A necessary tool for "cheating prevention" in the examination room -- signal jammer

A necessary tool for "cheating prevention" in the examination room -- signal jammer

  • 2022-10-23

Some people want to use some means to practice favoritism and malpractice in the examination room, and even bring their mobile phones to the examination room at all costs. With the current interference technology, some instruments that interfere with signals have become reliable equipment in the examination. Now, the signal jammer plays an important role in the examination room, purifying the examination room and eliminating the phenomenon of signal rejection cheating.

The previous signal jammers used segmented cut-off signals, which were converted one after another. After many updates, the current signal jammer can transmit multiple signals at the same time. The signal is stable and can interfere at a long distance. Therefore, don't take chances in the examination certificate. Now the technology is more and more developed, and the products produced by many companies are more and more advanced. With the development of science and technology, I believe that the equipment in this field will become more and more accurate in the future.

Signal jammer is a necessary tool to prevent examinees from cheating in the examination room through scientific and technological means, and it protects the safety of information in the examination room. However, if it is not used correctly, the interference effect may be poor, and there may be interference accidents and signal leakage in the examination room. In different use sites, the effective interference range will be different. This is closely related to the signal field strength on site. The interference range of different mobile phones in the same site is not necessarily the same, so it is very important to detect the local signal frequency band. The factors that can affect the interference range include but are not limited to: the distance from the base station, the orientation, whether there are obstacles, the wall material of the site building, and the installation height and installation specifications of the jammer. Therefore, it is recommended to follow the manufacturer's requirements in terms of installation and use.
