Abstract: A method of powerline communications (PLC) includes compiling a data frame for physical layer (PHY) by a first communications device at a first communications node on a powerline of a PLC network. The data frame includes a single tone PHY header portion and a data payload portion in a set of tones including at least one tone having a frequency different from a frequency of the single tone. The PHY header portion includes tone mask identification information identifying the set of tones. The first communications device transmits the data frame over the powerline to a second communications device at a second communications node on the powerline.

Abstract: Systems and methods for implementing symbol-level repetition coding in power line communications (PLC) are described. In some embodiments, these systems and methods may provide reliable communication in severe channel environments of PLC networks, at least in part, by changing the forward error correction (FEC) used by various devices operating within current PLC systems. For example, a method may include receiving a PLC signal and applying convolutional encoding to the received signal, the convolutional encoding producing an encoded signal. The method may also include performing a subcarrier modulation operation upon the encoded signal, the subcarrier modulation operation producing a modulated signal. The method may further include applying symbol-level repetition coding to the modulated signal, the symbol-level repetition coding producing a repetitious signal. In some cases, one or more distinct repetition patterns may be applied to different symbols or portions thereof. The repetitious signal may then be transmitted over a power line.

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.

Abstract: A method of powerline communications between a plurality of nodes on a powerline communications (PLC) channel including a first node and a second node. At least one communication quality measure is determined for the PLC channel. Based on the communication quality measure, a preamble of a data frame is dynamically switched between a reference preamble having a reference symbol length including a reference number of syncP symbols and a reference number of syncM symbols and at least a first extended preamble having an extended symbol length that is greater than (>) the reference symbol length. The data frame is then transmitted on the PLC channel.

Abstract: Communication devices, such as base nodes and modems, that comply with two or more different standards operate on a shared communication channel. To avoid mutual interference, a base node operating under a first standard reserves time using a contention free period designation. The base node allows devices operating under a second standard to communicate during the reserved time by not assigning the contention free period to another device operating under the first standard. Alternatively, a device using the first standard may avoid interference from transmissions generated under the second standard by modifying data packets prior to transmission. A prefix corresponding to a preamble in the second standard is added to the beginning of the data packet created under the first standard. Devices operating under the second standard observe the prefix and recognize that the channel is active. The second-standard devices backoff from transmission thereby minimizing interference.
