Vodacom South Africa is preparing to launch its first WiMAX wireless broadband services in several major cities within the next few weeks. Local website MyBroadband reports that the cellco is currently trialling WiMAX services at speeds ranging from 128kbps to 1Mbps. Services are expected to be offered solely to business users. With no WiMAX licence of its own, Vodacom is using spectrum belonging to its subsidiary iBurst.
