There is a mysterious figure that has been frequently active in major examination rooms recently. I believe many people do not know its true identity. It is a good helper that has been vigorously promoted in school examinations and can effectively eliminate and prevent cheating. — Exam cell phone signal jammer.
It is almost time for the college entrance examination, and many schools are looking for a batch of higher-performance jammers to ensure stable order in the examination room during the college entrance examination.
But what many people don’t know is that there is one thing that may affect the effectiveness of the jammer. This is an issue that needs to be considered in the examination room. It is the base station, because the appearance of the base station will affect the effect of the exam signal jammer. Of course, this refers to within 500 meters near the exam room.
If it is outside 500 meters, it will not have an impact. As for why it will have an impact, it is Because the base station itself has a strong magnetic field, and the strength of the magnetic field will affect the shielding effect of the examination signal blocker, so when it is put into use in the examination room, you might as well use it first to check the actual shielding range. Then decide how many machines are needed based on this actual data. This must be paid attention to, otherwise some places will not be blocked. However, regardless of whether the test signal jammer will be affected, a machine with superior performance and more professional performance is a must.
