The proliferation of drones, or unmanned aerial vehicles (UAVs), has raised significant safety concerns due to their potential misuse in activities such as espionage, smuggling, and infrastructure disruption. This paper addresses the critical need for effective drone detection and classification systems that operate independently of UAV cooperation. We evaluate various convolutional neural networks (CNNs) for their ability to detect and classify drones using spectrogram data derived from consecutive Fourier transforms of signal components. The focus is on model robustness in low signal-to-noise ratio (SNR) environments, which is critical for real-world applications. A comprehensive dataset is provided to support future model development. In addition, we demonstrate a low-cost drone detection system using a standard computer, software-defined radio (SDR) and antenna, validated through real-world field testing. On our development dataset, all models consistently achieved an average balanced classification accuracy of $ge 85%$ at SNR $gt -12$ dB. In the field test, these models achieved an average balance accuracy of >80%, depending on transmitter distance and antenna direction. Our contributions include: a publicly available dataset for model development, a comparative analysis of CNN for drone detection under low SNR conditions, and the deployment and field evaluation of a practical, low-cost detection system.

As Radio Frequency Identification (RFID) methods continue to evolve to higher levels of complexity, one form of machine learning is making its appearance. The use of Neural Networks (NN) in the RFID field is steadily increasing, and in the fields of localization and activity recognition, promising results are being shown from a variety of research. RFID applications fall primarily under two types of problems including regression and classification. We analyze RIFD localization techniques which fall under regression, and activity recognition which falls under classification. Many works don’t classify themselves as activity recognition methods, but because they fall under the classification category, we still consider them as activity recognition techniques. This research overviews the Neural Network models in the localization field based on whether they can perform independently of the environment in which they were tested. For activity recognition and accessory fields, the major methods involve tag-based and tag-free approaches. After the models are surveyed, a comparison study is given to examine what may be the cause for increased accuracy between different Neural Network models.
随着射频识别（RFID）方法不断向更高的复杂度发展，一种机器学习的形式正在出现。神经网络（NN）在 RFID 领域的应用正在稳步增加，在定位和活动识别领域，各种研究都取得了可喜的成果。RFID 应用主要分为两类问题，包括回归和分类。我们分析的 RIFD 定位技术属于回归问题，而活动识别属于分类问题。许多作品并没有将自己归类为活动识别方法，但由于它们属于分类范畴，我们仍将其视为活动识别技术。本研究概述了定位领域的神经网络模型，其依据是这些模型是否能独立于测试环境。在活动识别和附件领域，主要方法包括基于标签和无标签方法。在对模型进行调查后，还进行了比较研究，以探讨不同神经网络模型之间提高准确性的原因。

This paper describes a negative resistance reflection amplifier for BPSK modulation RFID tag. The amplifier has a cascode configuration with a source degeneration capacitor and resistor. The capacitor with 1-bit binary capacitance controlled by a FET switch can realize two different impedances with negative resistance in which those impedance phase difference is close to 180 degrees. The fabricated amplifier using HEMT devices achieves 25 dB gain with the phase difference of $180~pm ~10$ degrees between reflection coefficient point $boldsymbol {varGamma }_{0}$ and $varGamma _{1}$ for BPSK modulation with a power consumption of $160~mu $ W. Friis transmission equation suggests that the tag incorporating our amplifier could extend the up-link communication range up to 40m.

The rise and progression of the Internet of Things (IoT) have reshaped how devices connect and share information, leading to more intelligent and interconnected settings. In this realm, the incorporation of self-sustaining millimeter-wave Identification (mmID) devices present a compelling opportunity to elevate IoT implementations, especially concerning accurate positioning and monitoring capabilities. In this work, the authors introduce a novel lens-enabled passive mmID tailored for highly accurate localization and precise 2-axis orientation detection. Equipped with a frequency diverse pixel antenna array and integrated with a low-loss 3D lens for improved performance, the mmID demonstrates a peak monostatic RCS of −29.2 dBsm with a −10 dB angular coverage of ±55° across all cuts, translating to a solid angle coverage of 2.679 sr about boresight. A theoretical link budget analysis is provided for the lens-based mmID, projecting a maximum reading range of 868 m when utilizing the maximum allotted 75 dBm EIRP for 5G/mmWave frequencies. Employing a proof-of-concept (PoC) reader with 30 dBm EIRP, the proposed system demonstrates highly accurate localization, with a mean error of <2 cm at distances up to 45 m, and utilizes sensitive phase information to achieve an average phase-based ranging error within 1 mm across distances up to 20 m. Additionally, a novel signal processing methodology employing multi-output Classification Convolutional Neural Networks (CNN) is introduced to accurately discern the 2-axis orientation of the mmID, resulting in a mean error of <5° at ranges up to 30 m. By offering superior precision and versatility, the passive mmID solution emerges as a promising advancement for next-generation 5G/mmWave Cyber-Physical Systems (CPS) and IoT applications.

This research introduces a novel circularly polarized compact antenna designed for universal ultrahigh-frequency (UHF) radio-frequency identification (RFID) handheld readers for Bi-directional RFID Far-field Applications. The antenna features a microstrip feed positioned at the center opposite a slot-based square ground. The ground plane is perturbed to include a thin horizontal and vertical stub on the left side, along with a thick rectangular slot at the right side of the square ground plane to achieve circular polarization. The simulated antenna provides a 3-dB axial ratio bandwidth (ARBW) of 42 MHz (831–873 MHz), a 10 dB impedance bandwidth of 15% (814–945 MHz), and a peak gain of 5.0 dBi. The antenna is fabricated on both layers of an affordable FR4 substrate, measuring $81times 81times 1.6~{mathrm { mm}}^{3}$ and its measurement results are in close agreement with simulated. The application of this antenna is made with a commercial UHF RFID reader module. The obtained read range and field of view confirm that this proposed antenna is a promising option for compact universal UHF RFID handheld reader applications and other Internet of Things (IoT) based applications.

The advent of 6G wireless systems promises a digital world that blends physical and virtual elements, revolutionizing our interaction with the physical environment. A critical step towards this digital world is the creation of digital twins of physical systems and objects. The Internet of Things (IoT) plays an important role in connecting and monitoring these physical entities. However, connecting all objects in our daily life is challenging due to high density and large number of devices. Near Field Communication (NFC), utilizing High Frequency (HF) band signals, emerges as a promising solution. NFC has a short communication range and high penetration efficiency, with a reliable wireless channel that does not compete for spectrum with typical cellular and local area networks. Nevertheless, its extremely short range limits its use in autonomous IoT applications. This paper explores two techniques to extend NFC’s communication range and reliability: the use of high-quality factor transmit/receive coils and high-quality factor relay coils. Additionally, the effect of tag coil coupling in a multi-tag IoT environment is examined. Analytical models are developed to evaluate these approaches, and the results are validated using COMSOL Multiphysics. The findings demonstrate a significant increase in NFC’s communication range, i.e., up to 0.9 – 1.3 m for 1 – 10 W transmit power, making it suitable for ultra-dense battery-free IoT operations.

This paper presents a novel Digital Traffic Engineers (DTEs) framework, leveraging Large Language Models (LLMs) to intelligently interpret human language and automate the creation of traffic control strategies. This advancement eliminates the need for manual scheme creation, reducing the workload of human traffic engineers (HTEs) and significantly improving the efficiency from requirement to control scheme generation. Experimental results in scenario understanding and traffic control underscore the potential of DTEs to effectively perform tasks traditionally managed by HTEs. This synergy between HTEs and DTEs not only streamlines traffic management processes but also paves the way for more adaptive, responsive, and environmentally friendly urban transportation solutions.

Passive radio-frequency identification (RFID) technology has recently been applied to many battery-free wireless medical and healthcare (WMH) applications including wearable and implantable medical devices. The presence of the human body near RFID devices creates, however, several challenges in terms of design, fabrication, and testing of such WMH devices. The use of comparatively unsecured wireless links enabled by RFID communication may also jeopardize patient’s privacy as well as raise ethical concerns. With these factors in mind, this article provides a systematic review spanning two decades of the wide range of passive RFID applications in medical and healthcare devices based on the classification of RFID frequency bands. The strengths and limitations of these techniques are benchmarked against each other using performance metrics such as communication distance, tissue safety, size of the devices, as well as patient’s privacy and ethical implications. The article concludes by discussing the future opportunities and challenges raised by passive RFID for battery-free WMH devices. This comprehensive literature review aims to become a point of reference for experts and non-experts in the field.
无源射频识别（RFID）技术最近已被应用于许多无电池无线医疗和保健（WMH）应用中，包括可穿戴和植入式医疗设备。然而，由于 RFID 设备附近存在人体，因此在此类 WMH 设备的设计、制造和测试方面带来了一些挑战。使用相对不安全的无线链路进行 RFID 通信还可能危及病人的隐私，并引发道德问题。考虑到这些因素，本文根据 RFID 频段的分类，对二十年来医疗和保健设备中广泛的无源 RFID 应用进行了系统回顾。文章采用通信距离、组织安全性、设备尺寸以及病人隐私和伦理影响等性能指标，对这些技术的优势和局限性进行了比较。文章最后讨论了无源射频识别技术为无电池 WMH 设备带来的未来机遇和挑战。这篇全面的文献综述旨在为该领域的专家和非专家提供参考。
