  • 본 논문에서는 현재 우리 나라에서 사용하는 해양무선통신을 육상국을 중심으로 주파수, 서비스의 종류, 통신의 종류, 항만의 분포 둥을 조사 분석하였다. 특히 1998년 5월부터 서비스가 시작된 초단파대역의 해양이동전화에 대한 내용을 중점적으로 조사하여 기재하고 있다. 해양이동전화의 경우, 기지국의 위치, 망구축, 번호의 이용과 단말기의 보급, 서비스계획, 주요제원, 서비스의 특징 둥을 조사 분석하여, 새롭게 시작하는 해상이동전화에 대한 이해를 도모하였다. 일본에서는 1979년 3월부터 자동교환접속에 의한 해상이동전화서비스가 시작된 것과 비교해볼 때, 우리 나라의 해상이동전화서비스는 매우 늦은 감이 있지만, 도서지역 주민들에 대한 생활수준의 향상 둥에 많은 기여를 할 것으로 생각된다. 이러한 해상이동전화 서비스의 시작은 지역간 정보통신서비스제공의 불균형을 해소하고 낙후된 해안ㆍ도서지역의 통신서비스개선에 큰 역할을 담당할 것이다.

  • IMO has made AIS and VHF mandatory for international sailing vessels through SOLAS, and korea if mandating specific vessels through the law for safety of vessels and the ship installation technology standards. However, due to various communication equipments and complicated usage method, malfunction occurs, and the response delay to the actual structure signal often causes human accidents. So recently, as a part of GMDSS modernization, maritime communication devices are attempting to interwork and integrate different types of marine communication system in order to construct a next generation maritime communication system. In this paper, we describe a technique to implement the DSC function by interlocking and integrating the AIS device and VHF. We will present the basis for achieving domestic technical standards and standardization through the linking algorithm of the data that can extract the ship information from AIS and utilize it the DSC function of VHF.

  • Radio equipment for maritime service and navigation aids installed on fishing vessels are required to comply with the performance standards KN60945_60533 that apply IEC 60945. The LTE-M transceiver was excluded from the target because it did not belong to the radio equipment of the ship station, and it acted as a cause of audible noise in the radio equipment for maritime service installed in the fishing vessel due to interference by radiated emission or conducted emission. In this paper, we analyze the impact of interference based on related cases and present institutional solutions for the diversification of LTE-M.
