What is a wireless local area network (WLAN)?

A wireless local area network (WLAN) is specifically designed to enable the connection of devices within a limited geographical area, typically a home, office, or campus. This network employs wireless communication technologies, primarily using radio waves, to facilitate the exchange of data between devices such as laptops, smartphones, and printers without requiring physical wired connections.

The use of the term "local area" in WLAN refers to its ability to operate effectively across relatively short distances, often within a few hundred feet, which distinguishes it from wide area networks (WANs) that cover larger geographical areas. WLANs utilize standards like IEEE 802.11 to ensure compatibility and interoperability among various devices, providing flexibility and mobility to users within the network range.

This makes the concept of WLAN crucial for modern connectivity solutions as it allows for more dynamic work environments and enhances user convenience by enabling easy access to the internet and local resources without the constraints of cables.
