e5 Lab Conducts Demonstration Test of High-speed
Satellite Communication System for Maritime Use

Ships
Ships forfor thethe futurefutureTOKYO—e5 Lab Inc. (President: Tomoaki Ichita; Headquarters: Chiyoda-ku, Tokyo) today
announced that it has completed a joint telecommunication test—using an existing high-speed
communication satellite—as the first phase of a demonstration test project aimed at improving
maritime broadband services. e5 Lab, which works to develop and commercialize zeroemission electrically powered vessels in cooperation with SoftBank Corp., is examining ways
to enhance maritime broadband services using existing communication satellites as well as
next-generation satellite technology. The goal of this project is to create a more effective
onboard telecommunications environment, a critical issue for Japan’s ocean shipping industry.
The joint test was conducted by nine companies including seven marine equipment
manufacturers, as well as SoftBank.
Using a high-speed data communication environment (maximum effective speed: 10Mbps),
the participating companies acquired the necessary onboard data related to their equipment,
and confirmed their ability not only to monitor but also control information on vessel operations
in real time from the shore side. They also verified new methods to operate associatedequipment and so on remotely, by analyzing large volumes of data transmitted to the shore
side. e5 Lab and other participants achieved better-than-expected test results, gaining
confidence as they work to develop the next phase of their businesses.
Based on the test results, e5 Lab and SoftBank will advance their joint research oncommercializing and promoting the widespread application of marine broadband services
using existing and next-generation communication satellites to drive the sustainable growth of
the Japanese ocean shipping industry while creating new value.
