Wi-Fi is the name given by the Wi-Fi Alliance to the IEEE 802.11 suite of standards. 802.11 defined the initial standard for wireless local area networks (WLANs), but it was considered too slow for some appli- cations and so was superseded by the extensions 802.11a and 802.11b, and later by 802.11g (with the release of 802.11n still pending). At its most basic, Wi

The IEEE 802.11 MAC protocol is a carrier sense multiple access protocol with collision avoidance (CSMA/CA). Recall from our study of Ethernet in section 5.5 that a CSMA protocol first senses the channel to determine if the channel is “busy” with the transmission of a frame from some other station. In the 802.11 specification, the physical layer monitors the energy level on the radio frequency

IEEE 802.11 Architecture Architecture Components An 802.11 LAN is based on a cellular architecture where the system is subdivided into cells. Each cell (called Basic Service Set, or BSS , in the 802.11 nomenclature) is controlled by a Base Station (called Access Point or, in short, AP ). Although a wireless LAN may be formed by a single cell, with a single Access Point, (and as will be

Wi-Fi is the name given by the Wi-Fi Alliance to the IEEE 802.11 suite of standards. 802.11 defined the initial standard for wireless local area networks (WLANs), but it was considered too slow for some appli- cations and so was superseded by the extensions 802.11a and 802.11b, and later by 802.11g (with the release of 802.11n still pending).
