Can the jamming signal of the 5G signal jammer continue to penetrate two walls?

Customers often expect 5G signal jammers to be able to penetrate walls, and even expect the jammers to maintain sufficient strength when passing through two walls. The realization of this expectation depends on the wall material.

When the interference signal of the 5G jammer encounters a reinforced concrete wall on the transmission path, the signal will be significantly attenuated and reflected. Behind such a wall, the interference signal received by the 5G jammer will be very weak, possibly close to zero. If it encounters a second wall, the interference signal will be completely attenuated. For example, in a building without a mobile phone signal amplifier, areas such as elevator shafts and underground parking lots will have no mobile phone signals at all, because outdoor base station signals cannot penetrate steel and concrete walls.

Now let’s consider other strong materials. If the interference signal of the 5G cell phone jammer passes through walls made of materials such as wood, glass, ABS plastic, etc. that are not suitable for blocking wireless signals, the attenuation effect on the 5G signal jammer will be minimal. Even if the interference signal penetrates two consecutive walls made of such materials, a strong interference signal can still be received.

Based on the above information, the ability of the 5G signal jammer to penetrate two walls depends more on the characteristics of the wall material than on the jammer itself.
