    Abstract: Various embodiments include methods of navigating a drone that may include determining whether a radio link quality trigger event associated with communications with the drone has occurred while the drone travels along a set route to a destination. The radio link quality trigger event may correspond to predetermined characteristics of radio link quality. The drone may be steered to follow a search maneuver for improving radio link quality in response to determining the radio link quality trigger event has occurred. The search maneuver may follow a preconfigured deviation pattern that is configured before determining whether the radio link quality trigger event has occurred and departs from the set route.

    Abstract: Various embodiments include methods for managing antennas on an aerial robotic vehicle used for wireless communications. A processor may receive position information identifying a location of the aerial robotic vehicle, determine whether to switch from using a first antenna to using a second antenna for active communications of the aerial robotic vehicle based on the position information, and switch active communications from using the first antenna to using the second antenna in response to determining that active communications of the aerial robotic vehicle should switch from using the first antenna to using the second antenna. The processor may make the determination using information from a database, which may correlate aerial robotic vehicle position to whether to use a particular one of the first and second antennas for active communications. The determination may also be based on a comparison of signal qualities obtained by both antennas.

    Abstract: Systems and methods for controlling a delay associated with paging a remote device. In one implementation, a paging device arranges page operations such that if one of two consecutive page scans performed by a remote device occurs during a response scan, the other page scan occurs during the transmission of a page. In another implementation, a device scanning for a page arranges page scans such that if one of two consecutive page scans occurs during a page response scan, the other page scan occurs during the transmission of a page. In another implementation, a device scanning for a page performs a series of sets of separate page scans, wherein the time interval between two of separate scans in a set is less than the time interval between adjacent sets. The page scans in a set are configured to ensure that one of them occurs during the transmission of a page.

    Abstract: Methods and apparatus for transmitting modulation parameters are disclosed. The apparatus and methods provide determination of when a particular modulation scheme is used by an access point. One or more modulation parameters associated with the particular modulation scheme and one or more timing values associated with the particular modulation scheme are then determined and transmitted using a portion of a broadcast channel transmitted by the access point.

    Abstract: The disclosure is directed to using motion to reduce unnecessary scans for local wireless networks. An aspect determines whether or not a motion state change event of a user device indicates a change from a moving motion state to a stationary motion state, and if the motion state change event indicates a change from a moving motion state to a stationary motion state, ignoring the motion state change event. An aspect of the disclosure is directed to using motion to reduce latency of scanning for local wireless networks. An aspect determines whether or not a user device is in motion, determines whether or not a periodic scan timer has expired and/or a received signal strength indicator (RSSI) is below a threshold, and if the user device is in motion and the periodic scan timer has expired or the RSSI is below the threshold, scanning for a local wireless network.
