The problem of wave jammers in French criminal institutions is frequently in the news. Based on videos of detainees posted on the internet or in the media of elected officials. The issue was raised by the deputy mayor of Brienne-le-Château last week when the National Assembly reviewed the anti-terrorism bill.

Nicolas Dhuicq again urged the interior minister to install jammers in French prisons, especially the central prison, to prevent telephone communications: "We have some recent examples, especially in Clairvaux, of people coming to tinker with modern means of communication", confirms an elected official.

What's really going on inside Auboise's central residence? Before 2016, the agency was equipped with "ineffective" jammers, as was the case in many French prisons, according to a member of the FO coalition.

One event will change everything. In March 2016, barbarian gang leader Youssouf Fofana, who was being held in Clairvaux at the time, posted several videos taken from his cell on the internet.

In the process, a more powerful jammer was installed in the factory: "This created a certain tension. The detainees tried to burn the jammers, making them unusable," noted a Force Ouvrière union member. The detainee's anger led some to say the system appeared to be working: "Of course, agents can still find cell phones, especially in new detainees, but less than before. This shows that the jammers are working. For us, It's an asset. We're still chasing laptops, but it's no longer a priority. I just hope the prison administration will update with new technology in the future," the FO member noted.

In fact, if prisoners can no longer easily transmit information directly over the network, they can always record the video on a chip or USB key and leak the video through the visiting room.
Despite the most sophisticated tools, prisons are never 100% watertight.

Digital Radio Frequency Memory (DRFM): The digital recording of radio signals and retransmission after modification in order to distort information such as position, speed, or distance received by high-power jammers.

One of the practical uses of these systems involves gsm jammers and the uses they can be used for intelligence purposes.

Does every outfit in UK Interceptor need a phone? As British soldiers dealt with all coalition forces in addition to fighting Islamic terrorists in Afghanistan and Iraq, they knew this potential in armed explosions. British authorities are aware that terrorists often use mobile phones because makeshift controllers cause explosions. In light of the August 7, 2005, London bus bombings, criminal enterprises across the country seem to be looking for any excuse for car jammers to engage prisoners in marketing and sales communications that could lead to no breaks for themselves.
