Abstract

An operational monitoring system for use in communications, and a method thereof, for operational, systems or integrity management of pipeline infrastructures which operates by broadcasting wireless signals through gas distribution networks and analyzing the traversed signals to assess the operational, systems or integrity of the natural gas pipelines. The operational monitoring system includes a transmitter located at a first location arranged to transmit a wireless signal through natural gas contained within a pipeline infrastructure; a receiver located at a second location structured to receive the wireless signal transmitted through the natural gas contained within the pipeline infrastructure; and a device to analyze the received wireless signal indications of operational changes in the natural gas pipeline infrastructure.
