1. WLAN Introduction of WLAN 802.11b Application

2. WLAN Introduction  What is a Wireless LAN (WLAN)? A wireless LAN is a LAN which accommodates wireless stations. The wireless stations communicate with the wired stations using an intermediary device called an Access Point.

3. WLAN What is IEEE 802.11b?  What is IEEE 802.11b? IEEE 802.11b is a technical specification issued by the Institute of Electrical and Electronic Engineers (IEEE) that defines the operation of 2.4 GHz, 11 Mbps, Direct Sequence Spread Spectrum Wireless Local Area Networks (WLANs).

5. WLAN Definition station (STA): Any device that contains an IEEE 802.11 conformant medium access control (MAC) and physical layer (PHY) interface to the wireless medium (WM). access point (AP):Any entity that has station functionality and provides access to the distribution services, via the wireless medium (WM) for associated stations. basic service area (BSA):The conceptual area within which members of a basic service set (BSS) may communicate. distribution system (DS):A system used to interconnect a set of basic service sets (BSSs) and integrated local area networks (LANs) to create an extended service set (ESS).
