Abstract
세계 각 국은 Mobile WiMAX 주파수를 다양한 대역에서 도입을 시도하고 있다. 특히 2.5 GHz 대역은 WRC에서 정한 IMT-2000 추가 대역으로 향후 이동통신용으로 사용될 것으로 전망되며, Mobile WiMAX 등 글로벌 무선광대역서비스 제공이 가능한 대역으로 주목받고 있다. 그런데, 국내 기술인 WiBro의 세계시장 진출 기반 조성을 위하여 ITU-R 산하 WP8F 회의에서 Mobile WiMAX를 IMT-2000 기술 표준으로 포함시키기 위한 활동을 전개 하였으며, 최근 ITU-R 전파통신총회에서 한국의 WiBro 기술을 3G 기술 표준으로 최종 승인했다. 이에 본 고는 주요국의 2.5 GHz 대역 이용계획과 WiBro 기술의 IMT-2000 표준 채택에 따른 시장의 변화를 알아보고자 하였다.
