With WLAN it is possible to exchange data within a network, but the main use is to connect to the Internet. Before a connection to a network, usually a router, can be established, WLAN must be switched on.

Note: On Samsung devices, WLAN can be switched on/off using the settings and the quick settings in the status bar.
