MTN SA launches HD Voice on 3G network

21 Aug 2014

South African cellco MTN has launched high definition (HD) Voice technology on its 3G network using the Adaptive Multi-Rate Wideband (AMR-WB) coding standard, enabling high-quality voice calls and an improved user experience, MyBroadband reports. Eben Albertyn, chief technology officer at MTN SA, revealed that in order to experience the benefits of HD Voice, both the caller and receiver must have compatible handsets, adding: ‘Currently, there are no HD voice calls on LTE, so this technology applies to 3G calls’. The executive also pointed out that due to very limited handset support for AMR-WB on 2G calls, MTN has not activated the technology on its 2G network.

MTN is the first operator in the country to deploy HD Voice. Rival cellco Vodacom reportedly said in September 2012 that it was evaluating the commercial viability of the technology, while Cell C revealed at the time that it had ‘no immediate plans’ to deploy HD Voice.
