International audienceWe present the LoRaFFEC protocol, which proposes fragmentation and Forward Error Correction to the LoRaWAN TM standard. The idea of this new mechanisms is to make the applications worldwide compatible with all LoRaWAN TM deployments, with a similar sensitivity to packet losses. With LoRaFFEC, any payload length can benefit from better Data Delivery Rate (DDR) for a wide range of channel-level packet losses
