Over the coming decades, high-definition situationally-aware networks have the potential to
create revolutionary applications in the social, scientific, commercial, and military sectors …

There are many challenges in building an ultra-wideband (UWB) indoor local positioning
system for high-accuracy applications. These challenges include reduced accuracy due to …

Ultra-wide-band (UWB) signals are suitable for underlay communications, over a frequency
band where, possibly, other systems are active. Such coexistence of UWB and other …

The possibility to accurately localize tags by using wireless techniques is of great
importance for several emerging applications in the Internet of Things. Precise ranging can …

Time-of-Arrival (ToA) estimation becomes extremely challenging for ultra-wideband ranging
systems in dense multipath environment with multiuser interference. In this paper, we …

We demonstrate that an interferer with malicious intentions can significantly degrade the
performance of impulseradio (IR) ranging. The cicada attack we have developed can …

To provide high ranging precision in multipath environments, a ranging protocol should find
the first arriving path, rather than the strongest path. We demonstrate a new attack vector that …

In this paper, we describe a rotating anchor-based positioning method using time of arrival
(TOA) measurements to obtain the relative positional relationship between two locators …

Reliable time of arrival (ToA) estimation in dense multipath (DM) environments is a difficult
task, especially when strong interference is present. The increasing number of multiple …

Roundtrip time-of-arrival (ToA) measurements employing ultra-wideband (UWB) signals can
provide high-precision ranging information. However, the accuracy is degraded by multiuser …
