The high-flying drones would give Facebook the ability to beam wireless Internet access to consumers in undeveloped parts of the world.
The technology blog TechCrunch first reported the deal late on Monday, citing an anonymous source.
The effort would help advance Facebook’s Internet.org effort, aimed at connecting billions of people who do not currently have Internet access in places such as Africa and Asia.
Facebook declined to comment.
Titan Chief Executive Vern Raburn declined to comment on whether Facebook was buying the company or a large order of its planes.
“I can’t comment one way or the other,” Raburn said in a telephone interview on Tuesday.
Titan is developing a variety of solar-powered “atmospheric satellites,” according to the company’s website, with initial commercial operations slated for 2015. The drones, which fly at an altitude of 65,000 feet (20 km) and can remain aloft for up to five years and have a 165-foot (50-metre) wingspan, slightly shorter than that of a Boeing 777.
Facebook, which has 1.2 billion monthly users, has partnered with numerous wireless providers in recent years to offer free or discounted access to the social network. But some, such as Vodafone (VOD.L), have balked at waiving their wireless data rates for Facebook.
