Questions about the wifi jammer in the detention center? from dojammer's blog

The advancement of science and technology has added great convenience to everyone's daily life, especially in the past two years, communication technology has advanced rapidly, and many data wifi jammer manufacturers are updating their equipment for the development of the times. In order to be able to integrate into the requirements of the new business model, high-tech can improve the innovative technology prevention and control business capabilities of the detention center, improve the innovative technology management level of the detention center, and promote the construction of intelligent infrastructure projects. Systematic detention centers, promote the harmonious and stable development of detention centers, and continuously improve the level of intelligent systems in detention centers. Standardize and efficiently manipulate and prevent detention center signals, and eliminate potential safety hazards caused by illegal use of mobile phones.

Problem 1: Interference can be avoided by using directional antennas

1. The azimuth angle of the directional antenna has a certain emission point signal, which is only much lower than the main lobe, and is not completely fixed;

2. The vertical surface of the building will still interfere with the expansion of the opening;

3. The output power drift of the network server seriously threatens the mobile base station, causing the expansion of open interference

4. TD 24-hour shielding interference must exist.

Question 2: The bigger the power, the better

1. The output power of the network server is not accurately derived, the output power drifts, the server bandwidth is too wide, power consumption, and mobile base station interference;

2. The shielding efficiency of the simple frequency offset power suppression method is not high, and the radiation is large;

3. The power is too high, exaggerated, publicized, and the standard power lacks practical significance;

4. Power-based, technology-based. It is better to find good methods and techniques than to fight hard;

Question 3: The radiation of high-power mechanical equipment is large, and the radiation of low-power mechanical equipment is small

1. The function of high-power TV antenna, the effect distance is long, the shielding range is large, the shielding signal is uniform, and the radiation is particularly small;

2. Low-power mechanical equipment uses multiple external antennas without long-distance shielding, centralized and precise positioning, or when 5 external antennas work together, the radiation power exceeds 10 microwatts/cubic decimeter, and the short-distance radiation has always exceeded the standard.
