  • Patent number: 9401874
    Abstract: Access point functionality of a network device may be disabled, resulting in a coverage hole in a communication network and affecting performance of a client device. Various techniques can be implemented for detecting and minimizing coverage holes. In one embodiment, the network device can selectively establish a communication link with the client device depending on whether the client device is in a coverage hole and depending on whether the client device can detect another access point in the communication network. In some embodiments, the client device can determine that it is in a coverage hole in response to detecting a reserved SSID and can accordingly notify a central coordinator of the communication network. In some embodiments, the central coordinator can identify the network device (with disabled access point functionality) that can eliminate the coverage hole and can cause the network device to enable its access point functionality.

  • Publication number: 20160044697
    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).
