Abstract:

Since the inception of the backscatter-radio technology, this field has continually evolved. As a result, this technology is used for a multitude of applications like personnel identification, logistics and assets management and military purposes etc. Radio Frequency Identification (RFID) technology works in several ISM-frequency bands. This work pertains to the design and development of an RF tag that uses 5.8 GHz ISM band for backscatter. This frequency band has many inherent advantages like higher gain antennas, smaller sized tags, increased immunity to conductive object losses, and larger RF bandwidth. The objective of this research is design and prototype development of an RF tag capable of sensing acceleration, angular motion, and shock experienced by an object on which it is installed. The sensed information is modulated onto an incident continuous wave (CW) and backscattered to the reader. Literature research suggested that such work has not been done previously using an RFID platform. The challenges include integration of the sensor, antenna and other electronics to efficiently backscatter the information to the receiver, designing a suitable planar antenna, realtime backscattering of the sensed information, and low power consumption. As a further step, it is required to design and integrate two antennas on RF tag to simultaneously backscatter the same information; and to measure and compare its effect with single antenna tag. The sensed impact/shock and rotational movement information from the inertial sensors (accelerometer and gyroscope) was backscattered instantly and displayed on the custom developed graphical user interface. The development of GUI was not part of this project and was developed by another lab member. RF Tags with single and dual antenna configurations were designed and tested. It was observed that by increasing the number of antennas higher read range can be achieved. Moreover, by doubling the antennas the radar cross-section for the tag was approximately doubled.

Abstract:

This thesis presents an experimental study both in the laboratory and field to develop and test a method for continuously measuring and monitoring scour using an automated identification technology known as Radio Frequency Identification (RFID). RFID systems consist of three main components, namely (a) the reader which controls the system, (b) the transponder (derived from transmitter/responder) that transmits data to the reader and (c) the excitation antenna that allows the communication between the reader and the transponder. The study provides an insight into the RFID technology and develops the framework for using this technology to eventually address two central themes in river mechanics and sediment transport; (a) the determination of the active layer thickness and (b) the scour/deposition depth around a hydraulic structure. In particular, this study develops the methodology for relating the signal strength of a radio frequency (RF) device with the distance between an excitation antenna and the RF device. The experiments presented herein are classified into two main groups, (1) the laboratory and (2) the RF signal vs. the detection distance experiments (field experiments). The laboratory experiments were designed to understand the effect of key RFID parameters (e.g., transponder orientation with respect to the excitation antenna plane, maximum antenna-transponder detection distance), measured in terms of the transponder return RF signal strength for various antenna-transponder distances, transponder orientations with respect to the excitation antenna plane and different mediums in between the excitation antenna and the transponder, on the overall performance of the RFID system. On the other hand, the RF signal vs. the detection distance experiments were based on the results obtained during the laboratory experiments and focused on developing calibration curves by relating the transponder return RF signal strength with the distance between the excitation antenna and a transponder. The laboratory results show that the dominant RFID parameters affecting the system performance are (a) the transponder orientation towards the excitation antenna plane and (b) the medium type in between the excitation antenna and the transponder. The differences in reading distances were attributed to the transponder inner antenna type, while the effect of the medium was related with the void ratio, where higher porosity materials have, less RF signal strength decay. The parameter that governs the RF signal strength decay was found to be the distance between the excitation antenna and the transponder (erosion process experiments). The RF signal strength decays almost linearly with distance, while the rate of the RF signal strength decay is controlled by the material type in between the excitation antenna and the transponder (deposition process experiments). The RF signal vs. the detection distance experiments demonstrate that the reading distance of the RFID system can be significantly increased by using a custom made excitation antenna. The custom made excitation antenna not only increases the reading distance between the antenna and the transponder to nearly 20 ft., but also allows the user to manipulate the excitation antenna's shape and size to meet the specific landscape requirements at the monitoring site.

Radio frequency identification (RFID) has an enormous potential impact within the semiconductor supply chain, especially within semiconductor manufacturing. The end benefit of RFID will be in the mass serialization, and the subsequent tracking and tracing, of individual semiconductors, or what is referred to as Unit Level Traceability (ULT). Before all of the technical hurdles of ULT are overcome, however, there exists a host of other applications for RFID within semiconductor manufacturing. The identification of what can and what should be RFID-tagged and read, the analysis of how to collect this information and what to do with the data, and the implementation of some targeted opportunities will provides valuable information with regards to the technical and logistical hurdles of RFID within semiconductor manufacturing far before ULT becomes a reality.

Abstract:

In recent years, passive radio frequency (RF) tags that communicate using modulated backscatter radiation have shown great potential for use in inventory management, parcel and postal tracking, for use as remote sensors, and in a host of other Radio Frequency Identification (RFID) applications. However, for the widespread use of these tags to become reality, much basic research is needed to reduce the cost, increase the range, and increase the reliability of the RF tag. This research seeks to enhance the performance of passive RF tags by developing a series of tests, or radio assay, to measure the following: the performance of RF tag antennas as a function of antenna material and manufacturing technique and the antenna performance when attached to various materials. The radio assay experiments are designed for RF tag antennas that operate in the far field of the tag reader and communicate using modulated backscatter radiation at 915 MHz. Three flexible, folded dipoles, printed on plastic substrates, were measured in the radio assay experiments. The results of the experiments include the following: the antenna gain penalty (relative to a baseline antenna) for each antenna material and manufacturing technique, the antenna gain penalty (relative to the free space antenna gain) due to material losses when the tag antenna is attached to an object, and the benefits (in terms of antenna gain) of tuning each tag antenna to the material to which it is attached. The results are presented in a form to aid RF engineers in the design of RF tag system link budgets.

Abstract:

Thesis (M. Tech.) - Central University of Technology, Free State, 2010
The main aim of this research was to automate student attendance registration, thereby reducing human involvement in the whole process. This was made possible using Radio Frequency Identification (RFID) technology. The Central University of Technology uses student cards that are compatible for use with RFID technology. As a result, no initial investment (except for the existing personal computer’s and the constructed RFID reader) in infrastructure was required for this project. The basic working of the project was as follows. The students belonging to a specific class had their vital educational data (Student number, Name) entered into a database table at the time of registration. A student card containing a serial number, with reference to the data contained in the database table, was given to the students after registration. The students walk into their respective classes and scan their student cards with the RFID reader. The serial number stored in the student card is transferred to the reader and from there wirelessly to the main server using ZigBee technology. In the main server, using Java programming language, the card serial number is sent to the Integrated Development Environment (IDE). In this project the Netbeans IDE (Java platform) was used. The Netbeans IDE is connected to the Apache Derby database using Java Database Connector (JDBC), so the serial number (which is referenced to the educational data of the students) from the student card is automatically compared with the original database created at the time of registration. Once a match is confirmed between the two entries, the data is entered into a separate database table which serves as the basic attendance sheet for a specific day.

Abstract:

In large warehouses, there are a lot of articles that needs do be kept track of. As the number of articles grows larger, the administrative complexity increases. Thus, a solution that automatically keeps track of the position of each article in real-time is of interest. That is, if an item in the warehouse is moved, no manual administration should be needed to know the new position of the item. Radio detection and ranging (RADAR) is a ranging technique that doesn’t need to communicate with an object to find the distance to it, instead signals are sent and when they are reflected off the object and returned to the sender, the distance to the object may be calculated. However, you cannot tell two equally shaped objects apart purely based on RADAR techniques. There are many other techniques for ranging, sound navigation and ranging (SONAR) is another example, but they all lack the possibility of detecting the identity of the object. So, in order to find a specific item’s position, some kind of communication with the item is necessary. Radiofrequency identification (RFID) is a neat technology with which this is possible. An RFID reader can send radio signals out in the air, and objects that are in the vicinity of the reader and are tagged with an RFID tag can receive that signal and respond with it’s unique identification number. This way, the RFID reader can identify the RFID tagged object from a distance. There are also a variety of ways to approximate the distance between reader and tag. Unfortunately this is a rather difficult task, especially in indoor environments. There are already some existing products on the market that uses RFID for different kinds of positioning. In this thesis, the theory behind positioning, the fundamentals of RFID and different positioning solutions will be analysed and presented. A number of tests were carried out with an RFID system within the ultra-high frequency (UHF) band, which is around 866 MHz. The test system only supported range estimation based on the received signal strength indicator (RSSI) and the test results showed that narrowband RSSI measurements are highly disturbed by multipath propagation which make the overall positioning performance insufficient. Further analysis of time based range estimation techniques, such as time of arrival (TOA), time of flight (TOF) and time difference of arrival (TDOA), revealed that better positioning accuracy is possible, especially if ultra-wide bandwidth (UWB) is used.

Abstract:

The application of Radio Frequency Identification (RFID) technology in hospitals is modest primarily due to cost and policy issues. Similar to the evolution of other electronic technologies, unit costs for components have been dramatically reduced in the past few years. Despite the reduction in costs, RFID technology has not yet achieved the tipping point of economic rationality for adoption at most healthcare organizations. Although the technology has been primarily applied to asset management and supply chain applications, Navy Medicine stands to gain tremendous benefit if this technology could be successfully implemented for staff and patient tracking in addition to inventory management. The purpose of this thesis was to conduct a review of RFID technology and components that could fit into the Navy Medicine's structure. The study explored the implementation requirements associated with the deployment in other industries that could be used as benchmarks for Navy Medicine implementation. Different technological architectures were described to illustrate the various techniques that could be used for creating the opportunity to automate administration, reduce errors and improve security for both patients and staff.

Abstract:

In the last decade, Radio Frequency Identification (RFID) technology has been widely used in industries for controlling and monitoring purposes but has limited application in supply chain management. Passive tags are used in commercial offices for access control, while a more active and powerful tag is deployed in highways for electronic road toll collections. Other non-contact, close range methods are popular in subways and other public transport systems. The use of RFID in supply chain management is an emerging technological trend that has attracted a lot of attention in the U.S., Europe, and Asia. This is largely driven by the potential benefits that RFID technology is perceived to deliver in the supply chain, particularly, supply chain visibility. Major retailers and leading corporations around the globe are already testing and implementing RFID, and claiming to have achieved competitive advantages and return on their investments. It is, therefore, important to understand the adoption of RFID in New Zealand supply chains, so that appropriate actions can be taken to ensure that New Zealand companies are not lagging behind. This research study explores and explains the adoption of RFID in supply chains using exploratory survey and case study. The research questions are: 1. What specific benefits can be achieved in organisations by using RFID? 2. What are the barriers to realising these benefits? 3. How and why do organisations adopt or not adopt RFID in supply chains? Three factors were found to be important in the adoption of RFID in New Zealand supply chains. They are the compatibility of RFID with existing organisation's systems and values, the availability of supports to facilitate RFID adoption, and the readiness of the internal and external organisation's environment. It was also found that complexity of the technology and the relative advantage of using RFID were to a certain extent influencing users' perception of RFID compatibility. Dependency on trading partners was found to have some effects on RFID adoption. A theoretical framework of RFID adoption in supply chains is proposed. This framework helps to bring out the important factors in the adoption of RFID in supply chains. While most IS research is focused on individual technology adoption or on intra-organisational technology adoption, this research is focused on technology adoption that involves or has impacts on trading partners, that is, at supply chain level. It provides a three-dimensional evaluation framework which includes technological, organisational, and environmental aspects of inter-organisational technology adoption.

Radio Frequency Identification (RFID) is a wireless technology that can be used to track inventory labeled with microchip-embedded identifiers communicating passively with scanners without operator involvement. This non-line-of-sight technology has the potential of dramatically increasing the level of visibility throughout the supply chain for many types of products, assisting in defect reduction, increased granularity in inventory tracking, and decreased direct labor. In recent years, developments in RFID technology have decreased the cost of RFID equipment, and several large U.S. retailers have started to use RFID to track consumer products. However, what is not clear is whether or not these RFID implementations have yielded economic returns. Although RFID promises higher read rates and increased accuracy, how the technology works in particular warehouse settings is not clear. The first step to determining the feasibility of RFID in any organization is the complete evaluation of RFID technology. This document discusses an evaluation strategy using the Six Sigma DMADV framework. The strategy was carried out at internet retailer Amazon.com.
(cont.) The document discusses the various steps required for a complete implementation of the evaluation strategy and refers to the evaluation at Amazon.com as a case study. The purpose of this document is to recommend a complete evaluation strategy of RFID system components for any customer fulfillment center that is thinking of implementing this technology to replace existing tracking technologies such as bar code or other manual forms of tracking.

Abstract:

This thesis extends the use of Radio Frequency Identification (RFID) data for accounting of warehouse costs and services. Time Driven Activity Based Costing (TDABC) methodology is enhanced with the real-time collected RFID data about duration of warehouse activities. This allows warehouse managers to have an accurate and instant calculations of costs. The RFID enhanced TDABC (RFID-TDABC) is proposed as a novel application of the RFID technology. Application of RFID-TDABC in a warehouse is implemented on warehouse processes of a case study company. Implementation covers receiving, put-away, order picking, and despatching. RFID technology is commonly used for the identification and tracking items. The use of the RFID generated information with the TDABC can be successfully extended to the area of costing. This RFID-TDABC costing model will benefit warehouse managers with accurate and instant calculations of costs. Although the study is limited in the scope to applying presented RFIDTDABC model only to warehouse operations of a SME company, RFIDTDABC concept will be of value to both academics and practitioners by showing how warehouse costs can be accurately measured by using this approach. Providing better understanding of incurred costs may result in a further optimisation of warehousing operations, lowering costs of activities, and thus provide competitive pricing to customers.

Abstract:

Personal robots with autonomy, mobility, and manipulation capabilities have the potential to dramatically improve quality of life for various user populations, such as older adults and individuals with motor impairments. Unfortunately, unstructured environments present many challenges that hinder robot deployment in ordinary homes. This thesis seeks to address some of these challenges through a new robotic sensing modality that leverages a small amount of environmental augmentation in the form of Ultra High Frequency (UHF) Radio-Frequency Identification (RFID) tags. Previous research has demonstrated the utility of infrastructure tags (affixed to walls) for robot localization; in this thesis, we specifically focus on tagging objects. Owing to their low-cost and passive (battery-free) operation, users can apply UHF RFID tags to hundreds of objects throughout their homes. The tags provide two valuable properties for robots: a unique identifier and receive signal strength indicator (RSSI, the strength of a tag's response). This thesis explores robot behaviors and radio frequency perception techniques using robot-mounted UHF RFID readers that enable a robot to efficiently discover, locate, and interact with UHF RFID tags applied to objects and people of interest. The behaviors and algorithms explicitly rely on the robot's mobility and manipulation capabilities to provide multiple opportunistic views of the complex electromagnetic landscape inside a home environment. The electromagnetic properties of RFID tags change when applied to common household objects. Objects can have varied material properties, can be placed in diverse orientations, and be relocated to completely new environments. We present a new class of optimization-based techniques for RFID sensing that are robust to the variation in tag performance caused by these complexities. We discuss a hybrid global-local search algorithm where a robot employing long-range directional antennas searches for tagged objects by maximizing expected RSSI measurements; that is, the robot attempts to position itself (1) near a desired tagged object and (2) oriented towards it. The robot first performs a sparse, global RFID search to locate a pose in the neighborhood of the tagged object, followed by a series of local search behaviors (bearing estimation and RFID servoing) to refine the robot's state within the local basin of attraction. We report on RFID search experiments performed in Georgia Tech's Aware Home (a real home). Our optimization-based approach yields superior performance compared to state of the art tag localization algorithms, does not require RF sensor models, is easy to implement, and generalizes to other short-range RFID sensor systems embedded in a robot's end effector. We demonstrate proof of concept applications, such as medication delivery and multi-sensor fusion, using these techniques. Through our experimental results, we show that UHF RFID is a complementary sensing modality that can assist robots in unstructured human environments.

After the terrorist attacks of 9/11 US realized the importance of building and maintaining a secure environment that would protect US borders. The significance of having a secure supply chain in the US is apparent, since the amount of cargo containers that enters US borders through ports is at an all time high. To ensure that, US government bought a new set of policies which have as their main purpose to ensure that the shipments that will enter its borders will not jeopardize US public, but also maintain the smooth operation of country's trade relations after unforeseen events. This legal framework encourages the application of tracking applications/solutions that could provide visibility and security across the supply chain. One of the promising technologies that allows tracking of shipping containers, from their origin to destination is the application of Active RFID tags in a network that would allow tracking of the container movement on an end-to-end basis. Through this study, we examine the parts and operation of such a solution, the parts and main characteristics of this technology. We set forth the potential benefits and the potholes that could make at the moment such a solution to fail, if the industry does not try to repair the systems faults and shows overconfidence in the proposed technology.

Abstract:

Radio Frequency IDentification (RFID) is a wireless communications technology which allows companies to secure their assets and increase the portability of information. This research was motivated by the increased commercial use of RFID technology. Existing security protocols with high levels of security have high computation requirements, and less intensive protocols can allow a tag to be tracked. The techniques proposed in this thesis result in the increase of ciphertexts available without a significant increase in processing power or storage requirements. The addition of random inputs to the generation of ciphertexts will increase the number of possible results without requiring a more advanced encryption algorithm or an increased number of stored encryption keys. Four methods of altering the plaintext/ciphertext pair (random block, set pattern, random pattern, and indexed placement) are analyzed to determine the effectiveness of each method. The number of ciphertexts generated, generation time, and generation errors were recorded to determine which of the four proposed methods would be the most beneficial in a RFID system. The comparison of these method characteristics determined that the set pattern placement method provided the best solution. The thesis also discusses how RFID transmissions appear to attackers and explains how the random inputs reduce effectiveness of current system attacks. In addition to improving the anonymity of RFID tag transmissions, the concept of authenticating random inputs is also introduced in this thesis. These methods help prevent an adversary from easily associating a tag with its transmissions, thus increasing the security of the RFID system.

MBA Professional Report
The purpose of this MBA project is to identify the potential value of Radio Frequency Identification (RFID) used for inventory and asset management at the Tobyhanna Army Maintenance Depot. Tobyhanna Army Depot recently partnered with WhereNet Corporation for a pilot program to incorporate a real-time locating system that uses RFID. The pilot program tracks the AN/TPS-75 and AN/TRC-170 systems through the maintenance processes to determine if RFID is beneficial. The RFID asset management system proved beneficial to increase process efficiency and reduce the number of wasted labor hours used to find misplaced items. The cost-benefit analysis at the Tobyhanna Army Depot RFID pilot program indicates a Return on Investment of less than one year and supports previous research conducted on RFID as an asset management tool. Tobyhanna's investment in advancing technology essentially paid for itself within one year when measured in labor cost savings and yielded an annual savings of 837 Repair Cycle Time days. Since the primary infrastructure for RFID is already funded and fully operational, the payoff period on incremental investment is likely to be much shorter in the future.

Abstract:

Context. This thesis takes an opportunity perspective. Radio Frequency Identification technology (RFID) has showed potential in enhancing and optimizing supply chains. For Pan Nordic Logistics (PNL), this represents an interesting opportunity and a possibility to enhance goods flow, increase quality, and gain competitive advantage.

The study. This study has looked at how RFID could benefit PNL. A number of opportunities have been identified. Of these opportunities, the ‘Hub’ in Jönköping has been analyzed in further detail. The current logistics process has been mapped out in order to determine where in the logistics process the technology could have the optimal impact. Since it is not possible to perform a full financial evaluation without benchmarking and measuring the effects of RFID, a framework have been provided for future measurement, evaluation, and implementation.

Findings and recommendations. This study concludes that an RFID implementation at the ‘Hub’ in Jönköping is ‘most likely’ to be financially feasible. RFID is a promising technology that should be taken to the next level. A small-scale implementation is recommended in order to ‘try out’ the technology and to fully evaluate how it could be adapted to fit existing solutions of PNL such as computer systems. If implemented, this trial should serve to map out the financial side of the technology using the provided framework. It is currently neither possible, nor feasible to fully understand the financial impact of the technology. Such a forecast would be imprecise and possible misleading.

Radio Frequency Identification (RFID) technology, an important component in the enterprise IT infrastructure, must be integrated into the legacy IT system. This thesis studies how RFID technology can be integrated into the existing Electronic Data Interchange (EDI) infrastructure, particularly how RFID can be used in the current EDI exchange process to accelerate the receiving process. After detailed review of current receiving process and relevant data specification, the author finds it possible to replace the current manual receiving process by RFID enabled automatic receiving and reconciliation process. A middleware is proposed to implement this approach.

Abstract:

Counterfeit products, particularly pharmaceuticals, electronic devices, and apparels, are widespread. They threaten consumer safety and cause huge economic losses to licit supply chain partners and governments. Although a number of traditional anti-counterfeiting technologies, such as holograms and chemical tags, are available to combat counterfeiting, they are vulnerable to imitation or being reused. Besides, these technologies are intended to protect individual items, rather than to safeguard an entire supply chain. As such, fake products may likely be injected into the supply chain to hurt end-consumers. Track-and-trace technology based on Radio Frequency Identification (RFID) has recently emerged as a promising tool to combat counterfeiting, because of its automatic and non-line-of-sight capability to identify massive product items. By maintaining an electronic pedigree (e-pedigree) that records the transaction information of product items along the supply chain, this approach stands out for protecting the supply chain against infiltration, eliminating theft and fraud, facilitating recall of defective products, and supporting remote authentication. However, a number of technical and critical issues have yet to be solved for practical implementation of RFID-based track-and-trace anti-counterfeiting. These include generation of accurate initial product e-pedigree in fast moving manufacturing lines, precise e-pedigree updating in batch product distributing and receiving, and fast e- pedigree queries for remote and real-time product authentication from end-customers. Without fully addressing these issues, the accumulated product e-pedigree data would be untrustworthy, rendering any subsequent operations of track-and-trace and product authentication unreliable. This thesis investigates the crucial implementation issues in RFID-based track-and-trace anti-counterfeiting. It firstly presents an innovative track-and-trace anti-counterfeiting system, based on which a TDPS algorithm is proposed for generation of initial product e-pedigree in fast moving production lines. The TDPS overcomes many practical issues, such as tag writing error and tag locking failure, and helps identify the bottleneck of initial product e-pedigree generation. To tackle the bottleneck, the TDPS is further optimized by incorporating a block writing method to enhance the tag EPC writing efficiency and an integration method to balance the overhead of RFID equipment. In product distributing and receiving, a mechanized 3D scanning method is proposed to improve bulk item identification rate and enhance the accuracy and completeness of product e-pedigree. Indeed, RFID-based track-and-trace anti-counterfeiting mandates a relatively high bulk item identification rate for product authentication and e-pedigree updating. Experimental results demonstrate that the mechanized 3D scanning can achieve a bulk item reading rate of up to 98.9%, which largely outperforms the widely documented bulk reading rate (70%) in real applications. In retailing level, the efficiency of e-pedigree queries would hugely impact on customer shopping experience and the effectiveness of track-and-trace anti-counterfeiting. A partition-based method is therefore developed to cluster product e-pedigree data to improve the speed of e-pedigree queries. This approach partitions the accumulated e-pedigree data into fixed and dynamic groups, such that queries are conducted mainly on active data, rather than on the whole historical data sets. By addressing the above key issues, this thesis contributes to making implementation of RFID-based track-and-trace anti-counterfeiting practically viable and reliable.

Abstract:

A screening experiment was paired with research observing the past, present and futures of additive manufacturing (a.k.a. rapid prototyping, 3D printing), radio frequency identification, and supply chain management. The experiment tested different properties of objects created with a desktop fused deposition modelling printer to observe if any single factors or interactions affected the read range of embedded passive UHF RFID inlay. The combination of material and infill percentage had a statistically significant effect on read range, however the analysis is weak since the data could not justify the normality assumption of ANOVA. Furthermore, the size of the effect was small enough to deny any practical difference. From the experiment and research, several presently capable interactions between AM and RFID were commented on. Future interactions between AM, RFID and SCM were also discussed, and a common relationship to physical objects was drawn.
