Long Range Wide Area Network (LoRaWAN): An overview and its importance in the world of IoT

The main issues faced by the low power communication standards are its inability to communicate over a fairly long distance. This paper focuses on a fairly new connectivity protocol known as the LoRa which is gaining importance in the world of IoT for its capability to communicate over a long range while exploiting the low power advantages of the conventional LPWAN(Low Power Wide Area Network) protocol. We have discussed the LoRa standard here along with its advantages over other protocols like Zigbee, Bluetooth, Z-wave which till now are reigning the low power wireless connectivity domain.

A Survey of LoRaWAN for IoT: From Technology to Application

Sensors, 2018

LoRaWAN is one of the low power wide area network (LPWAN) technologies that have received significant attention by the research community in the recent years. It offers low-power, low-data rate communication over a wide range of covered area. In the past years, the number of publications regarding LoRa and LoRaWAN has grown tremendously. This paper provides an overview of research work that has been published from 2015 to September 2018 and that is accessible via Google Scholar and IEEE Explore databases. First, a detailed description of the technology is given, including existing security and reliability mechanisms. This literature overview is structured by categorizing papers according to the following topics: (i) physical layer aspects; (ii) network layer aspects; (iii) possible improvements; and (iv) extensions to the standard. Finally, a strengths, weaknesses, opportunities and threats (SWOT) analysis is presented along with the challenges that LoRa and LoRaWAN still face.

A Study of LoRa: Long Range & Low Power Networks for the Internet of Things

LoRa is a long-range, low-power, low-bitrate, wireless telecommunications system, promoted as an infrastructure solution for the Internet of Things: end-devices use LoRa across a single wireless hop to communicate to gateway(s), connected to the Internet and which act as transparent bridges and relay messages between these end-devices and a central network server. This paper provides an overview of LoRa and an in-depth analysis of its functional components. The physical and data link layer performance is evaluated by field tests and simulations. Based on the analysis and evaluations, some possible solutions for performance enhancements are proposed.

A Survey on Devices Exploiting Lora Communication

Acta Marisiensis. Seria Technologica, 2020

Information and Communication Technologies (ICT) have experienced a large application in many fields, such as smart homes, health monitoring, environmental monitoring, and a great number of studies is present in literature. In particular, it is expected that the Internet of Things (IoT) will become increasingly pervasive in everyday life. Among different technologies, devices based on Long Range (LoRa) and LoRaWAN stand out due to their relative low cost, low power consumption and large cover range. In this survey, recent papers investigating applications of LoRa modules have been selected. The different use-cases are presented with a comparison between communication parameters and results obtained.
