Radio Communication Technology
Radio communication technology is the use of radio waves to carry and convey information primarily sound by controlling electromagnetic waves which are sent through space. The radio waves work by hitting an electrical conductor which causes the wavering fields to prompt an alternating current in the electrical conductor.
The information transmitted in the oscillations the baseline of radio communication. For the electric currents to be converted into the radio waves an antenna is required and can be used to serve both the receiving and transmission purposes. Radio stations are selected and determined by the electrical character transmitted in the tuned circuits. The input from the antenna is received by the radio receiver and converted into sound. Radio stations are classified according to the frequencies on which they air. These frequencies are normal between 3 kHz to 300 GHz.
In the communication channel, a receiver and transmitter are included in the radio equipment. A microphone is used in conveying the information and a loudspeaker used at the receiving end.
