    摘要： A wireless device that includes an access point (AP) scanner, a transceiver, and a controller coupled to the AP scanner and transceiver. The AP scanner is configured to scan wireless network channels utilized by one or more APs to transmit data packets, probe responses, and beacons. The transceiver is configured to transmit one or more probe requests to the one or more APs and receive one or more probe responses and beacons from the one or more APs. The controller is configured to determine a proximate geographic position of the wireless device based on signal strength of the one or more probe responses and beacons received from the one or more APs. The controller also dynamically adapts a parameter utilized in determining the proximate geographic position of the wireless device.

    摘要： 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.

    摘要： 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).

    摘要： A network includes a parent node and at least one child node configured to communicate with the parent node via a wireless network protocol. The parent node includes a broadcast coordinator to transmit a broadcast message from the parent node to the child node at predetermined time intervals according to the wireless network protocol. A scheduler generates a scheduling packet that is communicated in the broadcast message. The scheduling packet includes a data field to instruct each child node to activate and receive data communicated from the parent node in a prescribed time slot following the broadcast message that is defined by the scheduling packet.
