Abstract: A first device and a second device may coordinate to determine a power level or frequency in a first frequency band that is associated with causing intermodulation (IM) interference at a second frequency band (e.g., a protected frequency band). An IM interference detection test may include at least a first test signal transmitted from the first device to the second device via a communications medium. The second device may detect for the presence of IM interference associated with the first test signal. A series of test signals may be used to identify power levels and/or frequencies that cause IM interference in the second frequency band. A transmitting device may improve performance by increasing power for particular frequencies up to a power level that maintains IM interference below a threshold level.

Abstract: Methods, systems, and devices are described for minimizing mutual interference between networks that implement different protocols. In one embodiment, a first network device of a first network may exchange coexistence information with a second network device of a second network to determine whether to share resources or reduce transmit power based, at least in part, on the interference detected at the first network device from a transmission of the second network device. In one embodiment, both the first and the second network devices may independently and iteratively reduce their respective transmit power to minimize interference between the interfering networks. The first network device may reduce its transmit power based on an interference of the second network device and vice versa. In another embodiment, the network device with a lower priority may minimize its transmit power to reduce interference with the network device with a higher priority.

Abstract: Testing procedures and associated messaging can be performed via powerline communication (PLC) medium. A first device can test a second device using management messages via the PLC medium. For example, the first device may transmit a test setup request message including at least one test parameter to the second device via the PLC medium. The first device may conduct a test of the second device in accordance with the at least one test parameter. The first device may determine a first performance metric associated with the test. The first performance metric can describe at least one of a PLC interface of the second device and the PLC medium between the first device and the second device. Test results can be translated to a common format for comparison to traditional tests which may be based on Ethernet performance metrics.

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.
