Natural disasters have often made the headlines in
the past years. As a consequence, many actions have been
started by the public authorities to reduce the damages and the
number of casualties. In that objective, the French project
RATCOM aims at developing an alert system in case of coastal
tsunami. Its downstream components will propose reliable and
efficient communication systems to relay the alert. In parallel
to the integration of the existing technologies in the project
demonstrator, a survey analysis has been performed to identify
the communications technologies and networks which are in
preparation but not yet operational, and which will increase
the efficiency and quantity of individuals reachable by the
future population alert networks. Each of these technologies is
not sufficient by itself, but their combination will improve
drastically the efficiency of the alerting global system.
