A wireless local area network (WLAN) refers to a computer network that enables devices to connect and communicate wirelessly within a limited geographical area. It is commonly used in homes, offices, schools, and other public spaces to facilitate the exchange of data and information between devices.
A WLAN typically consists of multiple devices, such as computers, smartphones, tablets, printers, and access points, which establish wireless connections through radio waves. These connections allow for seamless communication between devices without the need for physical wires or cables.
The network infrastructure of a WLAN consists of access points (APs) that serve as the central hub for connecting devices. These access points act as transceivers that transmit and receive data signals between wireless devices and connect them to the wired network if required. They facilitate wireless connectivity by converting the data into radio waves and transmitting them over specific frequency bands.
To establish a connection, devices equipped with wireless network adapters can search for available WLANs and connect to them using a unique network name and password called the Service Set Identifier (SSID). Once connected, devices on the WLAN can share resources, access the internet, and communicate with each other.
WLANs offer numerous advantages, including flexibility, mobility, and convenience, as they eliminate the need for physical cables and allow users to move freely within the network coverage area. However, the range of a WLAN is limited, typically ranging from a few tens to a few hundred meters, depending on several factors such as signal strength and environmental obstructions.
