Claims (3)
- 무선망 설계시스템에 적용되는 전송손실 예측 방법에 있어서,해석의 대상이 되는 전파환경 파라미터를 설정하는 제 1 단계;처음 계산되는 방향에 대하여 소정 간격으로 가시지역(LOS) 전송손실값(PL_LOS(d))을 계산하는 제 2 단계;상기 가시지역 전송손실값(PL_LOS(d))을 거리 및 손실값의 표의 형태로 컴퓨터내의 기억공간에 저장하는 제 3 단계;기지국과 수신점 사이에 장애물이 있는지를 판단하는 제 4 단계;상기 제 4 단계의 판단결과, 장애물이 없으면(즉, 가시지역에 있으면) 상기 기억공간에 저장된 가시지역 전송손실값(PL_LOS(d))에 영을 더하여 전체 전송손실값을 구하는 제 5 단계;상기 제 4 단계의 판단결과, 장애물이 있으면(즉, 비가시지역에 있으면) 상기 기억공간에 저장된 가시지역 전송손실값(PL_LOS(d))에 건물에 의한 전송손실값(PL_Building)을 더하여 전체 전송손실값을 구하는 제 6 단계; 및전체 방향에 대해 계산된 전송손실값을 출력장치에 출력하여 최종 서비스 영역을 도시하는 제 7 단계를 포함하여 이루어진 전송손실 예측 방법.
- 제 1 항에 있어서,제 2, 3, 5, 및 6 단계의 가시지역 전송손실값(PL_LOS(d))은 각각,거리에만 의존하도록 하여 거리가 같은 수신점에서의 가시지역 전송손실값(PL_LOS(d))은 동일하게 취급되어 다른 방향 해석시 그대로 사용되는 것을 특징으로 하는 전송손실 예측 방법.
- 제 2 항에 있어서,상기 제 4 단계 및 제 5 단계는 각각,지형의 영향을 받지 않기 때문에 기지국으로부터 가시지역(LOS : Llne Of Sight)에 있을 경우의 전체 전송손실값(PL)은 가시지역 전송손실값(PL_LOS(d))이되고, 건물들에 가려져 기지국으로부터 비가시지역(NLOS)에 있을 경우의 전체 전송손실값(PL)은 상기 가시지역 전송손실값(PL_LOS(d))에 건물에 의한 전송손실값(PL_Building)을 더한값인 것을 특징으로 하는 전송손실 예측 방법.
