What rules should be followed in the design of mobile phone signal jammers in supervision places?
In daily work, we often receive inquiries from dealers and customers. When designing mobile phone signal jammers in supervision places, whether the installation position of the jammer is appropriate is a key consideration, because it will directly affect the final shielding effect. We have summarized several rules to provide customers with reference when designing jammers in supervision places.
1. The building walls of the detention center are generally reinforced concrete, which greatly attenuates wireless signals. The interference signals of mobile phone signal jammers can only enter the room through doors and windows. Therefore, the installation position of the jammer should be as close to the opposite side of the doors and windows as possible;
2. For conventional low-power jammers, in a transparent environment, the effective shielding radius is 10-20 meters. In the prison building of the supervision place, one jammer is arranged at intervals of 2-3 cells. It is best to arrange a mobile phone signal jammer in public toilets, bathrooms, clothes drying areas, etc.; if there is a yard or a ventilation area, a certain number of mobile phone jammers are usually required in these areas;
3. According to the layout of each building in the supervision site, the mobile phone jammers should be deployed in a cellular manner. Although there will be some overlapping coverage areas, this can avoid the generation of shielding signal blind spots to a certain extent;
4. If the outdoor environment of the supervision site also needs signal interference, you can refer to the use of high-power cell phone jammers around the supervision site to shield the main area, and then check the blind spots covered by the signal inside, and then use a few low-power wireless jammers to supplement.
5. When installing high-power mobile phone jammers around the supervision site, it is recommended to install them on the patrol tower or use the fence, street lamp pole, etc. for installation. If it is a wire mesh fence, it is not convenient to install, so you can only take the method of erecting a street lamp pole separately.
