Design and implementation of monitoring systems Jan Verduijn Chairman ITU-R WP1C on Spectrum Monitoring ITU-D expert
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
Functional elements in Spectrum Management Regional ITU Workshop, Amman, 5 - 7 December 2011
Spectrum Management Cycle Regional ITU Workshop, Amman, 5 - 7 December 2011
Spectrum Management Cycle in the past???? Regional ITU Workshop, Amman, 5 - 7 December 2011
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 Regional ITU Workshop, Amman, 5 - 7 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 Regional ITU Workshop, Amman, 5 - 7 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, 5 - 7 December 2011
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
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
Planning a new monitoring network • Mainconsiderations; • Mainquestionstobeanswered; • How about the available budget? Regional ITU Workshop, Amman, 5 - 7 December 2011
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
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
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
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
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
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
Example frequency band scan (spectrogram) Regional ITU Workshop, Amman, 5 - 7 December 2011
Example frequency channel ocupancy Regional ITU Workshop, Amman, 5 - 7 December 2011
Spectrum mask measurement Regional ITU Workshop, Amman, 5 - 7 December 2011 21
T-DAB 227 MHz Regional ITU Workshop, Amman, 5 - 7 December 2011
PMR 460 MHz Regional ITU Workshop, Amman, 5 - 7 December 2011
GPS jammer, 1,5 GHz Regional ITU Workshop, Amman, 5 - 7 December 2011
Digital networkfor the police 380 – 390 MHz Regional ITU Workshop, Amman, 5 - 7 December 2011
Wimax 3.4 – 3.6 GHz20102011 Regional ITU Workshop, Amman, 5 - 7 December 2011
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
Effect of a hectic incident Regional ITU Workshop, Amman, 5 - 7 December 2011
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
Theory versus practical Regional ITU Workshop, Amman, 5 - 7 December 2011
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
