Abstract

LTE-maritime, which was built as part of the Korean e-Navigation project, has been providing a service that meets the goal of establishing a network up to 100km from the coast since J anuary 31, 2021. To provide appropriate communication services for LTE-maritime from the perspective of real users, additional performance analysis of LTE-maritime is required considering service implementation, and efficient use of spectrum resources. This paper presents the requirement of transmission speed according to the e-Navigation service scenario, and available transmission speed based on LTE modulation coding scheme (MCS) according to sea-specific ship distribution scenario and frequency resource allocation, and is cross-analyzed with results of the sea test.

한국형 이내비게이션 사업의 일환으로 구축된 초고속해상무선통신망(LTE-maritime)은 '21년 1월부터 해안으로 부터 최대 100km 해역까지 품질목표를 만족하는 통신 서비스를 제공하고 있다. 실 사용자 관점에서 적절한 초고속해상무선통신망의 통신 서비스 제공을 위해서는 서비스 구현과 효율적 주파수 자원 활용을 고려한 추가적인 통신망 성능 분석이 필요하다. 본 논문은 해역별 어선의 입출항 및 조업 형태 등을 고려한 선박분포를 고려하여 이내비게이션 서비스 시나리오에 따른 요구 전송속도와 주파수 자원 할당에 따른 LTE 변조코딩방식(MCS) 기반 제공 가능한 통신 속도를 산출하고, 실해역 성능 품질 측정 결과와 교차 분석하였다.
