Let's talk about the influence of base stations on the interference effect of cell phone signal jammers from dojammer's blog

Recently, a key device that has been frequently active in major examination halls, 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 of all sizes, which can effectively prevent and prevent candidates from cheating. That is today's protagonist: cell phone signal jammer.

All candidates who take the college entrance examination are concentrating on preparing for the college entrance examination and strive to achieve good results in the college entrance examination. At the same time, many schools are looking for a batch of more high-performance mobile phone signal jammers to ensure a stable order in the examination hall, so that those who use illegal means to cheat have nowhere to hide, thereby improving the fairness of the college entrance examination to 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 jammer, that is, the interference range, which is a problem that all college entrance examination examination halls in the school need to consider. What is this device? It is the operator's base station, commonly known as a signal tower, because if there is a base station near the examination hall, it will affect the interference effect of the mobile phone signal jammer. Of course, this refers to the signal strength of the signal transmitted by the base station to the examination room within 500 meters near the examination room, so the interference range of the mobile phone jammer will be reduced. If the base station is 500 meters away from the examination room, the impact on the mobile phone jammer is very small. As for why it causes an impact, this is because when the base station itself transmits signals to the surrounding area, it will carry a strong electromagnetic signal, and the electromagnetic signal emitted by the base station will decrease accordingly as the distance increases. The strength of the electromagnetic signal field is one of the most important factors affecting the interference effect of the cell phone signal jammer.

Therefore, in terms of the examination room, before purchasing a cell phone signal jammer, it is better to conduct an actual test to determine the actual interference range of the jammer, and then decide how many mobile phone jammers are needed based on the actual test data. This is very important, otherwise some places will not be interfered. However, regardless of whether the mobile phone jammer will be affected, a more superior and more professional mobile phone jammer is a must.
