There are a number of reasons why mobile WiMAX will live up to the hype that preceded the ratification of the Institute of Electrical and Electronics Engineers, Inc (IEEE) 802.16e-2005 standard. The main reason that WiMAX will succeed where others have failed is that it is the right technology at the right time to fill a technology gap. For this reason the standard has wide industry support and financial backing. Make no mistake, WiMAX will be nearly ubiquitous within five years, and it will provide cost-effective mobile broadband access for enterprises that does not exist today.
