Simulation and Modelling of LoRa and Sigfox Low Power Wide Area Network Technologies

Abstract

during this decade, there has been a huge expansion in the number of low-power Internet connected devices. The Low Power Wide Area Network (LPWAN); because of its low-cost communication ability and long-range, is considered the future wireless communication standard for Internet of Things (IoT). Although IoT is gaining more popularity, the suitability of LPWAN technologies for IoT devices is still under investigation. In this paper we develop a simulation focusing on LoRa and Sigfox to evaluate each individual LPWAN technology. We evaluate the influenceof the number of devices on LoRa and Sigfox performance by measuring collision, packet error rate and spectrum under different values of the number of IoT devices. Initial simulation results show that Sigfox has less collisions and packet error rate compared to LoRa.
