Abstract

A method transmits data via an electric conductor of a current network. At least one first node and at least one second node are coupled to the electric conductor by a respective impedance-transparent coupling device. The method involves transmitting a carrier signal by the first node via the electric conductor, rectifying the transmitted carrier signal at the second node in order to supply energy to the second node, and modulating the transmitted carrier signal by the second node using a load modulation in order to transmit response data to the first node. The method is suitable in particular for low-maintenance and inexpensive sensor applications in current networks. An arrangement is used to transmit data via the electric conductor of a current network.
