Foreword This Technical Report (TR) has been produced by ETSI

19、Technical Committee Electromagnetic compatibility and Radio spectrum Matters (ERM). The present document is part 2 of a multipart deliverable covering 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. Part 1

20、: “RFID Plugtests report“; Part 2: “Test plan and preliminary tests“. Introduction Different applications, like conveyor belts or dock door portals, are characterized by different properties such as field characteristics, tag population, speed and tag/reader density. These properties impose differen

21、t requirements such as read or write sensitivity and resistance to mutual coupling. When exposing tags of various types from different vendors to application specific conditions, some tags might influence the operability of others, thereby being mutually incompatible. The goal of tag interoperabilit

22、y tests is to investigate issues of potential incompatibility that arise due to the use of tags of various types from different vendors in application specific conditions. The result is the test report made publicly available via the ETSI web-page. Prior to the RFID Plugtests, preliminary tests were

23、 conducted using a well documented, dedicated test reader with one antenna port and special measurement equipment for extended evaluation options (referred to as the control reader). In order to gain the best understanding of possible anomalies these preliminary tests were conducted using two differ

24、ent set-ups. The ASIC specific test set-up focused on the inventory of multiple tags hard wired to the control reader, (i.e. eliminating the influences of the RF field). The tag specific test set-up focused on the inventory of multiple tags under application specific conditions (using an antenna to

25、generate a RF field instead of hard wiring the tags to the control reader). In the second step the ETSI RFID Plugtests were executed in application scenarios using commercially available equipment. As the results of the preliminary tests merely provide a basis for understanding potential issues, onl

26、y the results of the ETSI RFID Plugtests are included in Part 1 of TR 102 644 i.6. ETSI ETSI TR 102 644-2 V1.1.1 (2009-03)61 Scope The present document defines a test plan for tag interoperability tests. The main objective of such tests is to confirm that mixed populations of tags (tags of different

27、 types and/or from different vendors) can be identified correctly. The tests are defined in a two-step approach. The present document identifies the main factors influencing tag interoperability including application scenarios, protocol parameters and individual tag characteristics. Each of these as

28、pects is addressed in detail with the aim of providing a test plan and evaluation matrices for tag interoperability tests. Protocol specific issues in the present document are focused on the EPCglobal Class 1 Generation 2 (C1G2) air interface specification i.2 and the air interface specification ISO

29、/IEC 18000-6 Type C i.3. The present document served as basis for carrying out ETSI Plugtests (RFID Interoperability Event) in June 2008. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

39、ability 4.1 Preface The main factors influencing tag interoperability are the application scenario, protocol parameters, and individual tag characteristics. Each of these factors is addressed in detail in the following clauses. However due to the large number of variables associated with application

40、 scenarios and protocol parameters, it is only possible to cover the main factors influencing tag behaviour. Since there could be issues in assigning interrogator related characteristics either to the application scenario or to the protocol parameters, the following convention is adopted: software d

41、efinable characteristics are assigned to the protocol parameters while all others are assigned to the application scenario. 4.2 Application Scenario The application scenario describes the set-up in which an RFID interrogator and tags are used. The main characteristics of an application scenario incl

42、ude: Environment: - All aspects that have a certain influence on an application but are not part of the application itself (like surrounding material, noise sources of any kind e.g. mobile phones). Reader antenna arrangement: - Position and orientation of the reader antennas in a set-up. - Number of

43、 reader antennas. - Type of reader antennas. Tag arrangement: - Position and orientation of the tags in a set-up. - Number of tags. ETSI ETSI TR 102 644-2 V1.1.1 (2009-03)8- Type of tags (different vendors/models). Relative movement between reader antennas and tags: - Speed. - Path: square4 E.g. pal

44、let moving through portal (tags moving). square4 E.g. handheld reader (reader antenna moving). Pallet / Case / Item characteristics: - Materials. - Arrangement. 4.3 Protocol Parameters The protocol parameters describe the protocol settings, as well as other software options associated with a particu

45、lar application set-up. The main protocol parameters are (C1G2 specific where applicable): Link rates: - Forward link. - Return link. Modulation/Encoding: - Modulation type (forward link). - Modulation depth (forward link). - Duty cycle (forward link). - Encoding (return link). CW: - Power. - Freque

Protocol flow: - Command sequence. - Collision-arbitration concept (Q protocol). - Function: square4 Selection/inventory only. square4 Access - write. Session usage: - Session flag. - Selected flag.

Reader antenna switching: - Sequence. - Timing. - Interrelation with protocol concepts (e.g. inventory round). 4.4 Individual Tag Characteristics The individual tag characteristics describe attributes that, due to variation

48、s between different tags, may influence tag interoperability. Some of these attributes are defined for the RFID Plugtests and assume tags operating under ISO/IEC 18000-6 i.3. Read range: - The sensitivity of a tag typically expressed as forward link range for a given transmit level. Orientation tole

49、rance: - The sensitivity of a tag in terms of its read range if it is rotated away from its preferred orientation. Frequency tolerance: - The sensitivity of a tag in terms of its read range at various carrier frequencies from 860 MHz to 960 MHz. - Tags with high frequency tolerance typically show less variation in sensitivity if attached to different materials. Interference tolerance: - Describes the degradation in read range of tags from interference generated by other nearby interrogators (e.g. dense interrogator
