Abstract: The present invention performs: generating base station positional relationship specification data indicating a positional relationship between travel trajectory and a base station candidate position, and terminal station positional relationship specification data indicating a positional relationship between the travel trajectory and a terminal station candidate position, based on travel trajectory data indicating the travel trajectory of a moving body for measuring an object present in a three-dimensional space within a measurable distance predetermined and acquiring point cloud data indicating a position of the object measured in the three-dimensional space, the measurable distance, base station candidate position data indicating a candidate position for installing a base station apparatus, and terminal station candidate position data indicating a candidate position for installing a terminal station apparatus; and specifying a reliability coefficient indicating a degree of reliability of a processing result

Abstract: A line-of-sight determination method includes: a point cloud data acquisition step of acquiring point cloud data including a first position indicating a position of a first wireless station and a plurality of second positions indicating positions on a structure serving as a candidate in which a second wireless station opposing the first wireless station is to be installed; and a line-of-sight determination step of determining whether or not there is a line of sight between the first position and at least one of the second positions, and determining whether or not there is a line of sight between the first wireless station and the structure based on the determination result.

Abstract: A wireless communication system has a communication control device and a plurality of wireless communication devices. The communication control device transmits, to one of the wireless communication devices, information regarding a measurement target device that is another one of the wireless communication devices with which interference power is to be measured. Each of the wireless communication devices includes a wireless unit, a power measurement unit, and a communication control unit. The wireless unit forms a beam and transmits and receives a wireless signal using the formed beam. The power measurement unit measures power of a wireless signal received by the wireless unit.

Abstract: In two-dimensional map data showing buildings to be candidates in which terminal station devices are to be installed, a position of a base station installation structure to be a candidate in which a base station device is to be installed is set as a base station candidate position, an unobstructed view for each of the buildings from the base station candidate position is determined based on the map data while excluding a region blocked by the building having an unobstructed view from the base station candidate position, and a range of a contour line having an unobstructed view of the building determined as having the unobstructed view is detected as an unobstructed view range. A candidate of, among wall surfaces of the building corresponding to the detected unobstructed view range, the wall surface on which the terminal station device can be installed is extracted.

Abstract: On two-dimensional map data indicating buildings serving as candidates for installing terminal station devices, locations of base station installation structures serving as candidates for installing base station devices are set as base station candidate locations, and for each of the base station candidate locations, buildings that have other buildings between themselves and the base station candidate location are selected as visibility detection subject buildings. The heights of the buildings are set at an identical length, a higher position than the buildings is set as an installation altitude of the base station devices, and for each selected visibility detection subject building, a visibility range of the visibility detection subject building from the installation altitude of the base station device in the base station candidate location is detected.
