Indoor Localization Based on the LoRa Technology

In recent years, with the development of more advanced mobile technologies and wider application requirements, many new technologies have been used for indoor localization. In this paper, we design and implement an indoor localization system based on the LoRa wireless communication technology. We proposed an improved KNN based algorithm which can greatly reduce the size of the fingerprint database. The locating system is easy to deploy, it has good accuracy and low latency. Our field study showed that it can locate a moving object or user with the accuracy of 96.72%.
