The Problem

Dense scenarios, in the order of thousands of devices, pose a high stress on location systems due to the noise generated by the moving objects and the multipath signal propagation they imply. This problem gets even more critical as the COVID-19 spreads along the world and requires new solutions to help the Healthcare institutions get accurate and precise information to locate users and contacts in order to track the spread of the disease.
The use of Ultra Wide Band (UWB) solution combined with the paradigm change that reverse TDOA brings (offloading the calculation to the Tags) solves the problem, reaching an accurate position (up to 10 cm) even on dense user scenarios. The Anchors blink to mobile devices (Tags) who compute their own location. The key element is the Anchor synchronization to ensure that their blink doesn’t collide on the access medium. i2CAT solved this key issue with a novel hardware design of clock and synchronization module that distributes the signal to the anchors via UTP cable.
