Abstract: An integrated circuit for use in a wireless management system with a primary node and secondary nodes includes: a wireless transceiver; and a wireless management controller included with or coupled to the wireless transceiver. The wireless management controller is configured to: identify a first secondary node of the secondary nodes in communication with the primary node; identify a second secondary node of the secondary nodes not in communication with the primary node; and enable the first secondary node to operate as a proxy node that repeats downlink messages to or uplink messages from the second secondary node.

Abstract: At least some aspects of the present disclosure provide for a method of data transmission, performed by a wireless device. In some examples, the method includes receiving a localization tone having a first value. The method further includes inserting the localization tone into a data packet at an application layer of a communication protocol stack, the localization tone preceding data of a payload of the data packet and having a last bit immediately preceding a first bit of the data of the payload. The method further includes generating a modified localization tone estimating an effect of processing on the localization tone, wherein the modified localization tone is generated and configured to have the first value after undergoing processing. The method further includes replacing the localization tone in the data packet with the modified localization tone. The method further includes transmitting the data packet.

Abstract: Apparatus (and related methods) for a power line communication network include a processor configured to receive beacons over a communication interface. The processor determines a link quality indicator (LQI) for each received beacon and ignores the beacons for at most a predetermined maximum number of beacon receptions when each LQI is below a threshold. The processor responds to a received beacon if the LQI for such received beacon exceeds the threshold or if a predetermined maximum number of beacons have been received with LQIs below the threshold.

Abstract: A communication circuit for communications between a controller and a subsystem with a monitored electrical component is described. The communication circuit includes network formation circuitry configured to establish a wireless network between a primary wireless node adapted to be coupled to the controller and a secondary wireless node coupled to the subsystem. The communication circuit also includes data transfer circuitry configured to perform data transfers between the primary wireless node and the secondary wireless node. The communication circuit further includes data integrity circuitry configured to: generate a hash for data received by the communication circuit; and verify the hash before the data transfer circuitry performs a data transfer of the data between the primary wireless node and the secondary wireless node.

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.

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: An energy efficient task scheduler for use with a processor that provides multiple reduced energy use modes. In one embodiment, a system for executing tasks includes a processor and a task scheduler. The processor provides a plurality of different reduced energy use modes. The task scheduler is executable by the processor to schedule execution a plurality of sleep tasks. Each of the sleep tasks corresponds to a different one of the reduced energy use modes. The task scheduler is executable by the processor to execute each of the sleep tasks, and as part of the execution of the sleep task to: place the processor in the reduced energy use mode corresponding to the sleep task, and exit the corresponding reduced energy use mode at suspension of the sleep task.
