The current mobile jammer shielding technology is relatively mature, and the shielding equipment has a high interference effect, which can cover the communication area within the examination hall, effectively blocking the mobile phone signal inside the examination hall, and ensuring its fairness. The current signal blocking devices have excellent performance, effectively isolating the connection between mobile phones and communication signals. These blocking devices are easy to operate and convenient to use. In addition, the shield also has good stability and reliability, so that it can be used for a long time during exams.

In some particularly important exams, it is necessary to ensure discipline in the exam room. In order to ensure the safety of the exam, more and more examination halls are using mobile jammers to block mobile phone signals inside the examination hall and avoid the impact during the exam process. So far, some shielding devices have become the most ideal choice for the middle school and college entrance exams.
The use of cheating methods in exams can increase the difficulty and pressure of maintaining discipline and order in the exam room. The main means of cheating are the use of these communication devices, which require the existence of different signal blocking devices. I believe this is still very helpful in ensuring a fair environment for exam room order. In complex teaching buildings, it is necessary to fully utilize the function and performance advantages of mobile jammers, so that there is no frequency signal in the examination room, ensuring that mobile phone cheating behavior is completely eradicated.
