18、rganization 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

19、 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 inf

20、ormation 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 Internat

21、ional 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. Attention is drawn to the possibility that some of the elements of this document m

22、ay be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC 18046-2 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 31, Automatic identification and data capture techniques. This

23、 first edition of ISO/IEC 18046-2, together with ISO/IEC 18046-1 and ISO/IEC 18046-3, will cancel and replace ISO/IEC 18046:2006. ISO/IEC 18046 consists of the following parts, under the general title Information technology Radio frequency identification device performance test methods: Part 1: Test

24、 methods for system performance Part 2: Test methods for interrogator performance Part 3: Test methods for tag performance BS ISO/IEC 18046-2:2011ISO/IEC 18046-2:2011(E) ISO/IEC 2011 All rights reserved vIntroduction Radio frequency identification (RFID) technology has broad applicability to the aut

25、omatic identification and data capture (AIDC) industry in item management. As a wireless communication technique based on radio frequency technology, the applications cover multiple levels of the industrial, commercial and retail supply chains. These can include freight containers, returnable transp

26、ort items (RTI), transport units, product packaging, and product tagging. Performance tests define test methods that deliver results that allow the comparison of different RFID systems, interrogator and tags in order to select among them for use in a particular application. The performance character

27、istics of devices (tags and interrogation equipment) can vary drastically due to application factors as well as the particular RFID air interface (frequency, modulation, protocol, etc.) being supported. Of key concern is the matching of the various performance characteristics to the user application

28、. Additionally, in an open environment, users of such technology demand multiple sources for these devices from technology providers. A key challenge is a method of evaluating the differences between various technology providers products in a consistent and equitable manner. This part of ISO/IEC 180

29、46 provides a framework for meeting the above noted concern and challenges. To this end, clear definitions of performance as related to user application of RFID technology in the supply chain are provided. Based on such application-based definitions, test methods are defined with attention to the te

30、st parameters required for a consistent evaluation of RFID devices. Of particular significance, these tests are defined for RFID devices having one antenna. It is common practice to have products with both single and multiple antennas to define an RFID transaction zone sufficient for the application

31、. The defined test methods used are for a single antenna, but can equivalently be extended to equipment with multiple antennas, in order to evaluate performance under conditions more closely matching those of a particular application. However care must be exercised in multiple-antenna measurement si

32、nce multiple antennas can cause antenna-to-antenna interactions, physical packaging limitations, mutual coupling issues, shadowing issues, directivity issues and other impacts, even with respect to interrogators since these can be limited in size, shape, and mounting method for many RFID application
