How does Matlab calculate path loss?
L = fspl( R , lambda ) returns the free space path loss in decibels for a waveform with wavelength lambda propagated over a distance of R meters. The minimum value of L is zero, indicating no path loss.
What is the difference between log distance path loss model and log normal shadowing?
Log distance path loss model
The model encompasses random shadowing effects due to signal blockage by hills, trees, buildings etc. It is also referred as log normal shadowing model. for a large cell.
What is lognormal shadowing?
The log-normal distribution describes the random shadowing effects which occur over a large number of measurement locations which have the same T-R separation, but have different levels of clutter on the propagation path. This phenomenon is referred to as log -normal shadowing.
