15、SO/IEC 2012 All rights reservedForeword 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 Interna
16、tional 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 w
17、ith 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
18、 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 18000-62 w
19、as 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:
20、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

22、C Part 64: Parameters for air interface communications at 860 MHz to 960 MHz Type D Part 7: Parameters for active air interface communications at 433 MHz BS ISO/IEC 18000-62:2012 ISO/IEC 18000-62:2012(E) ISO/IEC 2012 All rights reserved vIntroduction This part of ISO/IEC 18000 describes a passive ba
23、ckscatter 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 writing to or rewriting data man
24、y 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 with or without batteries. This p
25、art 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 transmits information to a tag b
26、y 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 battery then they may operate usi
27、ng 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 the reflection coefficient of it
28、s 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. Interrogators and tags are not
29、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 fact that it is claimed that com
30、pliance 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 that they are willing to negoti
31、ate 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 18000-62:2012 ISO/IEC 18000-62:2012(E) vi ISO/IEC 2012 All rights reserved

Contact for license application Name the tag responds by modulating the reflection coefficient of its antenna, thereby backscattering an information signal to the Interrogator. The system
33、 is ITF, meaning that a tag modulates its antenna reflection coefficient with an information signal only after being directed to do so by an Interrogator. In detail, this part of ISO/IEC 18000 contains Type B. Type B uses Manchester in the forward link and an adaptive binary-tree collision-arbitrati

The Interrogator or tag shall also operate within local radio regulations
36、, which can further restrict operation. Relevant conformance test methods are provided in ISO/IEC TR 18047-6. Conformance can also require a license from the owner of any intellectual property utilized by said device. BS ISO/IEC 18000-62:2012 ISO/IEC 18000-62:2012(E) 2 ISO/IEC 2012 All rights reserv
