Vodacom South Africa says it has made the country\'s first ever Voice over LTE (VoLTE) call over its 4G/LTE network., Telecompaper.com reports on Sept 26, 2014. Typically reserved for data, the move to use 4G/LTE technology to carry voice traffic will in the future mean better call quality for consumers and a more efficient use of network resources. The date for the commercial launch of the service will depend on the availability of compatible devices. Vodacom is working with handset manufacturers to ensure the technology is embedded in local handsets. This latest development is part of the Vodacom\'s on-going ZAR 9 billion network investment program. On top of recently implementing enhanced voice services (HD Voice plus) and making the first VoLTE call, Vodacom has also been adding base stations, and expanding fiber optic infrastructure to improve both the reach and quality of coverage. Vodacom was the first operator to achieve true 4G (LTE-Advanced) on a live mobile network in South Africa. The first commercial test of the 4G network resulted in download speeds exceeding 300 Mbps.
