In recent years, with the rapid development of mobile phones, it is not uncommon for students to use mobile phones to affect their life and study. Many teachers who inspected the school dormitory at night said that they often found that some students were using mobile phones to surf the Internet in the bed, and some even until midnight. It is still up at two o'clock, so in order to prevent students from playing mobile phones in the middle of the night and let them rest better, many schools have to choose to install cell phone signal blocker in dormitory buildings.
The mobile phone signal jammer in the dormitory does not need to be turned on 24 hours a day, so the jammer with ordinary power supply such as an external adapter can also be selected. During installation, you can choose to have a timer switch to set the time to work. Once set, the shielding device can be automatically turned on when it needs to work without manual control.
In general, a small mobile phone signal jammer is used, which is usually placed under the monitoring wall of the corridor outside the dormitory. Since the signal will be attenuated through the wall, try to choose a device with higher power and grasp its shielding distance. Then you have to put one at a certain distance, on every floor, and let the signals of these mobile phone jammers form a network, which is much better than using a single jammer alone. In the final installation, use all jammers with A power cord is connected, a main switch is connected, and it can be controlled together when using, so it is very convenient to use.
