WiMAX is a coined term or acronym meaning worldwide interoperability for microwave access (WiMAX). What WiMAX is however at its heart is a standards initiative. Its purpose is to ensure that the broadband wireless radios manufactured for customer use interoperate from vendor to vendor.

The primary advantages of the WiMAX standard are to enable the adoption of advanced radio features in a uniform fashion and reduce costs for all of the radios made by companies who are part of the WiMAX Forum”— a standards body formed to ensure interoperability via testing.

WiMAX is a standards-based technology that can replace existing wired connection modes to provide wireless broadband access for the last mile. Working in the 2 GHz to 66 GHz band, WiMAX products have excellent wireless propagation features.

WiMAX provides fixed, mobile and portable wireless broadband connections. It can provide mobile wireless broadband connection without direct line-of-sight (LOS) base stations. In the typical unit deployment with a radius of five to 15 miles, it can simultaneously support several hundred business users with a T-1 connection speed or several thousand home users with a DSL connection speed.
