Abstract

Methods and systems for communicating information between a narrowband circuit and a broadband circuit for conserving bandwidth while monitoring gas turbine combustion dynamics are provided. The method includes receiving a stream of data through the narrowband circuit, splitting the stream of data into a plurality of data packets, and transmitting each of the data packets to a predetermined list of sockets through the broadband circuit. The system includes a narrowband network segment communicatively coupled to a broadband network segment, and a data network split/relay device communicatively coupled to the broadband network segment programmed to receive a stream of data from a server communicatively coupled to the narrowband segment.
