The full-band jammer system is a relatively professional modern communication signal shielding technology, especially in the special environment of prisons, which puts forward higher requirements for mobile phone signal shielding technology. For example, in the application environment of the communication signal shielding system of a general conference, the participants come and go in a hurry, and there is almost no time to "search" for the blind spot of communication signal shielding. In the special environment of the prison, the number of people is dense and the activities are more concentrated. As long as criminals have a mobile phone, it is easy to "long search" to find blind spots. Even if criminals do not deliberately search for blind spots, the pervasive text messages will expose the missing blind spots.
1. How to evaluate the shielding effect of the monitoring station's full-band jammer system?
In order to achieve no shielding blind spots in the prison, the test should be repeated, and professional equipment detectors should be used in places with strong signals, such as "windows" or "every corners". , radiation, and interference to other systems; do not have blind spots; meet the testing regulations of relevant departments.
2. The problem of shielding effect and external interference?
A high-quality full-band cell phone jammer system project must be completely shielded without affecting the communication of residents, not letting the people complain, and not letting China Mobile and China Unicom find trouble, so that the shielding area is more accurate, and there is no interference outside the shielding area. Only then can it be regarded as a complete acceptance project.
3. The problem of upgrading and expansion?
Wireless communication technology is developing rapidly. Currently, 5G is in the official operation stage. Yesterday, the system could be completely shielded. Today, there may be problems. Therefore, the construction of the full-band jammer system must be modularized, and it can be easily upgraded according to the changes of the surrounding communication facilities, so as to substantially save the project investment and achieve permanent shielding.
4. After-sales service of the system and engineering cases
The full-band jammer system engineering is a highly professional project, and an imperfect after-sales service system will inevitably bring obstacles to the benign and long-lasting operation of the system. Excellent full-band jammer system suppliers and manufacturers have the awareness and team to provide high-quality after-sales service, and will do a series of after-sales services such as regular return visits and system upgrades to effectively solve customer problems. For specialized projects such as "prisons and detention centers", engineering cases represent the technical strength of suppliers and manufacturers. Whether the project is done well or not, the past cases are the most convincing.
Observe whether all the management systems of the prison have been fully implemented and implemented. As the old saying goes, one hundred secrets and one sparse, some individual prison guards or staff inside the prison will try their best to bring mobile phones into the prison for their own private purposes. If these personnel are not self-disciplined enough, do not keep their mobile phones well, or even directly communicate with prisoners, and simply hand over their mobile phones to criminals for use, then things will get worse. For such illegal acts, because the overall process is very hidden, there is no way to If it is discovered and stopped immediately, then as the prison management, it can only adopt the method of installing a mobile phone shielding system to directly shield all mobile phone signals in the prison. In this way, even if a few mobile phones are brought into the prison, due to the existence of the mobile phone shielding system, the mobile phone will have no signal and cannot communicate with the outside world normally.
From the previous analysis, it can be seen that the superficial phenomenon is that the purpose of installing the mobile phone shielding system in the prison is to target criminals from using mobile phones. Serious violation of the prison's restrictions on mobile phone use.
