It is often mentioned that the interference effect of signal jamming will be weak if there is a wall. There are several possibilities: First, look at the  signal jamming  itself. The signal jamming transmits radio frequency signals specifically for signal jamming. It will attenuate when encountering obstacles in the transmission path, and the error degree of different obstacles is differ...
