In 1998, Globalstar and Iridium began the race to connect the world via voice and data services. These pioneers of satellite communications sadly went under in the end. It seems the world wasn’t ready for them.
Now we are way more connected than we were in 1998, so Google is looking to try the space internet thing again. Their methods are quite different, though. They plan to use unmanned aircraft to create a wireless internet net, mainly in undeveloped countries. The idea is to find a way to get people in underdeveloped areas access to the same internet the rest of the world is using.
The Titan Project will use unmanned solar-powered drones to fly 65,000 feet in the air. They can stay airborne for over five years and can carry a large enough payload to deliver wireless internet speeds of 1 Gbps.
Project Loon uses high-altitude balloons that can remain afloat for up to 100 days. The payload they can carry is much smaller than that of the Titan Drone, and it therefore the internet speeds it can provide are much slower. But this method is more likely to be accepted by those on the ground than is an unmanned solar-powered drone.
