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 user 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).
