Comparision of deterministic and empirical Prediction Models
Find the best
propagation model for your needs
Introduction
WinProp offers several empirical and deterministic propagation models
for the prediction in different scenarios, such as rural, urban and
indoor environments.
Comparison
of Prediction Models
The following table shows a comparison between severals computation
methods, available in WinProp prediciton models. With knowing your
requirements, you can find the best prediction model for your
application.
