1. The area should be shielded which is not strictly shielded and lt is costly and laborious 。
2. The area should not be shielded and lt has serious interference, lt Is complained and cannot be used normally;
3. There is a gap between biased detection and pseudo base station technology , ideals and reality, and there are no real successful cases in China at present overly;
Misunderstandings of mobile phone signal jammers:
Misunderstanding 1: The greater the power, the better
1. Inaccurate host frequency output, frequency drift, too wide bandwidth, power waste, and interfered base station;
2. The simple frequency sweeping power suppression method has low shielding efficiency and large radiation;
3. The power is false standard, exaggerated publicity, and the 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;
Mobile phone signal jammer
Misunderstanding 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 frequency drift of the host seriously affects the base station and causes external interference;
4. TD full-time shielding interference must exist.
