What Blocks cell phone signals?

Cell phone call signals have the right to be blocked a small or a lot relying on the kind of materials used in building and construction of the building. Products that perform not conduct electrical power like wood, drywall, plastics, and glass will certainly impede a to move signal, however not block it.

Each of these has actually an result on even if it is the cell phone signal renders it right into your residence office. Include them all together in the building and construction of your home and also you will view all the ways structure materials block cell phone signals.


Solid timber in her walls, ceilings, doors and even furnishings minimize signal by -5dB come -12dB. Plywood is thinner and can only minimize the signal by -4dB and also -6dB.


You could think that signals deserve to pass right through glass, yet clear glass actually refracts the signal bring about a lose of about -4dB. If you have tinted glass design for energy efficiency and also privacy (low-e glass), this price of lose is a staggering -24dB come -40dB.

Insulation and also Drywall

The an ext layers of structure materials, the much more signal is blocked. Fiberglass is quite porous in ~ -2dB, but include drywall and the ns is -4dB.

In the Office

Office buildings add an ext robust and longer-lasting products such as metal, brick and also concrete. We already talked around glass, for this reason imagine the deluxe glass materials in commercial construction as well. These are even better at prevent signals.

Classic homes and also old buildings with a the majority of character are built of brick. Suppose loss that -8dB and -28dB.

What carry out These number Mean?

We have actually a entirety article about dBm but, in short: mobile signals operate at frequencies in between -50dBm and -120dBm. The lower end of the spectrum at -50dBm is basically identical to 4 bars on your cell phone. -120dBm is usually no signal. If you measure the mobile signal outside and also the frequency claims -60dBm, it is pretty good. Now you go in a structure made the wood and also insulation, you are shedding several db. Relying on furniture and also how numerous walls you space behind, the signal strength can have diminished to -80dBm or less.

How execute I Get better Cell Signal?
