In applying radio technology and network technology to railway systems, it is essential to evaluate their characteristics in advance. We have developed a program to estimate radio propagation characteristics between mobile stations as well as those between a mobile stations and a fixed station, and verified that the calculated characteristics coincided with the substantial measured one. We also measured the propagation characteristics at frequencies of general-purpose radio at a station and at a location along railway lines indicating the conditions required upon the usage. In action, we clarified transmission characteristics of ad-hoc network technology adaptable to railways systems by a simulation.
