Ericsson showcase world’s best voice quality for mobile networks
Ericsson has introduced AMR Wideband, the latest technology for high-quality voice calls, in mobile networks and is demonstrating it at the Mobile World Congress in Barcelona, Spain. The technology can be implemented in both GSM and WCDMA/HSPA networks, and provides hi-fi quality, crystal-clear sounds on mobiles 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. The new speech-compression algorithm doubles voice bandwidth without extra radio and transmission requirements.
