I'm excited to announce we’ve completed construction of our first full scale aircraft, Aquila, as part of our Internet.org effort. Aquila is a solar powered unmanned plane that beams down internet connectivity from the sky. It has the wingspan of a Boeing 737, but weighs less than a car and can stay in the air for months at a time. We've also made a breakthrough in laser communications technology. We've successfully tested a new laser that can transmit data at 10 gigabits per second. That's ten times faster than any previous system, and it can accurately connect with a point the size of a dime from more than 10 miles away.This effort is important because 10% of the world’s population lives in areas without existing internet infrastructure. To affordably connect everyone, we need to build completely new technologies. Using aircraft to connect communities using lasers might seem like science fiction. But science fiction is often just science before its time. Over the coming months, we will test these systems in the real world and continue refining them so we can turn their promise into reality. Here’s a video showing the building of Aquila.Posted by Mark Zuckerberg on Thursday, July 30, 2015
The world-wide web is not as ‘world-wide’ as we have assumed it to be. For many of us, the internet is a ubiquitous thing. However, as of writing this, stats indicate that only 40% of the world population has internet connectivity. And 10% of the population lives in areas where there is no internet infrastructure in the first place. This is the motivation behind ‘Aquila’, an unmanned aircraft built in association with Facebook’s Internet.org, which aims to increase the ‘reach’ of the internet to people, in a very literal way.
The Aquila is a solar-powered plane, with a wingspan of more than that of a Boeing 737, while still weighing less than a car. It is made almost entirely out of carbon fiber, a modern composite material which is lighter and yet more rigid, than any traditional metal. The result of this lightness means that the plane can fly at higher altitudes than commercial jetliners, and stay in flight for unprecedented periods of time. Specifically, the Aquila is designed to fly at 60,000 feet (compared to 30,000 feet flying altitude of commercial jetliners) for 3 months at a time.
Now onto the connectivity front. The plane is loaded with communication equipment. It will receive internet signals from a base station located somewhere on the ground and then relay those signals to other Aquilas around itself, as well as to other localized regions elsewhere on the ground, to provide internet connectivity using spot beams. The plane will use radio (RF) communication and lasers. Imagine the plane as a router in the sky which happens to drop internet, instead of bombs. Hence the twitter tag #DropInternetNotBombs. The communication speed is aimed to be 10gigabits per second. It’s not a typo.
For those of you who know your Google from your Facebook, you might have heard about a similar project called ‘Loon’, by Google. An idea similar in principle, Loon was going to perform the same task i.e providing internet connectivity to remote areas, using especially designed high-altitude balloons.
Any effort to improve communication around the globe is an important one. It also pushes the frontiers of technology in the best possible way.
