This change accompanies the formulation of a new corporate identity for the Docomo Group, aiming to leverage synergy with the Docomo Business Group and enhance value delivered to customers.
NTT World Engineering Marine will commence operations of the submarine cable laying vessel 'CS VEGA II', registered in the Philippines, from April 2025. It will primarily be used for maintenance of international submarine cables within the Philippines and its surrounding waters, enhancing the country's cable maintenance system and the stability of its communication infrastructure.
In May 2023, NTT‑WE Marine and Skypower JSAT introduced the satellite communication service "JSATMarine Light" on the crew transport vessel "RERA AS", owned by NYK Line, intended for offshore wind power generation. The vessel is expected to use it for ship‑to‑shore business communications and crew welfare. The adopted plan offers best‑effort downlink up to 3 Mbps and uplink up to 1 Mbps.
NTT-WE Marine and Skypower JSAT have agreed to commence the provision of the fixed-rate high-speed satellite communication service 'JSATMarine Light' for inland vessels. By combining it with 'Maritime Mobile A-II', which uses the LTE network, it achieves downlink speeds up to 150Mbps and uplink speeds up to 50Mbps (best effort) within LTE coverage, and automatically switches to satellite links outside coverage, ensuring stable communication between ships and land.
