  1. Design and implementation of monitoring systems Jan Verduijn Chairman ITU-R WP1C on Spectrum Monitoring ITU-D expert

  2. Outline • Role and tasks of a monitoring service; • How to design a monitoring network; • Requirementsfor a monitoring network; • Integration in a spectrum management system; • Someexamples • Conclusions Regional ITU Workshop, Amman, 5 - 7 December 2011

  3. Functional elements in Spectrum Management Regional ITU Workshop, Amman, 5 - 7 December 2011

  4. Spectrum Management Cycle Regional ITU Workshop, Amman, 5 - 7 December 2011

  5. Spectrum Management Cycle in the past???? Regional ITU Workshop, Amman, 5 - 7 December 2011

  6. Spectrum Management Process Key elements in Spectrum Management: • Frequency Management (PLANS) • Licensing (PERMITS) • Enforcement (VERIFIES) Role of Monitoring : To support these key-elements in order to realise a usable and interference free spectrum

  7. Spectrum Monitoring goals - 1 To support spectrum management strategy, dependent on national regulatory policy: • Spectrum engineering/planning: for spectrum users through ‘first come - first served’, auctions, beauty contests and re-farming of frequency assignments Regional ITU Workshop, Amman, 5 - 7 December 2011

  8. Spectrum Monitoring goals - 2 • Frequency management: actual usage evidence, frequency band audits, frequency band occupancy/usage • Frequency co-ordination and notification: national and international co-ordination rules, models, measurements Regional ITU Workshop, Amman, 5 - 7 December 2011

  9. Spectrum Monitoring goals - 3 • Licensing/authorisation: licence compliance inspection (proactive or reactive), frequency channel occupancy statistics • Network roll-out/Quality of Service (QoS):licence compliance and market information for consumers (e.g. mobile phone / broadcast) Regional ITU Workshop, Amman, 5 - 7 December 2011

  10. Spectrum Monitoring goals - 4 • Enforcement: • interference resolution (reactive); • campaigns (proactive) on illegal usage; • check parameters of emissions. Regional ITU Workshop, Amman, 5 - 7 December 2011

  11. Role of Monitoring in the overall Spectrum Management process Monitoring can be defined as a process of observing the radio frequency spectrum and report on the use of it. Regional ITU Workshop, Amman, 5 - 7 December 2011

  12. Planning a new monitoring network • Mainconsiderations; • Mainquestionstobeanswered; • How about the available budget? Regional ITU Workshop, Amman, 5 - 7 December 2011

  13. Mainconsiderations • Coverage areas of monitoring based on responsibilities of the regulator; • Coverage areas of monitoring based on the needs of other functional elements of the spectrum management process; Regional ITU Workshop, Amman, 5 - 7 December 2011

  14. Design of a monitoring network - 2 • Coverage areas of monitoring based on future planned use of radio communication; • Coverage areas of monitoring based on monitoring needs; • Other elements for consideration: • Coverage areas of monitoring based on practical implementation; • Spread of the population; • Size of the country Regional ITU Workshop, Amman, 5 - 7 December 2011

  15. Mainquestions - 1 • Based on the size of the country; • Where to locate manned monitoring stations; • Where to locate automated remote fixed monitoring stations; • What are the frequency bands to be covered and how; • What type of equipment is needed; Regional ITU Workshop, Amman, 5 - 7 December 2011

  16. Mainquestions - 2 • How many mobile monitoring vehicles are needed; • How many transportable stations are needed; • Is space monitoring needed? • Available budget; • Monitoring principles Regional ITU Workshop, Amman, 5 - 7 December 2011

  17. Principle of monitoring policy ‘What can be done, using the equipment and facilities of the (Remote) Fixed Monitoring Stations, should not be done by Mobile Monitoring Stations.’ In remote areas more need for direction finding equipment

  18. Requirementsfor a monitoring system • Whatantenna system is needed? • Quality of the equipment; • What type of tasks are tobecarried out? • What performance of the results is needed? • Communication between the various station? Regional ITU Workshop, Amman, 5 - 7 December 2011

  19. Example frequency band scan (spectrogram) Regional ITU Workshop, Amman, 5 - 7 December 2011

  20. Example frequency channel ocupancy Regional ITU Workshop, Amman, 5 - 7 December 2011

  21. Spectrum mask measurement Regional ITU Workshop, Amman, 5 - 7 December 2011 21

  22. T-DAB 227 MHz Regional ITU Workshop, Amman, 5 - 7 December 2011

  23. PMR 460 MHz Regional ITU Workshop, Amman, 5 - 7 December 2011

  24. GPS jammer, 1,5 GHz Regional ITU Workshop, Amman, 5 - 7 December 2011

  25. Digital networkfor the police 380 – 390 MHz Regional ITU Workshop, Amman, 5 - 7 December 2011

  26. Wimax 3.4 – 3.6 GHz20102011 Regional ITU Workshop, Amman, 5 - 7 December 2011

  27. Regional ITU Workshop, Amman, 5 - 7 December 2011

  28. Regional ITU Workshop, Amman, 5 - 7 December 2011

  29. WIFI, license exempt 5,470 tot 5,725 GHz 5,150 tot 5,350 GHz 2,400 tot 2,480 GHz Regional ITU Workshop, Amman, 5 - 7 December 2011

  30. Effect of a hectic incident Regional ITU Workshop, Amman, 5 - 7 December 2011

  31. Regional ITU Workshop, Amman, 5 - 7 December 2011

  32. Regional ITU Workshop, Amman, 5 - 7 December 2011

  33. Spectrum available for awarding Telfort licence returned to RCA because of non-compliance Orange bought by T-Mobile. Orange network switch-off for increased efficiency RCA demands 2 carriers from T-Mobile to meet T-Mobile and former Orange licence conditions New UMTS site on air closer to monitoring station 2nd carrier installed for capacity reasons

  34. Theory versus practical Regional ITU Workshop, Amman, 5 - 7 December 2011

  35. Someconclusions • Monitoring is important to assist in the spectrum management process: • For the Regulator itself; • For the users • For the design and quality of a monitoring network a number of important considerations and questionsneedtoberesponded; Regional ITU Workshop, Amman, 5 - 7 December 2011
