Wireless Local Area Networks (WLAN) have become very popular because they are very easy to setup
and use, and have low maintenance costs. Generally, several access points (APs) can cover a building
or an area. A WLAN is not completely wireless because the servers in the backbone are fixed.
The WLAN solution allows you to provide the following wireless LAN services to your customers:
Connectivity to conventional networks or the Internet
WLAN client connectivity to conventional 802.3 LANs
Secured WLAN access with different authentication and encryption methods
Seamless roaming of WLAN clients in a mobility domain

Access controller (AC)
An AC can control and manage APs associated with it in a WLAN. The AC communicates with an
