Abstract: A wireless device includes a wireless transceiver configured to transmit to and receive from nodes in a wireless sensor network (WSN) and control logic coupled to the first wireless transceiver. The wireless transceiver transmits a wireless packet to a node in the WSN based on the transmission coinciding with a break in transmissions for a second wireless network. Based on the wireless transceiver being configured to transmit the wireless packets utilizing time synchronized channel hopping, slot frames for packet transmissions in the WSN are time offset so as not to coincide with transmissions made on the second wireless network. Based on the wireless transceiver being configured to transmit the packets utilizing coordinated sampled listening, wake up sequence transmissions for the WSN are time offset so as not to coincide with the transmissions made on the second wireless network.

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).
