ABSTRACT
We describe the design, implementation, and evaluation of an indoor positioning system based on resonant magnetic coupling. The system has an accuracy of less than 1 m2 and, because of the underlying physical principle, is robust with respect to disturbances such as people moving around or changes in room configuration. It consists of 16x16x16 cm transmitter coils, each able to cover an area of up to 50 m2, and provides location information to an arbitrary number of mobile receivers with an update rate of up to 30Hz. We evaluate the actual accuracy of the positioning with a robotic arm and show quantitatively that even large metallic objects have little effect on the signal. We then present an elaborate study of the performance of our system for the recognition of abstract locations such as "at the table", "in front of a cabinet". It comprises four different sites with a total of 100 individual locations some as little as 50 cm apart.

Spinning beacons for precise indoor localization
SenSys '08: Proceedings of the 6th ACM conference on Embedded network sensor systemsThis work proposes the novel use of spinning beacons for precise indoor localization. The proposed "SpinLoc" (Spinning Indoor Localization) system uses "spinning" (i.e., rotating) beacons to create and detect predictable and highly distinguishable ...
Indoor localization using multi-range beaconing: poster
MobiHoc '16: Proceedings of the 17th ACM International Symposium on Mobile Ad Hoc Networking and ComputingThe increasing importance of location-aware computing and context-dependent services have led to a growing interest in low-cost indoor positioning with sub-meter accuracy. Bluetooth positioning has received increasing attention from both academia and ...
Accurate and Low-cost Mobile Indoor Localization with 2-D Magnetic Fingerprints
CrowdSenSys '17: Proceedings of the First ACM Workshop on Mobile Crowdsensing Systems and ApplicationsIndoor localization is particularly valuable in many indoor application scenarios, such as shopping malls and airports. An indoor localization system on smartphones should be low-power as well as accurate. In this paper, we present Turnin - a completely ...
