WiMAX actually stands for Worldwide Inter operability for Microwave Access, and is a wireless communication standard. Of the standards currently being developed for 4G it is the closest in practice to current Wi-Fi, though it provides several notable advantages. WiMAX was developed in 2001 and is described by the WiMAX forum as "a standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL". This “last mile” refers to the often difficult process of getting access to a consumer from a local data station, be it in the form of a telephone cable, wireless device or other broadcasting technology.
WiMAX has a number of front-line uses, including at-home and mobile Internet access. Because of its large radius and relatively low cost to implement when compared to 3G or xDSL the technology can not only compete in a local market but also be used for last-mile access in remote locations. In addition, the standard can be used as backbone for cellular technology, either by replacing current technologies or acting as an overlay in order to increase capacity. It can also be used to provide “triple-play” service, which involves the deployment of two bandwidth-intensive operations and one less bandwidth-intensive operation over a single connection. This can include, for example, high speed Internet access, Internet television and a standard phone line.
