Standardisation in RFID Alfio Grasso Deputy Director, Auto-ID Lab, Adelaide General Manager, RFID Automation
Overview • RFID Background • EPCglobal • Standards Development Process • Workgroups • Technical Standards • Hardware Action Group • Software Action Group • Standard’s Documents • ISO Standards • 18000-1 to -7 • Others • Regulatory Standards • FCC, ETSI, Australian 4W RFID licence • Auto-ID Lab, Adelaide RFID World 2005 Workshop - Standardisation in RFID
Why now for RFID? • RFID invented in WWII • Steady development over last 50+ years • Recent improvements in tag and reader technology • Better performance • Easier deployment and maintenance • Better use of existing infrastructure and technologies • Improvements in tag and reader manufacturing • Cheaper tags and readers • Industry standardisation • EPCglobal and ISO RFID World 2005 Workshop - Standardisation in RFID
RFID • Radio Frequency Identification • Automatic Data Capture • Uses RF to communicate • Basic Elements • Tags • Readers/Antennas • Host CPU RFID World 2005 Workshop - Standardisation in RFID
Tag reading The black spot Reader Tx typically 1W, 6dB gain Antenna But propagation loss, resulting Rx at Tag typically µW On tag, RF energy used for DC power and modulation More loss back to Reader Rx Therefore a very weak reply is obtained RFID World 2005 Workshop - Standardisation in RFID
RFID Tags • Tags • Attached to objects or items • Contains electronics (chip), and antenna • Most are passive (no power source) • Active tags have a battery RFID World 2005 Workshop - Standardisation in RFID
Matrics (Symbol) Tags RFID World 2005 Workshop - Standardisation in RFID
Alien Technology Tags RFID World 2005 Workshop - Standardisation in RFID
Intermec Tags RFID World 2005 Workshop - Standardisation in RFID
RFID Readers • Readers • Contains electronics, Tx, Rx and control • Connected to antenna(s) • mostly external • Energise tags (passive tags) • Commands tags (wake up active tags, enables management of the tag population) • Receive tag replies RFID World 2005 Workshop - Standardisation in RFID
RFID Readers RFID World 2005 Workshop - Standardisation in RFID
RFID Antenna(s) RFID World 2005 Workshop - Standardisation in RFID
Host CPU • Application • Do something with the tag information • Potential to generate massive amounts of data • Once installed it costs virtually NOTHING to read a tag! • Real time data => real time decisions • OHIO (Zero Human Involvement Operations)* * Term defined by John Greaves, CHEP International RFID World 2005 Workshop - Standardisation in RFID
