Indoor Positioning with Ultra-wideband

What is Ultra-wideband and how can it be used for Indoor Positioning?

Ultra-wideband (UWB) is a broadband signal which can be used for indoor positioning. UWB is mostly used in industry environments where the positioning accuracy must be 10-30 cm. The position is determined by a transit time method (Time of Flight, ToF). The radiated light between the object and at least 3 Anchors (receivers) is sufficient to calculate the exact position. A tag is attached to the asset and transmits the required data to the permanently installed Anchors. Indoor positioning with Ultra-wideband can be realized as a server-based or client-based installation.
