What is the propagation model? Deterministic models (also called geometrical) models estimate the field strength (or signal power) directly from the path profile (profile of the terrain between the transmitter and the receiver). These methods adjust the terrain elevation to take account of the earth’s curvature.
What is the significance of propagation model in wireless communication? A radio propagation model describes the behavior of the signal while it is transmitted from the transmitter towards the receiver. It gives a relation between the distance of transmitter & receiver and the path loss. From this relation, one can get an idea about the allowed path loss and the maximum cell range.
What is propagation model in cellular network? A reliable propagation model is one which calculates the path loss with small standard deviation. This will, hence, help network engineers and planners to optimise the cell coverage size and to use the correct transmitted powers. Suitable models must be chosen for prediction.
What are the two types of propagation model? The two basic propagation models (Free-Space and Plane Earth Loss) have all the mechanisms which are encountered in macrocell prediction. Many researchers use these models and predict the total signal loss.
