Recently published research (July 2019) has described a model for Bit Error Rate (BER) analysis of the LoRa PHY over a Rayleigh flat fading channel. Rayleigh flat fading channels are observable in environments where there’s a lot of multipath interference (e.g. dense urban, indoor, etc).
The LoRa PHY experiences significant degradation of sensitivity in Raleigh flat fading channels
Experimentation in an environment exhibiting Raleigh flat fading validates the model from the research.
Haystack XR2 encoding for LoRa was observed to yield roughly 30 dB gain to Packet Error Rate (PER) vs. default LoRaWAN encoding, in said experiment.
Haystack XR2 encoding for LoRa can yield enormous gains to efficiency, Quality of Service (QoS), and channel density for LoRa deployments in dense urban, indoor, or other environments where multipath dominates.
