Recently frequently active in the major examinations of a mysterious figure, I believe that many people do not know its true nature, it is a kind of school has been vigorously promoted in the size of the examination, can effectively eliminate and prevent the phenomenon of cheating good helper - wifi jammer.
Now it is almost time for the examination season, many schools are seeking a number of more high-performance wifi jammer, in order to protect the stability of the examination room order.
But what many people do not know is that there is one thing, it may have an effect on the shield effect, which is the exam room side are required to think about. It is the base station, because the appearance of the base station will affect the effect of the test signal shields, of course, this refers to the 500 meters in the vicinity of the examination room, if it is outside the 500 will not cause the impact, as to why it will cause the impact, because the base station itself with a strong magnetic field, and the strength of the magnetic field will affect the shielding effect of the test signal shields.
