Detailed explanation-1: -Explanation: Small scale propagation model is also called fading model. Fading model characterize the rapid fluctuations of the received signal strength over very short distance of a few wavelengths or short time duration.
Detailed explanation-2: -On the other hand, propagation models. that characterize the rapid fluctuations of the received signal strength over very. short travel distances (a few wavelengths) or short time durations (on the order of seconds) are called small-scale or fading models.
Detailed explanation-3: -The free space propagation model is used to predict received signal strength, when unobstructed line-of-sight path between transmitter & receiver.
Detailed explanation-4: -Free Space Propagation Model. The free space propagation model is used to predict received signal strength when the transmitter and receiver have a clear, unobstructed line-of-sight path between them Friis 1946.
Detailed explanation-5: -Line of sight (LOS) propagation. Ground wave propagation. Sky wave propagation.
