Abstract: Line cycle adaptation periods having variable duration are disclosed. A powerline cycle may be segmented into a plurality of line cycle adaptation periods having variable duration based upon signal-to-noise (SNR) characteristics measured at various times throughout the powerline cycle. The line cycle adaptation periods may include at least two periods with unequal durations. Each line cycle adaptation period may be associated with one or more tone maps defining physical layer transmission properties to be used by a second device for transmissions occurring during the line cycle adaptation period.

Abstract: An adaptive filter bank can be implemented on a PLC device to dynamically adapt to variations in notching requirements and the performance of the PLC medium. The PLC device can apply filter coefficients to one or more filter elements of the adaptive filter bank to generate one or more notched subcarriers in the PLC band. A performance measurement of one or more subcarriers in the PLC band can be determined and evaluated against corresponding performance measurement thresholds. For a given notched subcarrier, if the performance measurement of the corresponding subcarriers is not in accordance with the performance measurement threshold, updated filter coefficients for the filter element configured to generate the notched subcarrier can be determined based, at least in part, on the performance measurement of the one or more subcarriers. The filter coefficients of the filter element can then be updated using the updated filter coefficients.

Abstract: A powerline communication diversity coupling mechanism may implement a transformer coupling unit. The transformer coupling unit can receive a communication signal to be coupled to a plurality of powerline communication channels for transmission in a powerline communication network. The transformer coupling unit can split the communication signal into a plurality of communication signals for transmission. The transformer coupling unit can couple each of the plurality of the communication signals to a corresponding one of a plurality of the powerline communication channels for transmission in the powerline communication network. Also, the transformer coupling unit can receive a plurality of communication signals on each of a plurality of powerline communication channels. The transformer coupling unit can combine the plurality of the communication signals into a communication signal. The transformer coupling unit may then couple the communication signal to an analog front end and other processing units for processing the communication signal.

Abstract: A feature-capable device that supports channel reuse and is part of a local network can determine whether to reuse or share a communication channel with a neighbor network when the local network and/or the neighbor network include at least one legacy device that does not support adaptive channel reuse. The feature-capable device can determine channel performance measurements associated with each legacy device in the local network and/or in the neighbor network. The feature-capable device can compare the channel performance measurements against corresponding performance thresholds. The local network and the neighbor network can reuse the channel if the channel performance measurements associated with each of the legacy devices meet the corresponding performance thresholds. The local network and the neighbor network can share the channel if the channel performance measurements of at least one of the legacy devices does not meet the corresponding performance thresholds.

Abstract: A hybrid bridge can implement functionality for selectively populating its bridge tables based on preferred transmission routes to influence other network devices to transmit frames based on the preferred transmission routes. The hybrid bridge determines a preferred transmission route for communicating with each network device in the hybrid communication network. For each of the network devices, it is determined whether the hybrid bridge is part of the preferred transmission route associated with the network device. Depending on whether the hybrid bridge is part of the preferred transmission route to the network device and/or whether a network interface of the hybrid bridge is a transmit or a receive interface on the preferred transmission route, a local bridge table or a remote bridge table of the network interface can be populated with at least the address of a destination network device.

Abstract: A hybrid device can be configured to use WLAN communication links for bridging network traffic between any pair of network devices in a hybrid communication network, irrespective of whether the bridged network devices support WLAN communication. The hybrid device receives a first data frame in a first frame format for transmission to a destination device. The hybrid device accesses its hybrid forwarding tables and identifies a transmit interface from which to transmit the first data frame for transmission to the destination device. If the transmit interface is a WLAN interface, WLAN forwarding tables associated with the WLAN transmit interface are accessed to identify a receiving WLAN device to which the first data frame should be transmitted. The WLAN transmit interface converts the first data frame into a second data frame in a WLAN frame format and transmits the second data frame to the receiving WLAN device.
