C H A P T E R Overview Cisco Aironet access points are wireless LAN transceivers that serve as the center point of a stand-alone wireless network or as the connection point between wireless and wired networks. In large installations, wireless users within radio range of an access point can roam throughout a facility while maintaining seamless, uninterrupted access to the network.

Figure 4-1 shows possible levels of security on Cisco Aironet wireless networking equipment, from no security on the left to highest security on the right. The highest level of security, EAP authentication, interacts with a Remote Authentication Dial-In User Service (RADIUS) server on your network to provide authentication service for wireless client devices.
Because WEP (Wired Equivalent Privacy) is the first line of defense against intruders, Cisco recommends that you use full encryption on your wireless network.
WEP key and changes it at the interval you select. Broadcast key rotation is an excellent alternative to TKIP if your wireless LAN supports wireless client devices that are not Cisco devices or that cannot be upgraded to the latest firmware for Cisco client devices. See the “Enabling Broadcast...
