Finally, two typical jammings, narrowband jamming and broadband blocking jamming, were designed and added into the system, and then the BER performance of the system was simulated.

With the right device tuned to the right frequency, what's to stop a thief from jamming your setup and blocking that alert signal from ever reaching the base station?

Noise jamming includes blocking, aiming and random pulse jamming, and deception jamming includes transmitting, responding and scattering jamming.
