The IEEE Standards Board established the IEEE 802.16 working group in 1999 to prepare formal specifications for global deployment of broadband wireless metropolitan area networks, which is officially called WirelessMAN. The IEEE 802.16 working group, which is a unit of the IEEE 802 LAN/MAN Standards Committee, is responsible for framing specifications of the IEEE 802.16 family standard, but not testing them. Thus, another industrial group was established in April 2001 called the WiMAX Forum. The acronym WiMAX expands to “Worldwide Interoperability for Microwave Access.’’ WiMAX Forum is on a mission to advance and certify compatibility and interoperability of broadband wireless products based on IEEE 802.16 family standards. Irrespective of the scope of the WiMAX Forum that aims to test equipments, the IEEE 802.16 family hails WiMAX from the WiMAX Forum, maybe because it is easier to use the word WiMAX rather than IEEE 802.16.
