Abstract
Techniques are disclosed by which RF mesh networks can identify utility distribution topologies by using power line communication combined with wireless networking to identify the mapping of transformers and other distribution equipment at a back office system server. At a specified time, an item of distribution equipment signals a unique identifier by introducing a phase shift in the electric power being delivered by that equipment. A meter node detects and decodes these temporal shifts to obtain an identifier of equipment supplying the power to it. Upon ascertaining this identification, the meter node sends an acknowledgment to thereby register with that equipment. The association of the particular customer's premises with the equipment is also sent to a back office system, to enable a map of the correspondence between meter and the equipment to be generated.
