A mysterious figure that has been frequently active in major examination rooms recently. I believe that many people do not know its true face. It is a good helper that has been vigorously promoted in the school's large and small examinations and can effectively prevent and prevent cheating. — Exam jammers.
Whenever the college entrance examination is approaching, many schools are looking for a batch of higher-performance shielding devices to ensure a stable examination room order during the college entrance examination.
But what many people don't know is that there is one thing that may affect the effect of the shield. This is a question 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 test signal jammer. Of course, this refers to within 500 meters of the test room. If it is outside 500 meters, it will not cause any impact. Because the base station itself has a strong magnetic field, and the strength of the magnetic field will affect the shielding effect of the test signal shield, so when it is put into use in the test room, you might as well use it first to see how much the actual shielding range is. Then we need to decide how many machines are needed based on this actual data. This point needs to be taken seriously, otherwise there will be some places that are not blocked. However, no matter whether the test signal blocker will be affected or not, a machine with better performance and more professional is a must have.
