    摘要： 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.

    摘要： Methods of operating in a network in which a plurality of stations communicate over a shared medium and contend for access during a priority resolution period. At least some of the stations use a first CSMA network protocol having certain characteristics (e.g., some transmissions have a format that includes a start of frame delimiter (SOF), a payload, and an end of frame delimiter (EOF), wherein the SOF and EOF each contain sufficient information to permit a station receiving only one of the SOF and EOF to determine the start of a priority resolution period). And at least some stations use a second network protocol capable of coexisting with the first protocol, so that stations may communicate using either the first or second protocol. The second protocol may have various characteristics configured to achieve coexistence with the first protocol (e.g., transmissions that have a format that includes an SOF but not an EOF).

    摘要： A method of operating in a network in which a plurality of stations communicate over a shared medium. The method comprises transmitting a group of bits from a transmitting station to a receiving station, wherein the group of bits comprises information bits and error checking bits, and communicating additional bits from the transmitting station to the receiving station without transmitting the additional bits. Communicating the additional bits comprises, at the transmitting station, deriving the error checking bits from the additional bits using an error checking process; and at the receiving station, using the same or a related error checking process to process candidate bits known to the receiving station, and comparing the output of the error checking process to the error checking bits received from the transmitting station to determine if the candidate bits correspond to the additional bits.

    摘要： 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.
