2. Communication that takes place by means of radio waves.
3. An electronic device for receiving sound broadcasts transmitted via radio signals.
4. An electronic device used to send and receive radio signals, used for two-way communication.
5. Sound broadcasts transmitted by means of radio waves.
6. The broadcasting by radio of programs (news, music, talk shows, etc.) for the public.

Telautograph, Tel Autograph
A facsimile telegraph for reproducing writing, pictures, maps, etc.
In the transmitter the motions of the pencil are communicated by levers to two rotary shafts, by which variations in current are produced in two separate circuits.
In the receiver these variations are utilized by electromagnetic devices and levers to move a pen as the pencil moves.

1. Applied to a device which carries out manipulative operations under the control of a person who is not in the immediate vicinity, but who receives feedback from sensors in the device; also applied to a process or system involving such devices.
2. The branch of technology concerned with telechiric devices.
A telautograph or a telegraphic apparatus by which writing or drawing is done with a pen or pencil at the transmitting end and which is reproduced in facsimile at the receiving end, by means of an electric current conveyed along a wire, and (in the usual forms of the instrument) communicating movements to the receiving pen corresponding to those made with the transmitting pen or pencil.
