The importance of connecting stability

Herunterladen, um offline zu lesen

ICT are a key infrastructure to establish economic and social systems in the present age.
The Great East Japan Earthquake made a hard impact to ICT facilities that was difficult to continue communication services in the disaster area.
Suspension of communication service made difficult to bind victims and supporters.
Victims is difficult to share with supporters to need help.
And Supporters is difficult to get the situation inside the disaster area.
It is critical issue to provide right support from supporters to victims.

On March 25, 2011, we founded "Pdrnet project: Post Disaster Recovery Internet Project" and provided satellite-based communication system to over 50 shelters in Sanriku coast area.
I address the importance of communication service continuity even collapsed ICT facilities in a disaster area based on knowledge from this project activities.
