The IEEE 802.16 Working Group on Broadband Wireless
Access Standards develops standards and recommended practices to support the
development and deployment of broadband Wireless Metropolitan Area Networks.
IEEE 802.16 is a unit of the IEEE 802 LAN/MAN Standards Committee. IEEE 802.16
addresses the "first-mile/last-mile" connection in wireless
metropolitan area networks. It focuses on the efficient use of bandwidth
between 10 and 66 GHz (the 2 to 11 GHz region with PMP and optional Mesh
topologies by the end of 2002) and defines a medium access control (MAC) layer that
supports multiple physical layer specifications customized for the frequency
band of use. A closely related body, WiMAX is comprised of companies who are
committed to the open interoperability of all products used for broadband
wireless access. The purpose of WiMAX is to promote deployment of broadband
wireless access networks by using a global standard and certifying
interoperability of products and technology. WiMAX supports IEEE 802.16
standard and propose and promote access profiles for IEEE 802.16 standard. It
also certifies interoperability levels both in network and the cell.
