One of the reasons for your cell signal to be weak is that no towers are placed near enough to supply your phone with a strong signal. There can be, however, another cause behind the same problem occurring – that of the signal being blocked by building materials. We’ll take a look at some of the main construction materials that can leave you without a usable signal on your phone.
- Drywall or Sheetrock: A lot of houses these days have ceilings and interior walls made out of drywall. These effectively form the first interior block which can stop signals from getting in, or bring down their strength by 2dB or more.
- Fiberglass Insulation: This can be present in the walls, or even in the attic. When its signal-blocking is combined with that of drywall, you see the signal strength drop to half of what it was.
- Clear Glass: Windows are great to allow in the sun’s light and heat, but the problem is that they can also reflect and refract cellular signal, dropping the strength by up to 4dB.
- Plywood: This is another sheet material which brings down the strength of 3G and 4G LTE signals. It’s even worse if the plywood gets wet because then it acts as a sponge for the incoming signal.
- Solid Wood: A wooden door or furniture made of wood can easily ruin your cell signal. All types of wood are able to absorb and block signals. The thicker it is, the weaker your signal will be.
- Plaster: This is a building material that is made from gypsum, cement, or lime. Plaster is used as a protective coating on ceilings and walls and can make them more effective at blocking signal.
- Brick: Bricks which are made out of cement, shale, or even clay can lend pleasant aesthetics to a home or office. However, they can also shut out the signal coming in from the cell tower.
- Cement and Concrete: This should come as no surprise. Modern buildings these days are almost all made from concrete or cement, both valued for their industrial strength and the consequent ability to form robust structures. The downside is that both interfere with the strength of a signal reaching indoors.
From the above list, it’s clear that almost anything used in building a structure can affect the cellular signal reaching its interior. Signal boosters can greatly reduce the interruption caused by these building materials.
