High Reliability in LoRaWAN [PDF]

open access: yes2020 IEEE 31st Annual International Symposium on Personal, Indoor and Mobile Radio Communications, 2020
In this paper, we propose to optimize the LoRaWAN® Adaptive Data Rate algorithm in case an inter-packet error correction scheme is available. We adjust its parameters based on analysis of the LoRa channel, supported by real-world traffic traces. The resulting protocol provides high reliability even over low quality channels with comparable Time on Air ...
