Wireless LANs in a Campus Network
Wireless LANs (WLAN) transmit and receive data using radio or infrared signals, sent through an access point (AP), and
are not usually required to have radio frequency (RF) licenses. WLANs are local to a building or a campus and are an
extension of the wired network.
Cisco Unified Wireless Network
The Cisco Unified Wireless Network concept has five components that work together to create a complete network, from
client devices to network infrastructure, to network applications. Cisco has equipment appropriate to each component.
Table 9-1 lists components and equipment.
