Can the shielding device that shields the mobile phone signal pass through the wall?

People often ask whether the shielding device used to shield mobile phone signals can 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 signal jammer emits a wireless radio frequency signal specially designed for mobile phone signals. It will attenuate when it encounters obstacles in the transmission path, and the error degree of different obstacles is different. The whole steel-concrete wall or brick-concrete wall, one reinforced concrete wall and two consecutive brick-concrete walls can basically attenuate the shielded mobile phone signal, so shielding the mobile phone signal is usually impossible. If it goes through the wall, after all, it blocks the mobile phone signal (wireless signal), it is not X-ray, it does not have the ability to penetrate directly, and there will be a certain degree of refraction and reflection when it encounters the wall.

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 blocked, it will also have some influence on the back of the wall through the open space of the door and window or through the reflection and refraction of the wall, so that people have the illusion of penetrating ability.
