What should I pay attention to when upgrading the 5G shielding device at the test center?
The date of the college entrance examination is getting closer, and many college entrance examination centers are stepping up the work of upgrading and transforming 5G shielding devices, because the use of 5G mobile phones is so common now, if the 5G signal cannot be shielded during the test, it is easy for candidates to use 5G. Mobile phone cheating. What should be paid attention to when the test center upgrades and transforms the 5G jammer device?
The first point is of course the blocking frequency of the shielding device. The shielding device installed at the test center is mainly to prevent candidates from cheating through various high-tech communication means. Signals such as walkie-talkies and conductive headphones must be shielded.
The second point is the effective shielding distance. For the standardized test room, at least one shielding device should be installed in one classroom of the test room. This shielding device needs to be able to block the wireless signal of the entire test room, so the effective shielding distance should be more than 10 meters. . And it is best to disturb the normal life of the surrounding residents, so the effective shielding distance depends on the specific situation of the examination room.
The third is the stability of the shielding effect. It must be ensured that the whole process of the test is shielded, and there can be no intermittent situations.
Then it is best not to disturb the candidates who are taking the exam when the shielding device is working, which requires the shielding device to be quiet and low-noise when working, or even no noise at all. At the same time, it is also required that the radiation level of the shielding device meets the safety standards required by the state, and will not cause physical damage to the invigilator and candidates.
MDPB-X12 full-function mobile phone signal blocker is the latest high-tech shielding product specially designed by Shenzhou Mingda for the examination room, which can effectively shield (interfere) all mobile phone signals (CDMA, GSM, DCS, PHS, 3G, 4G, 5G) in the examination room. ) and 2.4G/5.8G WIFI(WLAN), Bluetooth/2.4G communication, wireless network (QQ and Weibo, etc.), pinhole camera signal.
