Abstract: A method of powerline communications in a powerline communications (PLC) network including a first PLC device and at least a second PLC device. The first PLC device transmits a data frame to the second node over a PLC channel. The second PLC device has a data buffer for storing received information. The second PLC device runs a flow control algorithm which determines a current congestion condition or a projected congestion condition of the data buffer based on at least one congestion parameter. The current congestion condition and projected congestion condition include nearly congested and fully congested. When the current or projected congestion condition is either nearly congested or fully congested, the second PLC device transmits a BUSY including frame over the PLC channel to at least the first PLC device. The first PLC device defers transmitting of any frames to the second PLC device for a congestion clearing wait time.

Abstract: A network includes a mobile network node (MNN) that includes a mobile node communications manager (MNCM) to facilitate wireless communications to a plurality of stationary network nodes (SNNs) in a wireless network via a wireless network protocol. The MNCM utilizes a multicast address received over the wireless network. The multicast address is assigned to a predetermined network time slot to communicate uplink data from the MNN to the SNNs. The MNN receives downlink data via a separate predetermined network address and time slot assigned to a given SNN.

Abstract: An ultrasonic communication circuit is disclosed. The circuit includes an ultrasonic transmitter arranged to transmit a training signal having a frequency to a remote transceiver over an ultrasonic communication channel. An ultrasonic receiver is arranged to receive information from the remote transceiver in response to the training signal. The ultrasonic transmitter is arranged to transmit a data signal to the remote transceiver. The data signal has a duty cycle determined by the information.

Abstract: In a powerline communications (PLC) network having a first node and at least a second node on a PLC channel utilizing a band including a plurality of tones, based on at least one channel quality indicator (CQI), the first node allocates for a tone map response payload only a single (1) power control bit for each of a plurality of subbands having two or more tones. The power control bit indicates a first power state or a second power state. The first node transmits a frame including the tone map response payload to the second node. The second node transmits a frame having boosted signal power for the tones in the subbands which have the first power state compared to a lower signal power for the tones in the subbands which have the second power state.
