摘要： Systems and methods for designing, using, and/or implementing beacon-enabled communications for variable payload transfers are described. In various embodiments, these systems and methods may be applicable to power line communications (PLC). For example, a method may include implementing a superframe having a plurality of beacon slots, a plurality of intermediate slots following the beacon slots, and a poll-based Contention Free Period (CFP) slot following the intermediate slots. Each of the beacon slots and each of the intermediate slots may correspond to a respective one of a plurality of frequency subbands, and the poll-based CFP slot may correspond to a combination of the plurality of frequency subbands. The method may also include receiving a poll request over a first of the plurality of frequency subbands during the poll-based CFP slot, and then transmitting a data packet over a second of the plurality of frequency subbands during the poll-based CFP slot.

摘要： Systems and methods for designing, using, and/or implementing hybrid communication networks are described. In various embodiments, these systems and methods may be applicable to power line communications (PLC). For example, one or more of the techniques disclosed herein may include methods to coordinate medium-to-low voltage (MV-LV) and low-to-low voltage (LV-LV) PLC networks when the MV-LV network operates in a frequency subband mode and the LV-LV network operates in wideband mode (i.e., hybrid communications). In some cases, MV routers and LV routers may have different profiles. For instance, MV-LV communications may be performed using MAC superframe structures, and first-level LV to lower-level LV communications may take place using a beacon mode. Lower layer LV nodes may communicate using non-beacon modes. Also, initial scanning procedures may encourage first-to-second-level LV device communications rather than MV-to-first-level LV connections.

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.
