    Abstract: A powerline communication (PLC) network analyzer can join a PLC network by authenticating and associating with a central coordinator of the PLC network. The network analyzer can receive an encryption key from the central coordinator and dissociate from the PLC network. The network analyzer can capture and decrypt network traffic from the PLC network while remaining dissociated. The network analyzer can also create one or more virtual stations for the PLC network. The virtual stations can join the PLC network through the central coordinator and generate network traffic for the PLC network.

    Abstract: This disclosure provides several mechanisms for adapting transmit power spectral density (PSD). A communications device may adapt the power spectrum utilized at the transmitter based, at least in part, on the channel conditions or PSD constraints associated with the communications medium between the transmitter and a receiver device. Additionally, the transmit PSD may be adapted based, at least in part, on a total power capability associated with a transmitter. Power is allocated to improve throughput and utilization of the communications channel. A transmission profile may be selected based, at least in part, on the notch depth. The transmission profile may be associated with symbol timing parameters. The communications device may maintain a plurality of selectable pulse shapes that are optimized for different notch depths.

    Abstract: Powerline communication (PLC) networks allow devices within a home, automobile, or other systems to communicate over existing wired powerline infrastructure. Active PLC networks can affect devices sharing the powerline infrastructure as well as wireless devices through radiated noise emissions. Provided in the present disclosure are exemplary techniques for reducing noise emissions and promoting coexistence of multiple PLC systems and/or non-PLC (e.g., wireless) systems.

    Abstract: A network device may include a plug that couples with a socket to couple the network device to a PLC network. A position of the plug may be interchanged when the plug is coupled with the socket. In one example, the network device may determine a coupling orientation of the plug that indicates the position of the plug with respect to the socket. The plug includes a first plug terminal, a second plug terminal, a first ground plug terminal, and a second ground plug terminal. The network device may select a signal polarity for the plug based, at least in part, on the coupling orientation. The signal polarity indicates over which of the plug terminals data is to be transmitted for communication over the PLC network.
