ABSTRACT:
A power line based communication system includes a power line termination module, a plurality of power line gateways, and a plurality of power line nodes. The power line termination module manages data for local area networks within the power line based communication system. The plurality of power line gateways is arranged in sets of power line gateways, wherein each set of power line gateways constitutes a local area network. Each of the plurality of power line nodes is operably coupled to the power line termination module via a high-speed communication path. In addition, each power line node is operably coupled to set of power line gateways, i.e., to a local area network, via power lines of a local transformer. Each of the power line nodes receives data for its respective LAN from the power line termination module and provides the data to the power line gateways of its LAN via the power lines of the local transformer. Virtual local area networks are enabled between the power line termination module and the power line gateways.
