The influence of base stations on the shielding 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.

Now there are less than 100 days left before the college entrance examination. All candidates taking 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 more high-performance cell 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 cell phone signal jammer, that is, the shielding 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 shielding 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 shielding range of the mobile phone signal jammer will be smaller. If the base station is 500 meters away from the examination room, the impact on the mobile phone signal 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 shielding 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 actually test it first to determine the actual shielding range of the jammer, and then decide how manycell phone signal jammers are needed based on the actual test data. This is very important, otherwise some places will not be shielded. However, regardless of whether the cell phone signal jammer will be affected, a more superior and more professional cell phone signal jammer is a must.
