Recently, we can see that a machine has been installed in the examination room. This is the network jammer vigorously promoted by many schools recently. It is a problem that can effectively counter electronic signal cheating. Although it has obvious effects, it is unknown that when it is actually put into use, the shielding effect will vary depending on the installation location and site conditions, mainly because these places will affect the effect of the network jammer.

Although the size of the shielding range we see can be clearly seen in the description of the network jammer, these data are divided into different situations in practical applications. First of all, the distance from the base station is one of the reasons that affect the shielding range. The impact is different according to the distance from the base station. Secondly, the network jammer cannot go through the wall, which will greatly reduce its shielding effect. In addition, metal objects will also directly affect the shielding effect. Therefore, the shielding range of the network jammer depends not only on the transmission power of each module of the network jammer, but also on the signal field strength of the site base station and the material of the obstacles. Although these problems will affect the effect of the network jammer, it is still the most effective way to eliminate electronic cheating.
