2 500~2 690MHz 대역은 전 세계적으로 우주업무와 지상업무가 공동으로 이용하는 대역으로서, 한정된 전파자원의 환경 하에서 이 주파수 대역의 공유 문제가 이슈로 대두되었다. 이와 관련하여 국제전기통신연합의 전파통신부문(ITU-R) 최고 의결 회의인 세계전파통신회의(WRC)에서는 ITU-R로 하여금 이 주파수 대역의 공유를 위한 기술적/규정적 연구를 수행하게 하였고, 이 연구결과를 토대로 2007년 10월에 개최되는 WRC에서 관련 규정을 제/개정할 예정이다. 본 고에서는 ITU-R에서 수행된 주파수 공유 연구 결과, 각 국가/기구의 입장 및 2007년 7월 부산에서 개최된 아/태 지역 WRC 준비그룹의 최종 회의 결과 등을 분석하고 향후 대응 방안을 고찰하였다.
