Wireless Local Area NA wireless LAN (WLAN) is a computer network that uses wireless communication to connect two or more devices to form a local area network (LAN) inside a certain area, such as a residence, school, computer lab, campus, or office building. Users can roam across the region while staying connected to the network. A WLAN can also give access to the rest of the Internet through a gateway.

WLANs based on IEEE 802.11 standards are the most widely utilized computer networks on the planet. These are commonly referred to as Wi-Fi, which is a trademark of the Wi-Fi Alliance. They’re often used to link laptop computers, printers, smartphones, Web TVs, and gaming gadgets to the internet through a wireless router in household and small business networks. Consumers can use portable wireless devices to access the internet via hotspots offered by routers in restaurants, coffee shops, hotels, libraries, and airports.
