Large-scale path loss is the gradual decrease in the local average received signal as a mobile moves away from the transmitter over larger distances. The average received signal power decreases logarithmically with distance, whether in outdoor or indoor radio channels. The average large-scale path loss for an arbitrary T-R separation is expressed as a function of distance (d) by using a path loss exponent, (n). Large scale-fading represents the average signal-power attenuation or path loss due to motion over large areas. It is impacted by terrain configuration between the transmitter and receiver. Typical values of path–loss exponents range between 1.5 and 5.
