Foreword This Technical Report (TR) has been produc

15、ed by ETSI Technical Committee Electromagnetic compatibility and Radio spectrum Matters (ERM). The present document is part 1 of a multi-part deliverable covering RFID Plugtests to investigate the interoperability of tags manufactured by different vendors, as identified below: Part 1: “RFID Plugtest

16、s report“; Part 2: “Test plan and preliminary tests“. Introduction The present document describes an RFID Plugtest that was performed at the MGI centre in Neuss and at the VanDerLande premises in Veghel during the period 11th- 15th June 2008. The purpose of the tests was to investigate if there were

17、 any problems of interoperability when multiple tags manufactured by different vendors were simultaneously present in the same interrogation field. The question had been raised by some members of ERM_TG34 who had observed reduced reading performance when using different tag types on loads containing

18、 multiple items. This had led them to suspect that there may be an incompatibility between different designs of tag built with different ASICs. Since RFID is a global business that is frequently used in open systems, members of ERM_TG34 recognized that any interoperability between tags would be unac

19、ceptable. It was therefore considered necessary to carry out a series of tests at the earliest opportunity to determine whether there were any such problems existed. The tests simulated a number of real life scenarios in which tags manufactured by different vendors might be present simultaneously in

20、 the same interrogation zone. The tests are described in a test plan which was reviewed and approved by members of ERM_TG34 and are available at annex A. In addition, prior to the Plugtests, a practical investigation was made to measure certain characteristics of the ASICs. It was considered that th

21、ese measurements might assist in understanding the reasons for any incompatibility observed during the Plugtests. Three of the four test scenarios were preformed at the MGI centre in Neuss and comprised of the following: Reading tagged items of clothing using a hand-held reader. Reading of stacks of

22、 individually tagged DVDs using shelf antennas. Reading pallets containing multiple tagged items passing through a portal. In addition tests were carried out on a conveyor system at VanDerLande on which items with multiple tags passed reading stations. These tests simulated, for example, airline bag

23、gage fitted with RFID tags or tagged goods moving along a production line. Seven RFID manufacturers took part in the Plugtests. They all participated on the basis that the results of the tests on their equipment would remain confidential. The present document therefore only provides an overall summa

24、ry of the results recorded for each of the tests. In addition all of the participants in the tests had completed the ETSI Non-disclosure Agreement.

35、ssible problems of interoperability between tags manufactured by different vendors. To determine if this was the case, a series of tests, simulating real life scenarios, were defined. The tests were carried out the Metro Innovation Center in Neuss and at VanDerLande in Veghel. Seven manufacturers of

36、 interrogators and two tag vendors participated in the tests. A total of eleven different tag types were tested, which included some RFID baggage labels provided by Air France. Prior to the Plugtests an investigation had been carried out under laboratory conditions to determine if there were any obv

37、ious differences in the behaviour of ASICs (in the tags) that were manufactured by different foundries. Measurements made during this investigation showed that there was a noticeable difference in the behaviour of the session flags, which appeared to be dependent on the foundry that had produced the

38、 ASIC. However it was not clear if the difference would give rise to a reduction in reading performance in normal operation where mixed populations of tags were present. The results from the Plugtests showed that there was no apparent difference in reading performance, due to any interoperability is

39、sues associated with the ASICs, between populations of tags from a single manufacturer and with mixed populations of tags. It was observed that there was a noticeable difference in the sensitivity of different tag types, which directly affects their reading range. In applications where mixed types o

40、f tag might be used, it will be important to specify all tag types correctly to ensure that they are compatible with the system requirements. Two distinctly different types of tag are available for item level tagging. One type is designed to be operated by a conventional radio wave. The other type i

41、s energized by a field that is predominantly magnetic. The antennas designed to read these two tag types are different. In an environment where both tag types are present, care will be necessary during system design to ensure that acceptable reading performance is achieved. Tests on a conveyor demon

42、strated that it is possible to operate satisfactorily in situations where the interval between successive reads of the same tag by different interrogators is less than 2 s. Additional tests showed that using the select command it is possible to read only the “wanted tags“ from a large population of

43、mixed tags. During the Plugtests it became apparent that not all manufacturers had a proper understanding of the features in the ASICs. This applied in particular to the use of the “select“ command and the session flags. The correct use of these features is essential if optimum performance is to be

44、achieved. Guidance on the behaviour of these functions, and how best they should be configured, is provided in an annex to the present document. The outcome from the Plugtests was satisfactory and, based on the samples presented for the tests, showed that there was no incompatibility between differe

45、nt tag and ASIC types. ETSI ETSI TR 102 644-1 V1.1.1 (2008-12)85 General The names of the seven manufacturers of interrogators who participated in the tests were Hoeft & Wessel, Impinj, Kathrein, Nordic ID, Panmobil, Sirit and ThingMagic. In addition 10 different tag types were provided by three lab

46、el manufacturers using ASICS from two different foundries. Further details of the tags are included in annex A. Also a number of airline RFID baggage labels were supplied by Air France. For three of the test scenarios a pre-programmed tag was attached to each of the objects under test. The objects w

47、ere divided into groups with tags assigned by tag type to each group. In addition there was an additional group which comprised items that included tags manufactured by different tag vendors. This made it possible to compare the performance of tags by type against the performance of a mixed populati

48、on of tags. For practical reasons, in the case of the conveyor system, each item had three different tag types attached to it, although it was possible at any time to disable any two of the three tags. The ID number and type of all of the tags were pre-loaded into the IBM server prior to the Plugtes

49、ts. In addition the server contained an application tool that enabled easy manipulation of the recorded results to provide useful information. Each participant recorded each of their results on log files, which were subsequently transferred to the server following each test sequence. The total number of individual records that were logged during the Plugtests exceeded half a million. Prior to each test the participant provided the test supervisor with details of the configuration of his interrogator. The configuration selected was the one considered by the part
