When testing, place it in a conference room. Try to place it on the wall sides near the windows at both ends of the conference room, and try to place the signal jammer as high as possible. If site conditions are limited, it can also be placed directly on the conference table, but be careful not to place it directly on the ground. Depending on the conference room environment, choose the other end of the conference room, or choose a location diagonally opposite.
