5-5 地下鉄トンネル内の電波伝搬シミュレーションについて : SFP地下鉄実験より(第5部門 電波遮蔽空間の伝搬解析)

抄録

We estimated the radio propagation characteristics of 500MHz band in subway tunnel using ray-tracing method. We concluded that the estimated inclination of propagation loss matched with measured data within 60m and that the estimation error of vehicle body loss was about 4 dB.
