Providing indoor location awareness has been a long-established goal in ubiquitous and
pervasive computing research. In this paper we present and analyze an indoor localization …

This paper attempts to answer a question: for a given traversal area, how to quantify the
geometric impact of anchor placement on localization performance. We present a theoretical …

The angle of arrival (AoA) estimation is one of the commonly used techniques for indoor
localization. Ultrawideband (UWB) radios facilitate AoA estimation through the measurement …

This paper addresses the problem of localization through Ultra Wide-Band (UWB) devices in
the case of unavailability of a permanent infrastructure, meaning that an adhoc UWB …

Ultra wideband positioning systems typically use techniques such as two way ranging
(TWR) or time difference of arrival (TDoA) to calculate the position of mobile tags. TDoA …

We introduce Harmonium, a novel ultra wideband (UWB) RF localization architecture that
achieves decimeter-scale accuracy indoors. Harmonium strikes a balance between tag …

Ultra-wideband (UWB) is a radio technology that is usually used for indoor localization. To
complete the 3D localization task in a room, more than three UWB anchors should be …

Indoor positioning using UWB technology has gained interest due to its centimeter-level
accuracy potential. However, multipath effects and non-line-of-sight conditions cause …

Real time locating systems (RTLS) with centimeter accuracy have recently been made
available for commercial deployment by employing ultra wideband (UWB) technology …

In the last decade, wireless positioning systems have drawn a strong interest from a
research point of view, especially for indoor environments where Global Positioning …
