Rural Prediction Models

Comparison

Introduction

 

In the following, comparisons between rural 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 campagins) can be found on the accuracy page.

Scenario 1: Area of Hong Kong (China)

Size of predication area 5.3 km x 7.6 km = 40.3 kmē
Resolution 20 m
Pixels 100,000
Heights of topography 11 to 650 meters

 

 

Rural Dominant Path Model

Hata Okumura Model with

Knife Edge Diffraction Extension

Hata Okumura Model

 
Accuracy:
(close to Tx)
high good ok in LOS areas
Accuracy:
(far away from Tx)
still high good if no rapid change of topography limited in NLOS areas

Computation

Time

some minutes less than one minute less than one minute

 

 

Scenario 2: Albis (Switzerland)

Size of predication area 7.8 km x 7.8 km = 60.8 kmē
Resolution 20 m
Pixels 152,000
Heights of topography 530 to 860 meters
