The Alliance will push for governments to adopt high-altitude internet, of course, but it'll also work on a cooperative environment with common specs and standards. The aim is ultimately to create a single "compelling message" to sell the concept, even if the individual companies end up competing with each other.

This comes roughly 10 months after Loon forged a deal with SoftBank's HAPSMobile to press for high-altitude broadband.

Whether or not the HAPS Alliance succeed is far from certain. Loon has landed deals to supply internet to underserved people in places like Puerto Rico, Kenya and Peru, and has been venturing beyond its signature balloons to explore internet drones. In many ways, high-altitude internet is already off to a good startIt's still early days, though, and the Alliance will need to show that there's a roadmap for its technology, not just a set of well-meaning ideas.
