IoT devices and applications based on LoRa/LoRaWAN

TLDR

IoT has transformed the Internet by enabling connected objects, driving demand for energy‑efficient, long‑range sensor nodes that led to LPWAN technologies such as LoRa. The paper surveys LoRa/LoRaWAN IoT devices and applications to assess current device usage and promote LoRa as a viable long‑range, distributed communication technology. The authors conduct a survey of LoRa/LoRaWAN devices and applications, reviewing device parameter settings and experimental results. The survey identifies key device parameter settings and summarizes experimental outcomes for LoRa/LoRaWAN IoT devices.

Abstract

Internet of Things (IoT) has revolutionized the traditional Internet where only human-centric services were offered. It has enabled objects to have the ability to connect and communicate through the Internet. IoT has several applications such as smart water management systems. However, they require high energy-efficient sensor nodes that are able to communicate across long distance. This motivates the development of many Low-Power Wide Area Networks (LPWAN) technologies, such as LoRa, to fulfill these requirements. Therefore, in this paper, we survey IoT devices and different applications based on LoRa and LoRaWAN in order understand the current stream of devices used. The objective is to contribute toward the realization of LoRa as a viable communication technology for applications that needs long-range links and deployed in a distributed manner. We highlighted the device parameter settings and the output of each experiment surveyed.
