Abstract

In a wireless communication system, increasing the channel capacity with a limited frequency is a problem in all frequency bands. Increasing the frequency bandwidth and increasing the output can increase the channel capacity, but sometimes the communication is not possible due to interference noise. If the radio frequency allocation is set to world standardization such as WRC or ITU-R, each country has strict control over regulations. This is because one wireless communication system should not affect other systems. We present the results of a study on scenarios and analysis of radio waves to be installed inside and outside the aircraft without interfering with the wireless LAN.

무선통신 시스템에서는 부족한 주파수를 가지고 채널 용량을 늘이는 분야는 활발하게 연구되고 있다. 주파수 파워를 높이고 밴드폭을 늘리면 채널 용량은 좋아지지만 노이즈 간섭을 일으킴으로 통신이 안 될 수도 있다. 무선주파수 할당은 한 무선통신 시스템으로 말미암아 타 무선통신시스템에 간섭이 없게 하기위해 법적인 효력을 갖는 표준을 통해 정부차원에서 관리하고 있다. 본고에서는 항공기에서 간섭없이 무선 랜을 구축시 여러 파라메터를 만족해야하는 지를 분석을 통해 제시하고자 한다. 이를 위해 시나리오를 바탕으로 전파 분석을 시뮬레이션해서 항공기 내부와 외부건물이 있는 경우의 이격거리를 얼마로 해야 간섭없는 송신기 설치가 가능한지에 대한 연구이다.
