  6. 6. Collective Letter 09_2749 Page 6 of 14 ANNEX C ToR STF UF (ERM / TG34) Version: 0.5 - Date: 2 October 2009 Author: Thomas J Weber, 1st September 2009 Last updated by: John Falck 2-Oct-09 page 6 of 14 Terms of Reference for Specialist Task Force STF UF (ERM / TG34) “Methods, parameters and test procedures for cognitive interference mitigation for use by UHF RFID using Detect-And-Avoid (DAA) or other similar techniques” Document status Status of ToR Approved by ERM TG34. Approved by Board#75, pending confirmation ERM#39 Work Items DTR/ERM-TG34-009, DTR/ERM-TG34-010 for approval at ERM#39 (16-20 Nov 2009) 1Reasons for proposing the Specialist Task Force (STF) TC ERM is, through its TG34 (UHF RFID) task group, developing standards for UHF RFID applications. In the summer of 2008 ETSI-ERM sent the ETSI System Reference Document ETSI TR 102 649-2 to CEPT/ECC requesting additional spectrum for UHF RFID. RFID would operate in the band 915 MHz to 921 MHz in four high power channels while the remainder of the frequency band would be used for the low power responses from the tags. Full details are available in ETSI TR 102 649-2. In parallel, ETSI TC RT on the subject of Extended GSM-R independently sent an ETSI System Reference Document to ECC requesting an extension of their existing band to include the frequencies 918 – 921 MHz (E-GSM-R, paired with 873-876 MHz). CEPT/ECC has looked favourably on this request and it was decided to revise ECC Decisions (04)06 and (02)05 to include E-GSM-R. Germany has already included E-GSM-R in their frequency utilization plan and has also given a license to a railway operator for E-GSM-R. It may be expected that other countries will also follow. According to the implementation plans for GSM-R in Europe, E-GSM-R will be used on high speed railway tracks as well as locations with high railway usage, e.g. shunting areas, urban areas. In other areas, or in some countries, E-GSM-R may not be used. Testing, involving an administration, railway operator and members from the RFID community in ERM TG34, was performed in the summer of 2009 to understand under what conditions it might be feasible for RFID to co-exist with E-GSM-R (i.e. E-GSM-R BS transmit band) in the band 918 MHz to 921 MHz. RFID would operate as a secondary application and shall not cause harmful interference in the PMR/PAMR band 915-921 MHz. In theory it may be restricted to operate within defined areas (e.g. indoor use) and may also use intelligent detect-and-avoid (DAA) mechanisms. For example if the system is able to detect E-GSM-R transmissions above a certain threshold on a particular channel, it could instruct the interrogator to select an alternative frequency of operation. Another way to improve compatibility would be to minimize the use of the 2 upper proposed RFID channels at 918.6 MHz and 919.8 MHz. In addition, interfering intermodulation products must be avoided.
  7. 7. Collective Letter 09_2749 Page 7 of 14 The tests have shown that it is feasible for RFID and E-GSM-R to co-exist. To ensure that RFID does not interfere with E-GSM-R, the interrogator must not transmit within a minimum frequency offset of transmissions from nearby base stations. This could be achieved by the use of intelligent detect-and- avoid (DAA) or other equivalent cognitive techniques. If the system is able to detect E-GSM-R transmissions above a certain threshold on a particular channel, it could instruct the interrogator to select an alternative frequency of operation. The RFID interrogator could perform an E-GSM-R channel scan and measure the level of signals from the base station to determine whether a spare high power channel is available. The threshold set in the interrogator will determine the distance from the base station at which it may transmit on the same channel. Another way to improve compatibility is to minimize the use of the 2 upper proposed UHF RFID channels above 918 MHz The ETSI standardization groups dealing with E- GSM-R (TC RT TG EGSMR and ERM TG34) should work together on a detailed concept for co-existence. Their work should be supported by compatibility studies in ECC WGSE. It is also planned to update ETSI TR 102 649-2 in order to incorporate the test results and DAA feasibility considerations. The present UHF RFID band (865 - 868 MHz) is becoming increasingly congested. The growing demand for UHF RFID services and the demand for extra bandwidth are putting even more strain on the over-stretched UHF spectrum. Currently UHF RFID in Europe operates in only 4 x 200 kHz RFID reader channels, which is considerably less than the available spectrum for UHF RFID in other regions outside Europe. Additional spectrum potentially could be made available for RFID but would require satisfactory sharing of the frequency band with E-GSM-R. This would necessitate the use of suitable mitigation techniques such as DAA. The proposed STF would investigate this concept, define a suitable DAA (or equivalent) method and apply it to a technology demonstrator, to be developed by the industrial members of ERM TG34. The development of exact parameters, operation principles and the test definition for co-existence with EGSM-R is seen as a prerequisite for achieving this target. Please note that although the technology demonstrator will concentrate on one particular application, i.e. protection of e-GSM-R, the technique may ultimately be transferable to other sharing situations. 1.1Overview of the proposal 1.1.1Purpose of the work The purpose of the work is to achieve co-existence of UHF RFID devices with the victim radio service E-GSM-R. All procedures, techniques and solutions developed by this STF should be ultimately transferrable to ETSI UHF RFID specifications and standards. It should also be stressed, that whilst the demonstrator might be designed for a specific purpose, the techniques should be applicable to a wide range of frequencies. For the complete standardisation of the mechanisms, suitable technical parameters and test procedures are needed. These include flexible mechanisms such as detection thresholds and possibly the recognition of victim service patterns. There are currently several sub-groups in CEPT/ECC dealing with regulatory and co-existence aspects of UHF RFID. These will all influence the technical requirements, content and standardization requirements within ETSI (e.g. ECC/WGSE, SE24, ECC/WGFM/SRDMG, etc.). It will be the
  8. 8. Collective Letter 09_2749 Page 8 of 14 responsibility of ERM TG34 to mirror these regulatory requirements into technical specifications and test procedures. 1.1.2Relation with the ETSI strategic objectives Co-existence with other radio services and applications is one of the strategic topics in all RF conformance standards developed by ETSI. Since it is related to article 3.2 of the R&TTE Directive, it is also strategically important for ETSI as an European Standards Organization. The results of this STF will ease the development of a revised EN 302 208 or even stimulate the creation of a new Harmonized European Standard under the EC standardization Mandate M/289. 1.1.3Market impact, benefits to be gained The expectation is that the European market for UHF RFID systems will grow larger and faster if devices operate within the same band used by the major trading nations in other parts of the world (i.e. 902 MHz to 928 MHz). 1.1.4Interest of ETSI Members and other stakeholders ERM TG34 will progress their work on the Harmonized Standard EN 302 208 based on the results of the proposed STF work. The inclusion of DAA (or equivalent) will greatly improve usage of the Harmonized European Standard. 1.1.5Relation with other activities within ETSI and/or related organizations For completion of the standardisation process of the DAA (or equivalent) mechanisms, the following contributions are required: • an initial “brainstorming” meeting where all of the related issues should be considered • suitable technical parameters for DAA (or equivalent) mechanisms • a DAA (or equivalent) test bed for performance validation • the validation of DAA (or equivalent) test procedures in a certified test laboratory environment In order to complete its task, the STF will establish technical collaboration with existing organisations (see below). It will conduct technical studies and research on DAA and other cognitive mitigation mechanisms, and spectrum access methods as well as suitable support systems. The STF will include in their results a proposal for the DAA (or equivalent) test specifications that could be incorporated in the base Harmonized European Standard EN 302 208 for UHF RFID communications devices. Liaisons will be established with: • CEPT/ECC for a for the provision of appropriate regulatory requirements • ETSI TC RT TG E-GSM-R For the completion of the standardisation process of cognitive interference mitigation mechanisms, the following contributions are required: • suitable technical parameters for DAA (or equivalent) mechanism regarding E-GSM-R, • a DAA (or equivalent) test bed for performance validation, • the validation of DAA (or equivalent) test procedures in a certified test laboratory environment • suitable technical parameters for the elimination of inter-modulation products. The STF liaisons are planned to be coordinated in a timely manner via a proposed steering committee, i.e. the STF experts will not liaise directly but look for approval from the steering committee members.
  9. 9. Collective Letter 09_2749 Page 9 of 14 1.1.6Priority within the TB High 1.1.7Motivation why the work cannot be performed within the TB Experience with the development of other interference mitigation techniques has shown that involvement of experts on radio frequency conformance testing with knowledge of the concerned operational protocols is needed. The generation of this kind of specification requires significant concentrated effort, and it cannot be expected that this effort can be provided only on a voluntary basis. Hence the involvement of testing, spectrum and regulatory experts is needed in order to assure the timely completion of test specifications of a high quality. These testing experts are not available at the TC ERM level and need to be recruited on a funded basis. 1.1.8Support from ETSI Members The following ETSI Members support the creation of an STF to produce the deliverables listed in §3.14: • LPRA • BMWI • Motorola • Bosch • DB AG • FEIG • Siemens • other members to confirm their support, including the Swiss and Austrian administrations Member companies are prepared to contribute voluntarily: • 10 working days of voluntary contribution towards drafting of STF deliverables • 70 working days of voluntary resource for performing review of the deliverables (drafts for review or approval in the TB). This represents an estimated equivalent of 42 000 Euro. The supporting ETSI members of this STF will voluntarily contribute the laboratory facilities, measurement equipment and equipment under test necessary to perform the validation (testing). This represents an estimated equivalent total voluntary contribution of 48 000 Euro. 1.2Organization of the work 1.2.1Identification of tasks, phases, priorities The documents to be produced by the STF are: a) Technical Specifications for DAA (or equivalent) mitigation techniques for UHF RFID implemented technologies. b) Technical Report on the different RF compliance tests for the DAA (or equivalent) mechanism of UHF RFID implemented technologies.
  10. 10. Collective Letter 09_2749 Page 10 of 14 The work will be done in two phases. • Phase 1: ETSI Technical Specification to be submitted to the concerned ECC bodies by the middle of 2010. • Phase 2: ETSI Technical Report containing the information on validation of the RF tests for the DAA (and equivalent) mechanism with measurements by end of 2010. ERM is expected to adopt new work items in November 2009 for the two above mentioned documents. 1.2.2Outcome of the STF The STF will produce a TS and a TR. The production of the technology demonstrator will be developed by the industrial members of ERM TG34 and shall be available in time for the planned validation on a test-bed. This development will be performed outside of the ETSI STF. 1.2.3Risk involved: The risk involved is low based on existing experience with similar functional mechanisms and the fact that ECC will set out a firm criteria for success. In addition, it is expected that TC RT TG E-GSM-R will collaborate to ensure the protection of E-GSM-R. 2Consequences if not agreed: The production of DAA (or equivalent) test specifications as described in the present document is key to the testing and certification activities. It should ensure the co-existence of UHF RFID radio devices having DAA (or equivalent) with E-GSM-R and possibly, other radio services and applications. A poor initial specification can be detrimental to the further successful market development of UHF RFID in Europe. Delaying the availability of good test specifications may adversely affect the arrival of products in the market place and their level of conformance. The most promising way to ensure access to the proposed new spectrum is to utilise cognitive spectrum access methods. This would allow use of hitherto un-available spectrum and facilitate spectrum sharing. ERM TG34 itself does not have the resources to investigate this issue. If the STF proposal is not agreed, it would not be possible to explore cognitive spectrum access techniques and it would not be possible to satisfy the growing market demand for UHF RFID services. 3Detailed description: 3.1Subject title: Methods, parameters and test procedures for cognitive interference mitigation techniques such as Detect-And-Avoid (DAA) for use by UHF RFID 3.2Reference Technical Body: TC ERM will be responsible for the approval and publication of all the deliverables of this STF 3.3Other interested TBs: See 1.1.5
