nmcli radio [switch] [on|off]

nmcli radio controls the software radio switches for wireless interfaces managed by NetworkManager. This is equivalent to airplane mode functionality, allowing Wi-Fi and mobile broadband radios to be enabled or disabled independently.
Disabling a radio switch turns off the corresponding hardware transmitter, preventing any wireless communication. This is different from just disconnecting—the radio itself is turned off.
Without an on/off argument, the command displays the current state of the specified radio(s).

Software radio control depends on hardware and driver support. Some laptops have physical radio switches that override software control. Enabling the radio doesn't automatically connect to networks; it just makes the hardware available for connections.
