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.
Most modern WLANs are based on IEEE 802.11 standards and are marketed under the Wi-Fi brand name.
Wireless LANs have become popular for use in the home, due to their ease of installation and use. They are also popular in commercial properties that offer wireless access to their employees and customers.
