Cut signal in cell phone jammer coverage


As previously seen in other tests, the jammer "covers" the target signal to cut off communication on that frequency. Therefore, the mobile phone jammers studied today will cut mobile phones and GPS within a few meters radius. It will also neutralize the vehicle's GPS plotter. Note that in the technical documentation, it is only expressed as 2G, but as we will see later, it also works on 3G.

Some drone jammers are in the form of boxes, especially when they are omnidirectional (i.e. they compete in all directions), while others (shown above) are designed to be mounted on rifles. Indeed, this is the most natural aiming method. The possibility of equipping a telescope can make the distance captured by the drone greater than the distance that can be seen with the naked eye.

Indeed, the drone jammer shown in the picture above has a range of 300 meters to 500 meters. Therefore, it can be mounted on any type of glasses, and even on virtual glasses (for example, air gun replicas) because the target is not shooting with it.

The principle of a GSM jammers are to generate a sufficiently strong signal to "shatter" signals picked up by the phone within a nearby radius (a few meters), making it inoperable. I have tested several jammers in this article. These jammers are small and lightweight, and some can be placed directly in your pocket.
