How does an FM radio jammer work?

Hence, you can only use the FM radio jammer to block signals from getting to the devices. That said, the jammer works by generating a high-frequency radio signal that confuses the receiver's system from getting the call—regardless of a perfectly working circuit.

Why do FM signals get jammed by digital signals?

Thanks to the FM capture effect, frequency modulated broadcasts may be jammed, unnoticed, by a simple unmodulated carrier. The receiver locks on to the larger carrier signal, and hence will ignore the FM signal that carries the information. Digital signals use complex modulation techniques, such as QPSK.

What is jamming a radio station?

Jamming of foreign radio broadcast stations has often been used in wartime (and during periods of tense international relations) to prevent or deter citizens from listening to broadcasts from enemy countries.

How do you jam a network?

To jam a network, you need to broadcast radio signals on the same frequency, overpowering the original signal. Jamming devices that broadcast on a wide range of frequencies at once can disrupt everything from police radar to GPS systems, and are illegal in many countries.
