20、 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 particu
21、lar 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 establi
22、shed 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 technica
23、l 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 18000-64 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 31, Automatic
24、 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 int
25、erface 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 General Part 61: Parameters for air interface communications

28、tification and communication with multiple tags in the field; reading from individual tags; data integrity protection; tag-to-Interrogator communications link with error detection; support for both passive back-scatter tags with or without batteries. This part of ISO/IEC 18000 specifies the physical
29、 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 a continuous-wave (CW) RF signal in the 860 MHz to 960 MHz freque
30、ncy range. The tag receives operating energy from this RF signal and responds by modulating the reflection coefficient of its antenna, thereby backscattering an information signal to the Interrogator. Passive tags are those which receive all of their operating energy from the Interrogators RF wavefo
31、rm. If tags maintain a battery then they may operate using some passive principles; however, they do not necessarily get all their operating energy from the Interrogators RF waveform. This part of ISO/IEC 18000 contains an optional Tag Only Talks After Listening (TOTAL), an enhanced Tag Talks Only (
32、TTO) technique. A Type D tag shall announce itself when it detects CW emitted by an Interrogator, only after it has detected the absence of ITF modulation as defined in ISO/IEC 18000 part 6. Type D uses Pulse-Position Encoding (PPE) or Miller encoding in the return link and does not define a dedicat
33、ed forward link. Tags may implement a forward link of one of the types defined in ISO/IEC 18000 part 6 in order to allow enhanced tag access techniques. The International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC) draw attention to the fact that it is
34、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 that they are w
35、illing 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 18000-64:2012 ISO/IEC 18000-64:2012(E) ISO/IEC 2012 All ri

37、rmation signal to the Interrogator. The system is TOTAL, meaning that a tag modulates its antenna reflection coefficient with an information signal upon entering an Interrogators field after first listening for Interrogator modulation in order to determine if the system is ITF or not. In detail, thi
38、s part of ISO/IEC 18000 contains Type D. Type D is TOTAL based on Pulse Position Encoding or Miller M=2 encoded subcarrier. This part of ISO/IEC 18000 specifies physical interactions (the signalling layer of the communication link) between Interrogators and tags, Interrogator and tag operating proce
39、dures, the collision arbitration scheme used to identify a specific tag in a multiple-tag environment. 2 Conformance 2.1 Claiming conformance To claim conformance with this part of ISO/IEC 18000, an Interrogator or tag shall comply with all relevant clauses of this part of ISO/IEC 18000, except thos
40、e marked as “optional”. The Interrogator or tag shall also operate within local radio regulations, which can further restrict operation.

43、 enhanced tag access techniques. 2.3 Tag conformance and obligations To conform to this part of ISO/IEC 18000, a tag shall: support Type D; operate over the frequency range from 860 MHz to 960 MHz, inclusive; modulate a backscatter signal only after listening for the absence of ITF modulation; and c
