School exams are used to prevent students from using mobile phones to transmit information, leak test papers, and cheat on exams. Some are also to prevent teachers from escorting test papers and leaking test paper information that will adversely affect later exams.

Are all schools suitable for installing mobile phone signal jammers?

The mobile phone signal jammer uses the same frequency as the downlink frequency of the mobile phone receiving base station to carry out the same frequency electromagnetic interference. All of them will be affected by the signal strength of the nearby base station and affect the mobile phone shielding effect. So how to test the mobile phone signal strength in the place where the mobile phone signal jammer is used?

Use a jammer in schools

Midsummer June is about to usher in the high school entrance examination and the college entrance examination. In order to ensure the quality of the examination, many schools have already begun preparations for the examination room early. In the process of preparing for the examination room, there is a very important thing, and that is to install a mobile phone signal jammer. However, not everyone can install cell phone signal jammers. So, what should you pay attention to when installing the mobile phone signal jammer? In fact, the installation itself is still relatively simple, but a few small details before the installation determine the subsequent use of this mobile phone signal jammer. For example, the environment near the installation site. There is also installation height.

In order to ensure the best signal effect, it is generally best to install at least one meter and below three meters. The cell phone signal jammer is relatively small and can be fixed on the ceiling or wall with ordinary screws. Of course, it can also be used directly on top of a table or the like. However, in this case, the effect is not very good. After the installation is complete, check whether all parts are connected properly, and whether there is any problem with accessories such as power supply. Finally, plug the power adapter into the adapter power socket of the machine, and directly connect to the 220V power supply. The next step is to test the machine. If there is a problem, you can contact the manufacturer as soon as possible if you find it during the test process. As long as it is produced by a regular manufacturer, it will usually be resolved in time. If you encounter a pitted manufacturer, it is still recommended to return to the manufacturer directly. So here, we recommend manufacturers like Shenzhen Texin Electronics. Not only the reputation is reliable, but the quality is also reliable. And problems will be solved in time to ensure that the interests of customers are not harmed.
