To install a wireless jammer on a certain floor of a building, I only hope that the interference signal of the wireless jammer will cover my room, but not affect the upper and lower floors. Can my request be realized? How can I do it without affecting the wireless signal upstairs or downstairs?
The structure of the building is usually a reinforced concrete structure, and reinforced concrete is used as the interlayer material for the upper and lower floors. In fact, it can have a great attenuation effect on the interference signal of the wireless jammer, and the greater the thickness, the attenuation effect. The bigger it is! According to the actual test results, when the thickness of completely solid reinforced concrete exceeds 300mm, the interference signal of the wireless jammer is almost completely unable to penetrate.
But why do some customers give feedback that after the wireless jammer is turned on, the wireless signal on the upper and lower floors is still interfered to a certain extent. In fact, this is closely related to the installation location of the wireless jammer. After the interference signal is emitted, in addition to penetrating some obstacles, it also has the characteristics of reflection and refraction. If the wireless jammer is installed near the outside of the building, such as near the window, then it is obvious that the window has little effect on the error of the jamming signal, and the jamming signal can be transmitted normally, through refraction and reflection phenomenon, it is easy to affect the upper and lower floors.
The solution to the problem is: the wireless jammer must be installed as far as possible in the central area of the floor, and as far away from the window as possible. Moreover, it is better to have a wall as an obstacle between the installation location and the window to prevent the interference signal from being directly transmitted to the outside of the building.
