WLAN (Wireless Local Area Network)

Wireless Local Area Network is a way of providing a wireless high speed connection between data devices or a data device and an access point over a short range.

WLAN links two or more devices using wireless communication to form a local area network (LAN) within a limited area such as a home, school, computer laboratory, campus, or office building. This gives users the ability to move around within the area and remain connected to the network. Through a gateway, a WLAN can also provide a connection to the wider Internet.
