DescriptionThe thesis aims at establishing a proof of concept for the implementation of Ultra-wideband (UWB) technology for social distancing awareness among people in an office environment. As people get vaccinated and offices open, it is imperative to have an awareness mechanism for employee safety. UWB presents itself as a monumental upgrade over other short-range technologies in terms of accuracy and scalability. This thesis aims to highlight UWB-based devices as an effective, accurate solution for social distancing needs, particularly in high-density areas (offices, banks, etc.), required by the COVID-19 pandemic. The research used a test scenario of 2 users in an office room, where they were instructed to maintain 6 feet distance (CDC Guideline) for a working day. The results showed that the average daily contact time was 29 minutes given social awareness, self-correcting behavior, and accurate measurements from UWB devices. For enhancing the test scenario, a feedback mechanism was deployed in the office room which alerted the users of their time in contact and the behavior of the users was observed. The results showed an improvement, with the average daily contact time being 13 minutes between the users. The contact time exceeded no longer than 15 minutes (CDC Guideline) collectively between the users for a working day highlighting the intuitive sound-based feedback mechanism and the accurate UWB measurements. Finally, the conducted research shows that as UWB becomes ubiquitous, social awareness can be scaled for not only employees, but visitors as well using mobile applications. As new variants keep popping up in the world, it is imperative to have a scalable, yet flexible system and the thesis showcases such a system.
