radio systems
Wireless transmission networks
Radio systems are networks of equipment that transmit and receive information using radio waves—electromagnetic signals sent through the air rather than through wires.
The term encompasses everything from simple walkie-talkie pairs to complex broadcasting infrastructure, emergency communication networks, and air traffic control.

Radio systems may be one-way (broadcast) or two-way (interactive), analog or digital.
