Precautions for upgrading 5G mobile network jammer
The use of 5G mobile phones is becoming more and more popular. If the old mobile network jammer in the examination room has not been upgraded to 5G, the 5G signal cannot be shielded during the examination, and it is easy for candidates to cheat with 5G mobile phones. So it is necessary to upgrade the previous machine. What should we pay attention to when upgrading the mobile network jammer to 5G?
① The so-called jammer upgrade is of course the shielded frequency band of the shield. The mobile network jammer installed in the school is mainly to prevent candidates 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, walkie talkie, etc. need to be shielded. However, the old mobile 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 mobile network jammer should be installed in a classroom of the examination room. This jammer 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 the shielding effect must ensure that the whole process of shielding during the examination can not occur intermittently.
Finally, the mobile network jammer runs in low pitch when it is working, so it will not produce noise at all. There is no need to worry about disturbing the examinee who is taking the exam. At the same time, its radiation level meets the national safety standards, and it will not cause physical harm to the invigilator and the examinee.
