WiMAX (802.16d/e) is a standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to wired broadband like cable and DSL. This makes WiMAX the perfect choice for deployment in the African environment as it offers a simpler, cheaper and easier deployment than traditional methods. The WiMAX (802.16d) standard provides fixed broadband access whilst the WiMAX (802.16e) standard provides fixed, nomadic and portable mobile wireless broadband connectivity without the need for direct line-of-sight with a base station. In a typical cell radius deployment of three to ten kilometers, WiMAX Forum Certified™ systems can be expected to deliver capacity of up to 40 Mbps per channel, for fixed and portable access applications (highly dependent on many situational and technical factors).
This is enough bandwidth to simultaneously support hundreds of businesses with E-1 (2048 kbps) speed connectivity and thousands of residences with ADSL speed connectivity. Mobile network deployments can be expected to provide up to 15 Mbps of capacity within a typical cell radius deployment of up to three kilometers.
WiMAX technology has been incorporated in notebook computers, Smartphones, and widely deployed in Desktop Routers, USB Dongles and Portable Routers. Other applications catering to enterprise types of deployments have been highly successful due to versatility, security and reliability. In some places, WiMAX has been also been deployed for Backhaul purposes for traffic offload of other technologies, as an example it has allowed urban areas and cities to become “metro zones” for portable outdoor broadband wireless access using WiFi connectivity.
WiMAX shall still see growth and further deployments for years to come due to its maturity, efficiency, reliability and lower relative cost to competing technologies, both in commercial and vertical market deployments.
