Facebook testing method to deliver Internet using lasers

As part of its efforts to bring Internet connectivity to billions of people who do not live in the vicinity of existing wired or wireless networks, Facebook is working on ways to use drones and satellites.

In a Facebook post, Mark Zuckerberg, said, "Our Connectivity Lab is developing a laser communications system that can beam data from the sky into communities. This will dramatically increase the speed of sending data over long distances. Normally you wouldn’t be able to see the actual beams, but for this demonstration we made them visible. This is just one connectivity project we’re working on, but I was excited to share this with you."

In the past, Facebook has spoken about Free Space Optics as a method to provide extremely high bandwidth and capacity, at part with terrestrial fiber optic networks.

Besides Facebook, Google is also working on a project to bring Internet access to places that do not have Internet connectivity. You can read about Project Loon here
