Abstract
A tool for communicating data between multiple locations downhole includes a tool body, a first antenna including at least one electrode disposed within a wall and electrically insulated from the tool body, and an electronic circuit configured to generate an encoded electrical signal and propagate the encoded signal through the electrode into a medium surrounding the tool, and a second antenna coupled to the tool body, and an electronic circuit configured to receive an electrical signal induced by the second antenna.
