During the college entrance examination season, the school designated as the examination site will be busy preparing for the examination room in advance. In the face of this most important examination, many schools designated as examination sites are actively preparing to arrange the relevant equipment required by the examination room to ensure that the equipment and systems required by the examination room meet the basic needs of the examination room. In order to cope with the increasingly rampant use of new types of cheating devices, the mobile phone signal jammer, as an important part of anti cheating devices, is also essential. We all know that the mobile phone signal jammer plays an important role in the college entrance examination, and its interference range is also limited, so a new question arises. How effective is it in penetrating the wall?

In fact, we need to analyze this problem in detail. First of all, we need to know what the transmission power of this mobile phone jammer is. The interference range generated by different powers is different. If it is just a small power mobile phone signal jammer, it is generally aimed at using it in a relatively open small range indoors. In school classrooms, this kind of use environment is just right to meet, However, if you want the jammer to penetrate the wall and still have a good shielding effect on the mobile phone signal, it may not be realistic. As we all know, the shielding of the wall will lead to the attenuation of most interference signals after the shielding signal penetrates the wall. Therefore, if you choose low-power jamming equipment, try not to consider using it through the wall. It is better to equip each classroom with a small power cell phone signal jammer. If you choose a high-power mobile phone signal jammer, you should first consider the cost, and also consider the noise generated by the device, which will more or less affect the sending back of some candidates in the examination room, thus affecting the test results. This is the result that everyone does not want to see, and it is also a responsibility that no one can bear.
