AI Technical Summary

⚠Technical Problem

Radio wave interference occurs between antennas when the directional beam of an antenna is changed relative to a flying object, disrupting communication for both the flying object and terminal devices within the communication area of the base station.

⚗Method used

A frequency band determination device that estimates the type of data transmitted and received by terminal devices in the communication area of other antennas and determines the frequency band for the antenna during directional changes, using an estimation unit and a determination unit to prevent interference.

🎯Benefits of technology

Prevents radio wave interference between antennas by dynamically adjusting frequency bands, ensuring continuous communication for both flying objects and ground-based terminal devices.

Abstract

To prevent radio wave interference with other antennas when a directivity direction of an antenna with respect to a flying object is changed.SOLUTION: A management device 10 determines a frequency band of radio waves transmitted and received by an antenna A of a base station B. An estimation unit 112 estimates in advance a type of data transmitted and received by a terminal device T located in a communication area of another antenna A located around a tracking antenna during a period in which the tracking antenna changes its directivity direction following a flying object F. Based on an estimation result by the estimation unit 112, a frequency band determination unit 114 determines the frequency band of the radio waves transmitted and received by the tracking antenna during the period in which the tracking antenna changes its directivity direction.SELECTED DRAWING: Figure 9A
