Mark Zuckerberg announced on Thursday in a Facebook post that the social networking site was working alongside Internet.org to invent new technology to beam internet to the entire world.
The Facebook (FB) CEO wants everyone to sign up for his site, whether they live in rural Africa or somewhere in the Australian outback. To that end, Facebook's Connectivity Lab plans to connect the entire world to the internet, whether it takes existing technology, or the invention of something entirely new to get it done.
Facebook’s plan is for solar-powered drones to fly over suburban areas, broadcasting the internet to areas below, as well as satellite systems that span as far as entire continents to beam it to “user terminals” in low population densities. The Connectivity Lab’s satellite system sounds a lot like Google Inc’s (GOOG) Project Loon, one of the search giant’s “moonshots” with similar aims, to connect those in remote areas.
Whereas Google’s Project Loon will use a network of hot-air balloons to send the internet to terminals similar to the ones that Facebook’s Connectivity Lab plans to use for its satellites, the social network has acquired UK-based Ascenta for $20 million to build solar-powered drones to connect more highly-populated, suburban areas. Ascenta will work alongside teams Facebook acquired from NASA’s Jet Propulsion Laboratory, Ames Research Center, as well as the National Optical Astronomy Observatory.
As former MIT visiting scientist and Facebook employee Yael Maguire explains it, the drones will employ a “new type of plane architecture that flies at 20,000 meters,” or 20 km, which allows them to be unaffected by commercial airlines, wind and the weather. Maguire says they will be capable of remaining “in the air for months at a time.”
For rural areas with low population densities, Facebook’s Connectivity Labs plans to employ satellite systems. Maguire says they could span “perhaps even across continents” in a low Earth orbit. The satellites will then be “constantly moving… [which] necessitates a steady stream” of internet signal as well as a “user terminal” for those on the ground to receive the satellite broadcast.
Maguire says there exists a “fabulous set of problems” to make the satellites work, which the Connectivity Lab plans to solve with lasers. The problem, as he describes in a YouTube video, involve how broadcast networks are currently bound to satellite towers that require a terrestrial connection to the internet.
Lasers are proposed to offer a wireless connection to the Connectivity Labs’ satellite system, and could offer high speeds on par with “fiberoptics,” Maguire says. Facebook did not immediately respond to a request for comment about when or where it will begin testing the Connectivity Labs project.
Here is the full text of Zuckerberg’s statement:
In our effort to connect the whole world with Internet.org, we've been working on ways to beam internet to people from the sky.
Today, we're sharing some details of the work Facebook's Connectivity Lab is doing to build drones, satellites and lasers to deliver the internet to everyone.
Our goal with Internet.org is to make affordable access to basic internet services available to every person in the world.
We've made good progress so far. Over the past year, our work in the Philippines and Paraguay alone has doubled the number of people using mobile data with the operators we've partnered with, helping 3 million new people access the internet.
We're going to continue building these partnerships, but connecting the whole world will require inventing new technology too. That's what our Connectivity Lab focuses on, and there's a lot more exciting work to do here.
Our team has many of the world's leading experts in aerospace and communications technology, including from NASA's Jet Propulsion Lab and Ames Research Center. Today we are also bringing on key members of the team from Ascenta, a small UK-based company whose founders created early versions of Zephyr, which became the world’s longest flying solar-powered unmanned aircraft. They will join our team working on connectivity aircraft.
You can find more details on our efforts below. We're looking forward to working with our Internet.org partners and operators worldwide to deploy these technologies and deliver on the dream of connecting the world.
