Overview of indoor positioning system technologies

Constant changes in the field of indoor positioning systems (IPS) dictate that we keep up with new and developing trends and technologies. With improving accuracy, IPS found widespread application in commercial environments, such as asset or personnel tracking. However, it is yet to be established in the everyday personal usage applications. In this paper, we present a technological overview and classification of the most relevant IPS technologies. We compare technologies based on their cost, accuracy, performance and complexity. Hybrid approaches are also investigated as a way to overcome limitations of specific IPS technologies. The paper is mostly focused on IPS technologies that can be used in personal applications, using pocket-sized devices (e.g. smartphone).
