It’s not a total success, which isn’t to be expected after Puerto Ricans’ communications infrastructure suffered so much damage. But the team was able to work with AT&T and T-Mobile to get “communication and internet activities like sending text messages and accessing information online for some people with LTE enabled phones,” head of Project Loon Alastair Westgarth wrote in a blog post. The team launched their balloons from Nevada and used machine learning algorithms to direct them over Puerto Rico, where they’ve been relaying internet from working ground networks over to users in unconnected areas.
In the post, Westgarth noted that Project Loon has never fired up internet from scratch this rapidly, and will improve their ability to keep balloons in place (and deliver sustained connectivity) as they become familiar with the air currents. They owed a lot to all manner of collaborators, from the mobile carriers to Pan-American and Puerto Rican governments’ aviation authorities to local communications companies.
“In times of crisis, being able to communicate with loved ones, emergency services and critical information is key,” Westgarth said in a statement provided to Engadget. “We hope that the connectivity Project Loon has provided over the last few weeks has been helpful, and would like to thank AT&T, T-Mobile, and our government partners who made these efforts possible.”
