A phenomenon that affects all wireless systems. Multi-path fading is created when radio waves, arriving at a receiving antenna by different (multiple) paths, combine to reduce the strength of the signal. Multi-path fading occurs irrespective of radio signal strength and is particularly common in urban areas where radio waves do not have a line of sight path between the transmitter and the receiver.
