A power grid network is provided that features a signal processor configured to: receive signaling containing information about digital content requested by one or more smart assets locally deployed in a smart asset infrastructure and communicatively coupled to the apparatus that is mounted in relation to a transformer configured in a grid network; and determine corresponding signaling containing information about the digital content requested by the one or more smart assets for providing back to a central location in the grid network for further processing, based upon the signaling received. The signal processor provides the corresponding signaling back to the central location in the grid network for further processing.
