A low power LoRa-LoRaWan relay function with a single input, single output device

Abstract : Nowadays, more and more information is being collected, either by energy suppliers or by environmental organizations , remotely, through wireless networks. Unfortunately, some equipment is not always in areas properly covered by operators, such as metro tunnels, and is isolated. In this paper , we propose a solution for setting up equipment that will act as a relay between the isolated equipment and the oper-ator's equipment. To do this, we use LoRa technology to collect information from the isolated equipment and the Lo-RaWAN 1 protocol to send the data to the operator's gateway. Our relay can switch between pure LoRa on the one hand and LoRaWAN on the other while providing a standby function to save energy. We also present the relaying and data collection protocol as well as the results of our experiments and some corrections made in Semtech's LoRaWAN library to achieve our objective. Our solution has been tested for several months with an industrial company and an IoT operator to ensure that the solution presented in this paper worked properly.
