Abstract

In this paper, we analyze the distance between two systems, WiBro and WLAN, compared to standard interference probability for channel co-use in order to be used as a criteria in realization. Co-channel and adjacent channel interference probability and its effect of (WiBro) into Wireless LAN (WLAN) in TV White Spaces (TVWS) is evaluated through Spectrum Engineering Advanced Monte Carlo Analysis Tool(SEAMCAT) based on the Monte-Carlo simulation method. As a result, in the case of co-channel interference, the minimum distance between WiBro Mobile Station(MS) and WLAN User Equipment (UE) should be 210 m to allow the maximum transmitter power of WiBro UE of 25 dBm. The transmit power of WiBro BS have to be reduced to -4.96 dBm.

본 논문은 채널 공유를 위한 기준 간섭확률 대비 두 시스템인 WiBro 와 WLAN간의 이격거리를 분석하여 상용화의 기준 자료가 되도록 하였다. Monte-Carlo 방법에 기초한 Spectrum Engineering Advanced Monte Carlo Analysis Tool(SEAMCAT)을 이용하여 TV White Spaces(TVWS) 대역의 동일 및 인접채널에서 WiBro가 무선랜에 미치는 간섭확률 및 그 영향을 분석하였다. 분석 결과, 동일채널에서 WiBro Mobile Station(MS)의 최대 송신파워(25 dBm)를 허용하기 위해 WiBro MS와 무선랜 User Equipment(UE) 사이에 210 m의 이격거리가 요구된다. 또한, WiBro Base Station(BS)의 송신파워는 -4.96 dBm으로 감소되어야 한다.
