Ensuring Optimal Signal Blocking Effectiveness
In the course of daily work, it is common to receive inquiries from distributor clients regarding the design of cell phone signal jammers for supervisory facilities. One crucial aspect to consider in the design of these jammers is the appropriate installation location, as it directly affects the final signal blocking effectiveness. This article aims to provide guidelines for clients in designing cell phone signal jammers for supervisory facilities.

1. Installation Position in Detention Centers:
Detention centers typically have reinforced concrete walls that cause significant attenuation of wireless signals. Therefore, the installation position of the signal jammer should be as close as possible to the opposite side of the doors and windows, as the interference signals can only enter the rooms through them.
2. Placement in Supervisory Buildings:
For conventional low-power signal jammers, the effective shielding radius in an open environment is 10-20 meters. In supervisory buildings, it is recommended to install one jammer for every 2-3 cells, considering the layout of the cells. Additionally, it is advisable to install a separate cell phone signal jammer in areas such as public restrooms, bathrooms, and laundry areas. If there are courtyards or exercise yards, a certain number of cell phone jammers may also be required.
3. Cellular Layout for Supervisory Facilities:
Based on the layout of various buildings within the supervisory facility, the cell phone signal jammers should be deployed in a cellular pattern. Although this may result in some overlapping coverage areas, it helps to avoid the creation of signal blind spots to a certain extent.
4. Outdoor Signal Interference:
If signal interference is required in the outdoor environment of the supervisory facility, it is recommended to first use high-power cell phone signal jammers around the perimeter to cover the main areas. Then, identify any blind spots in signal coverage within the facility and supplement them with a few low-power cell phone jammers.
5. Installation of High-Power Jammers:
When installing high-power cell phone signal jammers around the supervisory facility, it is advisable to mount them on patrol post buildings or utilize existing structures such as fences or lampposts. In cases where installation on wire mesh fences is inconvenient, standalone lampposts can be used instead.
Designing an effective cell phone signal jammer system for supervisory facilities requires careful consideration of the installation location. By following the guidelines outlined in this article, clients can ensure optimal signal blocking effectiveness and enhance the security and control within these facilities.
