In recent years, the maritime industry has actively proceeded with research and development on technologies related to maritime autonomous surface ships (MASS) and their remote operation systems. Demonstrations of these technologies have been carried out using actual vessels. At the same time, individual technological elements related to MASS have also been developed. Among these technological advances, those associated with cyber security are of particular importance. This paper investigates the use of 'LTE over IP' which is designed to ensure secure communication by enabling LTE technology for mobile phones to be used in IP networks. The authors examined how the use of 'LTE over IP' affects the communication characteristics of a remote-control system.
