A Wireless LAN (WLAN) is a type of Local Area Network (LAN) that uses radio waves to communicate wirelessly between devices. A WLAN allows devices to connect and share data without the need for cables or other wired connections.
WLANs are typically used in home and small office networks, although they can also be used in public spaces such as airports, coffee shops, and libraries. Most modern laptops, smartphones, and other portable devices come with built-in WLAN capabilities.
The architecture of a WLAN consists of three main components: the Access Point (AP), the client device, and the Distribution System (DS). The AP is responsible for transmitting data between clients and the DS. Client devices can be either stationary or mobile. The DS provides connectivity between multiple APs and may also provide Internet access to clients via an integrated modem or router.
