    Abstract: A powerline network may comprise powerline communication (PLC) devices of a first class of PLC devices that are incompatible with PLC devices of a second class of PLC devices. This can result in interference between communications of the first and the second classes of PLC devices. A dual mode PLC device that is compatible with the first and the second classes of PLC devices can be implemented for coexistence with both classes of PLC devices. The dual mode PLC device can determine whether the powerline network comprises a combination of PLC devices of the first and the second classes of PLC devices. One of a plurality of packet headers that is compatible with both the classes of PLC devices can be selected for transmission in response to determining that the powerline network comprises a combination of PLC devices of the first and the second classes of PLC devices.

    Abstract: A method for communicating among nodes in a network includes determining, by a transmitter, a first frequency band and at least a second frequency band to be used for communicating data packets, wherein a maximum allowable power spectral density in the first frequency band is greater than a maximum allowable power spectral density in the second frequency band. The method also includes adjusting power spectral density for a first group of frequencies in the first frequency band such that the adjusted power spectral density of the first group does not exceed the maximum allowable power spectral density of the first frequency band and a quantization noise introduced by the transmitter is less than a threshold value for a signal transmitted in the second frequency band. The method further includes modulating at least a portion of a data packet transmitted by the transmitter to at least a first receiver in accordance with the adjusted power spectral density.

    Abstract: A method of operating in a network in which a plurality of stations communicate over a shared medium (e.g., using a carrier sense multiple access (CSMA) service). The stations contend for access to the shared medium using a contention procedure that relies on a priority level, wherein transmissions with a lower priority level have a reduced chance of gaining access to the shared medium during a contention process. Selected stations are given the capability of temporarily promoting the priority level of transmissions they are attempting to make. The priority level is increased during an interval to reduce the chance that other stations gain access to the shared medium during that interval, and the priority level is restored to its normal level following the interval.

    Abstract: Systems and methods for dynamic allocation of network bandwidth. In some examples, a guaranteed interval period, including a guaranteed interval start time and guaranteed interval end time, can be identified based upon policy. Network stations can then identify first interval start times and first interval end times different than the guaranteed start times and guaranteed end time provided by policy. An access network can thereby provide a first interval start time and a first interval end time to stations within the access network. An in-home network can determine an in-home interval period based upon the first interval start time and first interval end time.
