In recent years, with the rapid development of mobile phones, it is not uncommon for students to use mobile phones to affect their lives and studies. Many teachers who inspect the dormitory at night said that they often find some students use their mobile phones to go online in the bed, some even in the middle of the night. It is still at one or two o'clock, so in order to prevent students from playing with their mobile phones in the middle of the night, so that they can have a better rest, many schools have to choose to install mobile phone signal jammers in their dormitories.
So is it enough to put a cell phone jammer in each room in the school dormitory like the school examination room? Actually, how to choose and install is explained below. The cell phone signal jammers installed in school dormitories are mainly used at noon and evening when students are resting. Noon is usually 11:30 to 1:30, and at night is 10:30. Until 2 o'clock in the morning. That is to say, it is not required that the mobile phone signal is shielded for 24 hours without interruption, so the shielding device of the ordinary power supply such as the external adapter is also optional.
When installing, it is recommended to connect a timer switch to set the working time. When the time comes, no manual control is required, and the mobile phone signal jammer can be automatically turned on when it needs to work. Effective segmentation, only interferes with the downward installation height: 1.0-2.0 meters is the best effect, low energy consumption, energy saving and environmental protection, while not posing a threat to the health of students and staff. How to choose a jammer suitable for dormitory use. When the jammer is turned on, the students’ mobile phones will become bricks. Of course, students hate it. Therefore, the mobile phone signal jammer cannot be placed in the dormitory, even if it is placed in the dormitory without wall shielding The effect will be stronger, but it won't work, because students will unplug the power plug or even damage it.
Therefore, if you use a small mobile phone signal jammer, it is usually placed under the wall monitoring of the corridor outside the dormitory. Since the signal will be attenuated through the wall, try to choose a jammer with a metal shell and an external antenna, and the power should be as large as possible. One set must be placed at intervals of about ten meters. This is the case on each floor. Let the signals of these mobile phone jammers form a network, which will be much better than using one jammer alone. In the final installation, use one for all the jammers. Connect the power cords to a master switch and control them together during use.
How to install shielding equipment correctly? In fact, schools are more willing to install mobile phone high power jammer outside the dormitory, which saves electricity, is easy to control, and has low radiation. It only needs to take installation points on the adjacent buildings more than ten or twenty meters to shield them. If there is no adjacent building that can be fixed, then a metal pole can be erected on the ground, or if there is a monitoring pole, it can also be fixed on the monitoring pole. After the main body of the shielding device is fixed, the antenna can be erected. Orient the antenna to the building that needs to be shielded, and then adjust the angle and it can be used normally. Note that you must choose a high-power mobile phone signal jammer that is waterproof and rainproof.
