Resumen

Abstract There has been growing interest in the use of passive harmonic RFIDs for diverse range of applications. Conventional RFIDs are prone to self-jamming and multipath interference, and these challenges can be mitigated using the harmonic RFID design. Recently several harmonic RFID designs have been demonstrated. However, there are many designs related, packaging and intellectual property challenges associated with new tag designs. It has been well known that conventional RFIDs produce harmonic content, which is typically suppressed to reduce background noise. Previous experiments have demonstrated that the harmonics generated by conventional RFIDs can be utilized to enhance their performance. In this paper, an RFID chip is characterized for the generation of harmonic frequencies. This is carried out by designing a high frequency board that contains calibration structures along with structures to characterize the RFID chip using a one port network. An equivalent model is then developed, which in turn is used to design a dual band antenna that works at the fundamental and harmonic frequencies. In addition, the conventional RFID interrogator is modified to accommodate the measurement of harmonics generated by the RFIDs. A complete harmonic tag system is designed and implemented, and an example application of harmonic RFID is demonstrated. Here, the harmonic RFID tag is used in an industrial setting where there is large clutter (large reflections from metal structures).

Resumen

This paper examines attitudes towards Radio Frequency Identification (RFID) technology and explores the wider concerns of the ever increasing prospect of social tagging. Capturing vignettes and narratives from a sample of study participants, the paper highlights concerns about adopting RFID implements now and in the future. The views captured through qualitative methodology act as the platform for a wider argument concerning the human rights and privacy intrusion concerns over IT applications. Intended as an insight into the reality of technology impact, this paper lists a series of questions for leaders to consider over matters of human rights specifically concerning RFID adoption. The authors conclude that caution, naivety and fear are the underlying reasons for society accepting RFIDs without question and that RFIDs will be a part of everyday working and domestic life in the near future.

Resumen

The world’s oil and gas is transported using a network of steel pipelines most of which lie underground. The length of this network in the US/Canada alone is 3.5 million kilometers. Keeping track of pipes in such a network for pipeline-health monitoring, maintenance, and logistics is an acute problem faced by pipeline-operators. Recently, radio-frequency-identification tags (RFIDs) have been proposed for tracking pipelines and even for monitoring pipeline health with additional built-in sensors. Low-cost RFID tags are wirelessly powered and battery-less. However, RFIDs do not function optimally in the presence of magnetic carbon steel pipes that are prevalent in the industry. High-frequency wireless signals also attenuate rapidly through wet soils. In this research, the use of passive RFID sensor platforms for interrogating buried pipes up to 1.25 m deep in the LF bands is proposed. Using magnetic-induction-based communication, a test-comparison between conventional full/half duplex (FDX/HDX) and sequential (SEQ) RFID schemes is detailed. Wireless measurements in the presence of an industry-standard ASTM A-53 carbon-steel pipe show a SEQ RFID offering better immunity against magnetic proximity effects of the pipe’s wall with an 8.3 dB (x6.8) improvement over a FDX/HDX RFID operating under similar conditions over a distance of 80–125 cm at which pipes are typically buried.

Resumen

There will be increasing demand for high confidentiality, integrity, authentication, for widely deployment of the next RFID generation beside that, the focus will be on avoiding encryption algorithms; as these require more complex modulation, to secure communication between RFID’s tags and readers. In this paper, the focus will be on securing the communication channel between tags and readers at the physical layer, rather than to secure the contents of RFIDs data by encryption. The RFID reader initially will communicate with the tag through a narrowband communication and subsequently through broadband communication, by generating ultra wide-band signal using pulse position modulation with time hopped, it can be a novel approach for RFID security as it simplify or eliminate cryptographic requirements with the same security level of existing passive RFIDs, also it allow simultaneous multiple access without-collision, which will enhance the overall RFID systems performance. The design of the system will be shown by modeling the communication, the designing details of the transmitter as well as the receiver, finally showing the simulated results of modulated signal with its specific parameters as well as the receiver performance.

Resumen

The purpose of this study is to describe a methodology to assess the financial viability of radio frequency identification (RFID) applications and the main contributions of this technology. The impact of RFID technology on supply chain processes was assessed using an Internal Rate of Return analysis. An extensive, six-month discussion and refinement process with the logistics and supply chain managers of the company under study was conducted to validate the procedure and to collect the necessary data. Such technology enables inventory control, tracking of parts/products and customer satisfaction. The viability of using RFID technology for inventory control and product tracking was confirmed. Among the benefits obtained: the reduction of one worker from the inventory team, reduction in the costs for replacing a component and reduction in the costs incurred with defective components were found. This is one of the few attempts to quantify RFDI technology’s contribution.Keywords: Economic Engineering. RFID. Radio Frequency Identification. Financial Viability Analysis. Internal Rate Of Return.

Resumen

Abstract: Increased protection of resource-constrained devices, such as radio frequency identification (RFID) systems, is in high demand these days. For high-resource desktop PCs, current encryption techniques are sufficient. Access control systems, transaction banking systems, and payment systems are all examples of high-security applications where RFID technology are used. The attacker tries to deceive RFIDs in order to gain illegal access to services without paying for them or to get around security measures by detecting a secret password. The most difficult problem with RFID systems is ensuring effective protection against such infringements. For RFID systems, lightweight cryptography can give security assurance. SLIM is a novel ultralightweight cryptography technique for RFID devices presented in this paper. Since block ciphers are the most commonly used cryptographic and provide highly strong protection for IoT devices, SLIM is a 32-bit block cipher based on the Feistel structure. The most difficult aspect of creating a lightweight block cipher is balancing performance, cost, and security. SLIM, like all symmetric block ciphers, encrypts and decrypts using the same key. The suggested method performs well in both hardware and software contexts, has a small implementation footprint, a reasonable cost/security ratio for RFID devices, and is energyefficient. SLIM has shown high immunity to the most successful linear and differential cryptanalysis assaults, as well as a substantial margin of defense against them.

Resumen

The ubiquity of illumination facilities enables the versatile development of Visible Light Communication (VLC). VLC-based research achieved high-speed wireless access and decimeter-level indoor localization with complex equipment. However, it is still unclear whether the VLC is applicable for widely-used battery-free Internet-of-Things nodes, e.g., passive RFIDs. This paper proposes LightSign, the first cross-technology system that enables passive RFID tags to receive visible light messages. LightSign is compatible with commercial protocols, transparent to routine RFID communications, and invisible to human eyes. We propose a pseudo-timing instruction to achieve microsecond-level light switching to modulate the VLC message. To make it perceptible to passive RFIDs, we design an augmented RFID tag and prove its effectiveness theoretically and experimentally. With only one reply from an augmented tag, LightSign can decode 100-bit-long VLC messages. We evaluate LightSign in real industry environments and test its performance with two use cases. The results show that LightSign achieves up to 99.2% decoding accuracy in varying scenarios.

Resumen

Residual feed intake (RFI) gained attention as a potential alternative to the feed conversion ratio (FCR). Thus, this study aimed to estimate genetic parameters for different feed efficiency (FE) traits (FCR, RFI1 to RFI5) and their genetic correlation to on-test daily weight gain (ADG), backfat (BFT), loin muscle area (LMA), lean percentage (LP), and total feed intake (FI) for 603 Male Duroc (DD), 295 Landrace (LL), and 341 Yorkshire (YY). The common spatial pen effect was also estimated in these traits. Five RFI measures were estimated by regressing daily feed intake on initial testing age (ITA), initial testing weight (IBW), and ADG for RFI1; other models were the same as RFI1 except for additional BFT for RFI2; LMA for RFI3; BFT and LMA for RFI4; BFT, LMA, and average metabolic body weight (AMBW) instead of IBW for RFI5. Genetic parameters estimated using two animal models and the REML method showed moderate heritability for FCR in all breeds (0.22 and 0.28 for DD, 0.31 and 0.39 for LL, 0.17 and 0.22 for YY), low heritability for the majority of RFI measures in DD (0.15 to 0.23) and YY (0.14 to 0.20) and moderate heritability for all RFI measures in LL (0.31 to 0.34). Pen variance explained 7% to 22% for FE and 0% to 9% for production traits’ phenotypic variance. The genetic correlation revealed that selection against less complex RFI1 in DD and LL and RFI2 in YY would bring the most advantageous reduction to FI (0.71 for DD, 0.49 for LL, 0.43 YY) without affecting ADG in all breeds (0.06 for DD, −0.11 for LL, 0.05 for YY), decrease in BFT, and increase in LP in DD (0.51 in BFT, −0.77 in LP) and LL (0.45 in BFT, −0.83 in LP). Therefore, inclusion of these breed-specific RFI measures in the future selection criteria would help improve feed efficiency in the swine industry.

Resumen

SCA transports timber via rail from railway terminals in western Sweden to saw and/or pulp mills located on the east coast. Sometimes timber wagons are lost due to damages inflicted when loading the wagon. Wagons can also be decommissioned for maintenance conducted by the Swedish Transport Administration. Both situations are unpredictable and causes many types of problems. If the wagons could be automatically traced these problems could be predicted and pre-emptive actions could be taken. All wagons used by SCA are equipped with RFID tags and RFID readers are installed at the railway terminals. The purpose of this thesis is to equip the RFID readers with Internet access, collect the data read by the RFID readers and present this data in a single page web application. The actual data collection is done by an already existing system which pushes the train data to the back-end part of the application. The front-end part is made with a JavaScript framework named Ember.js and the back-end part is made with ASP .NET Web API and SQL Server. The application is finished and verified with various tests but is not put in production due to a negotiation delay between SCA with a third-party consultant.

Resumen

L'identification par radio fréquence (RFID) est une technologie utilisant les ondes radio pour détecter, localiser et identifier des objets sur lesquels on place des étiquettes électroniques ou tags. Cette technologie, avec des fonctionnalités de détection supérieures à 2m, est destinée à remplacer le code-barre existant depuis les années 1970. Durant la dernière décennie, le développement de la RFID UHF a permis d'élargir le domaine des applications qui compte entre autres le marquage d'objets, le contrôle d'accès, la traçabilité, la logistique, l'inventaire, et même les transactions financières. Avec cette augmentation de la demande de services d'identification, les prévisions pour le marché de la RFID (actuellement dans les 12MM d'euros) montrent une augmentation de 3MM d'euros par an dans les 10 prochaines années. Actuellement la RFID UHF présente plusieurs limitations technologiques fortes expliquant que son développement est moins rapide que ce qui avait été envisagé il y a une vingtaine d'années. Deux problématiques industrielles importantes sont abordées dans ce travail. Tout d'abord la variété des supports sur lesquels les étiquettes RFID sont placées, cette variabilité des supports entraînant un déréglage des antennes des tags à cause du changement de la permittivité électrique et/ou de la conductivité du milieu. Dans ce contexte des solutions sont proposées au niveau de tags UHF pour une application sur surfaces en plastique ou en métal. La deuxième problématique est liée au couplage entre antennes lorsque la densité de tags est forte ou aux perturbations de diagramme (masquage) dues à l'environnement proche des antennes. Afin d'améliorer le taux de lecture dans ces conditions, une antenne lecteur miniaturisée à quatre IFAs intégrant de la diversité d'espace, de polarisation et de diagramme a été développée et testée dans un scénario à forte densité de tags
Radio Frequency Identification (RFID) is a technology designed to use the electromagnetic waves backscattering to establish detection and identification for different types of articles. Due to its longer coverage range, this technology seeks to replace the bars code existing since 1970. Recently RFID developments allow the growth in the number of applications including access control, tracking and logistic, inventory, and even electronic contactless payment between others. With this growing in the RFID services demand, the market value previsions (currently in 12MM euros) show an increase of 3MM euros per year during the next 10 years. Nowadays the RFID has many technical limitations that could explain the fact of the slow growth different of the initial estimation twenty years ago. Two main issues in RFID field are treated in this work. Initially, the variety of supports where the tags are placed on, fact that produce an antenna mismatch due to the electrical permittivity variation. For this problem some UHF tags solutions are developed and proposed to enhance the antennas performance for plastic and metallic supports applications. The second issue which is the low detection rate is clearly linked to the antennas coupling when the tags density is high or to the perturbations in the reader's radiation pattern due to the environment next to the antenna. In order to improve the detection-identification rate in these conditions, a four IFA miniaturized reader antenna with diversity is developed and tested

Resumen

RFID-tekniken har under de senaste åren uppmärksammats allt flitigare av företag som tror sig ha användning för det i sin verksamhet. En kategori av företag som skulle kunna ha stor nytta av tekniken är tillverkande industri, bland annat i sin materialhantering. En undersökning visar att många sådana företag vet att tekniken finns men att graden av kunskap om teknikens möjligheter och brister är starkt varierande.

Detta arbete har studerat vilka brister och problem som uppmärksammats av de företag inom denna kategori som redan idag använder tekniken. Arbetet har bestått av intervjuer av ett antal sådana företag och även av leverantörer av RFID-utrustning.

De företag som ingår i undersökningen inte upplevt några av de problem som arbetet behandlar men leverantörernas erfarenheter visar att problem finns och att det kräver stor yrkeskunskap och erfarenhet för att komma runt dem.

Resumen

Mestrado em Engenharia Eletrónica e Telecomunicações
O interesse por sistemas de identificação por radiofrequência (RFID) tem aumentado de forma significativa nos últimos anos, principalmente na identificação e tracking de objectos, animais e pessoas através de um modo de comunicação sem fios. Esta comunicação é feita por ondas de rádio que são transmitidas por um leitor, através de uma antena a um identificador (etiqueta) que atribui a um objeto uma identidade única, o chamado código de identificação único. Esta tecnologia não só identifica, mas também armazena dados atribuídos a determinado objeto, animal ou pessoa. No entanto, o RFID apresenta ainda consideráveis limitações, que inviabilizam o seu uso. Duas importantes razões que tornam esta tecnologia menos interessante _e o seu excessivo custo, causado não só pelos preços dos leitores e das antenas, mas também pelo preço do processo de fabrico das etiquetas; e devido ao facto de serem usados leitores não-reconfiguráveis a novos protocolos de comunicação, novas etiquetas ou até mesmo alterações de frequências. O primeiro objetivo deste projeto foi então desenvolver um front end de radiofrequência para a construção de um leitor RFID UHF reconfigurável de baixo custo, baseado em circuitos programáveis DSP ou FPGA, com um processador embutido e software-defined radio. Com isto pretende-se que os leitores RFID não dependam de transceivers RFID comerciais. Além disso, com este estudo pretendeu-se também a desenvolver antenas e etiquetas RFID, em material orgânico flexível, com um processo de produção de etiquetas simples e de baixo custo. Na primeira parte deste projeto, foi proposto um front end para a banda RFID UHF Europeia e para a banda Americana, que poderá ser usado, no futuro, no desenvolvimento de um leitor RFID. Este front end foi desenhado para ser robusto, de baixo custo, e com o objetivo de emitir e receber sinais de rádio. Na segunda parte, foram desenvolvidas duas antenas para leitores, uma para a banda RFID UHF Americana e outra para a banda RFID UHF Europeia. Por _ultimo, foi alterada uma impressora convencional, comercialmente disponível, e foram feitas também alterações na tinta de impressão, tornando-a condutora, para impressão de antenas para etiquetas RFID em substratos _a base de papel. Todos os parâmetros fundamentais das antenas foram simulados numericamente e testados experimentalmente. As duas antenas testadas mostraram boas performances, em particular, a antena para a banda RFID UHF Europeia, cujos valores resultantes dos testes experimentais foram muitos similares aos encontrados computacionalmente, sendo mesmo melhores para alguns parâmetros. Esta antena, não só apresentou uma boa performance na banda mencionada, mas também na banda RFID UHF Americana. Foram desenvolvidas sete etiquetas RFID, ou seja, desenhadas e impressas usando a impressora jato de tinta modificada, e testadas posteriormente. Todas as etiquetas funcionaram, embora uma delas não tenha apresentado resultados tão satisfatórios. Podemos então concluir que a nossa tecnologia permitiu ter etiquetas impressas por uma impressora convencional e, desta forma, poderá oferecer uma maior independência ás empresas que as produzem, podendo mesmo ser utilizada em ambientes de I&D, em Universidades ou Escolas, de modo simples e barato.
In recent years, Radio Frequency IDentification (RFID) technology has received special attention, especially for identifying and tracking objects, animals and people through a wireless communication connection. Radio waves transmitted from a reader, through an antenna to an identifier, called tag, which attributes an Unique Identification Number (UID) to a object, animal or person are used for this communication. This technology not only helps to identify, but also to collect data attributes about a certain person or object. However, RFID still has important limitations, which slows down its growth considerably. The two main reasons for that are related not only with the excessive cost of this system due to the readers and antennas, but also because it uses non-reconfigurable readers to new communication protocols, tags or even changes in frequencies. Therefore, the first purpose of this project was to develop a front-end to be included into a low-cost reconfigurable RFID UHF reader, based on FPGA or DSP, with an embedded processor and a software-defined radio. In a long-term, it is intended to have readers that does not require commercial RFID transceivers. The second purpose of this study was to develop a simple and low-cost manufacturing process of antennas and tags in exible and organic material. Firstly, a front end for RFID UHF bandwidth across the European Union and in the North America was proposed to be implemented in the future. This front end was designed to be low-cost, robust, in order to emit and receive radio signals. Secondly, two antennas, respectively, for an American and European UHF bandwidth RFID reader were developed in this project. Ultimately, an ordinary home inkjet-printer was modified to jet conductive ink, created as a part of this study, to print tag antennas in paper based substrate. All of the fundamental parameters that needed to be evaluated for antennas were experimentally simulated and tested for the two antennas. Both showed high performances, particularly, the antenna for a European UHF bandwidth RFID reader. This antenna obtained results more similar to the numerical model, and experimental findings were even better for some parameters. Its performance was found to be high even for an American UHF bandwidth RFID reader. Furthermore, seven RFID tags were developed, meaning they were designed and printed on the modified home inkjet-printer, and then its performance was tested. Although one of these tags showed not to be highly efficient, all tags worked adequately for the purpose. Therefore, we can conclude that our technology allowed to print RFID tags using a modified home inkjet-printer, indicating that this method can offer more independency to RFID tag manufacturers and, also allow an extensive use of this system in I&D environment, University or Schools, since it is simple and cheap.

Resumen

The use of Radio Frequency Identification (RFID) has grown substantially in the past few years. Driven mostly by the retail supply chain management industry and by inventory control (loss prevention), RFID technology is finding more acceptance in the security and personal tracking sectors beyond simple pass cards. This growth has of course resulted in greater acceptance of RFID technology and more standardization of process and systems as well as decreased per unit costs. The oil and gas industry is being exposed to the potential use of RFID technology, mostly through the safety and equipment inspection portion of construction management. However, the application of RFID technology is expected to expand to the material tracking and asset management realms in the near future. Integrating the information provided by RFIDs with EPCM project and owner/operator Geographic Information Systems (GIS) is a logical next step towards maximizing the value of RFID technology. By linking assets tracked in the field during movement, lay-down and construction to a GIS, projects will have accurate, real-time data on the location of materials as well as be able to query about those assets after commissioning. This same capability is being modified for post-commission use of RFID with facility GISs. This paper outlines how existing GISs used during the EPCM phases and those employed after commissioning can display, utilize and analyze information provided by RFID technology.

Resumen

China is one of the world’s largest manufacturers and consumers of Radio Frequency Identification (RFID) applications. Current estimates show that China will need over 3 billion RFID tags to satisfy demand in the year 2009. The applications for RFID patents have spread across a very diverse range of inventions and in the future it is likely that most products manufactured in China will contain an RFID tag. China’s RFID industry has grown along with the demand and researchers are making significant technological advances. In this research, patent data from the State Intellectual Property Office of the People’s Republic of China (SIPO) have been used to explore RFID technology development and its trends. Patent abstracts containing the key word and phrase ‘RFID’ and ‘Radio Frequency Identification’ were collected for analysis, content extraction, and clustering. In total, 1,389 patents from the SIPO database covering the years 1995 to 2008 were retrieved and archived for analysis. Patents provide exclusive rights and legal protection for inventors, play an important role in the development and fair diffusion of technology, and contain detailed specifications necessary to define and protect the boundaries of an invention. Through patent analysis, companies monitor the development of technology and evaluate the position of potential competitors in the market. This research applies patent content analysis to map and interpret the current trends of RFID technology development in China. A patent content clustering method is used to cluster different patent documents into homogenous groups, and then technology forecasting is applied to evaluate possible market opportunities for future inventors and investors. The results suggest that the cluster called RFID wireless communication devices has entered the saturation stage and thus provides limited opportunity for development. Four other clusters; RFID concepts and applications, RFID architecture, RFID tracking implementation, and RFID transmission apparatus, have entered the mature stage. The RFID frequency and waves cluster appears to be in early growth stage with good development potential. Since the technology related to basic RFID concepts and devices has reached a mature stage in China, the research and development seems to be targeting the improvement of the RFID frequencies and waves as a means to develop more reliable RFID systems and applications.

Resumen

RFID tags have been used by railways for many years, RFID has proven its worth in inventory management, yet this technology is underutilized for enhancing railway operations and health monitoring due to limitations of passive RFID technology. Active RFID provides enhanced capabilities with potential to improve railway operations. Active technology differs from passive RFID by incorporating an onboard power source enabling longer ranges, changeable data fields, and the ability to transmit independently of the reader. This paper compares the advantages and disadvantages of active compared to passive RFID in terms of power requirements, transmission range, and dynamic data. A survey of existing products and vendors is presented. The existing active RFID standards are reviewed and elements of the data tag protocols are detailed as well as protocols for mitigating collisions of data packets. Finally, specific railway applications utilizing active RFID are discussed.

Resumen

This paper presents a comprehensive review of ultra-high frequency (UHF) radio frequency identification (RFID) tag antennas. Due to multiple benefits, RFID technology has supplanted conventional methods of identification like barcodes, magnetic stripe cards, and smart cards. The size of the antenna plays a crucial role in determining the overall dimensions of the RFID tag, making antennas typically low profile and compact. It is acknowledged as an innovative approach for tracking because of its affordable price, passive wireless power transfer capabilities, versatility, and non-line-of-sight communication. UHF RFID tag antennas find widespread use in various applications such as supply chain management, asset tracking, and vehicle identification. The UHF antennas are favoured because they enable simultaneous detection of more tags, provide greater read ranges and faster reading rates, and necessitate fewer antennas than low frequency and high frequency antennas. Establishing the application requirements, choosing the ideal antenna design and substrate material, developing, and optimizing the antenna, manufacturing the antenna, and connecting the antenna to the RFID tag are all essential processes in implementing an UHF RFID tag antenna. This paper will cover the overview UHF RFID tag antenna, few applications, and its limitations.
