On July 29, 2015, JAXA and NICT offered the Internet environment with asatellite when the Japan Medical Association (JMA) conducted the “satellite use demonstration in a prediction of the Nankai Trough earthquake (Disaster preparation drill) 2015.” The communication environment was established by setting up a ground station in each JMA prefectural office under the assumption that communication lines were cut off due to a large-scale disaster. We transmitted high-definition images from a sma... |

Characteristics of Wideband InterNetworking engineering test and Demonstration Satellite "KIZUNA" (WINDS)
KIZUNA satellite communication system uses the latest technology to create a faster, more efficient and more convenient communications environment.
|
KIZUNA will lead to ultra-high speed international Internet-based communications. The technology takes advantage of the fact that satellite communications are far-reaching, multicasting, and disaster-resistant. It will enable high-speed, large-volume data transmission, allowing ultra-fast domestic and international Internet-based communications, in particular between Japan and its neighboring countries in the Asia-Pacific region. Ultra-fast satellite-based Internet-based communications will remove the so-called digital divide by providing high-speed Internet service in areas where the terrestrial communications infrastructure is poor. Among other uses, this will make possible great advances in telemedicine, which will bring high-quality medical treatment to remote areas, and in distance education, connecting students and teachers separated by great distances. |
