최근 주요국에서 주파수 자원 개방의 일환으로 TV White Space(TVWS) 관련 정책이 추진되고 있으며, Super-WiFi 및 WRAN을 통한 활용 방안이 중점적으로 논의되고 있다. 이는 이동통신 서비스의 주파수 부족 문제 해소 차원 외에도 비면허 및 저대역 주파수를 사용하는 특성으로 인해 신규 서비스의 등장과 다양한 산업이 개발되고 육성되는 기반이 될 수 있다는 점에서 비(非) 통신계 사업자에게는 큰 기회가 되고 있다. 이에 DB 기반의 TVWS 상용 및 시험 서비스가 가시화됨에 따라 주요국에서 등장하는 TVWS 서비스 현황을 살펴보고, TVWS 서비스의 생태계 분석을 통해 향후 국내 시장환경에 적합한 White Space 서비스 도입 방안 제시와 함께 DB 운영 및 이용자 측면에서 바람직한 상용화 정책 방향을 모색하고자 하였다.
