WiMAX is a BWA technology that has gained a very wide acceptance among major
broadband service providers and equipment manufactures. Because of its technical
soundness and its wide acceptance in the industry, it is poised to be the most widely
deployed BWA in the world.
470 Chapter 15
This chapter discusses some of the technology of WiMAX and how it fits within the
context of delivering carrier-grade Ethernet services. The terms WiMAX and IEEE
802.16 are used interchangeably; even though, the industry standard??“accepted meaning
of WiMAX may not exactly overlap with that of IEEE 802.16.
Technology Description
WiMAX is a shared medium point-to-multipoint multi-user wireless communication
technology where multitudes of devices share a common medium??”a band of RF spectrum
??”to serve their communication needs. WiMAX offers a multiple access protocol
that is highly flexible yet highly efficient in its use of limited resources. It allows for
a diverse set of physical layer protocols, each of which makes very efficient use of the
spectrum. And it was designed from the ground up with the demanding QoS needs of
applications in mind.
