Are you tired of the crappy voice you hear at the other end when you answer a phone call from your girlfriend? No, I don't want to tell you to dump her! Read along please and don't make any misjudged actions you will regret later :).

I want to tell you that Ericsson and T-Mobile are now testing some miraculous new technology called AMR Wideband (Adaptive Multi-Rate), which is a voice coding technology that will help make high fidelity phone calls so you won't think that the guy at the other end is some kind of monster with damaged vocal chords. The field trial of this technology has taken place this summer in Cologne and Hamburg (Europe that is), and most of the ones that tried it have reported a serious increase in the voice quality of their phone conversations and thus making longer phone calls.

Klaus-J?rgen Krath, Vice President RAN Engineering at T Mobile International, has declared that "AMR Wideband technology delivers voice quality that was hitherto unknown. The technology therefore gives T-Mobile an excellent chance to further improve quality from a customer standpoint, and to boost customer satisfaction for the long term. The field trial has produced key findings from which we stand to benefit when we deploy the technology in our network in the future."

The AMR Wideband voice codec developed by Ericsson is intended to be used on GSM and UMTS mobile networks, and to improve the overall voice quality of the voice transmission between telecommunication routers and the mobile phones. The actual method of improving the quality of voice transmission is being based on a voice compression algorithm that doubles the voice transmission bandwidth without a need to increase the transport channel performance of the mobile networks.

A purpose that has been reached because with the AMR Wideband activated, the two individuals talking on the mobile phone will be able to easily understand what the other is saying, even if this is done by whisper or in very noisy environments.
