Project Loon is a Google project that aims to provide internet access to rural and remote areas using high-altitude balloons. The balloons float in the stratosphere and work together to form a wireless network with long-range radio links. This network is used to beam an internet connection to users on the ground with special antennas. The balloons are steered by rising and falling to different wind layers to remain over desired regions. The goal is to give more of the world access to broadband-like internet using renewable energy through a network of balloons.
