WLAN
A Wireless Local Area Network (WLAN) links two or more devices using some wireless distribution method
 * (Spread spectrum or OFDM radio), and usually providing a connection through an access point to the wider internet.

This gives users the mobility to move around within a local coverage area and still be connected to the network.

Wireless LANs have become popular in the home due to ease of installation, and the increasing popularity of laptop computers.
 * Public businesses such as coffee shops and malls have begun to offer wireless access to their customers; sometimes for free.

Large wireless network projects are being put up in many major cities: New York City, for instance, has begun a pilot program
 * to cover all five boroughs of the city with wireless Internet access.
