  • Patent number: 8873660
    Abstract: A method and apparatus controls diversity reception in a wireless communication device. By determining a value based on a number of active set pilot signals received from a set of base stations, the wireless communication device dynamically enables or disables diversity reception. Diversity reception can be controlled by adjusting a diversity threshold based on the determined value. A channel quality indicator of a channel is measured and compared against the adjusted diversity threshold. The diversity reception mode is then enabled or disabled based on the comparison. For example, if the number of active pilot signals is above a predetermined value, indicating “good” coverage, the diversity threshold is decreased. The measured channel quality indicator is compared against the adjusted threshold, and diversity reception is enabled when the channel quality indicator is less than the decreased diversity threshold.

  • Publication number: 20140024328
    Abstract: A portable unit with an endfire antenna and operating at 60 GHz makes an optimum communication channel with an endfire antenna in an array of antennas distributed over the area of a ceiling. The portable unit is pointed towards the ceiling and the system controlling the ceiling units selects and adjusts the positioning of an endfire antenna mounted on a 3-D adjustable rotatable unit. Several transceivers can be mounted together, offset from one another, to provide a wide coverage in both azimuth direction and elevation direction. These units can be rigidly mounted as an array in a ceiling apparatus. The system controlling the ceiling array selects one of the transceivers in one of the units to make the optimum communication channel to the portable unit. The system includes the integration of power management features by switching between Wi-Fi in favor of the 60 GHz channel.

  • Patent number: 8577314
    Abstract: Methods and systems for dynamic range detection and positioning utilizing leaky wave antennas (LWAs) are disclosed and may include configuring one or more LWAs to enable communication of signals in a particular direction. RF signals that are reflected from an object may be received via the LWAs, and a location of the object may be determined based on the received reflected RF signals. The velocity of the object may be determined based on a Doppler shift associated with the received reflected RF signals. A frequency chirped signal may be transmitted by the LWAs to determine a location of the object. A resonant frequency of the LWAs may be configured utilizing micro-electro-mechanical systems (MEMS) deflection. LWAs may be situated along a plurality of axes in the wireless device. The LWAs may include microstrip or coplanar waveguides, where a cavity height is dependent on spacing between conductive lines in the waveguides.
