http://grifs-project.eu/db/ In a chain that reaches from object to data bank, there are many links. - The object should have a unique tag.
- The UID should be stored in a tag.
- The Tag should have certain characteristics.
- The Tag should be able to talk to a reader (and/or a writer)
- The Reader should be connected to a Control Unit.
- The Unit should impart the underlying system.
- Etc
All links are candidates for standardization. Some are critical, others are only desirable.. THE PRESENT POSITION EPCglobal has recently approved ”Generation 2” of its regulations that covers storage information, air boundary beacons (including frequencies) as well a part of reader’s functionality. At the present time specifications are only available to EPCglobal license holders. Certain parts of it are already the subject of an infringement of patent law suit. As soon as the copyright problems are solved they have promised to send in the specs to the ISO system process. EPCglobal is also aiming at standards for the rest of the RFID based system ETSI the European telecom standards organ, has published a specification for the use of RFID on the frequency band 865-868 Mhz. Right now the ”specs” making their way through translation amongst other things and will be published as a European norm (EN). After that, member countries (including Sweden) have 3 months grace to replace the eventual conflicting national standards. According to PTS a special license is still required for applications in the frequency band. Within ISO/IEC there are many standards that touch upon RFID. Most of them are published and stable and manage the number in the tag up to the reader. The one that is most discussed is the ISO/IEC s the 18000-6, which regulates the boundary beacons within the so called 900 MHz-band, that is to say the one that is employed by EPCglobal. Neither of the two tag architecture (A and B) fit the EPC. Apart from that, the ISO has recently started an activity to standardize the reader boundary beacon upstream.
