Google and Facebook arent the only ones trying to beam down connectivity from the sky: DARPA, the US Defense Departments advanced research agency, is trying to turn drones into hotspots for high-speed wireless networks, and it recently completed an initial testing and development phase on the program working toward that goal. The major developments were in the creation of steerable antennas and efficient radio amplifiers for the hotspots. DARPA also created a housing for the hotspots, which will eventually be mounted on drones that have traditionally been used for surveillance. We’re pleased with the technical achievements we’ve seen so far.
