Systems and methods for providing broadband internet access to mobile platforms such as vehicles, aircraft, and portable devices, using a network of one or more entities such as drones/unmanned aerial vehicles (UAVs). In one embodiment, the drone communication system comprises an antenna sub-system, a radio sub-system and a data switching sub-system. The mobile platforms comprise antenna and radio sub-systems to communicate with the drones, detect changes in the mobile platforms azimuth and elevation changes, and adjust the mobile platform's antenna beam to compensate for the orientation changes to optimally point toward the drones. The exemplary mobile platform further comprises methods to detect the need for handoff to a different drone and to carry out the handoff.
