Cell Phone reception is a very common issue, and it can be due to multiple reasons such as environmental conditions, bad network coverage and the building materials of your home or office. Whatever may be the reason, it can be quite frustrating, and one of the effective methods to resolve this is using a cellular signal booster. It is an ideal solution for home or office when you have varying signal quality at your place. So, how building materials affect cell phone reception?

What Causes Drop In Cellular Signal Reception At Home?

Cellular signals are radio waves and their strength is reduced as they pass through different mediums. So, the attenuation in its strength by the environment is from -5dB to -25dB, by rain it is -1dB to -5dB and due to foliage it is -1dB to -25dB. But, the biggest drop is due to some of the common building materials used in the construction of our homes and offices.

Listed below are the drop in cellular signal strength due to some common building materials.

Plain Glass

It is due to the misconception that glass and window panes give better reception, people move towards them when the cellular signal reception is bad. There is nothing more untrue than this, they can easily bounce off or reflect cellular signals waves and this is especially true for doubly insulated window panes and the attenuation can reach up to -4dB. Besides, the newer low emission windows that are good at keeping interiors cool or warm deflects the signals most. So, if you want to receive better cellular reception near windows, you should better open them.

Plywood, Wood And Foliage

Plywood is a very common building material found in homes and buildings; it can attenuate 3G and 4G signals by up to -6dB and it is up to -9dB for 5G network signal. Also, there can be slight variation in the numbers depending on the thickness of the plywood. Besides, the blockage can go up to -20dB if the plywood gets damp or wet. Similarly, the wood used in the home construction, flooring and furniture can reduce the signal strength; it is dependent on the thickness as well as the density of the wood. The drop in signal strength by wood varies from -5dB to -12dB and softer woods like pine attenuates less. Having said that, plants and other decorative flora that we use inside can also block the phone signals.

Brick

They are the most important material in building construction and ironically the top material that can attenuate phone signals. On top of that, the mortar that is used for binding them is very good at blocking phone signals. So the decrease in strength can be up to -28dB and it depends on the wall thickness.

So it is very important to understand the conductivity of cellular signals by building materials before building a house or shifting to an office space. If there is any drop in signal strength, then use a cell phone signal booster.
