The cell phone signal jammer is a contemporary communication signal shielding and communication signal shielding technology. Especially in the special environment of prison cells, more regulations have been put forward for mobile phone signal shielding technology. For example, in the application field of general conference communication signal shielding systems, participants come and go in a hurry, and there is almost no time to "find" communication signal shielding blind spots. In special prison environments, the total number is relatively concentrated. Criminals only need to have a mobile phone, and it is very easy for them to "search for a long time" and find blocking blind spots. Even if criminals do not deliberately look for blind spots in blocking, unpredictable short messages will reveal the blind spots that have been ignored.
1. How to evaluate the actual effect of the cell phone signal blocking system in prisons?
In order to achieve no shielding blind spots in the prison, continuous testing should be carried out. Special equipment detectors should be used in areas with relatively strong signals, such as "windows" or "every corner". The contractor can also authorize relevant local departments to do this. Professional inspection of the impact on equipment, radiation sources, and other systems; ensuring no blind spots; complying with the inspection requirements of relevant departments.
2. The problem of shielding effects and the impact of opening up?
A high-quality cell phone signal jammer project must completely shield and at the same time not harm residents' communications. Ordinary people are not allowed to report, and China Mobile and China Unicom are not allowed to cause trouble. Only by ensuring that the shielding area is more accurate and that there is no impact outside the shielding area can it be considered a high-quality mobile phone signal shielding system project. Detailed engineering acceptance of engineering projects.
3. Problems with updating and expanding?
Wireless network communication technology is developing rapidly. 3G is currently in trial operation. Yesterday, the system was completely blocked. Today, problems are likely to occur. Therefore, the basic construction of the shielding system must be modular in design and can be easily updated according to changes in peripheral communication equipment. Only in this way can investment be realistically saved and permanent shielding achieved.
4. System after-sales and engineering construction process
The mobile phone signal shielding system project is a new project with strong technical expertise. An imperfect after-sales service system will definitely hinder the good and long-term operation of the system. Excellent mobile phone signal shielding system dealers and manufacturers have the concept and elite team to provide high-quality after-sales service. They will ensure a series of after-sales maintenance services such as timely phone calls and system updates, and strive to solve customer difficulties.
For new projects in professional fields such as "cells and detention centers", the construction process reflects the technical level of dealers and manufacturers. How the engineering project went, the previous examples are the most contagious.
