Abstract (in Japanese) (See Japanese page) 
(in English) In the event of large scale disaster such as the great east Japan earthquake, we completely lose the terrestrial communication infrastructure and have no measure to call the outside of the disaster area. Satellite communication is only an exception and is usable in such a situation. We have developed a portable multi-mode very small aperture terminal (VSAT) system for disaster-resilient wireless networks. In order to realize multi-mode functionality, the VSAT indoor unit (IDU) has been developed based on the software defined radio (SDR) technology. It can be used as a wireless-local area network (W-LAN) router connected to the cellular system in the normal situation. In the case of the disaster, the connection will be changed to the satellite communication route and will provide the Internet environment to the evacuees nearby this VSAT IDU. It can also provide the dual-connection; one is Internet connection via private VSAT network and another is the local authorities satellite communications network system connection via LASCOM network.
