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 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: 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.

Abstract: Apparatus, systems, and methods disclosed herein operate to provide wireless communication between personal mobile communication (PMC) devices. 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).

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).
