Loon

Loon is a network of high altitude balloons used to provide stable internet coverage on the ground. Project Loon balloons float in the stratosphere, twice as high as airplanes and the weather. In the stratosphere, there are many layers of wind, and each layer of wind varies in direction and speed. Loon balloons go where they’re needed by rising or descending into a layer of wind blowing in the desired direction of travel. By partnering with telecommunications companies to share cellular spectrum we’ve enabled people to connect to the balloon network directly from their phones and other LTE-enabled devices. The signal is then passed across the balloon network and back down to the global Internet. Loon is a subsidiary of Alphabet, Google's parent company. The Mountain View, California-based company was founded in 2011.
