WiMAX


OVERVIEW

Being fully packet-based, providing QoS and relying on OFDM, WiMAX is seen as a foretaste of mobile communications of the fourth generation. Now that the first WiMAX equipment has been certified, interoperability between fixed broadband wireless access systems comes true.
The introduction course will give an overview of the fixed flavour of the IEEE 802.16-2004 standard, on which the WiMAX certification has been grafted. After a brief review of some wireless concepts, the various aspects of the fixed WiMAX technology will be covered: OFDM, maximizing the coverage and capacity of the wireless channel, access of the network, QoS, security and management. Finally, a case study will illustrate the trade-offs that have to be made when designing a WiMAX network.
