Analysis of the Susceptibility of the LoRa Communication Protocol in the Railway Electromagnetic Environment

Abstract

In the context of the digital transformation of railway transportation systems, railway operators investigate the potentialities of the IoT (Internet of Things) in order to optimize the maintenance operations on the vehicles and the infrastructures. One of the interest is to use IoT communication solutions in order to centralize the data measured by the different sensors distributed everywhere along the railway infrastructures and on board the trains. In this perspective, different communication protocols could be employed. This paper deals specifically with the LoRa communication protocol and analyses its susceptibility in the presence of railway electromagnetic interferences. This paper presents a susceptibility analysis of the LoRa communications in the presence of transient EM interferences representative of the electromagnetic interferences produced by the sliding catenary-pantograph contact.
