How to plan and design the mobile phone signal shielding system project in the prison?
At present, more and more prisons have installed cell phone signal jammer systems, and we often receive project consultations from prisons. Some of the problems in the consultation process can be brought up for discussion and provide us with reasonable solutions. suggestion. For example: Some customers have the general requirement for the goal of building a mobile phone signal shielding system project for a prison, or the final effect, that the shielding signal must be 100% effective in covering all areas within the prison wall. However, the prison’s The fence is used as the boundary, and the office area outside the fence, the armed police patrol department, and the ordinary houses and factories near the prison should all be guaranteed not to be affected by the shielding signal. So, is such an overall project requirement put forward by the client reasonable? Can it fully achieve the shielding effect expected by customers? If it is not reasonable, how should the cell phone signal shielding system project of the prison be planned and designed?
First of all, we have to make it clear that the shielding signal emitted by the mobile phone signal shielding system is a radio frequency signal. The transmission and coverage of this wireless signal will affect the coverage and coverage of the shielded signal due to the directional antenna or omnidirectional antenna it uses. Covering direction and so on to control a certain range or distance. However, the control of the range or distance of wireless signal transmission can only be a macroscopic and broad control level at present, and it is not possible to achieve a very precise distance limit, and it cannot be realized with the prison wall as the boundary. It is almost impossible to achieve a wall where the signal inside the wall is completely shielded and the signal outside the wall is not affected at all. In reality, our suggestion is to first ensure that the shielding signal inside the fence can be fully covered, and a buffer zone of at least 20 to 50 meters should be allowed outside the fence. In this buffer area, the influence of the mobile phone signal shielding system may appear from time to time.
Next, let's discuss whether it is reasonable to require full coverage within the prison wall and no dead ends for shielding signals? Our suggestion is: each area in the prison can be divided into key areas and non-key areas. For the shielding signal of the mobile phone signal shielding system in key areas, the signal coverage must be all-round and without dead ends. In non-key areas, you can selectively confirm whether complete coverage is required after analyzing the actual situation. The non-key areas in the prison include: the warning isolation zone near the wall, the outdoor square and the open field of vision, the public activity area, the hall or corridor aisle and other areas where video prisons are installed, etc. The reason why it is suggested that these non-key areas can be considered not to do signal shielding, in fact, we only need to imagine, what is the purpose of installing a mobile phone signal shielding system in the prison? It is to prevent detainees from secretly using mobile phones. As for the non-key areas mentioned above, it is obvious that no inmates will blatantly use mobile phones in these places.
In addition, not installing mobile phone signal shielding systems in non-key areas of the prison can also reduce project construction costs and save investment. This does not mean that we cannot do it in terms of equipment or technical capabilities. If the prison has sufficient budget funds and is willing to spend a lot of money to build a perfect mobile phone signal shielding system project, we also agree very much!
