It is a key device that has been frequently used in major examination rooms recently. I believe many people should know the real role of this device. It is a key device that has been vigorously promoted in school exams and can effectively prevent and prevent candidates from cheating. , that is today's protagonist: cell phone signal blocker.

There are less than 100 days left for the college entrance examination. All the candidates who take the college entrance examination are concentrating on preparing for the college entrance examination and striving to achieve good results in the college entrance examination. At the same time, many schools are looking for a batch of higher-performance mobile phone signal jammers to ensure a stable examination room order, so that those who use illegal means to cheat have nowhere to hide, thereby improving the fairness of the college entrance examination for each candidate.

But what many people don't know is that there is such a device, which may have a serious impact on the effect of the mobile phone signal shielding device, that is to say, the shielding range. This is a problem that needs to be considered in all college entrance examination rooms in schools. What is this device? It is the base station of the operator, commonly known as the signal tower, because if there is a base station near the examination room, it will affect the shielding effect of the mobile phone signal jammer. Of course, this means that within 500 meters of the test room, the signal strength of the signal transmitted by the base station to the test room will be very strong, so the shielding range of the mobile phone signal shielding device will become smaller. If the base station is 500 meters away from the test room, the impact on the mobile phone signal shielding device is very small. As for why it has an impact, this is because the base station itself will have a strong electromagnetic signal when it transmits signals to the surrounding area, and the electromagnetic signal emitted by the base station, as the distance increases, the field strength of the electromagnetic signal will also correspond. The strength of the electromagnetic signal is one of the most important factors affecting the shielding effect of the mobile phone signal jammer.

Therefore, in the examination room, before purchasing a mobile phone signal blocker, you may wish to actually test it to determine the actual shielding range of the blocker, and then decide how many mobile phone signal blockers you need based on the actual test data. This is very important, otherwise there will be some places that are not blocked. However, no matter whether the cell phone signal jammer will be affected or not, a more superior and more professional cell phone jammer is a must-have.
