Abstract: A plurality of ground station devices perform wireless communication processing for a side of a terminal station; and a single or a plurality of mobile station devices perform wireless communication processing for a side of a base station, so as to make a wireless connection in parallel with a plurality of the ground station devices having a line of sight.

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.
