With the continuous development and popularization of mobile communication tools such as mobile phones, and the continuous improvement of the technical level of personal mobile communication methods, especially after the promotion and application of 3G, 4G, and 5G technologies, it will be used for prisons, labor camps, detention centers, drug rehabilitation centers, etc. The negative effects of similar areas are becoming more and more prominent. In prisons, detention centers and other supervision places, mobile communication tools such as mobile phones are explicitly prohibited, not only for prisoners, but also for supervisors. Once the mobile phone is brought into the prison and put into use, it will bring great harm to the management, safety and development of the prison. Some prisoners use illegally smuggled mobile phones to make calls, send text messages, obtain information, threaten witnesses, and even form gangs and organize escapes. Because of this, the installation of cell phone signal jammer in prisons and other prison places is imminent. Degree!
What factors should be considered in establishing a mobile phone signal shielding system
Due to the influence of the base station, the distance between each base station and the prison is different. Generally, it is recommended that there is no base station within two to three hundred meters near the prison area where the mobile phone signal shielding system is installed. Strong influence!
The scale, number of buildings, structure, size, floor height, etc. of each prison are different. The distribution direction, power, and terrain of mobile phone base stations around each prison are different. The strength of mobile phone signals transmitted from remote base stations is also different. There is no difference. How to arrange the points in each prison needs to be designed according to the actual situation!
Even in the same environment, the base station signal is affected by wind disturbance, air humidity, etc., which will cause fluctuations in signal field strength. In addition, there are differences in field strength between indoor and outdoor spaces, and the ground, building structure, materials and metal objects affect the mobile phone. Shielding the signal causes very complex adverse effects.
Cell phone signal shielding systems are installed in prisons. Most shielding terminals are installed in relatively high or slightly hidden locations, and are not detected by ordinary people, but they may not prevent man-made damage. The influence of future human factors must be considered, including prisons. Guilty (also resisted by prison guards) artificially damaging or cutting off the power supply to the jammer,
With the accumulation of working hours, electronic products such as mobile phone signal jammers will also have normal wear and tear. Several shielding points installed in the prison cannot be guaranteed to operate 100% stably every day. As a manager, you should have a set The simple and convenient centralized control system can detect the man-made damage or normal loss of the shielding point in time, and arrange the maintenance and inspection quickly.
