ITU-R objective
• “…to ensure rational, equitable, efficient
and economical use of the spectrum by all
services, ……
• …to carry out studies and adopt
Recommendations on radiocommunication
matters”
ITU-R objective
Objective achieved through (inter alia):
•
•
World (and Regional) Radiocommunication
Conferences
Approval of Recommendations
Technical studies are required
which are conducted in Study Groups
