摘要： A method of powerline communications including a first node and at least a second node on a powerline communications (PLC) channel in a PLC network. The first node sends a physical layer (PHY) data frame on the PLC channel including a preamble, a PHY header, a MAC header and a MAC payload. The MAC header includes a Cyclic Redundancy Check (CRC) field (MH-CRC field). The second node receives the data frame, parses the MAC header to reach the MH-CRC field, and performs CRC verification using the MH-CRC field to verify the MAC header. If the CRC verification is successful, (i) the second node parses another portion of the MAC header to identify a destination address of the data frame and (ii) to determine whether the data frame is intended for the second node from the destination address.

摘要： Phase detection between service nodes in a as “PRIME” (“PoweRline Intelligent Metering Evolution”) communications network, in which the service nodes are connected to one phase of a three-phase power distribution network. A service node joining a sub-network receives packet data units from other service nodes in the sub-network, including those that can potentially serve as a switch node to which the joining service node can register. The joining service node measures an elapsed time between a zero crossing of the AC power waveform at its phase and the start of a frame in the received packet data units. This elapsed time is compared with a similar zero crossing gap communicated by other service nodes in the packet data units, to identify the relative phases to which the two service nodes are connected.
