We often receive such requests from some customers: expect to purchase a mobile phone signal jammer that is small in size, light in weight, and easy to carry. The interference signal penetrates the wall to cause signal interference to the area on the other side of the wall.

According to the customer's expectations, the selection of equipment is actually to find a low-power mobile phone signal jammer. Of course, we have suitable models for this type of product to recommend, but the next question is: can it penetrate through the wall to achieve interference? What about the effect of the indoor signal?

Before answering this question, we must first understand two key information points: the first is the characteristics of the signal transmission, and the second is the influence of the wall material on the signal penetration through the wall.

About the characteristics of signal transmission: the mobile phone signal jammer we provide, the interference signal emitted is actually a white noise interference signal corresponding to the working frequency of the mobile phone. To put it bluntly, this is the wireless radio frequency signal, the characteristics of wireless signal transmission, and X-rays are not the same type, X-rays can go right through walls. If a wireless signal encounters a wall during transmission, it is somewhat similar to a light wave or a sound wave, and its ability to directly penetrate is very limited, and more of it reflects the phenomenon of diffraction, reflection, and refraction of the wireless signal.

Let's pay attention to the influence of wall material on the signal penetration ability. Different wall materials and wall thicknesses have different effects on the penetration ability of wireless signals. Let's take the interference signal emitted by the mobile phone signal jammer as an example. If the interference signal is facing a completely solid reinforced concrete wall, then this material will reflect and refract almost all the interference signal back, and directly penetrate the wall. Interfering signals are almost negligible. But if the interference signal is facing an ordinary brick wall, the ability of the interference signal to penetrate the wall will be stronger than that of reinforced concrete, but the degree of signal attenuation will still be relatively large. Let me illustrate with another example: If the interference signal is facing a gypsum board wall or a glass partition, then when the signal penetrates this type of wall, the attenuation of the signal directly passing through is not large, and the attenuation value is usually 5 -8dB.

Finally, to sum up, can the low-power mobile phone signal jammer penetrate through to achieve the effect of interfering with the signal in the house? On the one hand, this depends on the transmission power of the interference device itself. In essence, of course, the greater the transmission power, the more obvious the effect of interference signal penetration. On the other hand, it also depends on the material and thickness of the wall. When encountering a completely solid reinforced concrete wall, it is somewhat unrealistic to expect interference signals to pass through the wall.
