IEEE RFID 2011 is excited to announce the opportunity to learn from some of the leading experts in the field in an interactive and hands-on environment. Whether you’re keen on understanding what goes on under the hood of an RFID reader, how the state of the art in RFID based localization will impact your inventory management or looking to understand the ABC’s of an RFID system, our pre-conference tutorial and workshops day has a lot to offer you:
Workshop 1: Reader Essentials (April 12: 8:30-12 noon)
Organizer: Matt Reynolds, Professor at Duke University, Former CTO ThingMagic
Participants will learn how to design and build their own passive or semi-passive UHF RFID reader. Participants will observe working test setups and observe live signals from both passive and semi-passive tags. This workshop demystifies the RFID reader and demonstrates how one can be effectively built at modest cost.
• Review of UHF RFID link budgets in passive,
semi-passive, and near-field modes
• Metrics of interest for UHF RFID systems
• System modeling using Agilent ADS
• Signal sources, modulators, demodulators, and
• DSP software using MATLAB
• Emulator tags and WiSPs
• Monostatic readers and BAP tags
• Reader test setups that can be built at modest cost
• Live demos of test setups and measurements
Workshop 2: Localization in UHF RFID (April 12: 1pm – 4:30 pm)
[Presentation Slides may be accessed here]
Organizers: Daniel Arnitz & Klaus Witrisal, Graz Univ of Tech; Pavel Nikitin, Intermec Technologies
UHF RFID tag localization in the real world is a challenging problem. After outlining several different localization techniques and associated challenges, our panel of industry and academic experts will share their experiences in working UHF RFID based localization.
Introduction and Basics (15 min)
• UHF RFID Channel Analysis and Simulation Recommendations (45 min); Daniel Arnitz, Graz Univ. of Technology
• Ranging Methods Overview (45 min); Pavel Nikitin, Intermec Technologies
• Market Requirements, Applications, and Use Cases (30 min); Justin Patton, RFID Research Center, Univ. of Arkansas
• Working UHF RFID Localization Systems (60 min); Zhuo Zou, Royal Institute of Technology, Sweden; Lyazid Aberbour, University of Louvain, Belgium; Chris Hook and Joe Leone, RF Controls / SAIC, USA
Tutorial: The Basics of UHF RFID or Radiating without a License (April 12: 8:30 am – 4:30 pm)
Presenter: Dan Dobkin, Principal, Enigmatics Consulting, Author of “The RF in RFID”
This tutorial will cover a brief history of RFID and applications of RFID technology including the basic types of passive, semi-passive/active, active; systems operating at low frequency, high frequency, and ultra-high frequency; and live demonstrations. Other topics to be covered are: RFID technology essentials such as signals, voltage and power, information and modulation, path loss for an isotropic transmitter, link budgets for passive and semi-passive (BAT) tags, antenna directivity, polarization, and patterns, link budget, forward and reverse link-limited range readers, LLRP, protocols in general, Gen 2 / ISO 18000-6C standard, ISO 18000-6:2010 extensions, transmitters and RF spectrum, receiver design challenges, and antenna configurations. Topics on RFID tags include: packaging, passive tag antennas, power harvesting, active tags, and tag IC challenges.
This 7-hour primer on the basics of UHF RFID is ideal for conference attendees, students, researchers, and engineers just starting to investigate RFID technologies, devices, and systems, as well as technicians, project managers, and less-technical marketing, sales, and executives wishing to enhance their theoretical knowledge and understanding of core RFID elements.
