The annual postgraduate entrance examination has ended successfully, and the news about the deployment of a wifi jammer system in the postgraduate entrance examination center has become a big hot spot. Since the production of this device, it has only been used in the college entrance examination examination room. It can be seen that the country will be more stringent in detecting cheating in examinations.
Nowadays, whether it is for the postgraduate entrance examination or the college entrance examination, cheating can be said to be varied. And cheating tools are becoming more and more advanced. Judging from the data of the past two years, cheaters have abandoned their mobile phones to cheat because every examinee will be detected by WiFi jammers. The current method of cheating is to transmit data via radio. As long as the cheaters adjust the acceptance frequency outside the examination room and wear a miniature earphone, they can receive and hear the answers sent outside through the data in the examination room. Therefore, in order to prevent the repeated occurrence of such cheating, the WiFi signal jammer system adopted by the postgraduate entrance examination is undoubtedly a good blow. The device can cut off all the radio signal transmission around the examination room, so that cheaters have nothing to cheat.
