  • Publication number: 20240069703
    Abstract: An electronic apparatus includes a display, a camera, a communication interface, a memory configured to store information, and a one or more processor configured to, based on the specific object being identified from an image obtained through the camera, identify a preset zone with respect to the identified specific object, based on a user being identified from the image obtained through the camera, identify whether the identified user is located within the preset zone, and based on a signal corresponding to a user interaction being received by the communication interface while the user is located in the preset zone, control the display to display a user interface screen corresponding to a type of the user interaction.

  • Patent number: 11469503
    Abstract: An antenna system including one or more a frequency responsive components (FRCs) may employ filters to one or more paths in the antenna system corresponding one or more radiating elements on those paths. The FRCs can block a signal from reaching the radiating elements effectively causing the radiating elements to become non-contributing to the antenna systems radiating pattern performance, and thus, maintain a consistent aperture value associated with the antenna system. In some cases, the FRCs may be configured to block a signal when the antenna system is operating at a particular frequency.

  • Patent number: 11189938
    Abstract: Low-profile end-fire antenna systems to provide additional throughput in areas of need with minimal structural and aesthetic impact. The system can include one or more low-profile end-fire antennas mounted to an exterior surface (e.g., a roof or parapet) of a building, parking deck, exiting cell tower, water tower, or other suitable structure. Additional electronics can be remotely mounted to maintain the low profile of the system. The system can be color-matched, or otherwise camouflaged, to maintain building aesthetics. The low-profile end-fire antenna can be mounted on a positioning stand to enable the elevation and/or azimuth of the system to be adjusted. The low profile of the antennas can reduce wind loading and enable the system to be mounted to existing structures without reinforcement, or other modification, to the structure. The orientation of the system relative to observers in many locations (e.g., on the ground) renders the system all but invisible.

  • Patent number: 10873885
    Abstract: A wireless communication system may support two types of networks, such as a 4th-Generation (4G) network and a 5th-Generation (5G) network. The 4G network is accessed through Long-Term Evolution (LTE) base stations. The 5G network is accessed through New Radio (NR) base stations. During idle mode, a communication device may scan 5G RF frequencies to determine whether a 5G signal is available and whether to display a 5G network symbol in the status bar of the device. The communication device is configured to detect conditions indicating whether a user of the device is likely viewing the device and/or the display of the device. If it is unlikely that the user is viewing the device or its screen, RF frequency scanning is paused to reduce power consumption and the currently displayed network symbol is maintained until RF frequency scanning is resumed.

  • Patent number: 10644810
    Abstract: An apparatus and method of propagating wireless signals through an impairment medium using a penetrator device within a wireless communication network is discussed herein. The apparatus and method includes transmitting a first radio frequency (RF) signal from a first point within the wireless communication network and receiving the first RF signal at a first unit of the penetrator device. The method further includes converting, by the first unit of the penetrator device, the RF signal into an optical signal and transmitting the optical signal from the first unit of the penetrator device to a second unit of the penetrator device through the impairment medium. The method also includes converting, by the second unit of the penetrator device, the optical signal into a second RF signal and transmitting, by the second unit of the penetrator device, the second RF signal to a second point within the wireless communication network.

  • Publication number: 20190165488
    Abstract: A dual circular polarization diversity scheme reduces the effects of atmospheric fading while providing a more efficient implementation and a more robust wireless link in a telecommunications backhaul network. A circular polarization diversity scheme alleviates issues with misalignment of transmitter and receiver polarization and thereby improves performance. By controlling the feed into the transmit antenna, the output can be a dual circular polarization scheme that simultaneously outputs left-hand circular and right-hand circular polarized radio signal.

  • Patent number: 10056963
    Abstract: Systems and methods for providing temporary cell coverage using lighter than air reflectors. The system can include a balloon or airship (e.g., a blimp) with a reflective lower surface. A ground-based source antenna can be aimed at the balloon to bounce cellular, or other communications, signals off the balloon and then back to the ground. The system can provide additional wireless coverage and bandwidth in remote locations and/or areas of high demand. The coverage area of the system can be adjusted by changing the shape of the bottom surface of the balloon. The coverage area of the system can also be adjusted by changing the height of the balloon above the source antenna. A dedicated source antenna and balloon can also serve as a microwave backhaul antenna system for a temporary cell site, using a balloon with a reflective surface shaped to collimate the radio link in a desired direction.

  • Patent number: 9660323
    Abstract: A combination antenna fixture is configured to accommodate adjustment of independent azimuths for each frequency band of operation of antennas of a mobile telephone network. The antennas may be mounted within a single radome or housing used to protect the antennas from environmental conditions. Each of the antennas may be coupled to a different movable mounting device within a radome, which may enable directing the azimuth for each antenna independently. By directing the azimuth independently for each antenna, the signal coverage area for each antenna may be customized to optimize coverage over a geographic area.
