Energy Efficiency Comparison LPWANs: LoRaWAN vs Sigfox

This article compares the energy efficiency of two radio technologies LoRaWAN and Sigfox for Internet of Things. The researched technologies are popular and quite close in terms of consumer parameters, so the user often faces the choice of which one to use for his use case. For this, a typical decision was made (use case), consisting of a sensor, MCU, and modem. Considering that, LoRaWAN originally has more advanced settings and flexible customizable parameters, within the framework of this investigation, the range of their changes was chosen as close as possible to Sigfox. In conclusion, a comparative analysis of the energy efficiency of these two technologies for various payloads and the number of messages per day was obtained, and recommendations were made for their optimization. The simulation results obtained are in good agreement with the experimental results obtained by other authors.
