The 802.16 Standard FamilyIEEE 802.16 WG formed in 1998 to develop a standard for Wireless MAN (primarily Fixed Wireless)Initially 10-66 GHz band considered, later modified to focus on 2-11GHz NLOSIEEE 802-16-2004 standard ratified in 2004 DEC 2005 specification for 802.16e (802-16-2005) was completed adding mobility support and operation in 2-6 GHz among other enhancements.

The 802.16 standards have a very broad scope with many incompatible optionsWorld-wide Interoperability for Microwave Accessp yWiMAX (similar to WiFi) is not a technology but a certification framework.Framework◦ Use of the IEEE 802.16 Air interface◦ Certify Interoperability at the air interface as well as the

networke o◦ Promotes the use of BWA The WiMAX forum defines commercial “profiles” and promoted interoperability of products through testing and promoted interoperability of products through testing and certification
