  1. Radio Microphone Task Force Report Presenter: Dr. Gabrielle Owen, ETSI TC ERM Chairman

  2. Highlight of Current Activities • Within Europe the implementation of the MFCN 790-862MHz spectrum and White Space Device proposals for the 470-790 MHz band has resulted in a number of CEPT groups investigating both spectrum requirements and testing programs for radio microphone compatibility with these services. • This is the first time that such extensive work has been carried out and we have placed a number of documents in the task Force Docbox along with the published output of the Cognitive PMSE group : • This year the ETSI STF 386 and the German C-PMSE group have the same membership and their update follows this slide

  4. Content • Overview on STF386 • Experts • Status at the end of phase 2 • German National Research Project C-PMSE funded by BMWI • Objectives and status of work with phase 3 • C-PMSE Demo Workshop in Berlin

  5. 1 - Overview • Overview • ETSI Specialist Task Force • Expert team working for a limited period of time • Focus on a specific technical question • Funding by ETSI • Scope • Set by ToR (Terms of reference): “Methods, parameters and test procedures for cognitive interference mitigation techniques for use by PMSE devices (Programme Making and Special Events)” • Purpose: Achieve co-existence of high audio quality PMSE devices using often a 100% transmitter duty cycle emission profile with victim radio services such as Services in L-Band or Broadcast Services and future Land Mobile Services and applications in the UHF frequency range that is currently under investigation under the “Digital Dividend” discussions in EC, ECC and ETSI fora.

  6. 2 - Experts • Industry • Shure Europe: Wolfgang Bilz • Shure US: Edgar Reihl • Sennheiser: Dr.Axel Schmidt • SME • WiseSense: Dr. Andreas Wilzeck • Research Institute • IRT: Clemens Kunert • Academia • University of Hannover: Dr. Maria-Dolores Perez-Guario • Ruhr University Bochum: Dr. Sven Dortmund • FAU, University of Erlangen Nürnberg:Prof. Dr. Georg FischerJohannes Brendel • Association • APWPT: Matthias Fehr

  7. 3 - Status at the end of phase 2 • Status • Two Reports have been generated • Phase 1 deliverable • Technical Report ETSI TR 102 799 • “Operation methods and principles for spectrum access systems and quality control of used spectrum for PMSE technologies utilising cognitive interference mitigation techniques” • Describes main architectural concepts and procedures • Phase 2 deliverable • Technical Report ETSI TR 102 800 • “Protocols for spectrum access and sound quality control systems using cognitive interference mitigation techniques” • Describes recommended spectrum access technique  

  8. 4 - German National Research Project C-PMSE • Project Overview • Duration 26 month, April 2011 - May 2013. • 9 partners from industry, research institutes and universities. • Budget about 7.5 million EUR. • funded by the German Federal Ministry of Economics and Technology (BMWi) • Project keeper German Aerospace Center (DLR) in Cologne • Goal: The project goal is the design, development, test and research on a cognitive PMSE system which provides cooperative coexistence with other C-PMSE systems, white space devices, broadcasting and mobile radio • Basic requirements are automation of the frequency utilization within the assigned frequency spectrum, securing a coordinated coexistence of different user in the same frequency range and efficient frequency utilization.

  9. Project Objectives • R&D on the cognitive system and procedures for PMSE by development of system components, like antennas, scan receiver, scan controller, cognitive engine, data base and so on, measurement- and test procedures as well as channel-, interference- and coexisting models as reference for the standardization and regulation activities. • Setting up a field trial platform for cognitive PMSE applications at the fair grounds of Messe Berlin, technical and economical proof of concept of the cognitive methods for PMSE and realizing an open and modular R&D platform for future research. • Supporting frequency regulation and standardization by setting up a forum to discuss and prioritize necessary actions concerning cognitive PMSE on national, European and worldwide level as well as active collaboration with ITU, ETSI, CEPT and Bundesnetzagentur by using the project results and the preparatory work of the Special Task Force ETSI STF 386.

  10. C-PMSE architecture Information acquisition Cognitive PMSE

  11. Synergy Characteristics of C-PMSE • Cognitive behaviour not totally new, already cognitive manual behaviour by today (handheld scanning receiver, audio engineers listening) • Interference identification so far done manually already today, now it is automatic and thus more dynamic • Link to Geolocation database • Local spectrum sensing grid • Automatic link quality supervision, also for analogue FM ! (C/I equivalent, not signal strength), digital PMSE is not a must for C-PMSE • Automatic frequency changes and transmit power control Synergy between BMWI C-PMSE Project and STF386 • Partners in the German Research Project and in STF386 partially are identical • Through the research on implementation of a cognitive PMSE system, valuable input is given to Standards • Results from field trial in research project will enter ETSI Technical Report by STF386 • Envisioned kick-off of a new work item in ETSI is backed by solid practical experience

  12. Objectives and status of work with phase 3 Deliverable • Drafting of Deliverable: TR 102 801 - ETSI Technical Report of the different RF compliance tests for the selected spectrum access mechanism, as defined in TR 102 800 – ETSI Technical Specification on the recommended spectrum access technique (phase 2) Objectives • Validation of TS 102 800. • STF will specify input test scenarios for the technology demonstrator implementing TS 102 800 on protocols for spectrum access and sound quality control systems for PMSE applications using cognitive interference mitigation techniques. • C-PMSE Project will provide essential input based on the carried out field measurement at their test site and practical assistance to STF386. • STF will take advantage of the synergy with the research project C-PMSE to validate and upgrade the TS developed in the previous phases. This is a unique opportunity to progress standardization in parallel with research.
