wireless telegraph
Signals without wires
A wireless telegraph is a communication system that transmits messages using radio waves rather than physical wires.
Developed in the late 19th century, it enabled long-distance communication across oceans and to ships at sea.
The technology preceded voice radio, sending coded signals—typically Morse code—between stations: The ship's wireless telegraph operator sent a distress call.
