Where:

A_p = Power Attenuation, or Power drop of signal transmission due to over long distances. Attenuation is measuring the loss of signal from the input terminal port to the output terminal port. Attenuation is the opposite of amplifier which measuring the signal gain from the input terminal port to the output terminal port.

P_s= Signal Power at the transmitter end (source)

P_d = Signal Power at the receiving end (destination)
