When can high-power mobile phone signal jammers be used to shield the entire teaching building
Under normal circumstances, it is not recommended to use high-power mobile phone signal jammers to shield the entire teaching building. This is because it is impossible to ensure that the use of high-power mobile phone signal jammers can completely shield the entire teaching building.
However, in some special cases, it is also feasible to use a high-power mobile phone signal jammer to shield the entire teaching building. Shielding the entire examination room can completely achieve the shielding effect. This is because, during the high school entrance examination and the college entrance examination, the relevant departments of the governments at all levels across the country must take joint actions to ensure that these candidates can successfully complete the examination, including the public security, transportation, non-administrative committee, education bureau, examination Some relevant departments or organizations such as hospitals, telecommunications operators, etc., must perform their own duties.
Among them, the public security is responsible for maintaining order, the traffic is responsible for dredging traffic, the non-management committee is responsible for purifying the radio signal environment around the test room, and the communication operator is responsible for reducing or shutting down the signals of all base stations within a few kilometers around the test room. And the mobile phone signal jammer, the size of the shielding range, or the quality of the shielding effect, depends on the strength of the mobile phone signal in the test room.
The communication operator reduces or closes the base station signals within a few kilometers around the test room to reduce the signal strength in the test room to ensure the shielding effect of the mobile phone signal jammer, thereby purifying the radio environment of the test room, and preventing some candidates with bad mentality. to cheat or transmit answers. I believe that everyone will also notice that the operator will send a text message during the middle and high school entrance examination to inform that the mobile phone signal jammer is used in the examination room, and the mobile phone will be disconnected from the network.
