What is log distance path loss model and log normal shadowing phenomenon?

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.

What is path loss Modelling?

Path loss propagation models is an experimental mathematical formula for characterizing the propagation of radio waves as a distance function between the antennas of transmitter and receiver. These models are designed based on a large dataset collected from specific environments.

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.
