Detention centers are institutions that detain prisoners who have been arrested and criminally detained in accordance with the law. Criminals who are sentenced to fixed-term imprisonment of less than one year, or whose remaining sentence is less than one year and who are inconvenient to be sent to a labor reform facility, may also be supervised by a detention center. The mission of the detention center is to implement armed guarding and guarding of detained prisoners in accordance with national laws to ensure safety; to educate prisoners; to manage the lives and health of prisoners; and to ensure the smooth progress of investigations, prosecutions and trials.
In order to meet the needs of the new situation, improve the scientific and technological prevention capabilities of detention centers, strengthen the scientific and technological management level of detention centers, promote the construction of digital detention centers, promote the harmonious and stable development of detention centers, and continuously improve the modernization level of detention centers, it is necessary to carry out scientific and effective control and prevention of mobile phone signals in detention centers. , to eliminate potential safety hazards caused by illegal use of mobile phones.

However, there are generally three major misunderstandings in the installation of mobile phone signal jammers in detention centers. Let’s take a look at what are the misunderstandings in the installation of mobile phone jammers in detention centers?
Misunderstanding 1: The greater the power, the better
1. The host frequency output is inaccurate, the frequency drifts, the bandwidth is too wide, the power is wasted, and the base station interferes;
2. The simple frequency sweep power suppression method has low shielding efficiency and large radiation;
3. The power is falsely marked and exaggerated, and the nominal power loses its reference value;
4. Power is the foundation, technology is shutdown. Finding good methods and techniques is not as good as trying to gain power;
Myth 2: Using directional antennas can avoid interference
1. There is a certain transmit signal strength outside the directional angle of the directional antenna, but it is much lower than the main lobe and is not completely directional;
2. Reflections from buildings will still cause external interference;
3. The host frequency drift seriously affects the base station and causes external interference;
4. TD full-time shielding interference must exist.
