So recently we can see that a kind of machine has been installed in the examination room. This is the wifi jammer that many schools have vigorously promoted recently. It is a device that can effectively counteract the problem of electronic signal cheating, although it is an It is so effective, what is unknown is that when it is actually put into use, its effect is also different according to the installation place and situation.
Although the size of the shielding range we have seen can be found in the instruction manual that comes with the wifi signal jammer, this data is laboratory data and is for reference only, and the actual use depends on different situations. First of all, there is no base station within 500 meters of the vicinity, this is one of the reasons that affect the shielding range, and the impact is different according to the length of the distance. It should be noted that secondly, the wifi signal blocker cannot pass through the wall. This will cause its shielding effect to drop significantly, and metal objects will also affect its shielding effect. Although these kinds of problems will affect the effect of the test signal jammer, it is still the most effective helper to eliminate electronic cheating.
