Machine learning models show improved path loss prediction for LPWANs

Researchers have conducted a systematic analysis of machine learning models for predicting path loss in Low Power Wide Area Networks (LPWANs), specifically focusing on LoRa technology. The study employed Random Forest models utilizing LiDAR-derived terrain features and k-Nearest Neighbors models with coordinate data, comparing their performance against traditional empirical models. Results indicate that the machine learning approaches consistently outperformed baseline models, achieving lower Root Mean Square Error (RMSE) values, particularly for within-deployment interpolation.
