The TC4TL (Too Close For Too Long) challenge is aimed towards designing an effective proximity sensing algorithm that can accurately provide exposure notifications. In this paper,we describe our approach to model sensor and other
device level data to estimate distance between two phones. We alsopresent our research and data analysis on the TC4TL challengeand discuss various limitations associated with the task, and thedataset used for this purpose.
