Ericsson Debuts Adaptive Multi Rate Wideband for GSM

Ericsson introduced an Adaptive Multi Rate (AMR) Wideband technology to boost the audio quality of voice calls in mobile networks. The technology can be implemented in both GSM and WCDMA/HSPA networks, and provides hi-fi quality, crystal-clear sounds on mobile handsets that support the feature.


AMR (Adaptive Multi Rate) Wideband is a GSM/WCDMA standardized speech technology that enhances voice quality and clarity in mobile networks to noticeably higher levels than today's mobile and fixed telephony networks, even in whispered conversations or environments with high background noise.

Ericsson said the new speech-compression algorithm doubles voice bandwidth without extra radio and transmission requirements.

"We are ready to roll-out this impressive voice quality feature in all Ericsson-supplied GSM and WCDMA/HSPA networks in the world," says Ulf Ewaldsson, Vice President and Head of Product Area Radio, Ericsson. "This is the starting point of a voice quality revolution that will change telephony as we know it today".
