Radio Frequency Identification (RFID) has become a key enabler for the Industrial Internet of
Things (IIoT). By taking advantage of the backscattered radio waves, the identity and …

In this paper, we give an overview of spatial identification (determining position and velocity)
of modulated backscatter UHF RFID tags using RF phase information. We describe three …

Indoor positioning is a key technology that enables the development of various smart and
autonomous indoor applications. In recent years, wireless device is considered a promising …

Reading ranges are being extended in the wake of recent advances in UHF radio frequency
identification (RFID) systems, and with the advent of larger reading ranges, tag localization …

In this paper a method for holographic localization of passive UHF-RFID transponders is
presented. It is shown how persons or devices that are equipped with a RFID reader and …

This paper introduces a two-dimensional localization system for passive UHF RFID
transponders based on phase-of-arrival evaluation of the backscattered tag signal. A …

Radiofrequency identification (RFID) has penetrated logistics, manufacturing, production,
ticketing, access control, baggage tagging and various other areas of our daily life [1]. RFID …

The paper gives an overview of phase based ranging techniques, focusing on the phase
difference of arrival method measured in frequency domain (FD-PDoA). After a theoretical …

Short-distance, millimeter-level ranging based on backscatter RF tags remains a challenge
today. We propose a composite dual-frequency continuous-wave and continuous-wave …

In this paper the impact of the signal bandwidth on the performance of frequency modulated
continuous wave (FMCW) radar based ranging to ultra high frequency (UHF) radio …
