WLAN - WLANs (Wireless LANs) are local area networks that use wireless

communications for transmitting data. Transmissions are usually in the 2.4

GHz band. WLAN devices do not need to be lined up for communications

like infrared devices. WLAN devices use access points, which are

connected to the wired LAN and provide connectivity to the LAN. The radio

frequency of WLAN devices is strong enough to be transmitted through

non-metal walls and objects, and can cover an area up to a thousand feet.

Laptops and notebooks use wireless LAN PCMCIA cards while PCs use

plug-in cards to access the WLAN.
