Abstract
A network architecture for underground communication using redundant interconnected communication systems utilizes an aboveground master control station to send a status request message to a belowground gateway. The gateway may then, in turn, broadcast a status request message to a plurality of communication hubs located throughout an underground region using each of a plurality of potentially available communication systems. In the event that one of the communication hubs fails to respond over the then-current communication system, the master control station may switch the current communication system being used to a truly available system.
