- W805405315 abstract "Abstract For Effective and systematic response to disasters, needs of broadband multimedia services in wireless communication of PPDR(public protection and disaster relief) is increasing gradually. Recently in Korea, by the digital television transition, Korea Communications Commission is considering whether the freed spectrum can assign additional spectrum of PPDR or not. In this paper, we were defined the input parameters, were estimated the spectrum of requirements for Korean wireless communication of PPDR based on M.1390 methodology recommended by ITU-R. Key Words : Spectrum Requirements Estimation, PPDR. * 정회원, 행정안전부 재난안전정책과 ** 준회원, 공주대학교 정보통신공학과 *** 정회원, 홍익대학교 전자전기공학부 **** 정회원, 공주대학교 정보통신공학부(교신저자)접수일자 2011.5.18, 수정완료 2011.7.20게재확정일자 2011.8.12 Ⅰ. 서 론 최근 자연적이거나 인위적인 재난재해가 급증함에 따라 급속히 발전되고 있는 정보통신 기술을 PPDR(public protection and disaster relief) 무선통신에 접목하여 보다 효율적이고 체계적인 재난관리 시스템을 구축하고자 하는 것이 국가 차원의 주요 과제로 인식하고 있다. 이에 따라 전 세계 여러 국가들은 ITU-R 권고에 따라 ‘공공안전 및 재난구조(이하 ‘PPDR’)’ 무선통신용 주파수의 추가 확보와 공통주파수 지정을 논의하고 있다. 하지만 국내의 경우에는 오래전부터 경찰, 소방, 산불진화, 민방공, 홍수통제, 행정통신 등 각 소요기관별 용도에 따라 주파수가 산재되어 운영되고 있다. 따라서 주파수 자원 낭비뿐만 아니라 재난발생시 현장대응기관간 협업도 현실상 불가능하다" @default.
