Analysis of the visibility and signal strength of the LoRaWAN network in an urbanized area – a case study of the Bielany campus at the Nicolaus Copernicus University in Toruń

Abstract In order to assess or determine the overall quality of surrounding geographical environment, it is necessary measure selected factors that directly indirectly affect its condition. The aspects be monitored include i.a. air pollution levels, surface water purity, soil erosion rates, as well night sky light pollution, a phenomenon increasingly often observed with unaided eye. To collect data on brightness regular basis, remote measuring device was designed and constructed using specialised electronic components, wireless communication, programming code, high-sensitivity digital logger custom-made programme code. LPWAN networks, including LoRa technology, were developed support number mobile devices where long operation priority. potential use plan target locations network access gates (gateways) deployment for collection environmental data, tests signal coverage visibility, measurements strength, carried out in selected, compact part city Toruń. paper presents results research visibility built-up area, such university campus, antennas two different lengths. obtained can used design distributed measurement networks areas varying density buildings.
