How UWB Ranging Works: TOF, TDOA, and Angle of Arrival Explained

Описание: Explore how Ultra-Wideband (UWB) technology enables precise distance and direction measurement using advanced ranging techniques. In this short explainer, we break down how UWB calculates time-of-flight (TOF), time-difference-of-arrival (TDOA), and angle-of-arrival (AoA) to deliver centimeter-level accuracy for indoor positioning, navigation, and smart device interaction.
