GSA: 116 mobile operators have commercially launched HD voice services

Some 116 mobile operators in 75 countries have commercially launched HD (high-definition) voice services, according to the Global Mobile Suppliers Association (GSA). A new report from the association confirmed that the number of mobile operators now offering HD voice services is more than 30 per cent higher than a year ago. Mobile HD voice uses Adaptive Multi Rate Wideband (W-AMR) technology, enabling high-quality voice calls in supporting mobile networks and an improved user experience for calls between mobile phones supporting the feature. The majority of operators offer HD voice service over a single radio access network, although some offer the service over more than one network system. Meanwhile 71 operators are investing in VoLTE studies, trials or deployments, including 11 that have commercially launched HD voice service. Release
