Abstract

In one aspect, the invention comprises a system comprising: a master data clock source; one or more transponders; and a plurality of remote power line transceivers; wherein all of said plurality of transceivers are connected to a common alternating current power distribution grid; and wherein each of said plurality of transceivers has a location is operable to monitor a voltage waveform of a power line prevailing at said location. In another aspect, the invention comprises a system comprising: transponders and remote power line transceivers each connected to a common alternating current power distribution grid each operable to monitor the voltage waveform of the power line prevailing at its own location, and generate selectable frequencies from said local power line waveform of a frequency of p/q times the frequency of said power line where p and q are positive integers greater than or equal to 1.

Claims

1. A system comprising:
