METHODS OF COMMUNICATING OVER METALLIC CONDUCTORS HAVING MULTIPLE GROUNDS

摘要

METHODS OF COMMUNICATING OVER METALLIC CONDUCTORS HAVING MULTIPLE GROUNDS The invention provides methods of communication between two locations along a cable where the only metallic conductor available is grounded at numerous points along its length, which methods utilize a "distributed earth referenced carrier system" and wherein a first transceiver is electrically coupled to the metallic conductor at a first location and a second transceiver is electrically coupled to the metallic conductor at a second location.
