- Mobile HD voice is high quality voice service which enables high quality voice calls as it cuts down the background noise often heard on a regular call.
- This service is based on AMR (Adaptive Multi Rate) wideband technology (W-AMR) which operates with nine different bit rates, providing high quality voice calls.
- Compared to the current narrow-band speech codec device, the W-AMR speech-compression algorithm doubles voice bandwidth and produces better results.
