1. Current situation:
1. The area that should be shielded is not strictly shielded, which is costly and laborious and has no actual effect;
2, the area that should not be shielded has serious interference, and is complained and cannot be used normally;
3. There is too much bias between detection and pseudo base station technology, there is a gap between ideal and reality, and there are no real successful cases in China to check;
2. Misunderstanding:
① The greater the power, the better
1. Inaccurate host frequency output, frequency drift, too wide bandwidth, waste of power, and interfered base station;
2. The simple frequency sweeping power suppression method has low shielding efficiency and large radiation;
3, false power standards, exaggerated publicity, nominal power loses its reference value;
4. Power is the foundation and technology is the key. It is better to find good methods and skills to fight for power;
② Using directional antennas can avoid interference
1. There is a certain transmitted signal strength outside the directional angle of the directional antenna, but it is much lower than the main lobe, not completely directional;
2, the reflection of the building will still cause external interference;
3, the host frequency drift seriously affects the base station, causing external interference;
4. TD full-time shielding interference must exist.
③ The radiation of high-power equipment is large, and the radiation of low-power is small
1. The high-power uses an outdoor antenna, which has a long range, large shielding coverage, uniform shielding signal, and minimal radiation;
2. If the low-power equipment does not use multiple antennas for long-distance shielding, but is arranged in a centralized manner or 5 antennas are used together, its radiation power will be greater than 10 microwatts/square centimeter, and the short-range radiation must be seriously exceeded;
