Some people say that people should have the right to buy jammers, and VIP people can use these products to prevent illegal pursuits.

Sources familiar with the affairs of the Ministry of the Interior said that these devices have the ability to monitor and interfere with the “drone” manipulation of radio waves. However, there is currently no law to regulate GPS jammers, so it seems that there are many very small jamming devices on the network, which can be used simply by plugging them into a cigar socket.
