  • Patent number: 10680665
    Abstract: Systems and method are provided to facilitate predictive mitigation of noise. A vehicle may measure noise floor levels and transmit a noise floor signal to a noise signal aggregator. Based on the noise signal, the noise signal aggregator may update a noise floor map database. The noise floor map database may associate a plurality of geographic locations with a plurality of noise floor levels. Accordingly, the noise signal aggregator may update a noise floor level in the noise floor map database that corresponds to the location associated with the transmitted noise signal. The noise floor map database may then be queried to retrieve noise floor levels for locations further along a route traversed by a vehicle such that the vehicle may predictively tune one or more antennas to mitigate interference associated with the noise floor.

  • Patent number: 9960874
    Abstract: Embodiments of the present invention provide techniques for managing interference across multiple transceivers in an access point in a network environment. A wireless networking system can include various access points. These access points may each include multiple transceivers. However, with multiple transceivers in close proximity, signals transmitted by one transceiver may interfere with another transceiver through crosstalk, adjacent channel interference, or other form of interference. Each access point may include an interference manager which can use an interference model to modify a signal transmitted by one transceiver to be used to cancel corresponding interference caused in a second transceiver. Interference can be modeled prior to deployment and/or at deployment using a series of test signals transmitted by one transceiver while the corresponding interference is monitored on a second transceiver.

  • Patent number: 9406998
    Abstract: A distributed multiband antenna intended for radio devices, and methods for designing manufacturing the same. In one embodiment, a planar inverted-F antenna (PIFA) configured to operate in a high-frequency band, and a matched monopole configured to operate in a low-frequency band, are used within a handheld mobile device (e.g., cellular telephone). The two antennas are placed on substantially opposing regions of the portable device. The use of a separate low-frequency antenna element facilitates frequency-specific antenna matching, and therefore improves the overall performance of the multiband antenna. The use of high-band PIFA reduces antenna volume, and enables a smaller device housing structure while also reducing signal losses in the high frequency band. These attributes also advantageously facilitate compliance with specific absorption rate (SAR) tests; e.g., in the immediate proximity of hand and head “phantoms” as mandated under CTIA regulations.

In a modulation state transition phase, the first and third signals delivered by the first and third generators are at a different frequency from the carrier frequency of the signals delivered by the second generator. The resonance frequency of the first and third antenna arrangements is also adapted in the transition phase.

  • Patent number: 8988224
    Abstract: In one embodiment the present invention includes an RFID gaming token with a ferrite core. When the RFID gaming tokens are stacked, the ferrite cores steer the flux field from the excitation antenna through the center of the annular antennas in each token. The resulting flux field increases the efficiency of the energy transfer from the excitation antenna to the passive tags. This increased efficiency also improves the data transfer to and from the passive tags. This increased efficiency allows for reading RFID gaming tokens at a higher stack height (or at a better error rate for a given stack height) as compared to existing air core gaming tokens.

  • Patent number: 8588795
    Abstract: A scheduling method in a distributed antenna system is provided. Each of a plurality of Mobile Stations (MSs), respectively corresponding to each subchannel, are classified as a Single Transmission (ST) MS or a Cooperative Transmission (CT) MS according to a CT criterion. An MS with a maximum channel capacity is selected from among the classified MSs. Resources are allocated to a corresponding subchannel when the selected MS is the ST MS, and resources are allocated using a CT scheduling technique when the selected MS is the CT MS. The classifying, selecting and allocating steps are repeated until allocation of resources is completed.

  • Publication number: 20130187817
    Abstract: An antenna system includes a low-band antenna configured for low-band frequencies and a high-band antenna configured for high-band frequencies. The low-band antenna is configured so that high-band frequencies have a high impedance while the high-band antenna is configured so that low-band frequencies have a high impedance. A transmission line can be used to couple both antennas together and the transmission line can be used to add phase delay to the impedance of the low-band and high-band antennas so that the corresponding frequencies that the antennas are not configured for are shifted toward an infinite impedance point on a Smith chart.

  • Patent number: 8432283
    Abstract: In one embodiment the present invention includes an RFID gaming token with a ferrite core. When the RFID gaming tokens are stacked, the ferrite cores steer the flux field from the excitation antenna through the center of the annular antennas in each token. The resulting flux field increases the efficiency of the energy transfer from the excitation antenna to the passive tags. This increased efficiency also improves the data transfer to and from the passive tags. This increased efficiency allows for reading RFID gaming tokens at a higher stack height (or at a better error rate for a given stack height) as compared to existing air core gaming tokens.

    Abstract: An antenna system has multiple antenna elements, and multiple connection points allowing multiple users to connect to the antenna system. Each connection point is connected to each of the antenna elements through respective amplitude control circuitry, with the beam shape for each user being controlled by the amplitude control circuitry in the paths between that user's connection point and the antenna elements. The beam shapes for the different users are then independently controllable.

  • Patent number: 8395507
    Abstract: In one embodiment the present invention includes a radio frequency identification (RFID) system with a shorting loop. The shorting loop at least partially surrounds the antenna. The shorting loop distorts the electromagnetic field generated by the antenna to improve the definition of the border of the read region of the antenna. In this manner, the RFID system provides more accurate discrimination between RFID tags inside the read region versus RFID tags outside the read region (i.e., improves the accuracy of determining that a particular RFID tag is inside the read region).

  • Patent number: 8185162
    Abstract: An electrically tilted antenna system with polarization diversity has a dual polarized, tilt adjustable antenna (32). The antenna (32) has dipoles (34, 36) of two orthogonal polarizations associated with independently adjustable electrical tilt angles. The tilt angles are implemented by relative delays between corporate feed input or output signals, the delays being introduced by an antenna tilt assembly (54). Two signal feeders (F21, F22) associated with different antenna polarizations connect the antenna tilt assembly (54) to a base station filter assembly (50): the base station filter assembly 50 routes transmit signals from base stations (BS21, BS22) to different antenna polarizations via respective feeders (F21, F22) and the antenna tilt assembly (54). This assembly also divides receive signals from feeders (F21, F22) between both base stations (BS21, BS22).
