  1. RAS in KOREACurrent status

  2. Final Goals for Freedom • Challenge and Change • - Domestic and International Activities • (Technical studies and Political Actions) • - Needs for a Good Relationship with • Government Peoples and Active Services • Modify International Radio Regulations • Modify Domestic radio Law •  Registration RA sites

  3. What can WE do for Protection & Sharing Activities • Technical Studies • - Domestic Activities (Korea ITU-R) • - International Activities • : ITU-R (SG7, WP7D), CPM • Political Activities • - Domestic Activities (Korea WRC-12 WG4) • - International Activities • : WRC (/3-4 year) • : regional meetings(APG, RAFCAP, IUCAF)-/year

  4. Protection & Sharing Activities • Major Domestic Activities

  5. Protection & Sharing Activities • Major International Activities
