Much of the current excitement surrounding WiMAX is driven by both technological and commercial reasons. The industry is facing tremendous pressure to reduce cellular network costs, which is possible by achieving greater efficiency of the wireless spectrum than is currently feasible with today’s mobile networks. This efficiency can be achieved by using a mixture of advanced technologies that allow very quick changes to user traffic modulation and coding schemes, in conjunction with advanced error correction and traffic scheduling schemes.

WiMAX builds on a network equipment design philosophy, similar to Ethernet and WLAN specifications, that has significantly reduced costs and enables increased efficiency within the enterprise environment. Its challenge is to prove that such benefits can scale
and can be applied to wider public networks.
