With the continuous development of science and technology, the use of cell phone signal jammers in examination rooms has long become a common device. Moreover, the development of science and technology will produce more powerful signal jammers. The most popular signal jammer in examination rooms at this stage is a kind of signal jammer that looks like a wireless router. It looks like a box. The product quality of this kind of jammer is quite good, but everyone knows, what is the range of an examination room signal jammer? What's the girth? In fact, many people are not clear about this issue.
Generally, the working range of the signal jammer in the examination room is about 10-25 meters. Therefore, judging from the size of the school classroom, one signal jammer for one classroom is generally sufficient. However, you still need to check whether there are signal towers around the examination room. If there is a communication base station that sends signals, in order to prevent some students from fishing in troubled waters, it is best to assemble an additional signal jammer, which is safer. In addition, whether there are walls or columns in the classroom is also particularly important. After all, routers may be blocked by pillars or walls. The height of the classroom also determines the number of signal jammers used in the examination room. A classroom generally has dozens of square meters, and one classroom is fully used. If it is a large-sized stepped classroom used for meetings, it is recommended to prepare more than one.
