    Abstract: A system includes a UAV with at least three rotors, a flight controller on the UAV, and a pistol-grip-style transmitter to receive operator input for controlling the UAV. The transmitter includes (1) a speed trigger for controlling a linear speed of the UAV, (2) a steering wheel for performing left or right turns by the UAV, (3) an altitude slider for controlling a flying altitude of the UAV, and (4) a communication interface to send control signals indicating relative positions of the speed trigger, the steering wheel, and the altitude slider. The flight controller includes a processor to receive, from the transmitter, the control signals indicating the relative positions of the speed trigger, the steering wheel, and the altitude slider. The processor adjusts, in response to the control signals, a rotational speed of each rotor independently to implement the operator input for forward-facing flight.

    Abstract: A system may determine, using first location data, that a client device is located in an interior of a premises in which multiple wireless network access points (APs) are deployed in a wireless network; identify, using second location data, locations of the client device within the interior; obtain, for the locations, a dataset including wireless network signal strength values corresponding to signal coverage areas associated with the wireless network APs; generate, using the dataset, a wireless network mapping corresponding to a layout of the interior; evaluate, against connectivity rules, the wireless network mapping with respect to overlapping signal coverage areas, the connectivity rules defining operations for connecting the client device to the wireless network as a function of the locations; and apply at least one of the operations to the client device at a current location relative to a preceding location and/or a succeeding location of the client device.

    Abstract: A device may establish a first connection to a first radio access network (RAN) associated with a first radio access technology (RAT). The device may register to receive a call service via the first RAN. The device may receive the call service via the first connection. The device may establish a second connection to a second RAN associated with a second RAT that is different from the first RAT. The device may register to receive the call service via the second RAN. The device may compare a first signal quality metric, associated with the first connection, and a second signal quality metric associated with the second connection. The device may cause the call service to be transferred from the first connection to the second connection, based on comparing the first signal quality metric and the second signal quality metric, without causing an interruption to the call service.
