Indoor Prediction Models

Comparison

 

 

Introduction

 
In the following, comparisons between urban prediction models for several scenarios are shown.

 

For the comparison, the following predictions models were used: A detailed comparison of these prediction models (also to several measurement campaigns) can be found on the accuracy page.
