Imagine you are participating in a peaceful demonstration that is degenerating and trapped by a mob? You take out the phone to find out where your friend is, and then leave this problematic situation, but you worry that you do n’t have an internet connection. It may be that the police used a cell phone jammer.
A mobile signal jammer is an instrument that protects a mobile phone from received signals. The mobile jammer device sends a signal of the same frequency to a GSM modem. If the signal jammer is activated, after disabling the mobile phone signal at a certain location, it can be said that the interference is successful.
So far, only the military and prisons have access to these devices. From now on, it can also be used by the Federal Police Special Forces and Canine Support Department, the National Security Agency, SEDEE (Explosives Removal and Destruction Service), the Military Intelligence Agency (SGRS), the FPS Foreign Affairs and Home Affairs FPS. What justifies this choice? However, the use of these devices is still strictly regulated because these cellphone jammers interfere with the surrounding network based on their range.
