# Wi-Fi (General)

Wi-Fi is a wireless networking technology used for wireless local area networks also called WLAN.
It allows devices to communicate over radio frequencies without physical cables.
It needs a module or adapter and therefore relies on dedicated
[hardware](/wiki/hardware_%28general%29.md).

Informations on Wi-Fi usage on [Linux](/wiki/linux.md)-based operating systems are described in
the [Wi-Fi section of the Linux hardware entry](/wiki/linux/hardware_%28linux%29.md#wi-fi).
