다양한 분야에서 드론의 용도와 활용성이 증가하면서 저고도 무인비행장치 교통관리체계 (UTM) 구축의 필요성이 제기되고 있다. UTM 통신으로 기존 LTE 상용망을 이용하는 경우 지상 사용자 대비 차이점은 드론이 비행하는 고도가 상대적으로 높다는 점으로, LTE 통신시스템은 지상에서 최적의 성능을 제공하기 위한 셀 구성이기 때문에 높은 고도에서의 성능은 보장하지 않는다. 따라서 기존 LTE 인프라를 활용하는 경우에는 무인 비행체의 경로에 따라 모든 구역에서 통신 서비스가 가능한지 판단할 수 있어야 한다. 본 논문에서는 영월 드론전용비행시험장에서 LTE 망의 상공 통신 품질 측정을 수행한 결과를 제시하고 UTM 통신으로 활용성에 대해 분석하였다.
