Are all schools suitable for installing mobile phone signal jammers?
The cell phone signal jammer uses the same downlink frequency of the mobile phone receiving base station to perform electromagnetic interference at the same frequency. The signal strength of the nearby base station will 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?
The high school entrance examination and the college entrance examination are about to come in midsummer in June. In order to ensure the quality of the examination, many schools have started preparing examination rooms early. In the process of preparing for the examination room, one very important thing is to install a mobile phone signal jammer. However, installing a signal blocker for cell phoneis not something everyone can do. So, what should you pay attention to when installing a mobile phone signal jammer? In fact, the installation itself will be relatively simple, but a few small details before installation determine how effective the subsequent use of the mobile phone signal jammer will be. For example, the environment near the installation site. There is also the installation height.
In order to ensure the best signal effect, topsignaljammer reminds everyone that under normal circumstances, the installation effect is better between one meter and less than two meters. The mobile 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 a table or something like that. However, in this case, the effect is not very good. After installation, check whether everything is well connected and whether there are any problems with accessories such as the power supply. Finally, plug the power adapter into the machine's adapter power socket and connect it directly to the 220V power supply. The next step is to test the machine. If there is a problem and it is discovered during the test run, you can contact the manufacturer as soon as possible. As long as it is produced by a regular manufacturer, it will usually be solved in time. If you encounter a defective manufacturer, it is still recommended to go to the manufacturer directly to return the product.
