Abstract

In an embodiment an ultra-wideband indoor real-time location system for determining positions of mobile tag devices within a localizing area includes a plurality of UWB signal transmitters located at preset positions and defining the localizing area, wherein the UWB signal transmitters are configured to operate with synchronized clocks and transmit UWB signals based on a UWB frame format, and wherein the UWB frame format includes unique information content for the UWB signal transmitter and at least one mobile tag device comprising a signal reception unit configured to receive the UWB signals, a time detection unit configured to derive respective arrival time points for the received UWB signals, an identification unit configured to derive the unique information content from the received UWB signals and a control unit configured to process the unique information content and the arrival time points for at least a subset of the UWB signal transmitters in a localizing algorithm to derive a position of the mobile tag device with respect to the subset of the UWB signal transmitters.
