CAPE TOWN (WiMAX Day). In South Africa, the race to build the biggest and fastest WiMAX network is hotly contested. A recent report in MyBroadband said MWEB is advancing quickly with trials in Cape Town, Johannesburg, Gauteng, Soweto and Boksburg. The largest competitor for MWeb is the incumbent operator Telkom, also quickly launching a WiMAX network. However the report said that MWeb is confident in its ability to compete against Telkom, as the company does so with success on other Internet products. MWeb has yet to be issued a commercial license for WiMAX spectrum, and currently is using spectrum only for testing.
