Although not all of these technologies did immediately save lives in this regard a number of them exhibited considerable potential for the future and hence there is a need to include them in future contingency plans. However a need for change in the modes and patterns of technology deployment to maximize their leverage has also become very clear. In the immediate aftermath of a catastrophic disruption communication channels break down and must be reestablished as rapidly as possible so that emergencies may be reported and first response team efforts coordinated in the field. Cell towers are typically not equipped with sufficient emergency power backup capacities and backup generators of long-distance switches do not tolerate flooding. As a result both mobile phone and long-distance phone terrestrial communication suffered an almost complete disruption in Katrina s wake. Over 60 of networks were still down 3 weeks after the event 1 . In comparison satellite communications remained quantitatively operational and were utilized within minutes of the disaster by FEMA the National Guard and the Red Cross as well as by state and local first responders utility workers and people in search of relatives. More than 20 000 Globalstar Iridium and Mobile Satellite Ventures satellite phones and terminals were deployed in the affected region within 2 days after the event. .
