A Study on LoRa Signal Propagation Models in Urban Environments for Large-scale Networks Deployment

The development of Low-Power Wide-Area Networks is challenging in urban areas due to the terrain elevation changes, clutter losses or dense vegetation regions that attenuate the radio signals. To provide accurate coverage estimation, signal propagation models that integrate losses caused by reflec...
