모바일 데이터의 기하급수적 증가와 조밀해지는 기지국 밀도로 인해 이동통신 무선 접속 네트워크의 프론트홀(Fronthaul)과 미드홀(Midhaul), 백홀(Backhaul)의 신규 구축 및 증설이 요구되고 있다. 그러나 기존의 유선 솔루션으로는 통신 사업자의 수익이 데이터량에 비례하여 증가하지 못하기 때문에, 무선접속망의 구조적 유연성을 증대시키고 통합적 관리를 제공하여 다양한 이동통신 서비스를 제공하고 통신 사업자의 비용 효율성을 제고할 수 있는 새로운 개념의 기술이 필요하다. 이를 위해, 본 논문에서는 설치 유연성과 이동 무선접속망을 지원할 수 있는 이동 엑스홀 네트워크(MXN, Mobile xHaul Network)의 구조 및 통합 무선전송링크인 xHaul 링크의 전송 방식을 설계하였다. 또, 시스템 수준의 시뮬레이션을 통해 다양한 시나리오에서 Xhaul 링크의 전송 성능 평가를 수행하였다. 성능 평가의 결과 설계한 Xhaul 링크는 최대 20Gbps이상의 성능을 제공할 수 있으며 이는 5G 전송 요구사항을 만족함을 알 수 있었다.
