Midsummer June is about to usher in the high school entrance examination and college entrance examination. In order to ensure the quality of the examination, many schools have already started preparing for the examination room in advance. In the process of preparing for the examination room, there is a very important thing, that is to install a mobile cell phone jammer. However, installing a cell phone signal jammer is not for everyone. So, what should I pay attention to when installing the mobile phone signal jammer? In fact, the installation itself will be relatively simple, but a few small details before the installation determine the subsequent use of the mobile phone signal jammer. For example, the environment near the installation site. And the installation height.
Now many schools are busy preparing for the examination room. This is because the most important examination of the year, the college entrance examination is coming soon. Facing this most important exam, many schools are actively preparing what is needed in the exam room, ensuring the normal order of the exam room and meeting the basic needs of the exam room. As a means of signal cheating, the test signal jammer was purchased as a countermeasure, but its effective range is limited, so a new question arises, is it still effective after it penetrates the wall?
