Abstract
In this paper, we present an asynchronous, accurate, and real-time distance measurement method using chirp signals, which is capable of accurately locating and tracking, thus forming an ad-hoc network among smartphones in an indoor (e.g., smart meeting room) environment. We then implement our proposed method on top of commercial off-the-shelf smartphones without modifying their hardware or OS kernel. Our experimental results demonstrate that it takes <1 second to conduct network-wide distance measurements and the measurement error is <10cm in at least 87% of the experiments.
