본 논문에서는 저궤도 위성망(LEO satellite network)과 FS 시스템(Fixed Service system)이 동일한 하향 링크 주파수를 사용하는 통신 환경에서 두 시스템이 간섭 영향 없이 운용될 수 있는 방안을 연구하였다. 저궤도 위성망에 의한 FS 시스템으로의 간섭 시나리오의 경우 동시에 운용되는 저궤도 위성 빔의 수에 따라 FS 시스템의 영역을 정의하여 각 영역에서의 간섭 영향을 분석하였다. 또한 FS 시스템에 의한 지구국으로의 간섭 시나리오에서는 지구국의 보호 영역을 정의하여 보호 영역의 반경에 따른 간섭 영향을 분석하였다. 분석한 결과는 두 시스템이 간섭 영향 없이 운용될 수 있는 공유 조건으로 FS 시스템의 설계 단계에 활용될 수 있다.
