Required EMS channels via satellite communications after major disaster
2012
We calculate the number of channels necessary for satellite communications to support the early-stage telemedicine after major disasters. Medical data acquired from the Great Hanshin-Awaji Earthquake (Kobe Earthquake) is used for the calculations of Erlang B formula The minimum 29 channel shall be necessary to cover nationwide after major disaster. In case of big tsunami such as East Japan earthquake, we shall consider a smaller EIRP equipment on the ground, with charging by the solar cells. So the big G/T antenna of the spacecraft shall be required and designed to support disaster communication after a big tsunami attack.
