Wireless Metropolitan Area Networks and WiMax: IEEE 802.16

• Wireless Metropolitan Area Networks (WiMANs) provide wireless connectivity across a geographical area the size of a city.
• Broadband access technology provides broadband data rates for last mile connectivity to businesses, homes, and network bridging.
• Currently, there are a variety of technologies, speeds, costs, coverage ranges, spectrums, etc. in the market, which is fragmented among technologies.
• Proprietary solutions include Free Space Optical LMDS, MMDS, and wireless multi-hop mesh networks based on 802.11, while standards-based solutions are provided by IEEE 802 architecture.
• IEEE 802 architecture includes physical layer functions, medium access control (MAC) layer functions, and logical link control (LLC) layer functions.
• IEEE 802.16, also called WiMAX, uses wireless links with microwave or millimeter wave radios and licensed spectrum to create wireless metropolitan area networks (WMANs) that provide public network service to fee-paying customers.
• WiMAX uses point-to-multipoint architecture with stationary rooftop or tower-mounted antennas and provides efficient transport of heterogeneous traffic supporting quality of service (QoS).
• The WiMAX Forum, an industry consortium, was formed to promote the 802.16 standards and to develop interoperability specifications.
• WiMAX network reference model includes Access Service Network (ASN), Network Access Provider (NAP), Connectivity Service Network (CSN), Network Service Provider (NSP), and ASN Gateway.
• IEEE 802.16 protocol architecture includes physical and transmission layer functions, medium access control layer functions, and convergence layer functions.
• IEEE 802.16 MAC PDU format includes header, payload, and CRC.
• IEEE 802.16 physical layer includes Wireless MAN-SC, Wireless MAN-OFDM, and Wireless MAN-OFDMA.
