“…As a result, the real‐time locating system (RTLS) based on ultra‐wideband (UWB) was the most adequate technology for the purpose of this research 49,51‐55 . Based on both the comparisons conducted by other authors 56 and our analysis and available resources, a Decawave ® 57 equipment was chosen as there were experimental precedents in several spaces and situations 58‐65 . This equipment is an ultra‐wideband network constituted by fixed nodes (anchors) and moving nodes (tags).…”

One of the main modes of transmission and propagation of COVID‐19 (SARS‐CoV‐2) is the direct contact with respiratory droplets transmitted among individuals at a certain distance. There are indoor spaces, such as dwellings, in which the transmission risk is high. This research aims to record and analyze risk close contacts in this scope, experimentally assessing the effectiveness of using electronic proximity warning sound devices or systems. For this purpose, the methodology is based on monitoring the location of the occupants of a dwelling. Then, the days in which a proximity warning sound system is installed and activated are compared to the days in which the system is not activated. The results stressed the significant reduction of time and number of close contacts among individuals when the warning was activated. Regarding the relation between the number and the duration of close contacts, together with the reductions mentioned, the possibility of making certain predictions based on the distributions obtained is proved. All this contributes to the progress in the prevention of COVID‐19 transmission because of close contacts in dwellings.
