Can cell phone jammers be shielded through walls?

　　Can the cell phone signal jammer gps be shielded through the wall through the wall? To answer this question, several situations need to be considered.

　　First of all, look at the shielding device itself. The shielding device emits a wireless radio frequency signal specially designed for mobile phone signals. This radio frequency signal will be attenuated when it encounters obstacles in the transmission path, and the attenuation caused by passing through different obstacles The degree is different, such as facing the whole steel-concrete wall or brick-concrete wall, a reinforced concrete wall and a continuous two-sided brick-concrete wall, which can basically block the signal shielding of small and medium-power mobile phone signals. The RF signal is attenuated.

　　Therefore, shielding mobile phone signals usually cannot pass through walls. After all, shielding mobile phone signals is not X-ray, and does not have the ability to penetrate and directly penetrate, and there will be certain refraction and reflection when encountering walls.

　　In some cases, different wall materials have different degrees of attenuation to shielding mobile phone signals. For example, if the wall is made of light steel keel gypsum board, its attenuation is small, like glass, wooden doors, etc., Attenuation is also smaller.

　　In addition, if the mobile phone signal is shielded, it will also have some influence on the back of the wall through the open space of doors and windows or through the reflection and refraction of the wall, so as to give people the illusion that the mobile phone signal shielding device has the ability to penetrate.

　　Whether it is a high-power mobile phone signal shielding device or a medium and small power mobile phone signal shielding device, it is not recommended to use it through the wall, the main reason is that the shielding effect cannot be guaranteed. Therefore, when choosing to install the signal blocker, try to install it in the place where the mobile phone signal needs to be shielded, and do not use it through the wall.
