Where is the ideal installation location for the wireless jammer in the examination room?
In the current various types of examinations, the wireless jammer in the examination room has almost reached complete popularization. It has become an important guarantee for maintaining the order of the examination room and ensuring the fairness and justice of the examination. In the process of building standardized examination rooms, various examination authorities often ask our manufacturers such a question: In the classroom as the examination room, where is the ideal installation location for the wireless blocker in the examination room?
A few years ago, when the wireless jammer in the examination room was only used to block the 2G and 3G signals of mobile phones, some examination rooms did not adopt the method of fixed installation of the jammer, but adopted the method of unified distribution before the examination and unified collection after the examination. However, the consequence of doing so is that it is more troublesome to keep and maintain the equipment. In the process of distribution and collection, it is easy to cause inadvertent damage to the equipment, and sometimes it is easy to lose the parts of the equipment. Later, when 4G and 5G signals became common, the size, frequency band, and number of antennas of the wireless jammers in the examination room increased a lot after several iterations. If the centralized distribution and recycling method is adopted, it will increase the workload and make the preparation work before the exam more complicated. Therefore, it is inevitable to install the wireless jammers in the classroom.
The most common installation method is wall-mounted installation. Then the question is, a classroom has four walls and a top surface. Where should the ideal installation position of the wall-mounted wireless jammer be?
First of all, the most convenient and reasonable position is the area on both sides and above the blackboard on the front and back walls of the classroom. Because in this area, at least a relatively empty position can be found to be used for wall-mounted wireless jammers in the examination room, and the height after installation is just right, meeting the installation height requirements of 1.8 meters to 2.5 meters. This can meet the requirements of signal coverage and prevent students from touching the jammer too easily and maliciously damaging the equipment.
Secondly, the walls on both sides of the examination room classroom are relatively centered. When choosing such a location for installation, it is usually because the distance between the mobile phone base stations around the examination room is relatively close, resulting in a small shielding radius of the examination room wireless jammer. This installation location can be fully utilized to fully utilize the transmission characteristics of the omnidirectional antenna of the equipment, thereby taking into account the overall coverage effect in the examination room classroom.
Finally, let's talk about whether the top of the classroom can also be used as the installation location of the examination room wireless jammer. Choosing to install it on the top of the classroom and in the center can actually maximize the performance of the jammer, but this location selection is relatively extreme. First, this approach is not beautiful and affects the atmosphere of the classroom. Second, it is necessary to consider the possibility of a beam on the top. When there is a beam, in order to prevent the beam from attenuating the signal of the examination room wireless jammer, the device must be installed at the bottom of the beam.
