Abstract: Technology is disclosed herein for a method of operating a UAV as an access point for communication with one or more ground controllers and/or one or more other UAVs. In an implementation, a UAV establishes a connection, including an uplink and downlink, between the UAV and a ground controller such that the UAV is an access point with respect to the ground controller. The connection is established in accordance with a wireless protocol that divides the RF spectrum into bands of resource units with respect to uplinks and downlinks between access points and non-access points. The UAV identifies a single resource unit (RU) to support uplink traffic and instructs the ground controller to transmit uplink traffic on the single resource unit. The UAV receives uplink traffic from the ground controller on the single resource unit.

Abstract: Technology is disclosed herein for dynamically selecting a communication channel for communication between an unmanned aerial vehicle and an access point. In an implementation, an unmanned aerial vehicle selects a current channel for communicating with an access point by performing a scan of the communication channels and, for each channel, generating a score based on performance metrics acquired during the scan. The communication channels are sorted into an ordered list according to the scores of the communication channels. The vehicle selects the first channel of the ordered list to be the current channel and periodically evaluates the channel performance against a performance threshold. Upon determining that the performance of the current channel is below the performance threshold, the vehicle evaluates the second channel from the ordered list.

Abstract: Technology for operating an unmanned aerial vehicle (UAV) communication system is disclosed herein that allows an UAV communication system to transition between modulation modes. In various implementations, a wireless radio of the UAV communication system operates in a dynamic modulation mode such that the wireless radio dynamically adjusts the modulation rate of a signal within a range of possible modulation rates. The wireless radio transitions to a fixed modulation mode, based at least on a current modulation rate of the signal reaching a low end of the range of possible modulation rates. When in the fixed modulation mode, the wireless radio holds the modulation rate at the low end of the range of possible modulation rates. The wireless radio returns to the dynamic modulation mode based on the quality of the signal.
