Radio communication requires the use of both transmitting and receiving equipment. The transmitting equipment, which includes a radio transmitter and a transmitting antenna, is installed at the point from which messages are transmitted. Radio is the technology of using radio waves to carry information, such as sound, by systematically modulating properties of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width. The electromagnetic wave is intercepted by a tuned receiving antenna.
