Do you know how some special departments should choose a mobile phone signal screener? I believe that many of my friends don’t know much about it, so today I will explain it to you, come and see!

If ordinary civilian mobile phone signal jammer devices are used in places where mobile phone shielding is strictly required, such as prisons, what will be the performance? I think there are the following manifestations:

1. The shielding effect of the shielding area is not strict, and there are a lot of blind spots and dead corners. In some areas of the prison area, there are many areas near the window, especially on the side of the base station, which can be connected to mobile phones, and even some antennas (equipment) can still be connected. Calls leave opportunities for criminals, and cannot achieve the purpose of comprehensively preventing illegal use of mobile phones.

2. Severe interference in areas that should not be shielded: The office buildings and armed police areas outside the second gate of the prison are severely interfered, affecting the normal life and work of the staff; more serious interference will further expand, and even interfere with the base station to paralyze it. Communities, factories, and units have been subject to strong interference in large areas, and people are very angry; complaints from residents and operating departments such as China Mobile, China Unicom, and Telecom, as well as investigations by local radio management departments, these problems have brought a certain negative impact on the normal work of the prison. , disrupting the harmony of police-community relations.

3. Unstable system operation: good and bad, low reliability, frequent failures. Especially in summer and autumn, a large number of equipment failures are damaged, although a large number of equipment replacements still cannot achieve the expected shielding effect; in exchange for continuous maintenance, it will cost lives and money, and it is like a chicken rib.
