The IoT requires that objects can communicate between themselves and with the wider world. For certain use cases, objects will need to be independant of both a fixed power source and a wired network connection. They must both run for months or years on batteries, and wirelessly communicate bi-directionally over distances ranging from 100s to 1000s of metres. Until recently, solutions that enabled both these criteria were rare and proprietary. The LoRa radio technology and its associated WAN MAC layer protocol LoRaWAN provides a standardised and widely adopted method for objects to embed a low power, long range communication solution. The presentation will cover the basic principles of the technology, its advantages and its limitations, and an example of its operation in a specific application : use of autonomous objects for indoor localisation.
