Ericsson Showcase World's Best Voice Quality for Mobile Networks

 Ericsson (NASDAQ: ERIC) 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.

Results from consumer trials show that consumers appreciate the higher voice quality and make more and longer calls. The higher voice quality is ideal for telephone meetings and can contribute to a reduction of business traveling which will improve productivity and lower environmental impact.

"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".

Ericsson performs demonstrations of the AMR Wideband technology during the Mobile World Conference in Barcelona, Spain.
