In order to prohibit students from using mobile phones, schools usually use jammers to cheat. For safety and management, prisons can also use gsm jammer to prohibit prisoners, communicate with the outside world and reduce threats to the prison. If used correctly, mobile jammers are definitely beneficial. Regardless of the environment, those who continue to talk over the phone may eventually remain silent. The interference will transmit a high-power signal at the same frequency as the mobile phone, causing the two signals to collide and cancel. This is the basic working principle of any jammer. Simple devices will only block one set of frequencies. 

The US government purchases around 100 poratble drone jammer to protect government facilities, property and personnel. The drone jammer interferes with the drone's radio controls, avoiding dangerous alternatives involving bullets and other projectiles.According to Defensetech, Battelle Labs is selling its DroneDefender handheld drone jammer to the Department of Defense and the Department of Homeland Security. The jammer, which looks like a cross between an old-school TV antenna and an assault rifle, can stop drones over 400 meters away.

If the theater uses jammers and starts the second stage in low light conditions, concert audiences, Broadway fans, moviegoers, and more do not have to worry about this rude behavior.Rotating Faraday’s cage is an extreme behavior that the hat flower shop crowd should try. However, if necessary, you can choose a portable jammer. Of course, there is always an emergency, or there is a doctor on duty, or you must make sure that the caregiver can contact his parents. But these people should find another way to spend the night outside.
