A Comparative Analysis of LoRa and LoRaWAN in the Presence of Jammers and Transient Interference

There is a lack of studies about the susceptibility of LoRa networks to specific interference sources such as broadband jammers and the train catenary, which produces transient interference in a railway environment. In this paper, we investigate this topic by separately analyzing the proprietary LoRa physical layer and the open medium access control layer. Such an approach allows us to decompose the interference effects into two elements: the signal integrity effects at the physical layer and the counter measures of the LoRaWAN protocol.
