Researchers from the University of North Texas (UNT) Denton have demonstrated an unmanned aerial vehicle (UAV) capable of supplying Wi-Fi to disaster-struck areas with a range of up to 5 km (3.1 miles).

Where typical Wi-Fi antennas have a range of around 100 m (328 ft), Wan and her team were able to extend this by developing a directional antenna. The antenna rotates to automatically align with a target, serving to better maintain a strong communications link and prevent signal disruption, but there is still some way to go before it's real-world implementation.

"In order to enable the information dissemination between the rescue teams and control centers, we need to have a structure available to make this happen," Wan says. "And this is what we're trying to provide." The damage to the communications infrastructure that often accompanies the destruction of buildings in storm-ravaged areas makes it difficult for response teams to communicate efficiently, and to keep disaster victims informed.
