Functional elements in Spectrum Management Regional ITU Workshop, Amman, December 20113

Spectrum Management Cycle Regional ITU Workshop, Amman, December 20114

Spectrum Management Cycle in the past???? Regional ITU Workshop, Amman, December 20115

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

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, December 2011

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, December 2011

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, December 20119

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, December 2011

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, December

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

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, December

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, December

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, December

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, December

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

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, December

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

Theory versus practical Regional ITU Workshop, Amman, December

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, December
