Presentation

• Objectives of ITU-R Study Groups
• Structure of Study Groups
• Radiocommunication Assembly
• Scope of Study Groups
• CPM - Conference (WRC) process
• ITU-R Recommendations, Reports and Handbooks
• Conclusions

3
Role of ITU-R

• - ensure the rational, equitable, efficient and
  economical use of the radio-frequency spectrum by
  all radiocommunication services, including
  satellite services,
• - carry out studies without limit of frequency
  range on the basis of which Recommendations are
  adopted.
• (ref. Article 12 of Constitution)

4
Role of ITU-R

• Role conducted through (inter alia)
• World and Regional Radiocommunication Conferences
• Approval of Recommendations by Member States
• Technical studies are required
• which are conducted in Study Groups

5
Objectives of ITU-R Study Groups
Develop technical bases for WRCs and RRCs
e.g. CPM process for WRCs
Develop Recommendations

• International voluntary Standards on
• spectrum management
• system characteristics and operation

ITU-R represents International focal point for
standardization of wireless systems
Compile Reports and Handbooks
