Can a high-power mobile phone signal jammer be used to shield the entire teaching building?
Under normal circumstances, it is not recommended to use a high-power cell phone signal jammer to shield the entire teaching building. This is because it is impossible to ensure that the use of a high-power mobile phone signal blocker can completely shield the entire teaching building, even if a high-power mobile phone is used. A signal shielding device is used to shield the entire teaching building, and there are also some areas where mobile phone signals cannot be shielded.
However, in some specific cases, using a high-power mobile phone signal blocker to shield the entire teaching building can also achieve the shielding effect. The signal shielding device to shield 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 Relevant departments or organizations such as hospitals, communication operators, etc., must perform their respective duties to ensure the smooth and successful conclusion of the high school entrance examination.
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 the signal strength of all base stations within a few kilometers around the test room or choosing to directly shut down the base station. The size of the shielding range of the mobile phone signal shielding device, or the quality of the shielding effect, depends on the strength of the mobile phone signal in the test room.
The purpose of reducing or shutting down base station signals within a few kilometers of the test room is to reduce the signal strength in the test room to ensure the shielding effect of the mobile phone signal jammer, so as to purify the radio environment of the test room and prevent some unhealthy candidates. radio to cheat or transmit answers. I believe that everyone will also notice that the operator will send a text message during the high school and college entrance examination to inform that the mobile phone signal shielding device is used in the test room, and the mobile phone will be disconnected from the network at that time.
