  • Publication number: 20190190583
    Abstract: The present disclosure describes apparatuses and methods of performance-based antenna selection for user devices. In some aspects, a user device includes a transceiver having a first receiver, as well as second and third receivers. The transceiver is coupled to a first antenna to enable communication via the first antenna and the second receiver is coupled to the second antenna to enable reception via the second antenna. The third receiver is coupled to a third antenna to enable monitoring of performance of the third antenna. Based on a comparison of respective performance of the first antenna and the third antenna, the first antenna or third antenna is coupled the transceiver to enable subsequent communication. By monitoring and comparing respective performance of the antennas before antenna switching is implemented, a better-performing antenna of the two antennas can be selected for coupling to the transceiver without impacting communication performance.

  • Patent number: 10122081
    Abstract: A method and system for detecting whether the position of a user's hand gripping a mobile communication device chassis affects an external antenna is provided. A sectioned metal band about a periphery of a mobile communication device has a radiating antenna in at least one metal section. The radiating antenna section is bounded on both sides by electrically floating metal sections. Each of the electrically floating metal sections is bounded on the side distal from the antenna section by a ground metal section. Each metal section separated from an adjacent metal section by an insulating gap. Embodiments measure a differential capacitance between the antenna section and the floating metal section and measure a single and capacitance between the floating metal section and the grounded section to determine whether a user's hand is bridging one or more of the insulating gaps.

  • Publication number: 20170160397
    Abstract: Implementations relate to systems and methods for location assistance using devices (104) in a personal area network (PAN). In one scenario, a user may use two separate location-enabled devices, such as a wearable personal device (102) and a cellular telephone device (104). In cases, one of those devices may have reached a higher or farther-developed state in terms of generating or storing location information (108) for the user's current position, as compared to the opposite device. This can take place, for instance, when the first (e.g. wearable) device (102) is first turned on. The two devices use platforms and techniques to exchange location information and carry out GPS or other operations to furnish the device that is lagging in position processing progress with assistance which will speed up or otherwise enhance the position fix for that device.
