概要
If the wireless communication is feasible in the concrete structure of power plants, it is effective for us to reduce the construction cost, improve the placement of equipment and change facilities easily. In buildings of such a power plant, the reinforced concrete (RC) walls might be more than one meter in thickness, with high rebar density. Therefore, radio wave transmission over this kind of concrete walls was studied to discuss feasibility. Aperture parts of walls, such as doors, whose thickness is less than transmission distances, are considered by the Finite-Difference Time-Domain (FDTD) calculations, and experiments with the similar structure in the actual building. As a result of the calculations and the experiments, we confirmed that the transmission radio wave over the RC structure would be feasible with lower frequency and vertically placed dipole antenna.
