However, designing a proper beacon installation requires knowledge of the possible sources of interference in the target environment. While theoretically beacon signal strength should decay linearly with log distance, on-site measurements usually reveal that noise from objects such as Wi-Fi networks operating in the vicinity significantly alters the expected signal range. The paper presents a novel mobile Geographic Information System for measurement, mapping and local as well as online storage of Bluetooth beacon signal strength in semireal time. For the purpose of on-site geovisual analysis of the signal, the application integrates a dedicated interpolation algorithm optimized for low-power devices. The paper discusses the performance and quality of the mapping algorithms in several different test environments.}, type={Artykuły / Articles}, title={Dynamic Signal Strength Mapping and Analysis by Means of Mobile Geographic Information System}, URL={http://rhis.czasopisma.pan.pl/Content/106324/PDF/10.1515-mms-2017-0057-paper%2002.pdf}, doi={10.1515/mms-2017-0057}, keywords={beacon, mapping, GIS, geovisual analytics}, }
