Abstract
A communication assembly is described that when placed around a string casing in a wellbore transmits data along a pipe string from the wellbore to, for example, the surface of the well. The assembly includes a high magnetic permeability substrate to eliminate signal loss to the casing string thereby enhancing the signal and improving data transmission.
