Title:
RADIO WAVE PROPAGATION ESTIMATION DEVICE AND RADIO WAVE PROPAGATION ESTIMATION METHOD
Document Type and Number:
Japanese Patent JP2023004867
Kind Code:
A
Abstract:
To provide a radio wave propagation estimation device and a radio wave propagation estimation method capable of effectively reducing errors and an amount of calculation in power calculation of radio waves arriving at a receiving point.SOLUTION: A radio wave propagation estimation device uses identification information that can identify an object including a structure and map data including the structure, and based on the identification information, extracts the structure of the object visible from both of a direct or simulated radio wave transmitting point and a direct or simulated radio wave receiving point. The radio wave propagation estimation device uses information indicating features of the extracted structure of the object and estimates radio wave propagation characteristics.SELECTED DRAWING: Figure 16
