In the current various types of examinations, the examination room jammer has almost reached complete popularity. It has been used as an important guarantee weapon to maintain the order of the examination room and ensure the fairness and impartiality of the examination. In the process of building a standardized test room, various test supervisory units often ask our manufacturers such a question: In the classroom as the test room, where is the ideal installation position for the test room jammer?

A few years ago, when the jammers in the examination room were only for signal shielding of 2G and 3G signals of mobile phones, some examination rooms did not adopt the method of fixed installation of the jammers, but distributed them uniformly before the exam and unified after the exam. way of recycling. But the consequences of doing so are: the storage and maintenance of the equipment is more troublesome, in the process of distribution and recycling, it is easy to inadvertently damage the equipment, and sometimes it is easy to lose the parts of the equipment. Later, when the 4G and 5G signals became common, the test room jammer went through several iterations, and the size, frequency band, and number of antennas of the equipment increased a lot. If the method of centralized distribution and recycling is adopted, more workload will be added, and the It makes the pre-examination preparations more troublesome, so it has become an inevitable choice to install the test room jammer in the classroom.

The most common installation method is wall-mounted installation, so the question is, a classroom has four walls and a top surface, where is the ideal installation position for the wall-mounted test room jammer?

First of all, the most convenient and reasonable location is the area on both sides and above the blackboard on the front and rear walls of the classroom. Usually, in the area mentioned above, at least one blank space will be found that can be used to install the test room jammer on the wall, and the height after installation is just right, which meets the installation height requirement of 1.8m-2.5m. This can not only meet the requirements of signal coverage, but also prevent students from easily touching the jammer and maliciously damaging the device.

Secondly, the walls on both sides of the classroom in the examination room are relatively centered. When choosing such a location for installation, it is usually because the mobile phone base stations around the examination room are relatively close, resulting in a relatively small shielding radius of the jammer in the examination room. In this way, the radiation characteristics of the omnidirectional antenna of the device can be fully utilized, so as to take into account the overall coverage effect in the classroom of the examination room.

Finally, let’s talk about whether the top of the classroom can also be used as the installation location of the test room jammer. Choosing to install on the top of the classroom and in the center can actually maximize the performance of the jammer, but this choice of location is rather extreme. First, this approach is not beautiful and affects the environment of the classroom. Second, it needs to be considered There may be a beam on the top. When there is a beam, in order to prevent the beam from attenuating the signal of the jammer in the test room, the equipment must be installed at the bottom of the beam.
