There is a new dark horse in the examination industry. Can the signal blocker in the examination room really save the current examination chaos?
I don’t know if you have seen such a small advertisement in the bathroom? "Take the exam xxx" or "Helped the exam xxx" similar to this small advertisement. With the emergence of demand in the examination market, such opportunistic tools or equipment have also appeared. However, they are all inseparable from one thing, they need to use mobile phones to send signals. Therefore, some of the corresponding companies have produced some sharp weapons, which is the test room signal jammer. There is a new dark horse in the examination industry. Can the signal blocker in the examination room really save the current examination chaos?
Regarding this issue, in fact, it mainly depends on the quality of the signal jammer used. Good quality signal jammers have better performance and can shield cell phone signals of different frequencies. Including the PHS which has been discontinued. However, most mobile phone signal jammers mainly shield 4G signals. Now that science and technology are developing rapidly, 5G signals are coming soon. If you continue to maintain the previous shielding frequency, then the chaos in the examination room can only be slightly curbed, but it cannot be completely stopped.
