Recently, many schools are very busy, because the day of the college entrance examination is getting closer and closer, and they are constantly preparing for the materials and machines required by the examination room, so that candidates can take the examination in a stable and orderly environment. This is also the school’s Responsibilities. Therefore, we can see that the wireless signal jammer that many schools have vigorously promoted are installed in the examination room. This is a problem that can effectively counter electronic signal cheating. Although its effect is very good, in actual use, Due to the different installation locations and conditions, the effect is not clear.
Although the size of the shielding range we have seen can be found in the instructions of the test signal shielding attachment, this is a laboratory data for reference only and should be treated differently in actual use. First, whether there is a base station in the vicinity of 500 meters, this is one of the reasons that affect the shielding range, and the impact is different according to the length of the distance. This should be noted. Second, the test signal jammer cannot pass through the wall. Will cause its shielding range to be greatly reduced, and metal objects will also affect its shielding effect. Although these issues will affect the signal shielding effect of the test, it is still a good helper to effectively prevent electronic cheating.
The above are the factors that affect the wireless signal jammer introduced by the editor, and I hope it can be helpful to everyone.
