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 Communications Commission (FCC).
