Many customers hope that the purchased signal jammer has the function of penetrating the wall, and even hope that the signal jammer can directly penetrate the two walls and still maintain sufficient strength. So, can such expectations be realized?
This needs to distinguish the material of the wall. If the interference signal of the signal jammer is in the transmission path and encounters a reinforced concrete wall, the interference signal will be almost completely attenuated and reflected. Behind such a wall, the received The interference signal from the signal jammer will be very weak, even close to 0. If a second wall is encountered, the interfering signal will be completely attenuated. For example: in the elevator shaft in the building and in the underground parking lot, if there is no mobile phone signal amplifier installed, there will be no mobile phone signal in these two places, because the base station signal of the outdoor mobile phone operator cannot penetrate the steel bar at all. Concrete wall.
Let's look at some other strong materials. If the interference signal of the signal jammer is in the transmission process, it encounters a wall made of wood, or a wall made of glass, ABS plastic and other materials. The attenuation effect is very limited. When the interference signal of the signal jammer penetrates these materials, the signal strength error is very small. Even two such walls in a row can still receive a strong interference signal.
Based on the above content, the problem of whether the interference signal of the signal jammer can penetrate the two walls has little to do with the signal jammer itself, but should focus on the material characteristics of the wall.
