The wifi jammer uses the same frequency as the router to receive the downlink frequency of the base station for electromagnetic interference of the same frequency. All the shielding effects will be affected by the signal strength of the nearby base station. So how to test the signal strength of the place where the wifi signal jammer is used?
In school exams, in order to prevent students from using mobile phones to transmit information, leak test papers, and cheat in exams, some also install wifi blockers to prevent teachers from leaking test paper information on the way to escorting test papers, which would have a bad impact on later exams.
In order to ensure the quality of the test, many schools have already started preparing for the test room early. In the process of preparing for the examination room, there is a very important thing, which is to install a wifi bluetooth jammer. However, installing a wifi wireless signal jammer is not for everyone. So, what should I pay attention to when installing the wifi bluetooth jammer? In fact, the installation itself will be relatively simple, but a few small details before the installation determine the subsequent use of the wifi signal jammer. For example, the environment near the installation site and the installation height.
In order to ensure the best effect of the signal, in general, the installation of more than one meter and less than three meters has the best effect. The wireless wifi 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 a table or something. However, in this case, the effect is not very good. After installation, check to see if everything is connected well and if there is any problem with accessories such as the power supply. Finally, plug the power adapter into the adapter power socket of the machine, and directly connect the 220V power supply. Next is the test machine. After the test machine can be used normally, it means that the wifi blocker is in a normal state.
