Abstract: A hub involving a large geographical area (e.g., states) communicates with other hubs and with spokes involving smaller geographical areas within the hub area. Selective hubs and spokes form a network in which they communicate messages to one another to enhance a public safety activity. A dynamic response group formed from individuals in the hub and spokes may also be included in the network. The communication between the hubs and spokes may be voluntary and may occur through Radix switches which identify the sender and the recipient, process the message and pass the processed message to the recipient. Each group or individual may be invited, or ask to be invited, into the network. Each group or individual may leave the network voluntarily or at the network's request. The groups and individuals act in the network on a coordinated basis to enhance the public safety activity.
