The status and error of cell phone shield in prison
1、 Status quo:
1. The area that should be shielded is not strict, and the cost is not effective;
2. The area without shielding is seriously disturbed, complained and can not be used normally;
3. There is a gap between over bias detection and pseudo base station technology, ideal and reality, and there are no real successful cases in China;
2、 Misunderstanding:
① The higher the power, the better
1. Base station with inaccurate frequency output, frequency drift, wide bandwidth, waste of power and interference;
2. The simple sweep power suppression method has low shielding efficiency and large radiation;
3. The nominal power loses its reference value by false power standard and exaggeration publicity;
4. Power is the basis, technology is the key. Hard work power is not as good as finding good methods and skills;
② Directional antenna can avoid interference
1. The intensity of the transmitting signal is much lower than the main lobe, but not completely oriented;
2. The reflection of buildings will still cause external interference;
3. The frequency drift of the host seriously affects the base station and causes external interference;
4. TD full time shielding interference must exist.
③ High power equipment radiates greatly, and low power radiation is small
1. The high power adopts outdoor antenna, which has long range of action, large shielding coverage and even shielding signal, but it radiates very little;
2. If the small power equipment does not use multi antenna pull long-distance shielding, but is centrally arranged or five antennas are combined, the radiation power will be greater than 10 microwatts / square centimeter, and the radiation near distance must be seriously over standard;
