Precautions for upgrading 5G network jammer

Precautions for upgrading 5G network jammer

  • 2023-01-17
The use of 5G mobile phones is becoming more and more common. If the old network jammer in the exam room does not upgrade to 5G, the 5G signal cannot be shielded during the exam, and it is easy for candidates to cheat using 5G mobile phones. So this requires upgrading the previous machine. What should I pay attention to when upgrading the network jammer to 5G?

① The so-called network jammer upgrade is of course the shielded frequency band of the jammer. The network jammer installed in the school is mainly to prevent the examinees from cheating through various high-tech communication means. In addition to the 2/3/4/5G signal of the mobile phone, signals such as WiFi signal, Bluetooth headset, interphone, etc. need to be shielded. The old network jammer can only shield 234G, not 5G, which requires adding 5G specific frequency band to the original machine to shield 5G.

② Effective shielding distance: for the general examination room, at least one network jammer should be installed in one examination room classroom. This shielding device should be able to block the wireless signal of the whole examination room, and it is better not to interfere with the normal life of the surrounding residents. Therefore, the effective shielding distance should be determined according to the specific conditions of the examination room.

③ The stability of shielding effect must ensure that the whole process of shielding is not intermittent during the test.

Finally, the network jammer operates at a low frequency, so it will not produce noise at all. There is no need to worry about disturbing the examinees who are taking the test. At the same time, its radiation level meets the national safety standards, and it will not cause physical injury to the invigilator and examinees.
