National bodies that are members of ISO or IEC participate

19、 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

20、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 ma

21、in 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 cast

22、ing a vote. ISO/IEC 18000-61 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 identi

26、C 18000 describes a passive backscatter radio frequency identification (RFID) system that supports the following system capabilities: identification and communication with multiple tags in the field; selection of a subgroup of tags for identification or with which to communicate; reading from and wr

27、iting to or rewriting data many times to individual tags; user-controlled permanently lockable memory; data integrity protection; Interrogator-to-tag communications link with error detection; tag-to-Interrogator communications link with error detection; support for both passive back-scatter tags wit

28、h or without batteries. This part of ISO/IEC 18000 specifies the physical and logical requirements for a passive-backscatter, RFID system operating in the 860 MHz to 960 MHz frequency range. The system comprises Interrogators, also known as readers, and tags, also known as labels. An Interrogator tr

29、ansmits information to a tag by modulating an RF signal in the 860 MHz to 960 MHz frequency range. The tag receives both information and operating energy from this RF signal. Passive tags are those which receive all of their operating energy from the Interrogators RF waveform. If tags maintain a bat

30、tery then they may operate using some passive principles; however, they do not necessarily get all their operating energy from the Interrogators RF waveform. An Interrogator receives information from a tag by transmitting a continuous-wave (CW) RF signal to the tag; the tag responds by modulating th

31、e reflection coefficient of its antenna, thereby backscattering an information signal to the Interrogator. The system is Interrogator-Talks-First (ITF), meaning that a tag modulates its antenna reflection coefficient with an information signal only after being directed to do so by an Interrogator. I

32、nterrogators and tags are not required to talk simultaneously; rather, communications are half-duplex, meaning that Interrogators talk and tags listen, or vice versa. The International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC) draw attention to the fa

33、ct that it is claimed that compliance with this document may involve the use of patents concerning radio frequency identification technology. ISO and IEC take no position concerning the evidence, validity and scope of these patent rights. The holders of these patent rights have assured ISO and IEC t

34、hat 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. BS ISO/IEC 18000-61:2012ISO/IEC 18000-61:2012(E) ISO/IE

In detail, this part of ISO/IEC 18000 contains Type A. Type A is ITF. Type A uses Pulse-Interval Encoding (PIE) in

37、the forward link and an adaptive ALOHA collision-arbitration algorithm.
