Study on the Application of Stratosphere Emergency Communication according to Communication Problems during Wenchuan Earthquake

Emergency communication plays a crucial role in dealing with unexpected events.The communication system in epicenter regions was attacked severely by 5·12 Wenchuan earthquake.Rescuing survivals got more difficult due to the disable communication system.Stratosphere emergency communication equipment is involved in this paper in order to retrofit the disable communication system quickly.Once again,the design details of the system are presented,including:(1) both emergency command communication equipment and cellular mobile communication base station are carried in high altitude aeronautical platforms(HAAPs);(2) HAAPs are set up by airship;(3) emergency command communication equipment is used for commanding and cellular mobile communication base station is for public communication.Analysis demonstrates this emergency communication system shows the features of fast deploy capability low cost and large capacity.
