Survey of IEEE 802.11 Physical and MAC Layer Protocols
Wireless broadband technologies furnish omnipresent broadband admission to wireless users, enabling services that were obtainable merely to wire line users. In this paper, the authors condense growing wireless broadband admission technologies, fluctuating from WLANs (Wireless Local Area Networks) to satellite communications. They clarify the latest standards in the IEEE 802.11 and IEEE 802.16 families in detail. The MAC layer mechanisms of IEEE 802.11e, 802.11n and 802.11s standards are clarified as well as the point to-multipoint and Mesh modes of IEEE 802.16. The present mobility correction to the WiMAX relations, IEEE 802.16e, is additionally described. Wireless technologies can be categorized established on their coverage areas. IEEE 802.11 and ETSI HiperLAN standards are believed for wireless admission in innate areas.
