So what are the factors that affect the shielding effect of mobile phone jammers?
The power of mobile phone jammers can be large or small. The shielding distance of signal jammers is relatively far, and for places with strong signals, such as a base station between 100 and 200 meters or a mobile phone signal installed Jammers will all affect the shielding effect of signal jammers. At this time, jammers with can be used to suppress mobile phone signals.
Indoor use and outdoor use are different. Indoor use and outdoor use will also affect the shielding effect of mobile phone jammers, including through walls and the separation distance between buildings. The position and spacing of the video signal and the position of the mobile phone shielding area also endanger the actual effect of shielding.
In the actual use environment, due to the different characteristics of the direction and distance of the signal tower, there may be dozens of channels for the user's mobile phone to automatically select in the same environment, and the difference in field strength between indoor and outdoor, and the ground and metal objects interfere with the signal of the mobile phone. The shielding effect of the device will have an impact.
Therefore, when selecting a signal jammer, it is necessary to have a detailed understanding of the environmental area and shielding distance of the shielded place, and conduct a thorough analysis of the local signal, whether there are base stations around it, and the structure of the building.
