Introduction Currently the Brazilian regulations concerning RFID are based on the FHSS mode of operation, as commonly used in the Americas, rather than the four channel plan that has been adopted in Europe. However with the increasing number of RFID technologies and appli

17、cations available at UHF, the Brazilian RFID community has recently expressed a strong interest in participating in an ETSI Plugtests event. They believed that this would provide them with a better understanding of the role of ETSI within Europe and of the standardization activities that had taken p

18、lace on RFID at UHF within the ETSI Technical Body TC ERM TG34. CPqD is aware of the increasing number of RFID technologies and applications presently available at UHF. Furthermore in Brazil GSM operates in the frequency bands 907,5 - 915 MHz, which is adjacent to the band occupied by RFID. These fa

19、ctors have led CPqD to identify the need to perform an interoperability test in co-operation with an independent international standardization body. Subsequently arrangements were made to perform Plugtests with the European Telecommunications Standards Institute (ETSI). The present document describe

20、s a test plan to evaluate the comparative performance of the FHSS mode of operation as commonly used in the Americas and the four channel plan that has been adopted in Europe. ETSI ETSI TS 103 302 V1.1.1 (2015-04)5 1 Scope The present document describes the test scenarios performed at the RFID Inter

21、operability event in Brazil. The interoperability event, also called Plugtests event is being organized by ETSI, CPqD and FP7 Probe-IT Project. The event took place from 20 - 24 May 2013 at the CPqD Head Quarters, in Campinas, Brazil. The primary purpose of the tests was to compare the performance b

22、etween interrogators when configured in the FHSS mode and interrogators configured to operate in accordance with the 4 channel plan, defined by ETSI and adopted in Europe. In addition further tests were carried out to assess the reading performance of tags when attached to “unfriendly“ items and the

23、 effect of tag orientation. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

Following completion of Parts 1 and 2 representatives from CPqD shall supervise Part 3 and Part 4 assisted by the representatives from ETSI. On completion of the Pl

35、ugtest CPqD and ETSI jointly prepare a Technical Report (ETSI TR 103 271 i.1), which includes an analysis of the test results. 4.2 Equipment ETSI provided the following equipment for the Plugtests: 1) 3 x demonstrators capable of operating in the band 915 - 921 MHz and incorporating DAA. Additionall

36、y they had the ability to operate under the four channel plan. Each interrogator was capable of driving at least two antennas with an output of 4 W eirp. 2) All interrogators were fitted with SMA female connectors. 3) The software application for operating the demonstrators and controlling operation

37、 of the DAA. This software included the ability to log the successful reading of tags together with recording the total time taken to complete the operation. CPqD provided: 1) 3 x interrogators using FHSS mode and modified for operation at Brazilian frequencies. 2) 4 x circularly polarized antennas
