radio transmissions
Wireless broadcast signals
Radio transmissions are signals sent through the air using radio waves—electromagnetic radiation at frequencies used for communication.
The term covers everything from broadcast radio to walkie-talkie exchanges to deep-space signals: We picked up radio transmissions from the downed aircraft.
Unlike wired communication, radio transmissions can be intercepted by anyone with the right equipment.
