Fecha de publicación: 29/12/2022 Fuente: WIPO (eseential oils OR extracts) This radiowave propagation estimation device uses identification information that can identify objects that include structures, and map data that includes structures, and, on the basis of the identification information, extracts object structures that are visible from both the direct or simulated transmission point of radiowaves and the direct or simulated reception point of radiowaves. The radiowave propagation estimation device uses information indicating the characteristics of the extracted object structure to estimate the radiowave propagation characteristics.
