The Aquila drone isn’t the one aerial web challenge Fb deserted within the final 12 months. The Tether-tenna, a small helicopter drone that might briefly exchange mobile service in emergency conditions, was discontinued just a few months after being proven off on the F8 developer convention in Could of 2017, the corporate has confirmed to The Verge.
“Tether-tenna was a proof of idea challenge we had been evaluating after we mentioned it at F8 in early 2017,” a spokesperson for Fb stated. “It wasn’t one thing we pursued additional as we selected to focus our efforts on continued improvement and development of our Terragraph, millimeter-wave, and HAPS [high altitude platform station] applications. We have interaction in a variety of proof of idea initiatives like this one as they’re nice studying automobiles for our connectivity groups.”
Yael Maguire, who runs Fb’s Connectivity Lab, described the idea at F8 final 12 months in entrance of a video of the Tether-tenna prototype that confirmed it take off, hover, and land. The concept was that the helicopter would be capable to tether to fiber and energy strains in locations the place mobile infrastructure was broken, fly skyward, and broadcast a sign from tons of of toes up within the air.
Fb supplied the antenna for Tether-tenna, however the helicopter drone that the corporate confirmed within the video at F8 was principally constructed by a small startup known as Everfly, which had been spun out of a analysis innovation agency known as Otherlab, based on a Recode report from final 12 months.
“What Fb informed you is appropriate, they did nothing extra with [Tether-tenna] following what they confirmed at F8,” Mikell Taylor, who served as CEO of Everfly, stated in a message to The Verge. “The group at Otherlab that labored on the FB challenge tried to spin out a startup specializing in commercializing that know-how for extra normal telecommunications functions, however we couldn’t get any traction with funding and the crew parted methods final summer time.” Everfly disbanded later that summer time.
Maguire stated on the F8 stage that the hope with Tether-tenna was that it may present “connectivity to individuals who most want it” for “months at a time,” and that the drone had already flown for 24 hours straight. However he additionally stated that it was “within the early levels of improvement,” and that there have been challenges — significantly as a result of Tether-tenna was working with excessive voltage strains — that might get in the best way.
Tether-tenna was a a lot smaller scale concept in comparison with Aquila, which concerned ultra-light solar-powered drones that had been larger than a 737, and beamed web to the bottom utilizing lasers. However backing away from each is an indication that, whereas Fb nonetheless thinks aerial web is price exploration, the corporate doesn’t wish to cope with the aerial facet of the equation.
When the dying of the Aquila challenge was introduced on the finish of June, Maguire wrote in a weblog publish that Fb as an alternative needs to companion on high-altitude web supply programs going ahead. This permits Fb to deal with issues it’s extra accustomed to, he wrote, like working with the federal government, coping with coverage issues, and fixing issues extra straight associated to the connectivity being supplied.
