Summary:
The aim of this study is to develop an accurate and reliable method to estimate field distributions in train cars so as to advance radio link design of wireless LANs operating inside the cars. This paper describes effects of reflected waves due to tunnel wall and/or train passing on opposite track on propagation characteristics inside the high-speed train cars in a typical railway tunnel. Field distributions created by a 2.4 GHz-band wireless transmitter inside cars are analyzed and exemplary propagation characteristics are determined statistically from large-scale numerical analysis results.
