Abstract: Aspects of the disclosure provide for a computer program product comprising computer executable instructions. The instructions are executable by a controller of a network device to cause the controller to analyze data transmitted by the network device via a network for a programmed amount of time, determine a data transmission pattern based on the analysis, determine, based on the transmission pattern, a volume of expected data transmission during a period of time, and determine whether to transmit additional data based on a relationship between the volume of expected data transmission during the period of time and a bandwidth allocation of the network device during the period of time.

Abstract: A wireless network with network-level channel hopping. A wireless network includes a wireless device. The wireless device includes a receiver, a data channel selector, and a transmitter. The receiver is configured to receive a beacon signal comprising a beacon sequence value. The data channel selector is configured to select, as a pseudorandom function of the beacon sequence value, a data channel on which to transmit in an interval following reception of the beacon signal. The transmitter is configured to transmit on the data channel selected by the channel selector.

Abstract: A system and method for enhanced channel hopping sequence is described. A pseudo random channel hopping sequence is redistributed using certain system specific parameters for separating adjacent transmission channels within a predetermined number of consecutive transmission channel numbers in the random channel hopping sequence to improve inter-channel interference between adjacent transmission channels.

Abstract: In examples, an electronic device comprises a transceiver and a processor coupled to the transceiver. The processor is configured to synchronize a clock of the electronic device to a clock of another electronic device using elapsed time indications in multiple packets received from the another electronic device via the transceiver. The processor is configured to transmit a packet via the transceiver using the synchronized clock of the electronic device.

Abstract: Embodiments of methods and systems for supporting coexistence of multiple technologies in a Power Line Communication (PLC) network are disclosed. A long coexistence preamble sequence may be transmitted by a device that has been forced to back off the PLC channel multiple times. The long coexistence sequence provides a way for the device to request channel access from devices on the channel using other technology. The device may transmit a data packet after transmitting the long coexistence preamble sequence. A network duty cycle time may also be defined as a maximum allowed duration for nodes of the same network to access the channel. When the network duty cycle time occurs, all nodes will back off the channel for a duty cycle extended inter frame space before transmitting again. The long coexistence preamble sequence and the network duty cycle time may be used together.
