Abstract: Embodiments of methods for adaptive sub-band point-to-point communication are presented. In one embodiment a method includes performing functions using a power line communication (PLC) transmitter device. The method may include receiving a first data packet having a first adaptive sub-band information set, the first sub-band information set comprising information from a PLC transmitter. The method may also include extracting the first sub-band information set from the first data packet. Additionally, the method may include analyzing the first sub-band information set to determine a transmitter sub-band hopping pattern. The method may further include setting a corresponding receiver sub-band hopping pattern synchronized to the sub-band hopping patter used by the PLC transmitter and hopping to a subsequent sub-band as defined by the receiver sub-band hopping pattern.

Abstract: An algorithm for the promotion of terminal nodes to switch nodes in a PLC network reduces overall network overhead and collisions, while ensuring the appropriate selection of a switch node and minimizing the number of levels in a PLC network. It also ensures that the terminal nodes with appropriate signal-to-noise ratios (SNRs) are promoted. It is desirable to have a network with fewer levels. The disclosed approach favors the nodes that are closer to the DC to promote them as switch nodes. This is achieved by waiting for a smaller number of PNPDUs for a node that is closer to the DC in comparison to a node that is farther away from the DC.

Abstract: A device may be coupled to a time slot based communication system and receive a timing beacon packet that is broadcast in a time slot of the communication system at a periodic rate, in which the network uses a time slotted channel hopping protocol of sequential frames each having a plurality of time slots. The device may synchronize its time base to the timing beacon. The device may calculate a sleep time corresponding to a number of time slots until a next time slot that is scheduled for use by the device and then place the device in a sleep mode. The device may be awakened after the sleep time and operate during the next time slot. The device may repeat the process of calculating a sleep time, going into sleep mode, and waking for operation after the sleep time in order to reduce power consumption.

Abstract: 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.
