| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The mobile networks become almost useless under large-scale disasters due to physical damage of mobile base stations, electricity outage, and traffic congestion. In addition, many areas were isolated due to the total damage of roads, harbors, and communication infrastructures. In these situations, satellite communications have attracted attention as an effective means of communication. When the 2016 Kumamoto earthquakes occurred, National Institute of Information and Communications Technology (NICT) dispatched an Earth Station in Motion that had been developed for WINDS to the affected area to establish and operate the emergency network. Furthermore, we operated voice communications together with the emergency network. In this paper, we introduced a voice communication system using an Internet satellite communication network, conducted sound quality evaluation, compared with the sound quality of satellite mobile phone, and reported the results. | |
