The Principle of radio jammers

Radio interference refers to the phenomenon that occurs during radio communication. Some electromagnetic energy enters the receiving system or channel through direct coupling or indirect coupling, resulting in a decrease in the quality of useful received signals, errors or loss of information, and even blocking of communications.

The radio interference signal is mainly the electromagnetic energy that enters the channel or system of the receiving device through direct coupling or indirect coupling. It can affect the reception of the received signal required for radio communication, resulting in performance degradation, quality deterioration, information error or loss, or even blocking The communication was interrupted. Therefore, generally speaking, the fact that useless radio signals cause the reception quality of useful radio signals to degrade or damage is called radio interference.
