Donovan admits that drone-based LTE network isn't quite a reality yet, but the company has begun working towards that goal. Ma Bell has launched its national drone program's trial phase in San Francisco, where it demoed how it uses UAVs to inspect its cell towers. In addition to finding out how it can use drones to provide mobile internet, AT&T is also researching how they can tap into its LTE network to send and receive large amounts of data for commercial purposes. It will mostly likely take some time before you see signal-boosting flying machines at Coachella, though, so you'll probably still have to deal with failed Instagram uploads next year
