A WLAN allows users to move around the coverage area, often a home or small office, while maintaining a network connection.
A WLAN is sometimes call a local area wireless network (LAWN).

By the late 1990s, most WLAN solutions and proprietary protocols were replaced by IEEE 802.11 standards in various versions (versions "a" through "n"). WLAN prices also began to decrease significantly.

Wi-Fi is not a technical term, but is described as a superset of the IEEE 802.11 standard and is sometimes used interchangeably with that standard. However, not every Wi-Fi device actually receives Wi-Fi Alliance certification, although Wi-Fi is used by more than 700 million people through about 750,000 Internet connection hot spots.
Every component that connects to a WLAN is considered a station and falls into one of two categories: ac
