A simple way to protect yourself with a portable jammer is to purchase a universal portable telephone shield in our store. The device can mute the radio signal at a sufficiently large distance. They are usually used in public places, conference rooms and leading offices. The GSM signal blocker can be portable or fixed, thus eliminating the cellular communication channel, wireless camera and microphone communication channel.
