CASAGRAS Open Seminar 1th December 2008, Shanghai The role of RFID within the Internet of Things Eldor Walk, FEIG Electronic GmbH
RFID and the Internet of Things • Introduction and Definitions • Applications • RFID Key Characteristics • Categories of RFID Systems • Standards and Regulations • Summary
Introduction and Definitions Radio Frequency Identification Radio frequency or wireless communication used for identification purposes Internet of Things refers to a network of real world or real world related objects RFID connects the real world to the Internet
Applications CE RFID, a project funded by the European Commission, developed the RFID Reference Model The RFID Reference Model • Designed to structure RFID applications • Differentiates RFID application fields as “mainly object tagging” and “tagging with reference or potential reference to individuals” • Model defines 40 RFID applications (called “subcategories”) summed up to 8 “Application Fields”
A. Logistical Tracking & Tracing B. Production, Monitoring, Maintencance C. Product Safety, Quality, Information D. Access Control, Tracking & Tracing E. Loyalty, Membership, Payment F. eHealth Care G. Sport, Leisure, Household H. Public Services The RFID Reference Model

Applications Library • Inventory management • Self checkout and return of books and media • Remote check of availability
Applications Logistics • Tracking and tracing • Inventory management • Automated goods receiving and shipment
Applications Health care • Real-time inventory management • Monitoring of equipment • Patient safety
Applications Public transport • Electronic fare management • Toll collection • Airline baggage tracking
RFID and the Internet of Things • Introduction and Definitions • Applications • RFID Key Characteristics • Categories of RFID Systems • Standards and Regulations • Summary
RFID Key Characteristics related to the Internet of Things • Wireless connection • Object-connected data
Wireless connection • Information exchange by electromagnetic radio link • Allows mobility of connected objects • Basically no line of sight is necessary to be connected • Multiple simultaneous connections • Different frequency bands, UHF and HF, offer different properties
System Characteristics and Environmental Effects • Communication zones • Reflection • Penetration • Multiple reading
Communication zones Basic layout of communication zones • Inductive system, e.g. 13.56 MHz • Antenna • Electromagnetic system, e.g. UHF
Reflections • Communication zone • of an UHF system • without reflections • side view • top view Communication zone with ground reflections
Penetration • No necessity of line-of-sight • Limited by absorption effects Multiple Reading
Object-connected data • Simple RFID tags carry only an identification code • More sophisticated tags can carry any kind of digital data and content.
Object-connected data support the management or processing of any kind of a variety of entities • Raw material • Components • Sub-assemblies • Products • Packages • Pallets • Containers • Animals and human beings
RFID and the Internet of Things • Introduction and Definitions • Applications • RFID Key Characteristics • Categories of RFID Systems • Standards and Regulations • Summary
Categories of RFID Systems • Passive RFID tags • Active RFID tags • Sensor tags • Sensor nodes • Combination of RFID and other technologies
Passive RFID tags Two main components • Fixed or variable data memory • Radio frontend
Active RFID tags Additional components • Battery • Processing Unit
Sensor tags Important components • Sensor • A/D converter
Sensor nodes • Sensor tag plus a microcontroller • Communication links to other sensor nodes and readers
Combination of RFID and other technologies • Mobile RFID applications • Information services • Mobile payment
RFID and the Internet of Things • Introduction and Definitions • Applications • RFID Key Characteristics • Categories of RFID Systems • Standards and Regulations • Summary
Standards and Regulations • Categories • Important IoT related standards and regulations • Challenges
Categories of Standards and Regulations Regulation • Regional or national regulations, directives, decisions Standards • Air interface protocols • Data standards • Network standards • Application standards
Important IoT related Standards • Frequency specifications and air interface protocols • Tag data standards such as identifiers and codes • Network standards (naming, addressing and querying the real world)
Challenges • Adequate frequency spectrum for passive and active tags, sensor tags and sensor networks • Interoperability between different edge technologies like RFID and barcode • Interoperability between data structure and network standards of different formal and industry standardisation organisations • Suitable security standards and guidelines. Different application areas need a different level of security.
RFID and the Internet of Things • Introduction and Definitions • Applications • RFID Key Characteristics • Categories of RFID Systems • Standards and Regulations • Summary
The role of RFID within the Internet of Things • Enabling technology for the “Internet of Things” • RFID connects the Internet to the real world • RFID makes items “smart” and able to communicate with their environment • RFID is a framework for a wide range of applications
