The Ministry of Education of the People’s Republic of China issued a report on cheating in the college entrance examination. The content of the report was that an examinee in Hubei province took the exam questions with his mobile phone and uploaded it to Xiaoyuansou for answers, and was reported by Xiaoyuansou. After verification, the examinee did indeed cheat. At present, all the results of the examinee have been cancelled, and the invigilators involved are also investigated by the disciplinary inspection and supervision organs.
Seeing this, many netizens were shocked! Let’s not talk about how this examinee brought his mobile phone into the examination room through heavy security checks. Even after entering the examination room, every examination room will have a mobile cell phone signal jammer. Why does this examinee’s mobile phone still have a signal in the examination room?
As we all know, in order to ensure the fairness of examinations, various education bureaus will adopt various anti-cheating measures in the college entrance examination examination room. In addition to the most common metal detectors, signal jammers are used. The coverage of mobile phone jammers is extremely wide. There is no signal. However, 5G mobile phones are popular on the market this year, and the cheating candidates used 5G mobile phones.
At present, the recruitment staff of Huangpi District, Wuhan, Hubei also responded, saying that the cheating candidates used 5G signals. It is estimated that there was a loophole when the mobile phone jammer in the exam room blocked the 5G signal, which caused the candidate to upload the exam questions to the small Ape search questions. Or, the shielding device has not been shielded for a while, but everyone is more accepting that the 5G signal has loopholes.
Next, I will show you the difference between 4G network and 5G network in popular science. The frequency spectrum of 4G is generally between 1700MHz and 2600MHz, while the frequency spectrum of 5G will be as high as 4960MHz, and the network speed will be faster if the frequency spectrum is high. . The signal jammer in the examination room ignores the frequency band of the 5G mobile phone and still uses the previous mobile phone signal jammer, which will cause loopholes.
