We now have Ultra-wideband (UWB) based positioning systems which can deliver extremely precise and fast positioning information. This new technology unlocks a variety of use cases, data analytics and experiences which were previously not possible. The article will present the benefits of UWB, how it works and some real-world examples of precise indoor positioning using UWB. 

With UWB, we measure the time it takes the signal to travel from transmitter to receiver in order to calculate the distance in centimetres. This method gives much better distance information than determining distance based on signal strength with iBeacons.
