COVID-19 is driving demand for new services based on indoor positioning technologies related to location capacity counting and proximity reporting. This kind of data can be analyzed over time for better decision-making and management regarding a facility. People may collaborate by using a particular app on their smartphone or by carrying a custom device, but research must also deal with the issue that people may not collaborate in downloading an app on their smartphones or in using wearables. These challenging services will be useful and much needed by private sites such as industrial facilities and offices as well as public sites such as universities, hospitals, malls, airports or railway stations. Some solutions are based on the smartphone, using Bluetooth Low Energy or Wi-Fi combined with IMU sensors, or based on custom devices such as a bracelet or a wristband using Ultra-Wideband (UWB) or Bluetooth Low Energy. In addition, IoT solutions could potentially allow the deployment of these services.
This Special Issue aims to collect high-quality research papers and review articles focusing on recent advances in occupancy and social distance monitoring based on indoor positioning systems. Original, high-quality contributions that have not been published before and are not currently under review by other journals or conferences are sought.
