(dB), which is ten times the logarithm of the signal power at a particular
input divided by the signal power at an output of a specified medium.
For example, an office wall (i.e., medium) that changes the propagation
of an RF signal from a power level of 200 milliwatts (the input) to 100
milliwatts (the output) represents 3 dB of attenuation. The following
provides some examples of the attenuation values of common office
construction:
Plasterboard wall: 3dB
Glass wall with metal frame: 6dB
Cinder block wall: 4dB
Office window: 3dB
Metal door: 6dB
Metal door in brick wall: 12.4dB
Other factors that will reduce range and affect coverage area include
concrete fiberboard walls, aluminum siding, pipes and electrical wiring,
microwave ovens, and cordless phones.
