The wifi jammer is definitely different in the outdoor and outdoor environments. We do not recommend using the same device in two different environments, especially the indoor wifi jammer device is used in the outdoor environment, because the outdoor is relatively The complex and harsh environment makes us have higher requirements for outdoor shielding equipment, such as temperature, climatic conditions and so on. In addition, the effective shielding distance of wifi frequency jammer has nothing to do with indoor and outdoor. It is closely related to the on-site mobile phone signal strength, and the mobile phone signal strength is very different indoors and outdoors. This requires an in-depth understanding of signal transmission. Know, the effective shielding distance in the general equipment parameters is the distance measured for a specific environment (such as -60dB in an open environment). Therefore, when choosing a wifi jammer, you must consider comprehensively and choose carefully.
How to choose a wifi blocker?
As we all know, the wifi jammer is to block the signal received by the mobile phone from the base station, and it will attenuate when it encounters obstacles. If it is a solid wall of reinforced concrete, the attenuation after penetration is very large; if it is gypsum board, the attenuation is smaller; if it is glass or wood, there is basically not much attenuation. Here's how to detect the effect of a wifi frequency jammer.
One: Take a used can, clean it, pull out the pull ring
Two: Circumcising the bottom of the tank to remove the entire bottom
3: Make a circular cut on the top of the tank, be careful not to cut all of it, leave 1-2 cm part without cutting, and the remaining 1-2 cm part must be close to the tank mouth
Four: Draw a red line vertically on the reverse side and cut off the iron sheet along the middle of the red line
5: Spread the cut iron sheet slowly and slowly to make a fan shape.
Six: Put the finished fan-shaped iron shell on the wifi jammer antenna.
At this time, take out the mobile phone and start to detect the effect of blocking the signal.
