Exploring the Technology Powering UbiTrack’s Indoor Positioning System

In environments where GPS falls short—indoors, in warehouses, hospitals, factories—the demand for precise location tracking is huge. UbiTrack meets that demand with its high-precision real-time indoor positioning system built on advanced radio technologies and smart algorithms. Ultra-Wideband: The Core of Precision At the heart of the system is Ultra-Wideband (UWB) wireless communication. UbiTrack uses UWB operating in the 3.5 GHz–6.5 GHz range to transmit very short pulses of radio waves across a wide frequency spectrum. This enables extremely accurate distance measurement based on the “time of flight” of each radio pulse, rather than relying on signal strength. Because it uses very wide bandwidth and very short pulses, UWB is able to withstand interference and multipath reflections better than WiFi, Bluetooth, or RFID systems. For example, UbiTrack claims centimetre-level accuracy (10–30 cm), a major improvement over meter-level accuracy typical of those other systems. Anchors, Tags ...
