RFID Plugtests

This Plugtests event was organized by ETSI in co-operation with the FP7 Probe-IT project and was hosted from 20-24 May 2013 at the CPqD Head Quarters, in Campinas, Brazil. 

RFID is a key component in the Internet of Things (IoT). This event combined interoperability testing, technology evaluation and coexistence aspects of RFID tags and readers. The tests focused on three main areas:

  1. A comparison between the FHSS method of operation used in the Americas and the four channel plan adopted by Europe.
  2. ETSI demonstration of the operation of mitigation techniques which have been designed to enable RFID to share the same frequency band.
  3. Analysis of interference between RFID and GSM.
  4. An assessment of a typical Brazilian application involving the movement of tagged goods on a conveyor.

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 applications 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 place on RFID at UHF within the ETSI Technical Body TC ERM TG34.

In Brazil the frequency band used in RFID technology, (~ 902-907.5 MHz and 915-928 MHz), is very close to the band used by cellular mobile communication technologies, particularly, the GSM 900 reinforcing the need to carry out an interference evaluation test between these systems.
The results of the study will greatly assist in future technical developments in Brazil and contribute towards improvements in their national standards. In addition the Plugtests should lead to greater technological cooperation between the two regions.

This event combined interoperability testing, technology evaluation and coexistence aspects.  Analysis of the results showed that the ability of both the FHSS and 4 channel modes to identify a sample of 50 tags correctly was very similar. Also the results for the tests on the mitigation techniques showed that there was very little difference in the performance between them. The one major difference between the two methods was the data rates that were achievable
