  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 their mobile phones to surf the Internet under the bed, and some even in the middle of the night. It is still playing on mobile phones at three o'clock, so in order to prevent students from playing mobile phones in the middle of the night, protect students from external influences, let them rest better, help students focus on learning and improve their knowledge and skills, many schools have to choose Install cell phone jammers in dormitories.

  So is it enough to put a mobile phone signal jammer in each room like the school examination room? The specific situation needs to be analyzed in detail, how to choose and install it. The mobile phone signal jammer installed in the school dormitory is mainly used for students at noon and at night. During rest, noon is usually from 12:30 to 1:30, and at night from 11:30 to 2:00 in the morning. That is to say, it is not required to shield the mobile phone signal for 24 hours without interruption, so the shielding device of the ordinary power supply such as an external adapter can also be selected.

  When installing, it is recommended to connect a timer switch and set the time to work. At that time, there is no need for manual control, and the mobile phone signal jammer can be automatically turned on when it needs to work. Effective segmentation, only interferes with the downlink installation height: 1.0-2.0 meters is the best effect, low energy consumption, energy saving and environmental protection, and does not pose a threat to the health of students and staff. When the jammer is turned on, it will turn students’ mobile phones into bricks. Of course, students hate it, so they can’t put the cell phone signal jammer in the dormitory. Even if it is placed in the dormitory without passing through the wall, the shielding effect will be stronger. Students will pull out the power plug, or even damage it.

  However, if a small mobile phone signal jammer gps is used, it is usually placed under the wall 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. It is necessary to place one set every ten meters or so. This is the case on every floor. Let the signals of these mobile phone jammers form a network, which is much better than using one jammer alone. In the final installation, use one jammer for all the jammers. Root power cords are connected, and a master switch is connected, and they can be controlled together when in use.

  In fact, the school prefers to install a high-power mobile phone signal jammer outside the dormitory building, which saves electricity and is convenient for management and control. It only needs to take the installation point on the building adjacent to ten or twenty meters, and fix the jammer on it. If there is no adjacent building that can be fixed, then set up a metal pole on the ground, or fix it on the monitoring pole if there is a monitoring pole. After the main unit of the jammer is fixed, set up the antenna. Just point the antenna towards the building that needs to be shielded, and then adjust the angle to use it normally. Be sure to choose a waterproof and rainproof high-power mobile phone signal jammer.
