Operator Three UK has turned on high definition (HD) Voice support across its 3G network in the UK. Three’s customers are already making tens of thousands of High Definition calls every day, and as more and more handsets come equipped with the technology this figure is expected to grow rapidly. The HD Voice technology is supported by Nokia Siemens Networks which has equipped all of Three UK’s 3G network with its radio technology. There are currently 31 networks with HD Voice technology around the world. Nokia Siemens Networks has deployed its offering in 14 out of these 31 networks.
But what is HD Voice and what does this news actually mean to a subscriber? HD Voice filters out background noises and uses a wider range of sound (50–7000 Hz) as compared with traditional voice (300–3400 Hz). This results in much better sound quality. So you can hear the person on the other end of your mobile phone conversation even in a very noisy place, like a café or on the road. Three UK is already providing this step-change voice service to its own customers and says it’s working now on bringing in cross-network HD Voice calls.
