Have you noticed that you may have complete 5G or 4G signals outside, but your phone signal is not good when you enter the building? Even in cities surrounded by 5G and 4G signal towers, it is difficult for mobile signals to pass through walls.
Depending on the type of material used in construction, mobile phone signals may be more or less blocked. Non conductive materials such as wood, gypsum board, plastic, and glass can obstruct but not block cellular signals. Materials such as tin, copper, silver, and aluminum can completely block signals. Let's study these materials that block mobile phone signals.

What constitutes your building can largely determine how poor your internal services are, but the location of your building is also important. Learning how to enhance cell signals in forests can counteract some of the effects of cell blockage on building materials.
Most homes and small offices are made of wood, plywood, fiberglass insulation, and glass. Compared to smaller wooden buildings, large brick or metal buildings are more effective in blocking signals. Add all these materials together and put them in the building, and you can answer why there is no mobile service inside.
The wall is divided into brick concrete, steel concrete, and other materials, such as glass, wood, gypsum board, etc. The penetration order of mobile phone signal shielding devices on the wall is: glass>gypsum board>wood>brick concrete>reinforced concrete wall.
The thinner the wall, the greater the penetration force.
The mobile phone signal blocker consists of RF modules with different frequencies. The lower the signal frequency, the better the wall penetration effect, such as 800>900>1800>2100>2300>2600.
The higher the power of the mobile phone signal jammer module, the stronger its penetration.
