Patent ID: 8665087

Claim:
For use on an ad hoc temporary incident area network a number of traditional transceivers; a standalone add-on module including PTT control and audio in and out connectivity from the associated transceiver to said standalone add-on module for providing transceiver interoperability, said standalone add-on module adapted to be connected to one of said transceivers to automatically convert audio information available from the transceiver to which said module is coupled to a common format and frequency assigned to equipment operating on the temporary incident area network, thus to assure that all receivers on said ad hoc temporary incident network can intercommunicate; a sensor coupled to said module for coupling sensor data to said module; a circuit at said module for uploading sensor data to said network; and, a downloading unit at a node for downloading the sensor data carried by said network and for displaying said sensor data at said node, thus to reliably provide sensor data by using said network.
