Internet access is a vital resource for many these days. However, vast, rural areas of the world have no broadband internet access. One of Google’s latest “moonshot” projects seeks to fill that gap with balloons. This undertaking is called Project Loon, and the plan is massively ambitious: it calls for a large network of “towers” in the sky that receive internet access from antennas on the ground in one location and beam internet down to rural homes and locations below. Google has many challenges to overcome before Loon becomes a reality, but the team says it hopes to have a functioning service online by next summer.
Google had first revealed the existence of Project Loon in June 2013 and has tested Loon Balloons, as they are known, in the U.S., New Zealand, and Brazil. The balloons fly at 60,000 feet and can stay in the air for as long as 100 days, keeping their electronics powered by solar panels. Google’s balloons have now traveled more than one million miles total.
These balloons provide wireless Internet using the same LTE protocol used by cellular devices. Google has said that the balloons can serve data at rates of 22 megabits per second to fixed antennas, and five megabits per second to mobile handsets.
