Abstract

LoRa is a proprietary radio communication technology exploiting license-free frequency bands, allowing low-rate information exchange over long distances with very low-power consumption. Conventional environmental monitoring sensors have the disadvantage of being in fixed positions and distributed over wide areas, thus providing measurements with spatially insufficient level of detail. Since public transport vehicles travel continuously within cities, they are ideal to house portable monitoring systems for environmental pollution and meteorological parameters. The paper presents a system to collect this information from the vehicles conveying it to a central node for processing. The communication system is realized by deploying a layer-structured, fault-resistant, multi-hop Low Power Wide Area Network (LPWAN) based on the LoRa technology. For experimental purposes, in order to simulate the behaviour of the sensors along the track of the vehicle, some measurements in a noisy urban environment have been performed to evaluate the useful communication ranges and any possible loss of information
