Signal Attenuation through Foliage Estimator (SAFE)

TL;DR

SAFE is an open-source RF propagation model that improves path loss predictions in foliage environments by combining the ITU-R P.1812-6 model with physics-based RET modeling and high-resolution terrain data.

Contribution

It introduces an open-source tool that integrates multiple models and high-resolution data for more accurate foliage path loss estimation.

Findings

Enhanced prediction accuracy in foliage environments.

Open-source availability facilitates wider adoption.

Combines empirical and physics-based modeling approaches.

Abstract

The SAFE tool is an open-source Radio Frequency (RF) propagation model designed for path loss predictions in foliage-dominant environments. It utilizes the ITU-R P.1812-6 model as its backbone, enhances predictions with the physics-based Radiative Energy Transfer (RET) model and makes use of high-resolution terrain and clutter elevation datasets
