Cell Phone WiFi Jammer

First, the current situation of the use of wireless signal jammers

First, let's talk about the current status of the use of wireless signal jammers.

1. The area that should be shielded is not strictly shielded, and it costs money and effort to be ineffective;

2. The area that should not be shielded is seriously disturbed, complained and cannot be used normally;

3. There is a gap between too biased belief detection and pseudo base station technology, ideal and reality. At present, there is no real successful case to check in China;

2. Misunderstandings in the use of wireless signal jammers

There are also many misunderstandings in the use of wireless signal jammers

1. The higher the power of the wireless signal jammer, the better

The host frequency output is inaccurate, the frequency drifts, the bandwidth is too wide, the power is wasted, and the base station is interfered;
The simple sweeping power suppression method has low shielding efficiency and large radiation;
Power false standard, exaggerated propaganda, the nominal power loses its reference value;
Power is the foundation and technology is the key. It is better to find good methods and techniques to fight for power recklessly.

2. The use of directional antenna signal jammers can avoid interfering with other locations
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;
The reflection of the building will still cause external interference;
The host frequency drift seriously affects the base station and causes external interference;
TD full-time shielding interference must exist.

3. High-power equipment has large radiation, and low-power equipment has small radiation
High power adopts outdoor antenna function, long operating distance, large shielding coverage, uniform shielding signal but very little radiation;
If the low-power equipment does not use multiple antennas for long-distance shielding, but is centrally arranged or 5 antennas work together, the radiated power will be greater than 10 microwatts/square centimeter, and the short-range radiation must be seriously exceeded;
