As the path loss encountered along any radio link serves as the dominant factor for characterization of propagation for the link, radio propagation models typically focus on realization of the path loss with the auxiliary task of predicting the area of coverage for a transmitter or modeling the distribution of signals over different regions.
Model Tunning is done to match the coverage distance of transmitted signal, in field and in Planning Tool for the same frequency and for similar kind of terrain and clutter.
Tuning model is crucial for proper coverage prediction matching empirical tests in field.
