In prisons, detention centers or some criminal detention places, in order to prevent criminal suspects from contacting the outside world through mobile phones, it has become the norm to install jammers. So, what are the general problems in the construction and use of prison cell phone signal jamming projects?

We can consider it from two aspects. The first one needs to be considered: In the prison, which places should focus on cell phone signal interference? Where are you not actually required to install a cell phone signal? In fact, in prisons, it is impossible for prisoners who are serving their sentences to use mobile phones to communicate with the outside world in public places and crowded places. Therefore, such places are not places that need to focus on installing jammers. Such places generally include: activity centers, classrooms, operations, open squares, etc.

The places where prisoners serving sentences in prisons may use mobile phones are the places where jammers must be installed. Such places include: toilets, clothes drying rooms, warehouses, tool rooms, etc. These are relatively hidden places, which are convenient for When a person handles private activities, it is of course convenient to use the mobile phone to communicate with others.

From the above sub-board, you can know that in a prison, blindly propose to install jammers all over the entire prison, hoping that this can achieve the effect of overall signal interference, which is actually somewhat unrealistic, although The intent is good, but it certainly adds to the project budget and construction and management costs for the jammer project. Our proposition, however, is that jammers only need to be installed in key areas of the prison where cell phones are ensured, effectively cutting off prisoners from the outside world.
