The annual exam season is coming. The college entrance examination in June and the high school entrance examination in July are often concerned by many people. Different people have different focus of attention. Let's talk about a content that is hardly paid attention to by the public: what role does the frequency jammer play in the guarantee work of the examination room? Why do some people say: frequency interference will come in handy every exam season?

When the school prepares for the examination season, it will construct standardized examination rooms in accordance with relevant standards and requirements. These standardized examination rooms are generally selected from conventional classrooms. In recent years, frequency jammers have been installed in these standardized examination rooms almost as a standard configuration.

At that stage about ten years ago, the application of frequency jammers in standardized examination rooms was not popular, and usually they were not installed in a fixed way. Only on the day of the exam, the frequency jammers were temporarily distributed to classrooms in each examination room. , when the exam is over, the frequency jammers will be recovered in a unified way. This actually brings a lot of extra work to the organizers and administrators of the exam. Moreover, in the process of distribution and recycling, it also increases the possibility of man-made damage to equipment.

In recent years, the vast majority of standardized examination rooms have adopted a fixed installation method. The frequency interference meter is installed in a certain corner of the classroom. Even if it is not used very often, it will not affect the normal daily teaching use of the classroom. . Some schools will even purchase some intelligent, network-based frequency jammers. Through the campus network, the frequency jammers in all test classrooms will be networked together, and then functions such as remote centralized control and management can be realized, which will greatly save manpower and improved management.

When the exam season comes, the competent department of the exam can effectively prevent those who want to use modern electronic communication equipment to cheat in the exam with the help of the working characteristics of the frequency jammer.
