Now many universities will build standardized test rooms for English CET-4 and CET-6, and test room signal jammers are usually one of the necessary safeguards for standardized test rooms. So what are the common problems in installing test room signal jammers during the project construction process?
At first, the project construction party thought that installing the signal jammer in the examination room was a relatively simple job, thinking that it would be enough to hang the shielding device on the wall and then turn it on. As everyone knows, this is just a simple way to deal with it, and it often does not achieve the best shielding effect. Especially in some complicated on-site situations, it is very likely that the signal jammer in the examination room is installed, but the shielding effect is not ideal.
To install the test room signal jammer in the classroom of the university, you first need to consider the choice of installation location. The more common installation location is on both sides of the blackboard at the front or rear of the classroom, but when choosing a specific fixed location, you need to pay attention to: the test room signal The antenna area of the jammer cannot be close to audio cables, video cables, etc., otherwise unnecessary signal interference may occur.
The signal jammer in the examination room is installed in the classroom of the university. It is also necessary to pay attention to the installation height of the shielding equipment. The recommended installation height is between 1.8 meters and 2.5 meters. If the installation is too low, it is easy to be damaged by man. If the installation is too high, there may be incomplete coverage and unsatisfactory shielding effect.
There are two other situations in the university that will seriously affect the effect of the test room signal jammer in the standardized examination room. The first situation is: in recent years, many mobile phone base stations of operators have been directly built on the campus and installed directly in the teaching area. The closer the base station is to the roof of the building or other office buildings, the more it will affect the shielding distance of the signal jammer in the examination room. The second situation is: in the corridor of the teaching building, the operator will install indoor signal amplifiers, and these indoor signal amplifiers are often installed concealedly, such as installed in the ceiling of the corridor.
