Why do jammers work better outdoors than indoors?

    I tested the same jammer equipment indoors and outdoors at the same time, and found that the outdoor shielding radius is larger than the indoor shielding radius. What is causing this?

    Locally, different environmental impacts are also different. The fault area of the open area is larger than the fault area of the building. Therefore, the measured interference radius is usually better than the actual range. Because the test is in an open place. Since the signal may be blocked/interfered by stone walls, the grid will form a Faraday cage (including the "wrong" lead window) and metal such as tin foil insulators, thereby reducing the reliability of indoor wifi jammers. In other words, if you use a portable jammer indoors, the glass may block the signal due to the wall. You may not be able to interfere with the signal in another room.

Howdy, Stranger!
