Can a small -power mobile phone signal shielding system penetrate the wall from the wall to achieve the effect of interference in the inside of the house?
We often receive some customers to put forward such demand: expect to purchase a cell phone signal jammer with small body shape, light weight, and easy to carry. The usage scenario is a bit special. When turning on the interference equipment, at least one wall is across the wall. Put the interference signal penetrating the wall to generate signal interference effects on the area on the other side of the wall.
According to the content of the customer's expectations, the equipment selection is actually to find a small -power mobile phone signal shielding system. Of course, we have the appropriate model to recommend this type of product, but the next question is: Can you penetrate it across the wall and achieve interference to interference. What about the effect of the signal in the house?
Before answering this question, we must first understand the two key information points: the first is the characteristics of the lower signal transmission, and the second is the impact of the wall material on the signal penetration of the wall.
Regarding the characteristics of signal transmission: The mobile phone signal shielding system provided by us, the interference signal emitted is actually a white noise interference signal corresponding to the frequency of the mobile phone. X -rays are not the same type, X -rays can penetrate the wall directly. If the wireless signal encounters the wall during the transmission process, it is a bit similar to light waves or sound waves. The ability to penetrates is very limited. It is more reflecting the phenomenon of radiating, reflection, and refractive phenomenon of wireless signals.
Let's pay attention to the impact of the wall material on the penetration ability of the signal. The effects of different wall materials and the thickness of the wall on the penetration of wireless signals are different. We take the interference signal emitted by the mobile phone signal shielding system as an example. If the interference signal is facing a completely essential reinforced concrete wall, then this material will reflect the interference signal almost all of them, reflect it back, and directly penetrate the wall of the wall. The interference signal can be ignored. However, if the interference signal is facing ordinary brick walls, the ability to interfere with the signal penetrating the wall will be stronger than the reinforced concrete, but the degree of signal attenuation will still be relatively large. For example, if you interfere with the signal facing the gypsum board wall or glass strong, the signal penetrates this type of wall, and the degree of attenuation of the past signal is not large. -8db.
Finally, can the small -power mobile phone signal shielding system be penetrated to achieve the effect of interference in the house? On the one hand, it depends on the launch power of interference equipment itself. In essence, the greater the transmitting power and 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 it encounters a completely solid reinforced concrete wall, it is not realistic to expect to interfere with the signal through the wall.
