Mean path loss

Web“Path loss” is the signal loss from the output of the transmitter to the input of the receiver, due to the propagation of the signal through space, usually expressed in dB Path losses … WebTypically, the energy of a signal fades with distance, which is referred to as a path loss in wireless networks. Conversely, in wired networks the existence of a wired path between the sender or transmitter and the receiver determines the correct reception of data. In a wireless network one has to take other factors into account (e.g. the ...
