Abstract
A method of communicating over a power line communications system is provided. Data is received into a power line communication system (PLCS). The downstream data may be transmitted along a medium voltage power line in one or more multicast packets to a plurality of devices. Along pathways for transmitting the downstream data toward one or more user devices, multicast packets may be repeated or reformed. In some embodiments, a device may package the data in a unicast packet for transmission along a portion of the pathway. Along the pathways for upstream transmission data from one or more user devices, unicast packets may be transmitted. Wireless links, low voltage power line links, or other wired links are established for delivering multicast packets to and unicast packets from user devices located among the subscribers' premises.
