Superposing Beats: A Novel Method for High-Precision Indoor Localization

While being very successful in everyday life, GPS-based localization systems exhibit limited performance under certain circumstances, such as under trees, behind walls, and in closed rooms. In addition,they sometimes induce costs that are way too high to be acceptable for some applications. This paper addresses these problems by exploring a novel localization procedure that is based on beats and pattern recognition. Because of its low-cost properties and simple technical requirements, this system might be interesting for application areas, such as ubiquitous computing, ambient intelligence, high-precision indoor localization, and sensor networks.
