wireless local area network (WLAN)



         




wireless local area network (WLAN) is awireless computer network that links two or more devices using a wireless distribution method (often spread-spectrum or OFDM radio) within alimited area such as a home, school, computer laboratory, or office building. This gives users the ability to move around within a local coverage area and still be connected to the network, and can provide a connection to the wider Internet. Most modern WLANs are based on IEEE 802.11standards, marketed under the Wi-Fi brand name.
Wireless LANs have become popular in the home due to ease of installation and use, and in commercial complexes offering wireless access to their customers; often for free. New York City, for instance, has begun a pilot program to provide city workers in all five boroughs of the city with wirelessInternet access.
