A wireless LAN substitutes radio waves for the fiberoptic or coaxial cables that connect most wire-based LANs. A computer equipped with a wireless modem links to a central computer, called a server, which is also equipped with a modem or modems. Most wireless LAN wireless modems also support direct device-to-device communication separate from the server.

Wireless LANs were originally designed to substitute for wireline LANs; to be used where wires were either too costly to install or where added flexibility (to move computers easily and/or quickly) was needed. For example, many older buildings are difficult to wire for computers (or even phone lines) because of their construction or the presence of hazardous materials such as asbestos. In these cases, wireless LANs may provide a cheaper solution.
