Looking at the news recently, you can find that a device called test signal jammer is frequently appearing in major schools, and you can see them in every test room. What are they? In fact, this is a kind of isolation. The shielding equipment for communication signals is the best way to prepare for the exam and to counter and prevent candidates from cheating with electronic devices in the exam room. This is to allow candidates to take the exam in a fair and authoritative examination room that maintains the normal order of the examination room, so that the candidates' scores are more true and correct.
However, because the shielding effect of the test signal jammer is limited, it is generally within a radius of 0 to 50 meters, and the area is about 250 square meters. Within this range, it can be guaranteed to isolate the communication signal and WIFI signal, but when installing the test signal jammer in the examination room, pay attention to avoid covering it with metal objects, because this will seriously affect its shielding effect, and because the shielding effect will be greatly reduced as the wall penetrates. Fortunately, when using it, it is ensured that it is in an open area, so as to ensure that the effect of the shield is maximized. If you feel that the lower power is not suitable, you can also choose a higher power. In fact, schools have very high requirements for such high-tech equipment and test signal jammers. If you want to choose high-performance equipment, please come to Beijing Shenzhou Mingda to consult the price of signal jammers, which can be provided here. Cost-effective professional equipment, with many years of rich manufacturing experience, quality is guaranteed, welcome to buy and cooperate.
