The Great earthquake and tsunami in March, 2011 destroyed the communications infrastructure over wide areas in Tohoku regions. Great efforts were made for prompt recovery of the communication infrastructure; many emergency vehicles with power supply and transportable BTS functions were dispatched in the disaster areas. It was soon recognised that recovery of the damaged optical fiber entrance links would take so long that the demand for satellite communication suddenly surged. The satellite communication systems available in Japan were fully mobilized. IPSTAR system was also widely used for the entrances links for mobile communication operators and also for the Internet connections in the emergency facilities. The great natural disaster clarified the essential role of satellite communications for emergency situations. In this paper we will report how IPSTAR was used for the relief efforts, the problems encountered and propose new systems and applications of satellite communications for the future. |
