What are the installation errors of cell phone signal jammers in detention centers?

First, the bigger the power, the better

1. The frequency output of the host is inaccurate, the frequency drifts, and the bandwidth is too wide, which wastes power and causes interference to the base station.

2. The shielding efficiency of the simple frequency sweeping power suppression method is not high, and the radiation generated is relatively large.

3. The power is falsely marked and the publicity effect is exaggerated, so that the nominal power has no actual reference value.

4. Power is the foundation, and technology is the shutdown. If the power is reckless, it is better to find the correct methods and techniques.

Second, the application of directional antennas can avoid interference

1. There is still a certain transmitted signal strength outside the directional angle of the directional antenna, but it is much lower than the main lobe, and it is not completely directional.

2. The reflection of the building will still cause interference to the outside world.

3. The frequency drift of the signal jammer host will seriously affect the base station, thereby causing external interference.

4. TD full-time shielding interference must exist.

Third, the radiation of high-power equipment is large, and the radiation of low-power equipment is small

1. High-power application of outdoor antenna, which has long operating distance, large shielding coverage, uniform shielding signal, and very small radiation.

2. If the low-power device does not use multiple antennas for long-distance shielding, but instead is concentrated or 5 antennas work together, the radiated power will be higher than 10 microwatts/square centimeter, and the short-range radiation will definitely be Severely exceeded.
