WiMAX Networks

Part of the Optical Networks book series (OPNW)


WiMAX (worldwide interoperability for microwave access) network is the wireless metropolitan area broadband access solution built in compliance with the IEEE 802.16 standard. This network supports high data rates with extended service coverage for up to several tens of kilometers. It can also fill the gap between 3G cellular network and local area wireless network such as WiFi. Multiservice-oriented quality of service (QoS) and vehicular speed mobility are fully accommodated in WiMAX standardization. The standard defines a mandatory point-to-multipoint (PMP) operation mode along with an optional mesh mode for enhanced network scalability and user mobility. In providing a technical guideline for this emerging wireless technology, this chapter proceeds by addressing several fundamental topics on WiMAX, including (1) basic knowledge, as per IEEE 802.16 specification, on the operating radio frequency bands, physical layer interfaces, and media access control (MAC) sublayers of a WiMAX system; (2) MAC services via different physical interfaces, QoS mechanisms, and resource management issues for PMP operation mode; (3) mesh mode-specific scheduling, routing, and QoS provisioning in WiMAX networks; and (4) mobility in WiMAX networks, with main focus on handover techniques between both homogeneous and heterogeneous network interfaces.
