Abstract: An emulated wireless access point (AP) at a first PMC device (PMC1) establishes a first tunneled direct link setup (TDLS) session between a first station module (STA1) incorporated into the PMC1 and a second station module (STA2) incorporated into a second PMC device (PMC2). Following establishment of the TDLS session, the wireless AP is allowed to sleep; and most infrastructure management duties are handled by the STA1 during the session. PMC device battery charge may be conserved as a result. The emulated wireless AP may also establish a second TDLS link to a third station module (STA3) incorporated into a third PMC device (PMC3). The STA1 may then bridge data traffic flow between the STA2 and the STA3. Such bridging operation may enable communication between two PMC devices otherwise unable to decode data received from the other.

Abstract: A method for communicating in a wireless sensor network (WSN) is described. Using control logic, a first wireless transceiver is caused to transmit a wireless packet to a node in a wireless sensor network. The control logic bases its causing on a transmission coinciding with a break in transmission for a second wireless network, such that the transmission from the first wireless transceiver does not coincide with transmissions made on the second wireless network. Time synchronized channel hopping (TSCH) slot frames for wireless packet transmission in the wireless sensor network are caused to be time offset if the first wireless transceiver is utilizing TSCH. Wake up sequence transmissions for the wireless sensor network are caused to be time offset if the first wireless transceiver is utilizing coordinated sampled listening (CSL).

Abstract: In accordance with disclosed embodiments, a first power line communication (PLC) device connected to a PLC network includes channel control logic that assigns a first channel of the PLC network for transmission on a power line of PLC data packets between the first PLC device and a second PLC device connected to the PLC network and assigns a second channel of the PLC network for transmission on the power line of PLC data packets between the first PLC device and the third PLC device connected to the PLC network. The PLC device includes a transceiver that receives and transmits PLC data packets on the PLC network and which operates as a bridge device that communicates on both the first and second channels to pass PLC data packets between the second PLC device and the third PLC device.

Abstract: A power line communication (PLC) network includes a plurality of PLC devices. One such PLC device may include a transmitter power control system that determines a minimum level of transmission power for sufficiently communicating a plurality of data packets from the PLC device over the PLC network to a first destination PLC device on the PLC network by executing a training sequence over the PLC network via an electrical power distribution system. The transmitter power control system applies this minimum level of transmission power to transmit the data packets to the first destination PLC device.

Abstract: A system and method for arbitrating channel access in a wireless device including co-located network transceivers are disclosed herein. A wireless device includes a first wireless transceiver and a second wireless transceiver. The first transceiver is configured for operation with a first wireless network. The second transceiver is configured for operation with a second wireless network. The wireless device further includes logic that determines which of the first and second transceivers is enabled to transmit at a given time. The logic causes the first transceiver to transmit a notification signal indicating a time period during which the second transceiver of the wireless device will perform a first wireless transaction, and during which, based on receiving the notification signal, a different wireless device performs a second wireless transaction via the second wireless network without transmitting a notification signal.
