How to install mobile phone signal shielding in school examination rooms, and how to make the shielding effect more perfect
For important exams, classrooms will be installed to block mobile phone signals. There are also many schools that have been installing mobile phone signal blocking in classrooms for a long time for normal exam use. Some schools even turn on mobile phone signal blocking during class. Some dormitories have also installed mobile phone signal blocking equipment in order to stabilize students' work schedules. So how to install mobile phone signal shielding to maximize its effect?
The first situation: For important but temporary use occasions such as college entrance examinations, postgraduate examinations, and CET-4 and CET-6 English exams, due to the relatively short time, for the sake of convenience and flexibility, there is no need for fixed installation to block mobile phone signals. Just bring the shielded mobile phone signal into the exam area and plug it in before the exam starts.
In this case, cell phone signal blockers are usually placed around the podium to facilitate power collection. If the shielding effect is not that good, you can also place the device on a chair or table, with an optimal distance of 1.5-2 meters from the ground. If you only want to place one device in the classroom, but are worried that it will be difficult to shield the area behind the classroom if it is placed at the podium, you can shield the mobile phone signal and place it in the middle of the side of the classroom. At this time, the length of the shield required on both sides of the shield is less, and the effect will be better. Just find the power source.
The second situation: Use the mobile phone signal shielding in the classroom for a long time. This is to block mobile phone signals and need to be fixed at a certain location in the classroom.
The first is to place it higher, 2.5 meters to 3 meters or even higher. In this way, the signal jammer effect is better, on the one hand, it is to avoid human damage. The other is to unify switch management. The blocked mobile phone signals in each classroom need to be connected together, and the use and shutdown are uniformly controlled by the school. They can be turned on and off with one click, avoiding the trouble of turning them on individually in each classroom. In this way, you can choose the online version produced by Nanjing Baikang Electromechanical to block mobile phone signals. This kind of later use is more convenient, but it requires some construction before installation. Compared with the first method, it is simpler and only requires a power supply. However, if there are many examination rooms and classrooms, using the first method will require a lot of manpower and material resources. Schools need to choose between the two methods according to their own needs.
