1. 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 including a base data concentrator node, comprising:

  • said first node sending a physical layer (PHY) data frame, including a Cyclic Redundancy Check (CRC) information, on said PLC channel comprising a preamble, a PHY header, a MAC header and a MAC payload, wherein said MAC header includes a Cyclic Redundancy Check (CRC) field (MH-CRC field) in addition to the data frame (CRC) information;

    said second node receiving said data frame, said second node;

    parsing said MAC header to reach said MH-CRC field; and

    performing CRC verification using said MH-CRC field to verify said MAC header, and wherein if said CRC verification is successful, (i) parsing another portion of said MAC header to identify a destination address of said data frame and (ii) determining whether said data frame is intended for said second node from said destination address.
