ITU World Radio Conferences An Overview.

Presented by John A. C. Breen Department of Communications, Marine & Natural Resources

Scope of Presentation

• Why hold a WRC • Function of a WRC • Role of the Department • Sectors involved & Agenda items • Preparation • Participation (Irish team make up) • Outcome of WRC • EC and ITU Conferences ( Issues that can arise for the Presidency) 2

Why hold a WRC (1)

• The Spectrum is an International Natural Resource • It is used by a multiplicity of different services.

• Radio Waves do not stop at National Borders.

• Technology & market developments in Radiocommunication is rapid.

• New services & applications need access to spectrum.

• Licensees & consumers expect and normally obtain interference free use 3

Why hold a WRC (2)

• The procedures for use of spectrum constantly need to be reviewed & updated. • National use of the radio spectrum is governed by International Treaty called the ITU Radio Regulations.

• WRC’s are the mechanism to update the International Radio Regulations 4

Uses of the Radio Frequency Spectrum

Mobile Radio

Maritime and Aeronautical Mobile Telephony business (e.g.. Taxis) Public Utilities and Emergency services

Radio Links

Point to Point Links Point to Multipoint Links

Navigation

Radionavigation RadioLocation Terresrial or Satellite

Broadcasting

Television Radio

Satellite Scientific Uses

Radio Astromony Standard Time Signals Meteorological & Earth Exploration

Communications Leisure Uses

Amateurs CB Model control etc.

WRC Functions

• To update the International Radio Regulations: – Revision of the allocations of spectrum to the different Radiocommunications services.

– Revise any frequency assignment or allotment plans that form part of the Radio Regulations.

– To modify and update the rules and procedures governing access and use of the radio spectrum.

– Address any radiocommunications matter of a worldwide nature. – Identify topic for study by the ITU study groups in preparation for future conferences.

6

Terms specific to frequency

• Allocation

management

relates to Service (Spectrum Policy framework both Internationally & Nationally)

• Allotment

relates to Area or Countries (Policy – Planning/International level)

• Assignment

relates to Stations (Policy – Planning/International level) (Implementation – Licensing & Plan modification) 7

Spectrum Policy Pyramid

ITU -WRC EU CEPT & ETSI National Administrations National Regulators Global Level:- International policy including segmenting of spectrum between the different services & general procedures for use Regional Level:- Regional/European policy (harmonisation) e.g. Channel Plans, Equipment Specifications & Regional Rules for use National Radiocommunications & Spectrum Policy Licensing & Enforcement

8

WRC & role of the Department

• International Agreements fall within the Remit of the Minister. WRC Final Acts is such an Agreement.

• Oversee the national preparation for WRC – Coordinating the requirement of the different sectors (National Preparatory Group) – Seek compatability between sector policy and Radiocommunications/spectrum policy – Input to the European preparations • Lead and coordinate the WRC delegation.

• Arrange for laying the Final Acts before the Dail.

• Identify any resulting policy or legislative changes 9

WRC-03 Agenda items

• Over 40 separate agenda items (Some item required in the short term, some long term & some items are evolving over a period).

• Sectors involved include: Telecommunications, Broadcasting, Transport (Aeronautical & Maritime), Security, Science & Leisure (Note: On the following slides topics marked with a ** are items identified in the EC communication as important items for EU policy).

10

Agenda items (1)

(Telecoms) (a)

• Public Protection & Disaster Relief. ** (Harmonised bands & Regulatory provision) • Allocations around 5 GHz for Mobile & Fixed (RLANs) and sharing with existing services. ** • Consider ITU studies on future developments in IMT2000 and systems beyond IMT2000. ** • Consider ITU studies on Terrestrial Wireless Multimedia Applications (TWIMS) 11

Agenda items (2)

(Telecoms) (b)

• High Density systems in the Fixed Satellite service. Identify bands above 17 GHz.

• High Altitude Platforms (HAPs). Frequency Allocation & Regulatory provisions. • Earth Stations (Telecoms services) on ships and sharing the band with terrestrial services.

• Consideration of studies concerning the satellite service and sharing with other services.

IMT 2000 & Systems Beyond

14

IMT 2000 & Systems Beyond

Enhancements to IMT-2000 Future Enhancement of the Terrestrial IMT-2000 capabilities will continue at least for the next 10 years:

•

Increased communication speeds up to about 30 Mbit/s

•

Increasing relationship with other systems (e.g., WLAN, digital broadcasting and satellite)

•

Towards IP-based networks

Systems Beyond IMT-2000 Mobile access element will handle wide range of supported data rates up to approximately 100 Mbit/s

•

New Wireless access methods

•

Full area coverage in multi-user, multi-cell environments, terminals moving at vehicular speeds (high mobility) (Figure 7.2-1)

15

Agenda items (3) (Broadcasting)

• Digital standards for use on the HF (shortwave) band.

• Considerations of studies on the adequacy of HF (shortwave) bands.

• Satellite Broadcasting –review of regulatory procedures for sharing 12 GHz band.

16

Agenda items (3)

(Aeronautical & Maritime) (a)

• Update of the Regulations to take account of the transition to the Global Maritime Distress & Safety System (GMDSS) • Address the Exhaustion of the Maritime Mobile Service Identity (MMSI) numbering Resource.

• Address shore-to-ship distress communication priorities.

17

Agenda items (4)

(Aeronautical & Maritime) (b)

• Use of Digital Technology in the MF & HF Maritime bands.

• Address harmful interference in bands allocated to Aeronautical & Maritime Service.

• Use of Aeronautical VHF radionavigation band for radionavigation satellite differential correction signals. • Sharing between existing (GPS) and new navigation satellite systems (Galileo). ** 18

Agenda items (5) (Science Services)

• Protection of Passive Services (Radio Astronomy and sensors for the Earth Exploration Satellite Service (EESS)) • UHF frequency allocation for the EESS for environmental measurements.

• Frequencies for space research service 19

Agenda items (6) (Amateurs)

• Update of the Regulations governing the Amateur & Amateur Satellite Service.

• Consider the realignment of allocation to the amateur service in the Shortwave band (7 MHz) and consequential adjustments to the allocations for the broadcasting service. 20

Agenda items (7)

(General)

• General tidying up of the Radio Regulations : – Deleting of country footnotes – Updating or deleting of resolutions from previous conf.

• Review of unwanted emission: – Updating definitions & regulatory provisions – Updating of permitted levels.

• Agenda for next conference (WRC-07) and preliminary views for future conference.

21

Preparation for WRC

• WRC will be held in June 2003 (4 weeks) • ITU study groups have prepare a report outlining the different options for the various agenda items.

• Europe (CEPT) established a Conference Preparatory Group (CPG).

• EC worked with CEPT CPG to reflect EU policy on spectrum matters.

• CEPT CPG developed ECP’s (European Common Proposals) for WRC03. (35 ECPs) (IRL supports 34).

• A National Preparatory Group (NPG) was established by the Department.
