“…objects in Global Positioning System (GPS)-denied areas. UWB promises localization with centimeter, or even subcentimeter [8] accuracy, while consuming milliwatts of power and being computationally lightweight [7] -two prerequisites for IoT devices. So far, UWB could only provide a scalar distance l between two ranging agents, ignoring the direction of the incoming signals.…”

Accurate and low-power indoor localization is becoming more and more of a necessity to empower novel consumer and industrial applications. In this field, the most promising technology is based on Ultra-Wideband (UWB) modulation; however, current UWB positioning systems do not reach centimeter accuracy in general deployments due to multi-path and nonisotropic antennas, still necessitating several fixed anchors to estimate an object's position in space. This paper presents an in-depth study and assessment of Angle of Arrival (AoA) UWB measurements using a compact, low-power solution integrating a novel commercial module with Phase Difference of Arrival (PDoA) estimation as integrated feature. Results demonstrate the possibility of reaching centimeter distance precision and 2.4°average angular accuracy in many operative conditions, e.g., in a 90°range around the center. Moreover, integrating the channel impulse response, the phase differential of arrival, and the point-to-point distance, an error correction model is discussed to compensate for reflections, multi-paths, and frontback ambiguity.

UWB is computationally lightweight and allows to localize objects with centimeter, or even sub-centimeter [7] accuracy, while being energyefficient [8]. Especially, Decawave's DWM1000 is widely used in many research and commercial solutions [6], [7], [9].…”

Indoor localization and context-awareness are becoming two of the key technologies to for a large variety of applications. Real-time locating systems with centimeter accuracy and low power consumption have recently been made available by employing the Ultra WideBand (UWB) technology. Since 2015, Decawave has produced commercial UWB integrated circuits, exploiting time-of-flight measurement techniques to estimate the distance between two agents. This work presents a performance study between two Decawave transceivers, the DW1000 and the new DW3000 released in 2020. The testing space includes areas under line-of-sight and diverse non-line-of-sight conditions caused by the reflection of the UWB radio signals across various obstacles. Finally, we analyze the power consumption in distinct configurations, providing a comparison between the two devices. Results show that the two have similar precision in measurement ranges above one meter, while the DW3000 performs, on average, 33.2% better considering shorter distances. Moreover, the new transceiver features reduced power consumption by almost 50% during real-time measurements reaching an average value of 55 mW.
