InfraRad : A Radio-Optical Beaconing Approach for Accurate Indoor Localization

Accurate indoor localization is a big driving force for many human-centric applications. Over the years, various approaches have been exercised, but still not converged to a common technique ready for commercial usage everywhere due to the energy, size or cost constraints. We present the InfraRad system that uses a hybrid radio-optical technique to achieve high localization accuracy with low energy consumption.
