① The higher the power, the better
1. The host frequency output is inaccurate, frequency drifts, the bandwidth is too wide, power is wasted, and interferes with the base station;
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;
② Use directional antennas to 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.
③ High-power equipment has large radiation, while low-power equipment has small radiation.
1. High-power uses an outdoor antenna, with long operating distance, large shielding coverage, uniform shielding signal but minimal radiation;
2. If low-power equipment does not use multiple antennas to provide long-distance shielding, but is centrally arranged or 5 antennas work together, its radiation power will be greater than 10 microwatts/square centimeter, and close-range radiation must seriously exceed the standard.
