A WLAN consists of these components:

■ Wireless clients are connected to the network (for example, notebooks).

■ Access points build the WLAN infrastructure.

— Autonomous access points

— Lightweight access points

■ Lightweight access points are configured using WLAN controllers.

■ WLAN management is used to administer and monitor large deployments of WLANs.

■ Network infrastructure is provided by switches and routers to connect access points, controllers, management, and servers.

■ Network services such as DHCP; and Domain Name System (DNS); and authentication, authorization, and accounting (AAA) are required for both the wireless network and the user.

■ Cisco Aironet bridges operate at the MAC address layer (data link layer).
