Use in Disaster Response
See also: Cascading failureMost mobile telephone networks operate close to capacity during normal times, and large spikes in call volumes caused by widespread emergencies often overload the systems when they are needed most. Examples reported in the media where this has occurred include the September 11 attacks, the 2006 Hawaii earthquake, the 2003 Northeast blackouts, Hurricane Katrina, the 2007 Minnesota bridge collapse, the 2010 Chile earthquake and the Dawson College shooting. Reporters and journalists have also been using satellite phones to communicate and report on events in war zones such as Iraq.
Terrestrial cell antennas and networks can be damaged by natural disasters. Satellite telephony can avoid this problem and be useful during natural disasters. Satellite phone networks themselves are prone to congestion as satellites and spot beams cover a large area with relatively few voice channels.

Famous quotes containing the words disaster and/or response:
“The appropriation of radical thinking by lazy, self-obsessed hippies is a public relations disaster that could cost the earth.”
—Ben Elton (b. 1959)
“The truth is that literature, particularly fiction, is not the pure medium we sometimes assume it to be. Response to it is affected by things other than its own intrinsic quality; by a curiosity or lack of it about the people it deals with, their outlook, their way of life.”
—Vance Palmer (1885–1959)
