Controlling drones via voice channels
The future is airborne. Drones may soon become the key to relieving the burden of traffic on our streets, optimizing deliveries, and improving the safety and efficiency of firefighting. But there are still a few hurdles to cross before the technology reaches the maturity required for large-scale commercial roll-out. In particular, a suitable communication system to control and determine their location remains a challenge. Drone communications must be stable and widely available, should cost as little as possible, and work reliably even when out of sight. Scientists at the Fraunhofer Institute for Telecommunications, Heinrich-Hertz-Institute, HHI in Berlin have found a solution: call a drone.
