Recent trends and advances in UWB positioning

Abstract

Since the ruling of the Federal Communications Commission (FCC) in the United States to open up the spectrum from 3.1-10.6 GHz for ultra wideband (UWB) applications in 2002, interest in the use of UWB for localization outside of military applications has skyrocketed. The multi-purpose nature of UWB for localization and also high or low data rate communication make it robust and attractive in many indoor applications including wireless sensor networks, medical body area networks (BANs), surgical navigation, etc. A push towards integrating UWB with global positioning systems (GPS), wireless local area networks (WLANs), Wi-Fi, and inertial measurement units (IMUs) help to mitigate localization errors with redundancy and increase interoperability with existing technologies. A look at the current trends both in the research community and industry highlight future applications of UWB positioning and the technologies which will serve as the building blocks in these systems.

A 5.6-GHz UWB Position Measurement System

“…This work describes results obtained with a positioning system entirely realized using COTS components to reduce complexity and implementation costs. It proposes a simple architecture that extends the state of the art in this field [14] by experimentally proving that accurate positioning can be achieved by avoiding the need for complex and expensive solutions. In fact, recently published positioning methods rely on the synchronization of anchors or on the usage of hybrid direction-of-arrival/timeof-arrival approaches or on the usage of complex high-speed correlators and digital processing, as published in [15]- [18].…”

Survey of Energy Efficient Tracking and Localization Techniques in Buildings Using Optical and Wireless Communication Media

“…-Cellular-based using the mobile cellular network to estimate indoor positioning, when considering that the building is covered by several LBSs [54]. -Ultra Wide Band(UWB)-based using ultra-short pulses with a low duty cycle permitting an accurate determination of the Time of Arrival [34]. -WLAN-based using IEEE 802.11 for positioning by e.g., adding a location server [5].…”

Numerical and experimental investigation of TDOA-based positioning system by ultra-wideband impulse radio

“…The positioning error is gradually increased as moving away from the Examples of error range calculated from the simulation are shown in Figs. 5(a) and 5(b), which are the cases that TN is placed at (3,3) and at (5,5), respectively. In Figs.…”

“…The positioning accuracy as high as centimeters is a distinctive advantage of UWB-IR system over other radio positioning systems, e.g., the GPS and WLAN technologies. Hence, widespread application of UWB-IR positioning system has been eagerly investigated both in industry and academia [3].…”
