Outline of Final Research Achievements

Mobile phone network performance has been improving year-by-year, and attention is now being paid to the utilization of such devices at sea, which has not been extensively explored to date such as remotely vessel controlling and autonomous ship. Wireless communication technology is important for these systems, and it is known that available on the coastal waters, however communication at sea does not achieve sufficient performance compared to use on land.
In this research, we have developed a multi-path communication control method that can achieve good communication quality at sea. (1) Development of a multi-path communication control method that simultaneously uses multiple lines based on actual communication environment measurement at sea (performance survey by LTE band) and the results. (2) Development of high-definition video transmission and data volume reduction method assuming remote control using machine learning.

Academic Significance and Societal Importance of the Research Achievements

複数の通信回線をその通信特性や通信環境に応じて併用する技術は、現在主流の使われ方である接続が確立された回線から1本を主な通信経路として用いる場合と異なり、1本の回線では実現が難しい性能を環境に適応的に提供できる可能性を備えている。この技術を海洋開発分野における高度なICTシステムの通信基盤とすることで、これまでには無い新しい産業の創出が期待できる。無線通信は数年～10年周期で新しい規格が登場し置き換わっていく変化が急な技術であり、その通信特性も大きく変化する。複数回線の連携・併用技術はその時代で提供される無線通信の特性考慮により様々な技術開発が可能な将来性のある分野であると考えている。
