radiotelephones
Two-way wireless communicators
Radiotelephones are devices that transmit and receive voice communication via radio waves rather than wires.
The term covers a range of technologies from early ship-to-shore systems to modern cellular phones, though it now sounds dated—most people just say phone or specify the type.
Aircraft cockpits and maritime vessels still use dedicated radiotelephone systems for communication with ground stations.
