5. Spectrum Management Cycle in the past???? Regional ITU Workshop, Amman, 5 - 7 December 20115

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 7Regional 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 8Regional 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 20119

10. Spectrum Monitoring goals - 4  Enforcement: interference resolution (reactive); interference resolution (reactive); campaigns (proactive) on illegal usage; campaigns (proactive) on illegal usage; check parameters of emissions. check parameters of emissions. 10Regional 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. 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 201111

12. Planning a new monitoring network  Main considerations;  Main questions to be answered;  How about the available budget? Regional ITU Workshop, Amman, 5 - 7 December 201112

13. Main considerations  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 201113

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 201114

15. Main questions - 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 201115

16. Main questions - 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 201116

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. Requirements for a monitoring system  What antenna system is needed?  Quality of the equipment;  What type of tasks are to be carried out?  What performance of the results is needed?  Communication between the various station? Regional ITU Workshop, Amman, 5 - 7 December 201118

33. 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 2nd carrier installed for capacity reasons New UMTS site on air closer to monitoring station Spectrum available for awarding Telfort licence returned to RCA because of non- compliance 33

34. Theory versus practical Regional ITU Workshop, Amman, 5 - 7 December 201134

35. Some conclusions  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 questions need to be responded; Regional ITU Workshop, Amman, 5 - 7 December 201135
