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.

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.

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.
