radio transmitter
Wireless wave source
A radio transmitter is a device that generates radio waves to send signals through the air.
It converts electrical signals—voice, data, or other information—into electromagnetic waves that propagate to receivers.
Radio transmitters range from massive broadcast towers to the tiny chips in cell phones and wireless earbuds.
The emergency radio transmitter sent out a distress signal.
