A highly fault tolerant system for datagram communication of information in the form of a message packet employs a distributed network of transmitter/receivers 'transceivers', which interact with 'bridge transceivers' which are transceivers connected to a wired network, and wired nodes each having a unique identification ("ID") number. An initiating unit, which may be a transceiver, bridge transceiver or wired node, creates a message packet having an ID of an intended destination unit. If initiated from a transceiver, the message packet finds its way to a wired network by broadcasting the message packet to local transceivers. The transceivers determine valid message packets which have not expired, not been received before and were transmitted without errors. If the message packet is valid and the transceiver ID does not match its internal ID, the transceiver broadcasts the valid message packet to other local transceivers. The transceivers which receive the message packet repeat the process. The message then finds its way to a bridge transceiver connected to a wired network. A 'NODE LOC' is embedded in the message packet identifying a closest wired node. The message is routed through the wired network to the wired node and then transmitted as described above to a destination unit by radio signals.
