11、 reserved Foreword 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 International Standards thro
12、ugh 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 with ISO and IEC, also
13、 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 committee is to prep
14、are 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. Attention is drawn to the possibility t
15、hat some of the elements of this document may 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 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 31, Automatic identif
16、ication and data capture techniques. This first edition of ISO/IEC 18046 cancels and replaces ISO/IEC TR 18046:2005, which has been technically revised. ISO/IEC 18046:2006(E) ISO/IEC 2006 All rights reserved v Introduction Radio frequency identification (RFID) technology has broad applicability to t
17、he automatic identification and data capture (AIDC) industry in item management. As a wireless communication technique based on RF technology the applications cover multiple levels of the industrial, commercial and retail supply chains. These may include freight containers, returnable transport item
18、s (RTIs), transport units, product packaging, product tagging. The performance characteristics of devices (tags and interrogation equipment) may vary drastically due to application factors as well as the particular RF air interface (frequency, modulation, protocol, etc.) being supported. Of key conc
19、ern is the matching of the various performance characteristics to the user application. 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 technol
20、ogy providers products in a consistent and equitable manner. This International Standard provides a framework for meeting the above noted concern and challenges. To this end, a clear definition of performance as it relates to user application of RFID technology in the supply chain is provided. Based
21、 on such application-based definitions, test methods are defined with attention to the test parameters that must be defined and controlled for a consistent evaluation of RFID devices. It should be noted that the test methods defined in this International Standard form the basic framework for perform
22、ance evaluation and are not exhaustive. Many applications may require a slightly different set of test conditions to match the use of RFID to the user requirements. The test methods defined herein may be modified to accommodate the specifics of the application as specified by the user. Of particular
23、 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. The defined methods can easily be extended from equipment with a single antenna
24、 to apply to equipment with multiple antennas, in order to evaluate performance under conditions more closely matching those of a particular application. -,-,- INTERNATIONAL STANDARD ISO/IEC 18046:2006(E) ISO/IEC 2006 All rights reserved 1 Information technology Automatic identification and data cap

35、ment must perform a sequence of communication processes within an “open” RF environment to transact the desired data with one or more tags in a potentially large tag population. This process begins with activation and segregation of the desired tags (small population) within the “open” larger popula
36、tion. This process concludes with the establishment of a communication link between the RFID interrogator and the tag allowing transaction (reading and/or writing) of application data. This initial process is described as “Identification”. Identification specifically refers to the process of tag seg
37、regation and isolation. This will result in a uniquely addressable means to communicate with a tag (tag ID). Application data has not been accessed. 5.2 Range An RFID system for item management requires the segregation and transaction of information remotely (i.e. non-line-of-sight). The physical se
38、paration between the interrogator and the tag is commonly referred to as range. Range specifically refers to the distance (minimum and maximum) between interrogator antenna and tag(s). For multiple tags, the range will be measured to the geometric centroid of the tag population. Tag density (tags pe
39、r unit volume) will be specified. -,-,- ISO/IEC 18046:2006(E) ISO/IEC 2006 All rights reserved 3 5.3 Rate An RFID system for item management may (and typically will) encounter multiple tags within a data acquisition session. As many applications require multiple tags to be processed within a fixed a
40、mount of time, a performance parameter dealing with “rate” is appropriate. Rate specifically refers to the quantity of tags per unit time. This includes impulse and steady state. Tag population will be both static and dynamic. Tag density (tags per unit volume) will be specified. 5.4 Read RFID tags
41、contain data. This data represents information about the item associated with the tag whether directly (item attendant) or indirectly (license plate). One of the significant performance characteristics of RFID relates to the ability of retrieving this “item data” in support of various business proce
42、ss requirements. This retrieval process is commonly referred to as “reading” and is separate from the previously described process of “identification”. Reading tag information assumes that a communication link has been established between the RFID interrogator and the tag. As such the collision arbi
43、tration (sometimes referred to as anti-collision) process is not involved. Reading of tag data is a “directed” data transaction with the activated and segregated tag. Reading specifically refers to the process of tag transaction to retrieve information from identified tag population. This process wi
44、ll include both single byte and multiple byte transactions. 5.5 Write As noted previously, RFID tags contain data. This data represents information about the item associated with the tag whether directly (item attendant) or indirectly (license plate). This information may at times be added and/or mo
45、dified through the RFID air interface. Should such a capability be available as part of an RFID system, a significant performance characteristic would be the ability of transferring this “item data” from the interrogator into the tag. This process is commonly referred to as “writing” and is the inve
46、rse of the previously described process of “reading”. Writing tag information assumes that a communication link has been established between the RFID interrogator and the tag. As such the collision arbitration (sometimes referred to as anti-collision) process is not involved. Writing of tag data is
47、a “directed” data transaction with the activated and segregated tag. Writing specifically refers to the process of tag transaction to write information into identified tag population. This process will include both single byte and multiple byte transactions. Write with verification will be available
48、. 5.6 Reliable RFID systems may require extensive dialog between the interrogator and the tag to fully complete the desired transaction with the tag population. It is not uncommon to have dialog errors during wireless communication. Various mechanisms (e.g. checksum, CRC, retransmission, etc.) may b
49、e used to ensure the integrity of the transactions. A reliable transaction specifically refers to the assurance that a tag and/or tag population will be identified accurately based on statistical likelihood and a defined confidence level. 5.7 Conditions RFID systems must perform the required transactions (i.e. identification, rea
