IEEE 802.11 STANDARD
standard 802.11 (IEEE, 1999) specifies the most famous family of WLANs in which
many products are available. As the standard‘s number indicates, this standard
belongs to the group of 802.x LAN standards, e.g., 802.3 Ethernet or 802.5
Token Ring. This means that the standard specifies the physical and medium
access layer adapted to the special requirements of wireless LANs, but offers
the same interface as the others to higher layers to maintain interoperability.
The primary goal of the standard was the specification of a simple and robust
WLAN which offers time-bounded and asynchronous services.
