Magic Box, which is given free to Sprint customers who qualify, has proven to be a very useful product to get coverage where it’s needed, according to Günther Ottendorfer, COO of technology at Sprint. Then Sprint came up with another idea: use it for certain applications to provide coverage from the air.  Sprint formed a partnership with drone manufacturer CyPhy Works. They modified the power supply and created a light version of the Magic Box product and mounted it on the bottom of a drone.
