Abstract

A system for providing situational awareness outside a temporary incident area network includes a prioritized connection module for connecting a mesh network at the incident area to one of a plurality of available communications channels, with the selection based not only on the availability of a communications channel but also on the associated expense, speed, reliability or bandwidth, so that high bandwidth traffic such as video and pictures can be reliably sent from the incident area to a location outside of the incident area. In one embodiment switching to a satellite phone network bypasses problems with terrestrial networks such as cell phone networks and landlines which may be down.

Claims

1. A method for intercommunication between one or more entities of two different talk groups of a mesh network in art incident area regardless of the type of communications devices or frequencies used by the entities, comprising;

enabling communication between the two different talk groups using a central command controller that converts traffic between the one or more entities of two different talk groups to a universal protocol and a common frequency;

causing the one or more entities of two different talk groups to set up an ad hoc temporary incident area, network and establishing a communications interoperability solution with one or more newly-arriving entities, whereby interoperability is established between all of the entities at the incident regardless of communication device protocol or frequency compatibility and wherein the talk groups eliminate interference between communications interoperability solutions of the mesh network.
