IEEE is undertaking an effort to develop a standard for Broadband Power Lines. “Adding broadband capability to a local power distribution system is relatively straightforward. A computer-router combination and a coupler take the signal from an optical fiber cable as it enters a substation and imposes it on the electric current. The signal travels over the medium-voltage lines, with repeaters placed every 0.5 to 1 mile to keep the signal viable. A repeater/router near a residence or business extracts the signal off the medium voltage just before the transformer and injects it onto the low-voltage wiring on the other side of the transformer. The signal is now on all of the low voltage wiring within the structure and can be accessed at any outlet by plugging in a modem.” Sound easy enough – never mind that all previous efforts on BPL have had mixed results.
