Young model is a
radio propagation model
Radio propagation is the behavior of radio waves as they travel, or are propagated, from one point to another in vacuum, or into various parts of the atmosphere.
As a form of electromagnetic radiation, like light waves, radio waves are affect ...

cellular communication systems in large cities.
Applicable to/under conditions
This model is ideal for modeling the behaviour of cellular communications in large cities with tall structures.

Mathematical formulation
The mathematical formulation for Young model is:
Where,
:''L'' =
path loss
Path loss, or path attenuation, is the reduction in power density (attenuation) of an electromagnetic wave as it propagates through space. Path loss is a major component in the analysis and design of the link budget of a telecommunication system. ...

Log-distance path loss model
The log-distance path loss model is a radio propagation model that predicts the path loss a signal encounters inside a building or densely populated areas over long distance. While the log-distance model is suitable for longer distances, the short- ...
