Project Loon, started in 2016, uses high-flying balloons powered by on-board solar panels as Wi-Fi carriers to deliver signals from above. Alphabet spun out Loon in July from X, the division of Alphabet responsible for its most experimental projects, including self-driving cars, internet-connected contact lenses and delivery drones.

The company said previously it was planning a commercial launch of Loon later this year. Thus far, the balloons have only been used in testing, and deployed for emergency relief, as in the aftermath of Hurricane Maria in Puerto Rico.
