block cell signal in room

In order for the mobile phone signal jammer to effectively interfere with the mobile network, it must be ensured that the signal field strength of the jammer should be much greater than the field strength of the mobile signal BCH in the interference area. Therefore, the same jammer uses different locations and the effective area size of the interference However, the local BCH field strength is generally stronger as it is closer to the base station, and the area where the jammer reaches effective interference is smaller. Generally, the interference radius can only reach 0.5-9m; if the farther away from the base station, the BCH field strength is relatively weak. Then the radius of the jammer to achieve effective interference is larger, up to ten to tens of meters.
