Inflatables use solar-powered, high-altitude balloons to provide internet service in remote regions
Alphabet's Loon balloons to boost coverage in storm-hit Puerto Rico
Experimental communications balloons provided by Alphabet in collaboration with AT&T will allow some of the carrier's customers in storm-ravaged Puerto Rico to send texts and access critical information on the internet, Alphabet said.
Alphabet said the "Project Loon" balloon project would deliver limited internet connectivity to LTE enabled phones in the hardest-hit areas of Puerto Rico.
The island's wireless and broadband communications networks were devastated after Hurricane Maria made landfall last month.
This month, the US federal communications commission (FCC) approved Alphabet's application to provide emergency cellular service to Puerto Rico using up to 30 balloons. The company said on Friday it does not expect to use that many since each balloon can provide internet service to an area of about 5,000 square kilometres, or 1,930 square miles. Puerto Rico's area is 3,515 square miles.
The company has a handful of balloons in the area and more are on the way, said the spokeswoman Libby Leahy.
Since Hurricane Maria, Puerto Rico has struggled to regain communications services. As of Friday, 68 per cent of mobile sites remained out of service, the FCC said.
Alphabet, which announced its Project Loon in 2013 to use solar-powered, high-altitude balloons to provide internet service in remote regions, said in an FCC filing it was working to support carriers as they restored "limited communications capability" in Puerto Rico.
The FCC chairman Ajit Pai said this month he was forming a Hurricane Recovery Task Force focused on communications problems in Puerto Rico and the US Virgin Islands.
Alphabet said this was "the first time we have used our new machine learning powered algorithms to keep balloons clustered over Puerto Rico, so we’re still learning how best to do this. As we get more familiar with the constantly shifting winds in this region, we hope to keep the balloons over areas where connectivity is needed for as long as possible."
Alphabet said it will continue the project as long as it can usefully do so. "Project Loon is still an experimental technology and we’re not quite sure how well it will work."
In 2016, Project Loon delivered service to tens of thousands of people in flood-damaged parts of Peru in partnership with the Peruvian government and Telefonica.
Alphabet, which launched the balloons in Nevada, said Project Loon is already providing service in Puerto Rico. It is part of an innovation lab within Alphabet that the company calls X, previously known as Google X.
