Abstract: A data communication network that includes a wired network operably configured to transfer data at a rate between 100 Mbps to 500 Mbps over ordinary wire of the type used for low power electric distribution. This may be accomplished through use of two or more communication nodes each, respectively, including an Ethernet port electrically coupled to a first external power source at a lower voltage and including an AC/DC low pass filtering circuit and a LISN circuit configuration and communicatively coupled to one another through a wired connection, forming a wired network operably configured to exchange data between one another.
