Will the signal jammer still be effective after passing through the wall? -Mobile phone signal jammer
Nowadays, many schools are busy preparing for the examination. This is because the most important examination of the year, the college entrance examination, is coming soon. Facing this most important exam, many schools are actively preparing to arrange the things needed to arrange the examination room, ensure the normal order of the examination room and meet the basic needs of the examination room. Many of them are also in order to cope with the increasingly rampant electronic technology. As a means of signal cheating, I even purchased an exam signal jammer for cell phone as a countermeasure. However, its effective range is limited, so a new question arises. Will the shielding be effective after it penetrates the wall?
In fact, we analyze this issue in detail. First of all, we need to know what power this exam signal jammer has, because it is divided into 12W, 16W and 18W. The effective range produced by different powers is different. If it is only low power, it is usually used in a small open area, just enough for a classroom. However, if it is to penetrate the wall, there will be no shielding effect after actually penetrating the wall, so if you choose low power The test signal jammer should not penetrate the wall as much as possible. Each teacher can be equipped with one. If you choose a high-power one, one machine can satisfy several classrooms.
