2. Storia dell’RFID
o La tecnologia RFID è stata utilizzata per la prima volta dalla RAF
durante la prima guerra mondiale per scopi di IFF (Identification
Friend or Foe)
o Anni 70 – Identificazione di materiale in aree radioattive
o 1977 – I laboratori Los Alamos rendono la tecnologia di pubblico
dominio
o Anni 80 – I primi tag passivi e le prime applicazioni in ambito
commerciale
o 2000 – I primi standard e l’interesse delle grandi aziende
4. Principi di funzionamento
• Il reader trasmette e riceve simultanemente
• Il tag prende l’energia dalla trasmissione del reader
• Il tag modula la sua impedenza di antenna che cambia la
potenza di backscatter
6. The Great Seal Bug
• Regalato nel 1946 da una scolaresca
sovietica all’ambasciatore USA
• Scoperto solo nel 1952
• Tra i primi esempi di tecnologia
backscatter
• Attivazione attraverso un campo a
radiofrequenza esterno, quasi
impossibile da rilevare
• Principio di funzionamento molto simile
alla moderna tecnologia UHF RFID

8. LF/HF vs. UHF
• Accoppiamento magnetico
• Freq. op. 130 kHz - 13.56 Mhz
• Distanza di lettura < 1 mt.
• Velocità di lettura limitata
• Forte influenza dei metalli
• Accoppiamento elettromagnetico
• Freq. operativa 860 - 960 MHz
• Distanza di lettura > 3 mt.
• Alta velocità di lettura
• Moderata influenza dei metalli

RFID Standardization Bodies - I
• ETSI – European Telecommunication Standards Institute. Its
role is to harmonize the usage of frequencies in Europe
ISO – International Organization for Standardization. Its role is
to define protocols and interfacing modes according to
harmonized frequencies (in Europe: ETSI)
International Telecommunication Union - Organization
within the United Nations System where governments
and the private sector coordinate global telecom
networks and services

RFID Standardization Bodies - II
• EPC Global. A Private company that holds the Intellectual
Properties of the EPC project. Born in 2003 as a joint
venture between EAN (European Article Numbering) and
UCC (Uniform Code Council)
Auto-ID Center. An M.I.T. Boston research group that
created the EPC project (Electronic Product Code)
GS1 (EAN-International - European Article Numbering).
Industrial Association in charge of assigning identification
numbers to products and companies worldwide

Communication Protocols
Two main standards for the Long Range RFID system (UHF) Air interface
communication (ReaderTAG and TAGReader )
ISO 18000
ISO 18000 - 3 at 13.56 MHz
ISO 18000 - 6 at 860-930 MHz
Different air interface standards based
upon the Auto-ID Center's Electronic
Product Code (EPC) referred to 13,56 MHz
e 860-930 MHz frequencies.
In Jan 2005 EPCglobal issues a new revision to overcome this standards non-
uniformity. The second-generation EPC air interface standard is formerly
known as Class 1 Generation 2 C1G2 and recently merged into ISO 18000-6C

16. EPC Electronic Product Code
The Auto-ID Center has proposed a new Electronic Product Code as the next
standard for identifying products.
Header: EPC’s version number;
EPC Mgr: 28 bits = 268,435,456 Manufacturer of the product
Object Class: 24 bits = 16,777,216 Type of product,
Serial Number: 36 bits = 68,719,476,736 unique product identifier
Each manufacturer can have 16 million object classes and 68 billion serial numbers
in each class
17. RFID Today
Long read range => new applications
Low cost of tags/label => item level
