Summary:
The aim of this study is to develop an accurate and reliable method of estimating field distributions in train cars so as to advance radio link design of wireless LANs operated inside the cars. This paper describes effects of absorption and shielding caused by a large number of passengers on propagation characteristics of RF leakage from wireless access point operating in a bullet train. Field distributions created by a 2.4 GHz-band wireless transmitter inside cars, when oncoming train cars are passing through a double track railway tunnel, are analyzed and propagation characteristics are determined from the analysis results
