Facebook Is Building Its Own Antennas So That More People Can Use Facebook

Yesterday, Zuckerberg waxed poetic about the future of global connectivity, and now day two of Facebook’s F8 developer conference is giving us more details. Two terrestrial based programs—no nifty drones needed—hope to technically leapfrog fiber with throughput speeds maxing out at a blazing 2.1Gbps.

The first—called Terragraph—uses nodes placed throughout dense urban areas, whether perched on light poles or traffic lights. They sort of look like speakers from a 50s drive-in:


These nodes use what’s called WiGig, basically a souped-up version of wifi that can handle a 7GHz transmission. They also operate on the 60GHz band. The problem with these unlicensed high-frequency bands (most smartphones operate around 700MHz to 1.7GHz) is they can’t travel very far or penetrate obstacles, like buildings, very well. But, man, can they carry tons and tons of data.

To deal with the limitations of the technology, Facebook plans to place these nodes 200-250 meters apart. This closely knit network will then be able to redirect signal around would-be obstacles, theoretically making for a clean connection. It’s an idea not too far removed from the one proposed by Starry, the weird descendent of the now defunct Aereo. However, Terragraph works like so:


But what if you’re one of millions that don’t live in a city? That’s where ARiES, Facebook’s second foray into wireless infrastructure technology, comes in. ARiES, which stands for Antenna Radio Integration for Efficiency, is like the technological middle man between 4G and 5G, specifically built to make spectrum more efficient and all-around better for rural areas.


Long story short, this proof-of-concept would make it possible to support 24 different devices on the same band of spectrum, basically making current 4G connectivity much more efficient and more capable of handling data loads.

By Facebook’s estimation, 97 percent of the world lives less than 25 miles from a major city, and Facebook wants to use Terragraph and ARiES to address the internet needs of the many. Because obviously, more people connecting to the internet means more people can use Facebook. World domination, here it comes.
