The state-owned broadcasting network owner and telco Sentech has said it plans to phase out its MyWireless and Biznet wireless internet services over the medium term as it moves towards WiMAX technology. Sentech was the first company in South Africa to launch a wireless broadband service, introducing services in the 3.5GHz band under the brand MyWireless in 2002. However, due to financial constraints there has only been a limited rollout to parts of Johannesburg, Cape Town, Durban, Pretoria and Nelspruit. Having previously targeted mainly the residential and SME markets, in November 2005 Sentech launched BizNet Xpress, a package of fixed wireless solutions for the larger business and corporate user. In March 2007 Sentech upgraded all its broadband plans to offer a larger data download limit, though the MyWireless service, which is based on IPWireless technology, had only around 2,000 to 3,000 users by mid-2007. Sentech recently received the first ZAR500 million (USD65 million) investment from the government which it plans to use to deploy 3.5GHz WiMAX networks to replace the existing fixed wireless products. A time scale for the switch to WiMAX has not been given.
