Extension of an SDR UHF RFID Testbed for MIMO and Monostatic Time of Flight Based Ranging

Autor: Gottfried Magerl, Thomas Faseth, Klaus Witrisal, Stefan Grebien, Holger Arthaber, Florian Galler

Publikováno v: IEEE Journal of Radio Frequency Identification. 1:32-38

This paper presents measurement results of a recently introduced time of flight (ToF) ranging method for backscattering radio frequency identification (RFID) tags. The measurements are done with off-the-shelf EPC Class1 Gen2 tags, an automated tag po

Range Estimation and Performance Limits for UHF-RFID Backscatter Channels

Autor: Erik Leitinger, Stefan Grebien, Klaus Witrisal, Florian Galler, Josef Kulmer, Michael Goller, Holger Arthaber

Publikováno v: IEEE Journal of Radio Frequency Identification. 1:39-50

The accuracy of time-of-flight-based ranging over ultra-high frequency (UHF) radio frequency identification (RFID) backscatter channels is fundamentally limited by the available bandwidth and highly dependent on the channel characteristics. Comprehen

Complex-Valued Delta RCS Simulation of RFID Tags for Time of Flight Ranging Performance Assessment

Autor: Florian Galler, Daniel Neunteufel, Holger Arthaber

Publikováno v: RFID-TA

For the characterization of a backscatter based radio frequency identification (RFID) tag, delta radar cross section (△RCS) measurements are commonly used. While the magnitude of the △RCS is sufficient for describing basic performance parameters,

Experimental Evaluation of a UHF-MIMO RFID System for Positioning in Multipath Channels

Autor: Holger Arthaber, Daniel Neunteufel, Florian Galler, Ulrich Mühlmann, Stefan Johannes Maier, Stefan Grebien, Klaus Witrisal

Publikováno v: RFID-TA

This paper presents an experimental evaluation of an ultra-high-frequency (UHF) multiple-input-multiple-output (MIMO) radio-frequency identification (RFID) system for positioning. To this end, we propose a set of novel parametric maximum likelihood d

Comprehensive Measurement of Complex-valued Delta Radar Cross-section

Autor: Florian Galler, Daniel Neunteufel, Holger Arthaber

Publikováno v: EURFID

While the magnitude of the delta radar cross-section (DRCS) is sufficient to characterize narrowband UHF radio frequency identification systems, new broadband localization approaches require knowledge of the frequency dependent complex-valued DRCS. I

UHF-RFID backscatter channel analysis for accurate wideband ranging

Autor: Klaus Witrisal, Stefan Hinteregger, Holger Arthaber, Josef Kulmer, Florian Galler, Michael Goller

Publikováno v: RFID

Positioning and ranging within UHF RFID are highly dependent on the channel characteristics. The accuracy of time-of-flight based ranging systems is fundamentally limited by the available bandwidth. This paper first analyzes the UHF RFID backscatter
