The importance of installing mobile phone signal jammers in prisons

source:Industry News release time:2021-06-01 Article author:sznbone Popular:Prison Jamming system

  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 and 4G technologies, it will be used in such areas as prisons, labor camps, detention centers, and drug rehabilitation centers. The negative effect of the mobile phone is becoming more and more prominent. In prisons, detention centers and other supervision places, mobile communication tools such as mobile phones are expressly 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 phone calls, send text messages, obtain information, threaten witnesses, and even form gangs and organize escapes. Because of this, the installation of mobile phone signal shielding systems in prisons and other prison places is imminent. Degree!


  At present, China Mobile, China Unicom, and China Telecom have built hundreds of thousands of base stations across the country. The power and number of channels of each base station are not the same, and the distance between each base station and the prison is different. It is generally recommended to install a mobile phone signal shielding system. It is good not to have a base station within two or three hundred meters of the area. If there is a base station, it is important to consider the impact of the base station being too close and the signal being too strong!

  From the influence of the layout of various buildings in the prison

  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. That's not the same. How to arrange the points in each prison needs to be designed according to the actual situation!

  Other influences

  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 also differences in field strength between indoor and outdoor spaces. The ground, building structure, materials and metal objects affect the mobile phone. Shielding the signal causes very complex adverse effects.

  Shielding equipment selection and technical indicators

  Reasonably plan the selection of shielding equipment based on project funding. The selection of shielding equipment should pay attention to the size of its shielding radius (ie power), performance stability, life span, etc., and determine whether to choose the type according to the site environment At the same time, consider using a mobile phone signal jammer with adjustable radius (that is, adjustable power), or using a directional antenna to control the main emission area (direction) of the shielded signal.

  What preparations should be made to establish a mobile phone signal shielding system

  Clarify the scope of the shielded area, whether it is shielded at important points in the prison area (or inside the building) or shielded in the entire enclosed compound; clarify the expected planning and effects of the shielding project, including the planning expenditure of the entire mobile phone shielding project, which is general only To install the shielding device to achieve the shielding effect, or to conduct scientific and intelligent centralized-control shielding; prepare the unit plan and mark the name, layout, size, and floor height of each building in the monitoring area. At the same time, the surrounding environment of the prison should also be marked, especially the location of office areas, houses or social factories within a few hundred meters of the fence; the important point shielding area, the non-important point shielding area and the need not to be shielded Understand the distribution of base stations around the prison (locations and affiliated communication companies); prepare for future mobile phone shielding system construction projects by dealers or manufacturers to conduct on-site surveys and tests; traditional solutions that only install jammers and prison mobile phone shielding Comparison of advantages and disadvantages of network intelligent management system

  Regarding the cell phone signal shielding in a prison or surveillance area, whether it is a method of using low-power jammers for cellular layout, or a high-power mobile phone jammer as the main and a low-power jammer to supplement the blind area, the entire prison area will be Several mobile phone signal shielding points will be installed. For these several shielding points, it is not that the project is successfully completed after the power-on test is installed and the shielding effect is achieved. How to ensure that these several mobile phone signal shielding points are normal and stable in the future The operation of the mobile phone signal shielding project is the key!
