The shielding effect of the jammer, at this time, you can use a high-power jammer to suppress the mobile phone signal.
Indoor use is different from outdoor use
Indoor use and outdoor use will also affect the shielding effect of mobile phone jammers, including through walls and the separation distance between buildings that need to be considered. 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, the ground and metal objects shield the mobile phone signal The shielding effect of the device will have an impact.
