WIRELESS COMMUNICATION DEVICE, WIRELESS COMMUNICATION SYSTEM, AND BEAM DIRECTION CORRECTION METHOD

Title:

WIRELESS COMMUNICATION DEVICE, WIRELESS COMMUNICATION SYSTEM, AND BEAM DIRECTION CORRECTION METHOD

Document Type and Number:

Japanese Patent JP2022085309

Kind Code:

A

Abstract:

To correct the direction of a beam of a wireless signal to an appropriate direction even when environmental condition data detected by an environmental sensor of the own device is not normal.SOLUTION: Environmental state data detected by each environmental sensor of a plurality of wireless communication devices is acquired, beam direction data indicating the beam direction of the wireless communication performed by a wireless communication unit is detected, wireless communication quality data indicating the wireless communication quality of wireless communication performed by the wireless communication unit is detected, a correction method of the beam direction in the next communication period of the communication period is obtained on the basis of the acquired environmental state data, a function that outputs a beam direction correction measure obtained in advance from the detected beam direction data and wireless communication quality data, beam direction data detected during a certain communication period, and the environmental condition data acquired during the communication period, an optimum beam direction correction direction is selected from the obtained beam direction correction measure, and the wireless communication unit is caused to correct the beam direction on the basis of the selected correction direction.SELECTED DRAWING: Figure 2
