In order to ensure that students can fall asleep immediately after going to bed, so as to ensure that students have sufficient sleep and rest time, the solution is to install and use cell phone signal jammers, which can make students' mobile phones behave as if there is no signal and no network, and it will be effective. Prevent students from hiding under the quilt to play mobile games, chat or watch short videos. So, what are the precautions for installing cell phone signal jammers in student dormitories?

The first thing to note is that cell phone signal jammers are generally installed in the hallway of the dormitory building, not directly inside the student's dormitory. Each cell phone signal jammer is wall-mounted and can usually cover 2-3 student dormitories. Considering that the reinforced concrete material on the floor has a very large attenuation effect on the interference signal, it needs to be installed on each floor of the dormitory building.

The second is the power-on working time of the cell phone signal jammer. Usually, it only needs to be turned on after the lights in the dormitory building are turned off, and it can be turned off after 2-3 hours of continuous power-on, because when students find that there is no signal on the mobile phone, they will naturally not play with their mobile phones for a long time. When 2-3 hours later, all the students have also fallen asleep. If all the cell phone signal jammers are turned on and working, it is not necessary. After the middle of the night, since the purpose of preventing students from abusing their mobile phones has been achieved, put It also saves power consumption when the interfering device is turned off.
