The college entrance examination is approaching every year. Facing this most important examination, many schools will actively prepare the things needed by the examination room to ensure the normal order of the examination room and meet the basic needs of the examination room.
In order to deal with the increasingly rampant electronic signal cheating methods, many schools have even purchased wifi jammer for exams as a countermeasure, but their effective scope is limited, so new questions arise. Does the shield still work after passing through the wall?
In fact, we analyze the specific situation of this question. First of all, we need to know what power this test signal jammer is, because it is divided into 12W, 16W and 18W, and the effective range generated by different powers is different. If it is only a small power, it is generally used in a small open area, just enough to meet the size of a classroom.
However, if you want it to pass through the wall, there will be no shielding effect after actually passing through the wall. Therefore, if you choose a low-power wifi signal jammer, try not to pass through the wall. You can equip each teacher with one, and choose a high-power one. One machine can satisfy several classrooms.
Generally speaking, there are still many questions about the purchase of wifi jammers. At this time, you can contact Jammer mart to find out the price. This is a company with a first-class team for technical support and many years of experience in research and development of signal jammers has been highly praised by many customers who have cooperated with it, and it is trustworthy for eliminating the phenomenon of electronic cheating.
