Design and Deployment of an IoT Network Based on LoRa

In this paper, we present a student project dedicated to the Internet of Things (IoT). The objective is to design and deploy a network of connected devices using LoRa technology to monitor the 20.000 m2 of our engineering school, ENSEIRB-MATMECA. Supervising the school using connected device came to the requirements to control our energy consumption. We choose a deployment in LoRa technology (open model compared to Sigfox) in order to master the deployment of the network from the beginning to the end. Modtronix LoRa modules inAIR9 and inAIR4 operating respectively in the 868MHz and 433MHz frequency bands were used as key components. There are 3 main blocks: sensor, gateway and server. All three are fully designed in the scope of this project by a team composed of 18 students.
