Orange today revealed it will be launching HD Voice nationwide for customers on its mobile network in 2010 – the first such announcement by a UK operator.
HD Voice is said to deliver excellent audio quality to mobile calls and will be available to Orange customers with a HD Voice enabled handset. Orange says it is already working with handset manufacturers on the development of devices to be rolled out next year.
The 2010 launch follows two years of considerable investment in the Orange mobile network with expansion and technology upgrades across large areas of the UK.
Tom Alexander, CEO of Orange UK, said: "Orange is proud to be leading the industry into the next decade by announcing a new standard in voice innovation that will transform the mobile experience for customers in the UK. HD Voice really does inject a level of innovation into mobile phone calls, making it sound as if callers are actually in the same room. Once people have tried it, they won't want to go back."
HD Voice uses the WB-AMR (Wideband Adaptive Multi-Rate) speech codec, said to provide excellent audio quality due to a wider speech bandwidth of 50-7000 Hz compared to the current narrowband speech codec of 300-3400 Hz. The WB-AMR (Wideband Adaptive Multi-Rate) delivers significantly enhanced sound quality whilst utilising the same network resources, says Orange.
Further details on the Orange HD Voice roll out will be made during 2010.
