Claim:
1. A method of wireless distributed energy metering, the method comprising: determining a voltage reference sampling clock at a distribution hub; generating one or more digitized voltage samples from an alternating current (AC) line under measurement coupled to the AC line by a voltage sensing device; encoding a voltage reference data frame comprising the one or more digitized voltage samples; and broadcasting the voltage reference data frame over radio frequencies (RF) to one or more wireless metering units each coupled to an AC load circuit of the AC line where a current sample clock of each of the wireless energy metering units is synchronized to the voltage reference sampling clock of the distribution hub, and the one or more voltage samples from the distribution hub and one or more current samples obtained by one or more current sensing devices at the one or more wireless metering units are utilized in calculating energy parameters sampled by the wireless energy metering units from the respective AC load circuit.
