New drone antenna expands Wi-Fi range for disaster-struck areas

 The team says these figures represent a marked improvement on existing solutions and could lead to new forms of wireless communication.

"This technology would be very useful in disaster scenarios when the cell towers are down and there's no communication infrastructure," says Yan Wan, Assistant Professor of Electrical Engineering at UNT and leader of the research project.

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.
