Wireless LAN (WLAN)

A wireless LAN does not use cable to transmit signals, but rather uses radio or infrared

to transmit packets through the air. Radio Frequency (RF) and infrared are the

commonly used types of wireless transmission. Most wireless LANs use spread

spectrum technology. It offers limited bandwidth, usually under 11Mbps, and users

share the bandwidth with other devices in the spectrum; however, users can operate a

spread spectrum device without licensing from the Federal Co mmunications

Commission (FCC)
