A. OBJECTIVES AND GENERAL INFORMATION

ITU-R/Study Group Structure

THE INTERNATIONAL TELECOMMUNICATION UNION

The International Telecommunication Union is a specialised agency of the United Nations, "responsible for the regulation and planning of worldwide telecommunication, the establishment of operating standards for equipment and systems, the coordination and dissemination of information required for the planning and operation of telecommunication services, and the promotion of and contribution to the development of telecommunication and related services." This work is carried out by three Sectors: the Telecommunication Standardisation Sector (ITU-T), the Radiocommunication Sector (ITU-R), and the Telecommunication Development Sector (ITU-D).

RADIOCOMMUNICATION SECTOR (ITU-R)

The Radiocommunication Sector is divided into a number of Study Groups which consider various topics, develop Recommendations (and other documents) and report back on this work to a two to three-yearly Radiocommunication Assembly and (via a Conference Preparatory Meeting) the World Radio Communication Conference. The ultimate goal of these Recommendations is to promote worldwide de facto standards for radio systems, to provide guidance in the allocation of frequencies to various services and to guide coordination and sharing among services in the same bands. Recommendations are useful to system designers and regulators, and in some countries are considered mandatory requirements for the planning and design of radiocommunication systems.

SCOPE OF ITU RADIOCOMMUNICATION STUDY GROUPS

__________________________________________________________

Study Group 1 - SPECTRUM MANAGEMENT (Chairman: Mr Rob Haines - USA)

Scope :

Spectrum management principles and techniques, general principles of sharing, spectrum monitoring, long-term strategies for spectrum utilization, economic approaches to national spectrum management, automated techniques and assistance to developing countries in cooperation with the Telecommunication Development Sector.

Study Group 3 - RADIO WAVE PROPAGATION (Chairman: Mr Bertram Arbesser-Rastburg - ESA)

Scope :

Propagation of radio waves in ionized and non-ionized media and the characteristics of radio noise, for the purpose of improving radiocommunication systems. The Study Group is divided into four Working Parties:

  • WP 3J: Propagation Fundamentals (Chairman: Prof. Marlene Pontes, Brazil)
  • WP 3K: Point-to-area Propagation (Chairman: Rainer Grosskopf, Germany)
  • WP 3L: Ionospheric Propagation and Radio Noise (Chairman: John Wang, USA)
  • WP 3M: Point-to-point and Earth-space Propagation (Chairman: Mrs Carol Wilson, Australia)

Study Group 4 - SATELLITE SERVICES (Chairman: Mrs Veena Rawat - Canada)

Scope :

Systems and networks for the fixed-satellite service, mobile-satellite service, broadcasting-satellite service and radiodetermination-satellite service.

__________________________________________________________

Study Group 5 - TERRESTRIAL SERVICES (Chairman: Mr Akira Hashimoto – NTT Japan)

Scope :

Systems and networks for fixed, mobile, radiodetermination, amateur and amateur-satellite services.

__________________________________________________________

Study Group 6 - BROADCASTING SERVICE (Chairman: Mr Christopher Dosch – IRT Germany)

Scope :

Radiocommunication broadcasting, including vision, sound, multimedia and data services principally intended for delivery to the general public.

Broadcasting makes use of point-to-everywhere information delivery to widely available consumer receivers. When return channel capacity is required (e.g. for access control, interactivity, etc.), broadcasting typically uses an asymmetrical distribution infrastructure that allows high capacity information delivery to the public with lower capacity return link to the service provider. This includes production and distribution of programmes (vision, sound, multimedia, data, etc.) as well as contribution circuits among studios, information gathering circuits (ENG, SNG, etc.), primary distribution to delivery nodes, and secondary distribution to consumers.

The Study Group, recognizing that radiocommunication broadcasting extends from the production of programmes to their delivery to the general public, as detailed above, studies those aspects related to production and radiocommunication, including the international exchange of programmes as well as the overall quality of service.

Study Group 7 - SCIENCE SERVICES (Chairman: Mr Vincent Meens – France)

Scope:

Systems for space operation, space research, earth exploration and meteorology, including the related use of links in the inter-satellite service .

Systems for remote sensing, including passive and active sensing systems, operating on both ground-based and space-based platforms.

Radio astronomy and radar astronomy.

Dissemination, reception and coordination of standard-frequency and time-signal services, including the application of satellite techniques, on a worldwide basis.

__________________________________________________________

CCV - COORDINATION COMMITTEE FOR VOCABULARY (Chairman: Mr Nabil Kisrawi  - Syria)

Scope :

Coordination and approval in close collaboration with the Radiocommunication Study Groups, the General Secretariat (Conferences and Publications Department) and other interested organizations (mainly the International Electrotechnical Commission (IEC)), concerning:

·         vocabulary, including abbreviations and initials;

·         related subjects (quantities and units, graphical and letter symbols).

__________________________________________________________

CPM - CONFERENCE PREPARATORY MEETING (Chairman: Mr Albert Nalbandian  - Armenia)

Scope :

The CPM shall prepare a consolidated report to be used in support of the work of World Radiocommunication Conferences, based on:

  • contributions from administrations, the Special Committee, the Radiocommunication Study Groups (see also No. 156 of the Convention), and other sources (see Article 19 of the Convention) concerning the regulatory, technical, operational and procedural matters to be considered by such conferences;
  • the inclusion, to the extent possible, of reconciled differences in approaches as contained in the source material, or, in the case where the approaches cannot be reconciled, the inclusion of the differing views and their justification.

__________________________________________________________

SC - SPECIAL COMMITTEE ON REGULATORY/PROCEDURAL MATTERS (Chairman: Mr Maurice Ghazal -Lebanon)

Scope :

Review of regulatory/procedural matters, the results of which may be used by administrations in their preparations for the next World Radiocommunication Conference.

Investigation of options for the study of regulatory/procedural matters, including but not limited to the use of a Working Party to the Conference Preparatory Meeting or a full ITU-R Study Group.
