Backscatter radio is a promising technology for low-cost and low-power Internet-of-Things (IoT) networks. The conventional monostatic backscatter radio is constrained by its limited communication range, which restricts its utility in wide-area applications. An alternative bi-static backscatter radio architecture, characterized by a dis-aggregated illuminator and receiver, can provide enhanced coverage and, thus, can support wide-area applications. In this paper, we analyze the scalability of the bi-static backscatter radio for large-scale wide-area IoT networks consisting of a large number of unsynchronized, receiver-less tags. We introduce the Tag Drop Rate (TDR) as a measure of reliability and develop a theoretical framework to estimate TDR in terms of the network parameters. We show that under certain approximations, a small-scale prototype can emulate a large-scale network. We then use the measurements from experimental prototypes of bi-static backscatter networks (BNs) to refine the theoretical model. Finally, based on the insights derived from the theoretical model and the experimental measurements, we describe a systematic methodology for tuning the network parameters and identifying the physical layer design requirements for the reliable operation of large-scale bi-static BNs. Our analysis shows that even with a modest physical layer requirement of bit error rate (BER) 0.2, 1000 receiver-less tags can be supported with 99.9% reliability. This demonstrates the feasibility of bi-static BNs for large-scale wide-area IoT applications.

This letter aims to significantly improve the communication performance of Radio Frequency Identification (RFID) tags that transmit to Bluetooth devices. Such tags are increasingly being researched in order to provide the benefits of RFID without the need for expensive stand-alone readers. Strictly speaking, these tags do not generate Bluetooth standards-specified waveforms, but are nevertheless compatible with standards-compliant receivers. Gaussian Frequency Shift Keying (GFSK) transmission is replaced by simpler FSK transmission from the tag. This letter analyzes the mismatch effects when FSK signals are demodulated by GFSK receivers. This letter also describes a new tag signaling technique that generates waveforms better matched to Bluetooth receivers than FSK waveforms. The novel technique can be implemented with tag hardware that can generate classical FSK waveforms. Bit error rate improvement of about 5 dB were observed in simulations. Tag coverage area is nearly doubled.

Fingerprinting stands as an effective non-intrusive and non-destructive method to ensure physical security in wireless systems and Radio-Frequency Identification (RFID) applications. Conventionally, the most common state of the art approach involves extracting signal features from the devices and employing machine learning techniques for the classification of counterfeit or cloned ones. This paper explores how to enhance RFID antenna electromagnetic fingerprints by proposing a multi-power interrogation approach. Unlike traditional methods, our technique emphasizes the non-linear behavior of RFID integrated circuits (ICs) by properly varying the reader input power and frequencies. This strategy increases the unpredictability of the IC impedance modulation, thereby extracting richer and more complex information from the RFID tags. Using Shannon Information Theory, we can quantify the entropy of these enhanced fingerprints, revealing an average increase of almost 2 bits in the information content compared to single-power level interrogations. Our findings can lay the foundations to implement more robust RF physical unclonable functions (PUFs) with robust physical keys against counterfeiting and replication threats.

A simple, single-layer anti-metal tag that is designed using a truncated patch antenna has been proposed. The patch configuration is simple as it only requires the use of two truncated corners and an inclined I-slit as its effective tuning mechanisms, all of which can be easily made on the single surface of a substrate. With the application of the two tuning mechanisms, the tag resonant frequency can be easily tuned by adjusting the geometrical parameters of the truncations and the I-slit, without the involvement of metallic vias/stubs and multiple-layer structures. It makes such a tag convenient for mass manufacturing. The proposed tag has a miniature size (40 mm $times $
