WLAN, short for Wireless Local Area Network, refers to a type of network that allows devices to connect to the internet or share data wirelessly within a specific local area. It is commonly used in homes, offices, and public spaces, providing a convenient wireless network connection to various devices such as smartphones, laptops, tablets, and other Internet of Things (IoT) devices.
In a WLAN, data is transmitted using radio waves instead of traditional wired connections. The network typically consists of a wireless router or access point that acts as a central hub, allowing multiple devices to connect and communicate with each other. WLANs usually operate within a limited range, covering areas such as a room, building, or campus.
WLANs often rely on Wi-Fi technology, which is based on the IEEE 802.11 standard. This standard specifies the protocols and specifications used for WLANs, ensuring compatibility between different devices and manufacturers. It defines the frequencies, security mechanisms, and data transfer rates for wireless communication.
WLANs offer several advantages over wired networks, including mobility, flexibility, and ease of use. Users can connect to the network without the need for physical cables, allowing them to move around freely while maintaining a connection. WLANs also enable convenient sharing of resources, such as printers and files, between connected devices. However, the range of a WLAN is limited, and the signal may experience interference from physical obstacles or other wireless devices. Additionally, WLANs may pose security risks if not properly protected with encryption and authentication mechanisms.
