MTN South Africa launches HD voice
South Africa’s MTN has reportedly launched high-definition (HD) voice technology on its 3G network in the country.
The mobile operator has used the adaptive multi-rate wideband (AMR-WB) coding standard, which is designed to enable high-quality voice calls and an improved end user experience.
“There are no [existing] HD voice calls on LTE, so this technology applies to 3G calls,” Eben Albertyn, CTO at MTN South Africa, told local reporters.
Albertyn also said that the service has not been launched on 2G calls due to limited handset support for AMR-WB on 2G networks.
MTN SA claims to be the first operator in the country to deploy HD voice, while networks in other African countries such as Uganda, Mauritius and Egypt had HD voice support in 2013.
