I believe that for many students, they should have seen in the school recently that a kind of mysterious equipment has been installed in the classroom, and they are all wondering what effect it has. In fact, this is exactly what is called test signal shielding. Today’s device has been widely used for examinations in major schools, especially the college entrance examination which is about to arrive recently. The major examination halls have accumulated enough energy to provide candidates with examination rooms before the arrival of the college entrance examination. The most advanced method to ensure the order and stability of the examination room is to prevent cheating.
For the test signal jammer, there are several characteristics. First of all, its battery life is relatively short. The main reason is that the general test time is not too long, so it does not need too long working life. The reason for this It can make the heat dissipation capacity worse, the product price will be lower, because the general examination room must be equipped with a lot of test signal jammers, and they generally have a limited budget, so the more cost-effective machines and equipment can be more affected by them. Favor, and this kind of machinery and equipment not only satisfies the price but also the powerful shielding effect, and plays a powerful role in the stability and order of the examination room. To prevent cheating in the examination room, it is undoubtedly a need for a professional test signal jammer. Among them, Beijing Shenzhou Mingda is a manufacturer that can provide high-performance and affordable test signal jammers, and its advantages of high quality and low price have won The favored choice of many schools has now appeared in the examination rooms of major schools, providing a strong guarantee for preventing electronic signal cheating.
