  • Method for data transmission via an electric distribution system and transmission system for carrying out the method
    Patent number: 4800363
    Abstract: A method and system for the transmission of data in an electric distribution system between a central controller coupled to a medium-voltage distribution line and at least one terminal coupled to a low-voltage wherein, the transmission of data within the medium-voltage distribution line takes place at a first carrier frequency (f.sub.1), and the data at the first carrier frequency is transposed to data at a lower second carrier frequency (f.sub.21, f.sub.22) for transmission from the medium-voltage distribution line to the low-voltage distribution line by means of a transponder. Due to this transposing of carrier frequencies, the system can be optimized with respect to the different channel properties of the two communication channels.
