WiMax (Worldwide Interoperability for Microwave Access) is a wireless broadband technology, which supports point to multi-point (PMP) broadband wireless access.

WiMax is basically a new shorthand term for IEEE Standard 802.16, which was designed to support the European standards. 802.16's predecessors (like 802.11a) were not very accommodative of the European standards, per se. The IEEE wireless standard has a range of up to 30 miles, and can deliver broadband at around 75 megabits per second.
