Abstract
Ⅱ. 기술개발결과 Ⅱ-1. 해상 광대역 무선 데이터통신 시스템 1. 해상 광대역 통신 시스템 전체 구조 및 기능 가. 시스템 구조 새로운 해상용 광대역 무선통신 인프라를 위한 기술로 위성통신, 기존의 해상통신, 지상통신이 있을 수 있다. 근원적으로 위성통신의 경우 가격을 낮추기가 힘들고 기존의 해상통신 또한 속도를 높이기 힘들다. 지상통신 기술은 통달거리에 대한 문제가 있지만 멀티홉 릴레이 기술과 고성능 AMP 개발 및 지향성 안테나를 이용하는 등의 통달거리 확장 기술로 통달거리 확장이 가능하다. 따라서 새로운 해상용 광대역 무선 통신 인프라를 위한 기술로는 고속 데이터 통신이 가능하고 가격이 저렴하면서도 신뢰성을 제공하는 지상의 무선통신 기술을 발전시켜 적용하는 것이 최적으로 판단된다.
