Mobile phone signal jammer, can it be shielded through the wall through the wall? To answer this question, several situations need to be considered.
First of all, look at the mobile phone signal jammer itself. The mobile phone wifi jammer emits a radio frequency signal specially designed for mobile phone signals. When it encounters the wall in the transmission path, some of the signals will be reflected back, and some of the signals can directly penetrate the wall. But the signal strength will be attenuated to a certain extent. And facing different walls, the attenuation degree of mobile phone jammers is also different. For example, the wall is a reinforced concrete wall or a brick-concrete wall. One wall of reinforced concrete and two continuous walls of brick and concrete, then the interference signal emitted by the mobile phone signal jammer will basically be attenuated, that is to say, it cannot be used through the wall. Therefore, the signal emitted by the mobile phone signal jammer usually cannot pass through the wall. After all, the shielded signal (wireless signal) is not X-ray, and it does not have the ability to penetrate directly, and there will be certain refraction and reflection when it encounters the wall.
Different wall materials have different degrees of attenuation to the mobile phone jammer. For example, if the wall is made of light steel keel gypsum board, its attenuation will be small, and like glass, wooden doors, etc., the attenuation is also small. In addition, if the signal of the mobile phone jammer will also be refracted through the open space of doors and windows or through the reflection and refraction of the wall, it will have some influence on the mobile phone signal behind the wall, so that people feel that the mobile phone signal jammer has the ability to penetrate The illusion of penetration.
Of course, the size of the wall penetration ability is also related to the transmit power of each frequency band of the mobile phone jammer. Generally speaking, the larger the transmitting power, the stronger the penetrating ability. It is the same as listening to the sound of the next door through a wall. If the sound of the next door is louder, you can hear it clearly. won't hear it.
The ability to pass through walls is also related to the frequency of the wireless signal emitted by the mobile phone jammer. We all know that the lower the frequency of the wireless signal, the stronger the diffraction performance, just like the radio stations that everyone usually listens to. The frequencies emitted by radio stations are basically tens of megabytes to more than 100 megabytes, and the frequency is very low. One transmission tower can cover more than 100KM. The lower the frequency of the wireless signal, the stronger the penetration ability will be.
Therefore, when using a mobile phone signal jammer, if it can be determined that the wall is made of gypsum board and wood board, then you can choose whether to install it on a partition wall. If the wall is made of brick or steel, it is not recommended to install a mobile phone jammer on the partition wall.
