Evaluation of Energy Consumption in Different LoRaWAN End Device Classes

Abstract

This paper presents a comparison of the power consumption of different LoRaWAN classes (A, B, and C). It also describes the design and implementation of a LoRaWAN GNSS tracker based on the STM32WLE5 microcontroller (in the form of the Seeed Studio Wio-E5 module), which integrates the LoRa transceiver and offers convenient approach instead of the usual need for separate microcontroller and transceiver. The tracker also serves as a platform for the power consumption measurements and analysis.
