| Abstract(in English) | The spread of IoT device requires appropriate wireless area design．Especially in IoT device it is often used indoors is considered that the propagation characteristics are influenced by the building materials and building structures．So for the estimation of the propagation loss in the indoor，it is important to know the electric properties of building materials and building structures made of a composite material．ITU-R P.1238 presents an average propagation loss of a typical indoor environment，but the differences in building materials is not considered．In this paper，we focus on a reinforced concrete as a composite material was investigated perform numerical analysis and the actual measurement．As a result，intended to report the 920MHz band for the difference of the radio wave transmission characteristics due to the spherical wave and plane wave． |
