The examination hall is a sacred and solemn place, but there are always people who maliciously use illegal methods in the examination, which will increase the difficulty and pressure of maintaining discipline and order in the examination hall. The main means of cheating is the use of communication equipment, which requires the presence of different signal blocking devices. I believe this is still very helpful in ensuring a fair environment of order in the examination hall. In complex teaching buildings, the role and performance advantages of signal jammers are fully utilized to ensure that various behaviors of mobile phone cheating can be completely eradicated.

If faced with some complex on-site environments, relying on current signal shielding technology, it is particularly important to have a deep understanding of the role of signal jammers. The shielding effect of different specifications of shielding equipment is definitely different. Only by ensuring that the overall strength of the equipment application is gradually strengthened can the shielding effect be comprehensively improved under the same conditions. The main reason is that the more complex the working environment of current signal jammers is, they are not only used in classrooms, but also have more stringent equipment performance requirements. After different shielding requirements are met, this is also a direct reflection of the performance advantages of shielding equipment, and can also have excellent performance under harsh working conditions. The current signal blocking technology has been used in various places, and so far the technology is quite mature, which can capture signals in various complex scenarios.
