802.16   WiMAX

Definition:

As a sister technology to Wi-Fi, the IEEE 802.16 specification outlines technology for Wireless Metro Area Network (MAN). WiMAX actually stands for Worldwide Interoperability for Microwave Access, which was established by a consortium to promote the technology called the WiMAX Forum. The 802.16 MAC uses a variable length designed to increase the efficiency of the standard. Multiple MAC PDUs-Packet Data Units may be concatenated (combined) into a single burst to save PHY-PHYsical overhead. There are various revisions of the IEEE standard such as 802.16REVd (now known as 802.16-2004) for fixed wireless and to call 802.16e nomadic wireless or semi-mobile wireless. 802.16 can use TDMA-Time Division Multiple Access where each data packet is assigned a unique time slot, FDMA-Frequency Division Multiple Access for both full duplex (simultaneous two-way) and half-duplex (one direction at a time) or other transmission systems.
