ISO/IEC 18000-2:2004(E) Foreword ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. ISO/IEC 18000-2 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 31, Automatic identification and data capture techniques. ISO/IEC 18000 consists of the following parts, under the general title Information technology — Radio frequency identification for item management:  Part 1: Reference architecture and definition of parameters to be standardized  Part 2: Parameters for air interface communications below 135 kHz  Part 3: Parameters for air interface communications at 13,56 MHz  Part 4: Parameters for air interface communications at 2,45 GHz  Part 6: Parameters for air interface communications at 860 MHz to 960 MHz  Part 7: Parameters for active air interface communications at 433 MHz vi © ISO/IEC 2004 – All rights reserved Copyright International Organization for Standardization Reproduced by IHS under license with ISO Not for ResaleNo reproduction or networking permitted without license from IHS--`,,,,`,-`-`,,`,,`,`,,`---

ISO/IEC 18000-2:2004(E) Introduction ISO/IEC 18000 is a series of International Standards describing common communications protocols for the purpose of Radio Frequency Identification for Item Management. This part of ISO/IEC 18000 relates to systems operating at frequencies less than 135 kHz. It has been developed in accordance with the requirements determined in ISO 18000-1, Information technology — Radio frequency identification for item management — Reference architecture and definition of parameters to be standardized. The International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC) draw attention to the fact that it is claimed that compliance with this document may involve the use of patents concerning radio-frequency identification technology given in the table below. ISO and IEC take no position concerning the evidence, validity and scope of these patent rights. The holders of these patent rights have assured the ISO and IEC that they are willing to negotiate licences under reasonable and non-discriminatory terms and conditions with applicants throughout the world. In this respect, the statements of the holders of these patent rights are registered with ISO and IEC.
