Abstract

An emergency warning network including a base station for broadcasting a warning signal and a first, earth-orbiting satellite for receiving the warning signal and rebroadcasting such to extend the range of communications of the base station. A first substation receives the warning signal and broadcasts a first forwarding signal in response thereto to a first portable receiver. A second substation also receives the warning signal and broadcasts a second forwarding signal in response thereto via a second, earth-orbiting satellite to a first branch station. The first branch station broadcasts a third forwarding signal in response to the second forwarding signal to a second portable receiver. A second branch station also receives the second forwarding signal via the second, earth-orbiting satellite and broadcasts a fourth forwarding signal to a third portable receiver.

Dependent claims

An emergency warning system, comprising:

a base station for broadcasting a warning signal;
a first, earth-orbiting satellite for receiving said warning signal and rebroadcasting such so as to extend the range of communications of said base station;
a first substation for receiving said warning signal from said first, earth-orbiting satellite and for broadcasting a first forwarding signal in response thereto;
a first portable receiver for receiving said first forwarding signal from said first substation;
a second substation for receiving said warning signal from said first, earth-orbiting satellite and for broadcasting a second forwarding signal in response thereto;
a second, earth-orbiting satellite for receiving said second forwarding signal and rebroadcasting such so as to extend the range of communications of said second substation;
a first branch station for receiving said second forwarding signal from said second, earth-orbiting satellite and for broadcasting a third forwarding signal in response thereto;
a second portable receiver for receiving said third forwarding signal from said first branch station;
a second branch station for receiving said second forwarding signal from said second, earth-orbiting satellite and for broadcasting a fourth forwarding signal;
and,
a third portable receiver for receiving said fourth forwarding signal from said second branch station.
