A steerable antenna, of a UAV, is used to optimize connectivity to a wireless network, such as to radio access network (RAN) of a cellular wireless network. In one implementation, the altitude of a UAV may be used to determine a direction in which to point the antenna of the UAV. In some implementations, additional factors, such as the travel direction of the UAV and/or the known location of base stations associated with the wireless cellular network, may alternatively or additionally be used to determine the direction of the antenna.
