Nowadays, although the rapid development of wireless communication greatly facilitates people's life all over the world, it is also abused by criminals, which has seriously endangered people's life safety and law enforcement justice. In prisons, inmates can use mobile phones to direct outside associates from their restricted cells to continue illegal activities. Behind the scenes, they plan to exonerate, command silence, and even contact outside accomplices to carry out prison riots and escape. The perfect solution to this problem already exists -- a high-powered cell phone jammer designed for prisons and larger Settings. High-power mobile phone signal shielding device can completely eliminate the possibility of prison inmates using mobile phones to communicate.
