Unmanned aerial vehicle drive testing and mapping of carrier signals is disclosed. An example method may include determining that an unmanned aerial vehicle is travelling on a flight route at an altitude for determination of network performance of a cellular network. The method may further include determining, using an antenna, signal diagnostics of the cellular network during travel of the unmanned aerial vehicle on the flight route. The method may conclude with transmitting the signal diagnostics of the cellular network to a service provider.

Unmanned aerial vehicle drive testing and mapping of carrier signals

Dynamic shielding of cellular signals for an antenna of an unmanned aerial vehicle is disclosed. An example method may include receiving a navigation route for an unmanned aerial vehicle to execute during flight of the unmanned aerial vehicle and determining an orientation of a radio signal shield for an antenna of the unmanned aerial vehicle using ground level signal propagation information of radio signals for a network and the navigation route, wherein the radio signal shield prevents the radio signals from being received by the antenna from directions based on the orientation. The method may further include adjusting the radio signal shield using the orientation and communicating with a cellular base station of the network using the antenna.

Maintaining network connectivity of aerial devices during unmanned flight is facilitated. An example method may include providing, to an access point of a radio access network (RAN) during flight of the unmanned aerial vehicle (UAV) on a flight route, channel allocation instructions for connecting the UAV to the radio access network via communication channels. The method may further include detecting an interference event associated with a portion of the flight route of the UAV during the flight. The method may further include adjusting, during the flight, the channel allocation instructions in response to detecting the interference event. The method may further include providing the adjusted channel allocation instructions to an access point of the radio access network during the flight.

Maintaining network connectivity of aerial devices during unmanned flight

Altitude based device management is provided herein. A method can comprise transmitting, by a mobile device comprising a processor, a signaling message to a network device of a wireless network. The signaling message can comprise first data indicating a device type of the mobile device and second data indicating a distance measurement of the mobile device with respect to a reference point. The method can also comprise implementing, by the mobile device, a first instruction related to a power setting and a second instruction related to an operating parameter. The first instruction and the second instruction can be received from the network device and can be based on the device type of the mobile device and the distance measurement of the mobile device.

Altitude based device management in a wireless communications system

Example methods and systems are disclosed to facilitate detection and identification of devices connected to a cellular network and that are causing interference to the cellular network. An example method may include receiving, by a serving base station of the device, a first set of information associated with data communications of a device utilizing a cellular network. The method may further include determining the device is an interfering device based on the first set of information associated with the data communication substantially corresponding with an interfering device profile, and in response tracking the device. During the tracking of the device, a second set of information associated with the data communications from the device may be obtained, and an interfering device type of the device may be determined based on the second set of information. An action may be performed on the interfering device based on its interfering device type.

Interfering device identification

Example methods, apparatuses, systems, and articles of manufacture (e.g., physical storage media) to facilitate interference mitigation of aerial devices on a radio access network are disclosed. An example method includes receiving, by a processor from a base station of the radio access network, an indication of an interference event associated with the base station, and determining, by the processor, a set of unmanned aerial vehicles (UAVs) associated with the base station during flight of the set, where the interference event is at least partially attributed to each UAV of the set. The method further includes selecting, by the processor, a UAV among the set based on a respective traffic profile associated with each UAV of the set, and providing, by the processor, an instruction to the UAV to cause an adjustment of an operation of the UAV to reduce an interference impact of the UAV on the base station.
