WiMAX (Wireless metropolitan access networks - MANs) is also known as IEEE 802.16. It's a specification for fixed broadband wireless networks that use a point-to-multipoint architecture. Occasionally the technology is referred to as WirelessMAN or the Air Interface Standard
"Will WiMax ever get its due as a major player in government metropolitan area networks? Its a great technology which always seems to be waiting on the horizon with experts claiming it's just a year or two away from major deployment. But WiMax has been waiting right there on the horizon since 2002. I tend to think of WiMax as a bit like George Jetsons flying car. Great idea. Functional examples exist in several places. But broad penetration never quite takes off."
