  • Patent number: 10348379
    Abstract: Systems, devices and methods for providing communications between a beamforming access point and a non-beamforming device are provided. The access point determines a beamforming steering matrix from a feedback matrix received from a beamforming device located at a given position, and controls the communication interface to beam form using the beamforming steering matrix to communicate with a non-beamforming device located at the given position. A beamforming device may receive an identifier and characteristics of a non-beamforming device in wireless communication therewith, determine, from the characteristics, a feedback matrix of the non-beamforming device, and transmit the feedback matrix to an access point.

  • Patent number: 10142797
    Abstract: System and methods of deploying location tracking tags are provided. A device receives: identifiers of a plurality of tags fixed at locations in a physical space, each of the plurality of tags configured to broadcast: a respective identifier; and identifiers of respective neighboring tags of each of the plurality of tags. The device further receives respective locations of a subset of the plurality of tags. The device determines remaining respective locations of the plurality of tags not in the subset from: the respective locations of the plurality of tags in the subset and the identifiers of respective neighboring tags of each of the plurality of tags. The device can populate a memory and/or a database with the remaining respective locations of the plurality of tags not in the subset for use by a location tracking server.

  • Patent number: 10078950
    Abstract: Remotely configurable location tracking tags are provided. A tag broadcasts a tag identifier according to configuration data stored at a memory. The tag receives new configuration data and an associated tag identifier. When the associated tag identifier matches the tag identifier: the tag updates the configuration data stored at the memory with the new configuration data and changes the broadcast of the tag identifier in accordance with the new configuration data. When the associated tag identifier does not match the tag identifier: the tag modifies the broadcast of the tag identifier to include the new configuration data and the associated tag identifier, the broadcast continuing to occur according to the configuration data.

  • Patent number: 9848383
    Abstract: A Bluetooth low energy (BLE) beacon in a BLE network is electrically powered by a battery, broadcasts messages, and listens for a network communication indicative of whether a mobile device is present in a venue. A beacon controller controls the beacon to periodically broadcast the messages and to periodically listen for the network communication during an active mode of operation, to not broadcast the messages to conserve power from the battery and to listen for the network communication during a power save mode of operation, and to switch from the power save mode to the active mode when the network communication received during the power save mode indicates that a mobile device is present in the venue.
