LoRa in Multipath: Theory vs. Experiment
Recently, we came across this great paper (link, free PDF) about modeling the impact of multipath on LoRa modulation. Specifically, it models Rayleigh flat fading, which is observed in urban and indoor use-cases. We had just finished testing LoRaWAN vs. Haystack’s LoRa XR2 in an environment with heavy multipath interference (an airport parking garage). The …
