Researchers tackle challenge of communicating with test flights using weaker frequencies
Using a wireless transmitter, you need to send 40 megabytes of data every single second over a distance of 100 miles. What's worse, your miniaturized, high-powered transmitters must convey all that data on some of the trickier frequencies of the electromagnetic spectrum. Their engineering work will help remake test-flight communications in the wake of a Federal Communications Commission auction of frequencies once used by the government.
