  1. Regulations, Standards and Protocols

  2. RFID systems are Radio Systems • The function of other radio systems must not be disrupted • Restriction on the range of available frequencies • ISM (Industrial-Scientific-Medical) frequency ranges • All frequencies below 135 kHz • ISM frequencies: 13.56MHz, 27.125MHz, 40.68MHz, 433.92 MHz, 890MHz, 915MHz, 2.45GHz, 5.8 GHz, 24.125GHz Source: RFID Handbook

  3. Standards • RFID standards deal with: • the air interface protocol (the way tags and readers communicate) • data content (the way data is organized or formatted) • conformance (ways to test that products meet the standard) • applications (how standards are used on shipping labels, for example).

  4. International Organization for Standardization (ISO) • ISO has created standards for tracking animals with RFID • ISO 11784 defines how data is structured on the tag. • ISO 11785 defines the air interface protocol. • ISO 14223 defines the “Advance Transponders” standard • ISO has created a standard for the air interface protocol for RFID tags used in payment systems and contactless smart cards (ISO 14443) and in vicinity cards (ISO 15693). • It also has established standards for testing the conformance of RFID tags and readers to a standard (ISO 18047), and for testing the performance of RFID tags and readers (ISO 18046). source: RFID Journal

  5. Air-Interface Protocols • High-frequency (HF) RFID air-interface protocols have a single operating frequency (13.56 MHz) but none are compatible. • These protocols include ISO 14443A, ISO 14443B, ISO 15693, ISO 18000-3 Mode 2 and EPCglobal HF Class 1. • Each has its own data structures, requires infrastructures that are incompatible • different memory map • different timing • This results in a proprietary platform rather than a standards-based model. Source: RFID Journal • Some ISO Standards

  6. History of UHF Standards • The ISO created standards for tracking goods through the international supply chain with RFID. • Auto-ID Center, which developed Electronic Product Code technologies, created its own air interface protocol for tracking goods through the international supply chain. • The Auto-ID Center developed its own protocol and licensed it to EPCglobal on the condition that it be available royalty-free. • In 2004, EPCglobal began developing a second-generation protocol Gen 2, which would not be backward compatible with earlier Class 1 or Class 0. • EPCglobal's Gen 2 standard could be submitted to ISO under 18000-6, but it's not clear when that will happen or how quickly it will be approved Source: RFID Journal

  7. UHF Gen 2 • RFID's only worldwide standard • With UHF Gen 2, reader and tag manufacturers have products that operate at all regional UHF frequencies using the same communications protocol. • Features secure memory modules and the ability to permanently kill a tag. • The whole story
