Signal coverage design of prison 5G signal jammer
Nowadays, more and more prisons have installed 5G signal jammers, and there are also some problems during the consultation process. For example: the overall requirement is that the shielded signal covers 100% of the area within the prison wall, but with the prison wall as the boundary, office areas outside the wall, armed police patrol departments, and ordinary residential buildings and factories close to the prison should be protected from shielded signals. Impact.
What needs to be made clear is that the shielding signal emitted by the 5G signal jammer is a radio frequency signal. Although the transmission and coverage of this wireless signal will affect the coverage and coverage direction of the shielding signal due to the directional antenna or omnidirectional antenna used, it is Control within the corresponding range or distance. However, the control of wireless signal transmission range or distance is currently only a macro-level and broad-level control. The distance limit of [sensitive word] cannot be achieved yet, and the prison wall is used as the boundary. The recommendation for building a shielding system is to first ensure that the shielding signal within the fence can be covered, and leave at least a 20 to 50 meter buffer zone outside the fence. Within this buffer, the effects of signal masking may appear intermittent.
Secondly, the suggestion is that every area within the prison can be divided into key areas and non-key areas. The 5G signal jammer shields signals in key areas to provide full signal coverage without blind spots. For non-key areas, you can selectively confirm whether full coverage is required based on the actual situation. Non-key areas within the prison include: warning isolation belts near the walls, outdoor squares and areas with wide views, public activity areas, halls or corridors and other areas where video prisons are installed. In addition, not installing jammers in non-key areas of the prison can also reduce project construction costs and save investment.
