WiFi, which stands for “Wireless Fidelity”, is a label for devices that can receive WLAN and comply with a certified standard. It enables devices, e.g: Computers, smartphones or other electronic devices to connect wirelessly and access the internet.
WiFi uses wireless radio technology so that data can be transmitted over short to medium distances and connections can be established without physical cables. It is based on the IEEE 802.11 standard from the Wi-Fi Alliance (WFA). WiFi is often used as a synonym for WLAN (Wireless Local Area Network), although this equation is not entirely correct. Rather, WLAN is a general umbrella term for wireless local area networks, while WiFi is a specific certification for WLAN technologies.
WiFi offers users the flexibility to move around within a wireless network without being tied to a physical connection. It is an essential part of modern communication and enables wireless access to information and resources on the Internet, as well as the networking of devices in local networks.
