Title:
RELAY STATION INSTALLATION POSITION CALCULATION APPARATUS, RELAY STATION INSTALLATION POSITION CALCULATION METHOD, AND RELAY STATION INSTALLATION POSITION CALCULATION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/157173
Kind Code:
A1
Abstract:
A relay station installation position calculation apparatus according to one embodiment of the present invention comprises: a first specification unit for specifying the position of a station placement candidate point where an LOS region from a relay station becomes maximum; a next candidate point extraction unit that uses the position having been specified by the first specification unit as a radio wave transmission point and extracts the second or lower order next station placement candidate points where the LOS region for the next relay station becomes maximum; a correction unit for correcting, on the basis of a Fresnel zone for the next relay station, each of the positions of the next station placement candidate points extracted by the next candidate point extraction unit; and a second specification unit for specifying, as a next relay station installation position, the position of a next station placement candidate point where the reflection angle of a radio wave toward a next station placement candidate point becomes minimum, among the next station placement candidate points of which the positions have been corrected by the correction unit and the next station placement candidate points extracted by the next candidate position extraction unit.
