IEEE 802.11 is a wireless LAN technology is based on a cellular architecture where the system is sub divided into cells, Each cell is called Basic Service Set (BSS) is controlled by a base station is called Accesses Point (AP). Access points are connected through Distribution System (DS), typically Ethernet or wireless itself. The important part of the wireless MAC layer design is the security (WEP/RC4 algorithm) implementation. Security protocol is the part of the data link layer.
