What are the safety misconceptions about cell phone jammers in detention centers?

Custody is in accordance with regulations. Governing bodies led by detainees. For criminals who are inconvenient to be sent to the scene for execution, if the criminal is sentenced to one year in prison or the remainder of the sentence does not exceed one year, the detention office will also control them. The daily tasks of detention facilities are to carry out armed warning and surveillance on detainees in accordance with the law to ensure their safety; provide cultural education to prisoners; manage the daily life and environmental sanitation of criminal prisoners; and ensure investigation. Prosecution and trial proceed smoothly.

In order to better adapt to the needs of the new normal, improve the technological protection capabilities of the detention center, improve the technological management capabilities of the detention center, promote the construction of intelligent detention centers, promote the harmonious and stable development of detention centers, and continuously improve the detention center The level of intelligence at work requires scientific and reasonable adjustment and prevention of mobile phone signals in residence to avoid safety risks caused by illegal use of mobile phones.

However, there are generally three major misconceptions about installing cell phone signal jammers in detention centers. Let’s take a look at the safety misconceptions about cell phone jammers in detention centers.

Misconception 1: The greater the output power, the better

1. The server frequency output is inaccurate. The frequency changes. The network bandwidth is too wide and the output power consumption affects the communication base station;

2. The simple frequency offset output power suppression method has low shielding efficiency and the radiation source is relatively large;

3. The power is falsely high. Exaggerated propaganda will cause the power to lose its value;

4. Output power is basic, technology is standby. Trying to achieve output power is not as good as finding good methods and methods;

Misconception 2: Choosing directional antennas can prevent the impact

1. The directional antenna also has a certain transmitting and receiving sensitivity outside the fixed angle, which is just much lower than the main lobe and is not completely fixed;

2. Reflective residential buildings will still have an opening effect;

3. The change of server frequency seriously affects the communication base station and affects the opening to the outside world;

4.TD all-day shielding effect is bound to exist.

Misconception 3: Machinery and equipment with high output power have large radiation sources, while machines with low output power have small radiation sources.

1. Choose a TV antenna with high power, long service distance, large shielding coverage, uniform shielding signal and very few radiation sources;

2. If the low-power equipment does not use multiple antennas to extend the shielding distance, but is placed centrally or 5 antennas work together, the radiation illumination will exceed 10 microwatts/cubic centimeter, and the radiation source will be close to the source. It must be quite serious and exceed the standard;
