Radio tomographic imaging (RTI) is one of potential device-free localization (DFL) technologies. Solving RTI model is an ill-posed problem that the number of measurements is less than pixels in a reconstruction image. Currently, the Tikhonov regularization based least square method (TRLS) is used to handle the problem, but its artificial regularization parameter disturbs initial RTI model and results in low localization accuracy. Gradient iteration regularization method (GIRM) is proposed to solve RTI model and has the advantages of high accuracy, low storage cost, good convergence and high stability. Unlike the TRLS, it uses mathematical deviation to obtain its parameter required for the solution and adopts several iterations to further weaken the influence of the parameter on the model. The image processing eliminates false targets and artifacts in a reconstruction image to obtain the number and the locations of real targets. Simulation shows that the localization performance of proposed method is higher than TRLS.

This paper describes a smart system based on the Radio Frequency Identification Technology (RFID) and conceived within the SENERGY Project for worker safety applications. An RFID tracking system allows to monitor the worker position during the maintenance activities on machinery assemblies, thanks to a synthetic-array approach. The reader antenna moves above the machinery assembly area through a 3D-axis cartesian portal. The worker equipped with several passive UHF-RFID tags is tracked in real-time with errors comparable with body sizes, thus improving the safety and health requirements of the system.

Ambient backscatter communication (AmBC) systems utilize existing ambient radio frequency (RF) signals to establish an indirect communication link between a transmitter (TX) and a receiver (RX). Backscatter devices (BDs) modulate their useful information on the incoming ambient signal emitted by the TX, as such their range is usually a very short event when only one BD is considered. This paper aims to analyze the impact of the interference generated due to the presence of another BD in a bi-static backscatter communication system. It is observed from the simulation results that the received signal degradation is mostly due to the cross interference of the other BD, which can be mitigated using successive interference cancellation (SIC) techniques. The level of both cross interference and self interference is significant when the interfering BD is located close to the target BD or the receiver. Therefore, AmBC systems can support more than one BD in an environment as long as the BDs are placed more than a wavelength apart from each other and RX.

Interferences, like reader-to-tag interferences, and shadowing can lower the performance of ultra high frequency (UHF) radio frequency identification (RFID) vehicle identification systems on highways. Thus, it is important to know how much influence these effects have on the reliability of such systems, which is the main goal of this work. To get an appropriate model for the reader-to-tag interferences, measurements of the number of reads per minute in a two-reader environment are shown. It turns out that at a signal to interference ratio (SIR) of more than 6 dB the desired reader dominates the communication over the interfering reader. With this model, the impact of the reader-to-tag interferences is analyzed by simulating two scenarios; a car driving along the center of a lane and driving between two lanes. It turns out that the number of reads is reduced by $approx$ 63.2% if the car drives between two lanes but that the absolute number of 25 is still enough to allow a robust identification. A third scenario, where a truck is driving in front of a car, shows that shadowing is negligible regarding the number of reads, even for relatively small distances between the vehicles.

This paper presents a dual-band circularly-polarized cross-dipole antenna for RFID readers. The proposed configuration is comprised of two crossed dipole pairs, with each pair consisting of orthogonal elements designed on front and back sides of the substrate. Double quarter wavelength delay lines are used to connect the dipole elements and introduce a 90° phase difference, resulting in circular polarization in both bands. The impedance bandwidth of the antenna is 13.16 % in the 900 MHz band and 13.6 % in the 2450 MHz band. The axial ratio bandwidth of the antenna is 3.08 % in the 900 MHz band and 1.63 % in the 2450 MHz band. Coaxial cable is used to feed the structure, which eliminates the need for complicated feeding networks. The antenna configuration has an overall size of $(65 times 65 times 1.6)$ mm3.

This paper presents the impact of the non-linear behavior of UHF RFID chips on the backscatter radiated signals by commercial RFID tags. In particular we analyze and quantify the power level of the third harmonic backscattered signals by the tags. The study shows the presence of a third harmonic signal for all tested UHF RFID tags, including tags equipped with the most recent chips. The measurement shows that the level of the radiated third harmonic signals is strong enough to be detected and potentially processed. In addition, if the radiated power of the third harmonic signal varies from one tag to another having the same chip and different antennas, this variation is minor considering identical tags.

Forced ripening through the exposure of fruits to controlled environmental and gases conditions is nowadays one of the most assessed food technologies especially for climacteric and exotic products. However, a fine granularity control of the ripening process and consequently of the goods quality is still missing, so that the management of the ripening room is mainly based on qualitative estimations only. Following the modern paradigms of Industry 4.0, this contribution proposes a nondestructive RFID-based system for the automatic evaluation of the live ripening of up to 128 avocados inside the ripening room. The system, coupled with a properly trained automatic classification algorithm, is capable to discriminate the early stage of ripening with an accuracy greater than 85%.

In this paper, we introduce the new concept of Crowd-Detectable Zero-Energy-Devices. Such devices harvest solar or ambient light energy to power themselves, backscatter ambient waves to communicate, and are detected simultaneously by a smartphone connected to the network, and the network itself, as long as the device is close to the considered smartphone. Such device is a promising sustainable solution for the future of the Internet of Things. We describe an example of use case: asset tracking with zero added energy, zero new signals and zero new infrastructure in the network, thanks to the anonymous and transparent participation of smartphones connected to the wireless network. We then present our first prototypes of such devices that backscatter TV, 4G and 5G signals, and show our first experiments in challenging conditions and environments.

In this paper, we propose a safety alert system based on LoRa(Long Range) communication, where the communication takes place in the range of kilometers. Because of the long-range, the low power consumption, and the long battery, our proposed system can continuously operate without disruption. In India, It is recorded that average of 87 rape cases daily in 2019 and overall 4,05,861 cases of crime against women during the year, a rise of over 7% from 2018, the latest government data released on September 29, 2020[1]. These statistics show how weak we are in terms of the safety of women in India. So to reduce crime against women, our proposed prototype will give the long-range alert signal along with the GPS location with a single push of a button.
