4.1.3 Path Loss Considerations
The path loss is the amount of attenuation the radio signal undergoes between the two ends of the link. The path
loss is the sum of the attenuation of the path if there were no obstacles in the way (Free Space Path Loss), the
attenuation caused by obstacles (Excess Path Loss) and a margin to allow for possible fading of the radio signal
(Fade Margin).
