  • Patent number: 10764858
    Abstract: Methods and apparatus for processing and using signals transmitted by a device, e.g., a low cost beacon transmitter device, to facilitate making location determinations with regard to the transmitting device and/or making a decision of when or how to use location information generated based on received signals are described. In accordance with some features the processing performed on the received signal strength measurements is based on whether or not the device from which the signals are received is in motion. The size of a sample period used as a processing window when determining device location is based, in some embodiments, on the rate of motion. When and/or how to use location determinations are performed is also based on motion in some embodiments. Machine learning updates of location determination parameters, based on received signals, are disabled when the signals are from devices determined to be in motion.

  • Patent number: 10715408
    Abstract: Methods and apparatus for controlling monitoring operations performed by various devices, e.g., access points, in a communications network and for using information obtained by the devices which perform the monitoring are described. The methods are well suited for use in a system with a variety of access points, e.g., wireless and/or wired access points, which can be used to obtain access to the Internet or another network. An access point, which has been configured to monitor in accordance with received monitoring configuration information, e.g. on a per access point interface basis, captures packets, stores captured packets, and monitors to detect communications failures corresponding to communications devices using said access point. In response to detecting a communications failure, the access point generates, an event failure notification indicating the type of detected failure and sends the event failure notification to the network monitoring node along with corresponding captured packets.

  • Patent number: 10581863
    Abstract: A first set of access rules is received from an access configuration service. The first set of access rules specifies addresses of devices authorized for a first user. A second set of access rules is received from the access configuration service. The second set of the access rules specifies addresses of devices authorized for a second user. At a wireless access point, a network packet associated with the first user is received. The first set of access rules is applied to filter the network packet.

  • Patent number: 10536894
    Abstract: Methods and apparatus relating to use of actual and/or virtual beacons are described. Virtual beacons are virtual in that an actual beacon need not be transmitted but a rather a virtual beacon transmitter at a desired location maybe considered to transmit virtual beacons. In some embodiments a set of beacon transmitter information for one or more beacons is supplied to devices in a communications system. The beacon transmitter information indicates transmission power and location of actual and virtual beacon transmitters as well as information to be communicated by virtual beacons. Devices with access to beacon information can determine based on the location of a wireless terminal whether the wireless terminal is within coverage area of a virtual beacon and report reception of the virtual beacon to the wireless terminal or a component of the wireless terminal which acts upon receiving an indication of beacon reception.

  • Patent number: 10219166
    Abstract: Methods and apparatus for using beacon signals are described. One or more sectorized base stations are used in some embodiments to transmit beacon signals into zones, e.g., each zone being at least partially covered by one or more beacon signals. Use of sectorized base stations allows a single base station, e.g., a Bluetooth or other base station capable of transmitting beacon signals, to cover a number of different zones avoiding the need for multiple different beacon transmitters at different locations to establish different beacon coverage areas. Sectorization of a Bluetooth base station and the ability to remotely or locally configure the base station allows for great flexibility to use beacon signals in stores or other locations without the need for numerous individual battery powered beacon transmitters at floor or display level.

  • Patent number: 9967803
    Abstract: Methods and apparatus relating to use of actual and/or virtual beacons are described. Virtual beacons are virtual in that an actual beacon need not be transmitted but a rather a virtual beacon transmitter at a desired location may be considered to transmit virtual beacons. Beacon transmitter information indicates transmission power and location of actual and virtual beacon transmitters as well as information to be communicated by virtual beacons and is dynamically updated based on device movement, a schedule and/or the locations of devices in a group. Virtual personal beacons, virtual group beacons and virtual scheduled beacons are supported. A virtual personal beacon transmitter location is updated as the location of a device corresponding to the person moves. Reception of a virtual beacon is reported in a message sent to a wireless terminal or a component of the wireless terminal which acts upon receiving an indication of beacon reception.

  • Patent number: 9832082
    Abstract: A wireless access point system includes a processor configured to tap event data and process the event data using a plurality of event filters. Each event filter of the plurality of event filters applies event criteria to detect one or more types of events. The wireless access point system includes a memory configured to store the tapped event data. The wireless access point system includes a communication interface configured to report a report of a detected event type. At least a portion of the report is correlated to analyze a performance of a wireless network.
