Abstract

Data signals are communicated between a power line and a computer, wherein the power line provides power to the computer via a distribution transformer and the computer is in communication with a wireless communication path. A first data signal is communicated with the power line. A conversion is made between the first data signal and a second data signal capable of being communicated wirelessly. The second data signal is wirelessly communicated with the wireless communication path.
