through some light on this.

G.711 (a-law or u-law) is a fixed 64Kbps, not "32 kbps or lower". He must have been thinking G.726.

We have benchmarked wideband codec Mhz performance on a variety of our VoIP embedded target systems and found that in some cases, the wideband codec Mhz requirement is still less than the worst-case narrowband codec Mhz requirement (G729AB). This means that some wideband codecs may be introduced into an existing system (at least, our softDSP systems) without worry of exceeding processing cycle limits. - jcline@d2tech.com
