Before each year’s postgraduate exams, students will successively receive some information about cheating in the exams. In fact, these cheating methods are carried out by radio, and candidates are required to carry special earphones to receive answers from outsiders. There have been frequent occurrences of cheating through radio, but since the radio frequency monitoring and blocking system was in place, many candidates’ dreams have been disillusioned. Through radio frequency monitoring and blocking the use of the system, no high-tech tool can cheat. Compared with the mobile cell phone jammer, this device has more comprehensive functions, because it can not only cut off the communication data signal, but also can shield the radio signal to prevent any form of data transmission.
Cheating in all exams is shameful. Therefore, candidates should stop imagining the dream of cheating. Instead of thinking about how to cheat, it is better to calm down and read the book. If you want to use a mobile phone jammer, it means that we want to make this exam more formal, and we also hope that everything is more assured. I am also paying attention to how to block the signal in the exam. Everyone must have a correct attitude. In this process, the teacher must really do a good job of management to ensure that the signal is completely shielded and there will be no errors. No matter what we do, we should adhere to certain principles. When you can uphold your own principles and complete these aspects of work, then you will be better for yourself.
