Canadian 3G cellular operator Wind Mobile is deploying Huawei Technologies’ High Definition (HD) voice services for its subscribers, based on an implementation of ‘Wide Band Adaptive Multi-Rate (AMR)’ in the core network, and is the first wireless provider in Canada to use the service, the Chinese vendor said. According to Marius Armeanca, CTO at Wind Mobile: ‘The HD voice services Wind is using brings better quality voice to end users … Huawei was instrumental in helping us create a technology that will do for phones what High Definition did for television. With the customised Wide Band AMR Service, our customers will realise superior voice quality and an improved overall experience.’ Wide Band AMR is a speech coding standard using a wider bandwidth of 50Hz-7000Hz compared to narrowband quality bandwidth of roughly 300Hz-3400Hz.
