15、C 29143:2011(E) iv ISO/IEC 2011 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 de
16、velopment 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-govern
17、mental, 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
18、 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
19、. ISO/IEC 29143 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 31, Automatic identification and data capture techniques. BS ISO/IEC 29143:2011ISO/IEC 29143:2011(E) ISO/IEC 2011 All rights reserved vIntroduction This International Standard provides an
20、 air interface specification for Mobile radio frequency identification (RFID) interrogators that are part of a passive backscatter system. This system comprises one or more mobile interrogators, also known as Mobile RFID interrogators, and an undefined number of tags, also known as labels. Interroga
21、tors are not required to support channel sensing, i.e. do not need to implement Listen Before Talk (LBT), and transmit commands on the off chance under the risk of colliding with one or more peer- interrogators. Moreover, interrogators compliant to this International Standard are not obliged to sync
22、hronize by any means (wired or wireless), i.e. no control channel dedicated to coordinating Time Division Multiplexing (TDM) is provided. Tags are powered by the RF signal provided by the interrogator and respond to an interrogator by modulating the reflection coefficient of its antenna, thereby bac
23、kscattering data to the interrogator. The working mode adopted by the tags is purely passive, i.e. tags do not actively initiate any kind of RF communication. In this International Standard, collision arbitration and collision avoidance for Mobile RFID applications are defined by specifying methods
24、aimed at mitigating the impact of emerging collisions and mechanisms used to avoid follow-up collisions. 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 i
25、nvolve the use of patents concerning radio-frequency identification technology given in the clauses identified 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 ISO and IEC that they are willing to
26、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 29143:2011ISO/IEC 29143:2011(E) vi ISO/IEC 2011 All rights reservedI

31、hnology Automatic identification and data capture techniques Air interface specification for Mobile RFID interrogators 1 Scope This International Standard applies to Mobile radio frequency identification (RFID) interrogator devices used to inventory passive or semi-passive backscatter tags at 860 MH
32、z to 960 MHz in a mobile (non-fixed) application independent from specific communication details, i.e. modulation technique and command set. Furthermore, the scope of this International Standard is mobile consumer applications, whereas mobile enterprise applications are not covered as long as operat
33、ing in a closed environment. An operating environment is considered to be closed if it belongs to a central administrative authority able to guarantee for sufficient isolation, i.e. preventing mobile enterprise interrogator devices from being used outside the dedicated operating environment, and if
34、sufficient spatial separation and/or electromagnetic shielding from adjacent operating environments is provided. An application is considered a consumer application if at least one of two interacting entities is a private individual (consumer) and the interaction is taking place in the public domain
35、. Consequently, a Mobile RFID consumer application is defined as Mobile RFID equipment (e.g. mobile phones equipped with an RFID interrogator) being used in a consumer application. NOTE As there is currently no active contribution on Mobile HF interrogators, this International Standard covers only U
36、HF. This International Standard specifies Mobile RFID interrogator media access control, interrogator to interrogator and multiple interrogator to tag collision arbitration scheme including interrogator requirements, interrogator to interrogator and multiple interrogator to tag collision avoidance s
37、cheme, and tag memory use for Mobile RFID applications. This International Standard does not specify physical interactions (the signaling layer of the communication link) between interrogators and tags, interrogator and tag operating procedures and commands, and the collision arbitration algorithm u
38、sed to singulate (separate to the current response slot) a specific tag in a multiple-tag environment. NOTE These aspects are addressed by other International Standards. In particular, this International Standard does not replace any existing RFID air interface specification issued by ISO/IEC but ex
39、tends the existing methodologies for fixed RFID interrogators with mechanisms addressing BS ISO/IEC 29143:2011ISO/IEC 29143:2011(E) 2 ISO/IEC 2011 All rights reservedthe special challenges of Mobile RFID. The concepts and mechanisms described in this International Standard can be integrated in any e
40、xisting RFID protocol approved by ISO/IEC for the given frequency range of 860 MHz to 960 MHz (unless explicitly prohibited by such protocol) regardless of the actual command set. The mechanisms defined by this International Standard can be used for Mobile RFID interrogators used in consumer applica
41、tions and compliant to ISO/IEC 18000-6. 2 Conformance To claim conformance with this International Standard, an interrogator shall comply with all relevant clauses, except those marked as “optional”. Moreover, the interrogator shall also operate within local radio regulations, which may further rest
42、rict operation. To claim conformance with this International Standard, an interrogator shall also fulfill all requirements to claim conformance with the basic air interface specification ISO/IEC 18000-6. NOTE The basic assumption is that this International Standard cannot be used standalone. It is n
43、ot intended to encourage usage of a proprietary air interface in combination with the extension defined in this International Standard and allow claiming conformance with this International Standard in that context. Mobility of the RFID interrogator device is not a requirement for claiming conforman
44、ce with this International Standard. It is recommended that all RFID interrogators operating in public areas of service, where interrogator to interrogator and multiple interrogators to tag collisions cannot be ruled out by administrative measures such as Time Division Multiplexing or Frequency Divi
45、sion Multiplexing, support the mechanisms specified in this International Standard regardless of the particular usage of the device (fixed, mobile, or both). Conformance may also require a license from the owner of any intellectual property utilized by this device. A mobile device shall only activat
46、e its RF for RFID capabilities if it is established that it operates according to the RF regulations of the country where it is turned on. For mobile phones this implies that the phone shall derive the country of operation from the network before activating the RF capabilities for RFID. 3 Normative
