I'm a prison worker. As drones have become more sophisticated recently, many have used them to transport contraband to prisons. I know of a drone jamming device that can handle this. But I don't know that it's legal in the United States or not
With the development of drone technology, people have more knowledge and application of drone. But not everyone is using the technology for good. As you said, many criminals use this kind of equipment to smuggle contraband. And the drone jammer gun is the best way to solve this problem.
The federal central prison has now applied to try the device.
