  • Patent number: 11128055
    Abstract: Systems and devices relating to antennas and antenna systems. A horizontal omnidirectional antenna has two dipoles with each dipole being in a V-configuration such that the arms of the dipole define an angle. The two dipoles are arranged so that the angles defined by each of the dipoles face and open toward each other. The horizontal omnidirectional antenna can be configured to operate with specific frequency bands. By nesting two instances of this antenna, with one configured for high band frequencies and one configured for low band frequencies, a dualband omnidirectional antenna can be obtained. The resulting antenna is physically compact and can be used in small MIMO systems along with vertical omnidirectional antennas.

  • Patent number: 11129069
    Abstract: Methods and systems are provided for delaying a dynamic connection modification of a user device connection. A first frequency band is determined to have a greater sector power ratio (SPR) than a second frequency band. The first frequency band is determined to have a loading volume above a threshold. Based at least in part on the first frequency band having the greater SPR and the first frequency band having the loading volume above the threshold, a dynamic change of a user device connection to the first frequency band for access to a first wireless telecommunications network is delayed.

  • Patent number: 11047702
    Abstract: An electronic device may be provided with control circuitry for locating lost items. The control circuitry may determine where an item is located and may use the display or other output device to guide a user to the item. The display may display a visual guide such as an arrow, a sphere, a circle, a compass, or other visual aid that points the user in the direction of the item. The control circuitry may change the size or other characteristic of the visual aid on the display as the distance between the electronic device and the object changes. The control circuitry may change the location of the visual aid on the display as the orientation of the electronic device relative to the object changes. The display may overlay the visual aid onto live images of the user's surroundings as they are captured by a camera.

  • Patent number: 11041936
    Abstract: An autonomously reconfigurable surface for adaptive antenna nulling includes a lattice of electrically conductive elements (which may be embodied as crossed metallic dipoles) mounted on a thin and preferably conformal surface and aperiodically loaded with reactance tuning elements and/or RF (and typically high power) sensing circuits. Additional elements mounted on this surface include analog to digital convertors (ADCs), digital to analog convertors (DACs), and microcontroller(s). The analog outputs of the DACs are networked to reactance tuning elements via, for example, a network of thin copper traces. The analog inputs of the ADCs are networked to the RF sensing circuits via a network, for example, of thin copper traces. The digital outputs of ADCs and the digital inputs of DACs are networked to microcontroller(s) via a network, for example, of thin copper traces.

  • Patent number: 11025377
    Abstract: A fixed wireless access system is implemented using orthogonal time frequency space multiplexing (OTFS). Data transmissions to/from different devices share transmission resources using—delay Doppler multiplexing, time-frequency multiplexing, multiplexing at stream and/or layer level, and angular multiplexing. Time-frequency multiplexing is achieved by dividing the time-frequency plan into subgrids, with the subsampled time frequency grid being used to carry the OTFS data. Antenna implementations include a hemispherical antenna with multiple antenna elements arranged in an array to achieve multiplexing.
