The function and application of the signal shield in the examination room

Now there are special test room signal jammers for exams, but some people want to use some means to cheat, and even look for loopholes at all costs. So, what role can the wifi jammer in the examination room play in the examination room? Will there be loopholes in using this device?

The previous signal shielding equipment used segmented cut-off signals, and the signals were converted from time to time. However, this kind of equipment can transmit multiple signals at the same time, the signal is stable, and it can be shielded from a long distance, so don't take chances. Technology is becoming more and more developed now, and many companies are producing more and more advanced products. With the development of science and technology, I believe that the equipment in this area will only become more and more accurate in the future.

The test room signal jammer is an essential tool in the test room to prevent candidates from cheating through scientific and technological means, and escort the information security of the test room. However, if we do not use the signal shielding equipment correctly, the shielding effect will be poor, and an accident in the examination room may occur. In different use sites, the effective shielding range will vary accordingly. This is closely related to the signal field strength at the scene. Mobile phones of different standards may not necessarily have the same shielding range at the same site, so it is very important to detect the local signal frequency band. Factors that can affect the shielding range include but are not limited to: the distance from the base station, the orientation, the presence of obstacles, the wall material of the building on site, and the installation height and installation specifications of the shielding device, preferably in accordance with the manufacturer's requirements.
