SIGNAL AND WAVES PROPAGATION
Data transmission on a physical support is the result of the propagation of a ... power of the signal are
typically carried out on a logarithmic scale.
The power is Watts in a radio transmission is therefore typically expressed in the relative value of
decibels compared to a milliwatt ... walls penetration of 16 dB per level and an attenuation exponent from 31.
Calculate the maximum transmission range for the same signal power than previously. You
