Abstract

Method and apparatus for communicating information using a structure 100 comprising; transmitting 610 in a structure a chirp which is associated with particular information and receiving 620 and identifying a partial chirp and associating it with a transmitted chirp. The chirp has an identifiable change in frequency varying over the time period associated with particular information being communicated. The structure may be a structural support and/or a passage for fluid. The structure may be a pipeline, tubular, drillstring or casing in an oil and/or gas structure. The information may be digital or communicated as words. The information may be media data, images, pictures, video or control data to control a down hole assembly. The transmitted signal may be an acoustic signal including ultrasonic signals. The information may be communicated in a medium in the structure such as liquid or gas.
