TLDR
The LoRa technology is a long range low power technology that addresses the needs of a battery operated embedded device and the advantages of LoRa over the existing technologies used in IoT.Abstract:
IoT is gaining high popularity in today's world. Embedded systems have become a major part of our lives. People are able to control, monitor, and do a lot more from remote distance. This is done by connecting various objects reducing physical distance. IoT is the connectivity of various objects with network connectivity. Many a times these systems are battery operated and need a high battery backup. These systems require a technology that consumes less power and also covers long distances. But many technologies such as Zig-Bee, Wi-Fi, Bluetooth popularly used at present consumes high power and is not suitable for battery operated systems. LoRa is a new found technology that is emerging rapidly. The LoRa technology addresses these needs of a battery operated embedded device. The LoRa technology is a long range low power technology. This paper discuses about the advantages of LoRa over the existing technologies used in IoT. It also discusses the features of LoRa. LoRa WAn(Long Range Wide Area Network) is an open grade secure standard for the IoT connectivity. The LoRa alliance is an open non profitable group that shares their experience to drive LoRa.read more
