Facebook built a helicopter-drone to provide wireless internet to disaster areas

Facebook announced what it’s calling “Tether-tenna technology,” essentially a small, unmanned helicopter that will provide Wi-Fi access to crisis zones when existing Wi-Fi towers are down or damaged. The helicopter-drone, which is roughly the size of a Volkswagen Beetle, is literally tethered to a fiber line and a power source on the ground, which enables the chopper to stay airborne for days at a time. (Facebook says its goal is to keep it up for weeks or months.)

The Tether-tenna technology is still in early testing, which means it isn’t being deployed to actual disaster areas just yet, said Yael Maguire, head of Facebook’s connectivity lab. Maguire — whose team also built Facebook’s internet-beaming drone, Aquila, and is laying hundreds of miles of fiber cable in Africa to increase access to the internet there — estimates that one helicopter could connect “in the neighborhood of thousands to tens of thousands of people.” The Aquila drone hasn’t been deployed yet either; the aircraft was damaged after it crashed upon landing during a test flight last summer.
