Self-Calibrated Indoor Tracking from Backscatter Fiducials under NLOS Transmitter Illumination
Hüseyin Yiğitler, Kalle Ruttik, Jingyi Liao +2
This paper studies indoor tracking from wall-mounted backscatter fiducials in corridor segments outside direct transmitter illumination. In the measured setup, the transmitter-to-f…
Backscatter Assisted Indoor NLOS Positioning
Kalle Ruttik, Hüseyin Yiğitler, Jingyi Liao +2
Passive backscatter devices (BDs) can enable indoor non-line-of-sight (NLOS) positioning by serving as virtual anchors whose Doppler-separated signatures are observable in standard…
Dual-Hop Joint Visible Light and Backscatter Communication Relaying under Finite Blocklength
Boxuan Xie, Lauri Mela, Alexis A. Dowhuszko +3
This paper investigates a dual-hop joint visible light communication (VLC) and backscatter communication (BC) relaying framework under the finite blocklength (FBL) constraint, aimi…
Ambient Backscatter Communication in LTE Uplink Sounding Reference Signal
Jingyi Liao, Tianshu Zhang, Kalle Ruttik +2
Ambient Internet of Things (AIoT), recently standardized by the 3rd Generation Partnership Project (3GPP), demands a low-power wide-area communication solution that operates severa…
Thin Film Reconfigurable Intelligent Surface for Harmonic Beam Steering
Boxuan Xie, Aleksandr D. Kuznetsov, Lauri Mela +4
This letter explores an implementation of a novel thin film 1-by-4 reconfigurable intelligent surface (RIS) designed for future communication and sensing scenarios. Utilizing cost-…
Coded Backscattering Communication with LTE Pilots as Ambient Signal
Jingyi Liao, Kalle Ruttik, Riku Jantti +1
The 3GPP has recently conducted a study on the Ambient Internet of Things (AIoT), with a particular emphasis on examining backscatter communications as one of the primary technique…
Zero-energy Devices for 6G: Technical Enablers at a Glance
Onel López, Ritesh Kumar Singh, Dinh-Thuy Phan-Huy +13
Low-cost, resource-constrained, maintenance-free, and energy-harvesting (EH) Internet of Things (IoT) devices, referred to as zero-energy devices (ZEDs), are rapidly attracting att…
Ambient backscatter communications using LTE cell specific reference signals
Kalle Ruttik, Xiyu Wang, Jingyi Liao +2
Long Term Evolution (LTE) systems provide ubiquitous coverage for mobile communications, which makes it a promising candidate to be used as a signal source in the ambient backscatt…
