Abstract:

IoT deployments require long-range wireless communications, especially in

urban and metropolitan areas. LoRa is one of the most promising technologies in this

context because of its simplicity and flexibility. In fact, the deployment of LoRa networks

in dense IoT scenarios must achieve two main objectives: effective communication between

a large number of devices and resilience to dynamic channel conditions due to demanding

environments (for example, the presence of many buildings). This paper reviews and shows

a LoRa network deployed within our team that will be deployed in our building. This work

is part of the regional project "E-Water Efficiency", where we are working to improve the

robustness of environmental sensor networks. We are implementing around thirty sensors

on STM32 cards that are used to transmit packets to a gateway, then will be sent back to the

cloud for processing at the final destination. In fact, the work environment will strongly

influence the design of the network. But once the network is operational, we can implement

coding algorithms to improve robustness, such as: non-rate coding, network coding,

cooperative relay communication, rank metric coding, etc. This paper presents pedagogical

efforts made for the practical implementation of such a network.
