Should you know how to protect yourself from GPS threats

The angle of the GSM jammer antenna can be freely adjusted. Depending on the interference frequency, each stopband can be turned on / off and intensity adjusted. In the United States, blocking radio waves without the permission of the Department of Communications may violate the Radio Law. This method is difficult to achieve where you do not want to use a mobile phone or need a quiet space, and it is difficult to improve only by attracting the audience. However, when I was reading on the train, people around me started to steal my personal mobile phone network, which is very dangerous for the personal information on my mobile phone.
