With the development of technology, the functions of mobile phones are becoming increasingly diverse. The arrival of mobile phones not only brings convenience to people's daily lives, but also inevitably leads to malicious use of mobile phones to engage in some bad behavior. For example, in the past, cheating in exams was mainly done by taking notes and carrying notes into the exam room, but now it is possible to cheat on your phone. At this point, some equipment is needed to stop these behaviors. Now, the participation of frequency interference machines is indispensable in exams. The use of these interference signals and other devices has solved many cheating phenomena and hidden dangers of disrupting order in the exam room, allowing candidates to take exams in a fair environment. So, it is still necessary to use frequency jammers in some special places.

The main function of the frequency jammer is to interfere with the Mobile phone signal signal and make the mobile phone unable to operate normally. For places such as exam halls, prisons, gas stations, etc. that do not require mobile phones, they are essential equipment. If it is very convenient to use during exams, it only needs to be placed on the podium to interfere with the signals in the exam room, and reasonable use in work will not affect students' exams. In addition, there is no need to worry that such devices will affect the use of other electronic devices. It is mainly used to cut off the connection between the mobile phone and the base station, so as to interfere with the Mobile phone signal signal. At the same time, with the development of technology, the performance of this frequency jammer will become increasingly excellent in the future. Reasonable use in some special places can avoid the problem of signal "random entry", and it is one of the important equipment for interfering with signals.
