Abstract
We propose a system for monitoring social distance on university campuses to prevent the spread of COVID-19 infections. In our proposed system, mobile nodes are distributed to students as permits for entering the campus. Distances between students are measured by periodically sending and receiving BLE advertising packets between nodes. Locations of nodes on the campus can be roughly estimated by using signals from the university Wi-Fi network. Information collected by mobile nodes is sent to a monitoring server. We partially implement the proposed system using an ESP32-based micro-computer module as a mobile node. We evaluate fundamental performance of the implemented system, especially regarding BLE communication between nodes.
