Now many universities will build standardized test rooms for CET-4 and CET-6 tests, and jammers are usually one of the necessary equipment for standardized test rooms. So what are the common problems of installing jammers during project construction?

At first, the project construction party thought that installing the jammer was a relatively simple task, thinking that the jamming device could be mounted on the wall and then powered on. As everyone knows, this is only a simple way to deal with it, and often it will not achieve the best interference effect. Especially in some complex on-site situations, it is very likely that the jammer is installed, but the jamming effect is not ideal.

When installing jammers in university classrooms, you first need to consider the choice of installation location. The more common installation locations are on both sides of the blackboard at the front or rear of the classroom, but when choosing a specific fixed location, you also need to pay attention: the antenna of the jammer The area should not be next to audio cables, video cables, etc., otherwise it is likely to cause unnecessary signal interference.

When the jammer is installed in the classroom of the university, you also need to pay attention to the installation height of the jamming device. The recommended installation height is between 1.8 meters and 2.5 meters. If it is installed too low, it will be easily damaged by humans. If it is installed too high, it may cause incomplete coverage and unsatisfactory interference effect.

There are two situations in the university that will seriously affect the effect of the jammer in the standardized examination room. The first situation is: in recent years, many operators' mobile phone base stations have been built directly into the campus, directly installed in teaching buildings or On the roof of other office buildings, the closer the base station is, the more it will affect the interference distance of the jammer. The second situation is: In the corridor of the teaching building, the operator will install indoor signal amplifiers. These indoor signal amplifiers are often installed concealed, such as in the ceiling of the corridor.
