Google parent Alphabet Inc is shutting down its internet balloon business, Loon, which aimed to provide a less expensive alternative to cell towers, saying on Thursday that it was not commercially viable.
Founded in 2011, Loon aimed to bring connectivity to areas of the world where building cell towers is too expensive or treacherous by using balloons the length of tennis courts to float solar-powered networking gear high above the Earth. But the wireless carriers that Loon saw as buyers of its technology have questioned its technical and political viability.
“While we’ve found a number of willing partners along the way, we haven’t found a way to get the costs low enough to build a long-term, sustainable business,” Loon Chief Executive Alastair Westgarth said in a blog post.
Launched in 2013, the project was piloted in different parts of the world including Kenya where the company partnered with operator Telkom.
In March 23, 2020, President Uhuru Kenyatta announced the Kenya Civil Aviation Authority (KCAA) had signed an agreement with Alphabet to allow their balloons to fly over the Kenyan airspace beaming high-speed internet.
“This intervention will enable Kenya to retain her competitive advantages in ICT and innovation in the midst of the current crisis; while at the same time laying the foundations for greater expansion once the current health challenge is contained,” said Mr. Kenyatta.
“The problem got solved faster than we thought,” he said in an interview.
Westgarth said Loon’s legacy would include advancing helium balloons to last hundreds of days in the sky and developing communications equipment that could deliver cell coverage across an area 200 times bigger than an average tower can.
But among challenges were that a carrier would need several balloons at once, and each balloon cost tens of thousands of dollars and lasted only about five months.
Loon launched a pilot project in Kenya in 2020, years behind schedule after regulatory delays. Its partner, Telkom Kenya, did not immediately respond to a request for comment.
The technology previously proved successful in short projects to provide cell coverage in Peru and Puerto Rico when cell towers were downed by natural disasters. The company had pitched countries and international organizations on contracting with Loon to fly in during future emergencies, but gained little traction.
Loon said it may share its technology with carriers, governments or nonprofit groups aiming to bring high-speed internet to the last few places in the world.
The company employed 200 people as of 2019. It drew a $125 million investment that year from SoftBank’s HAPSMobile, which is working on floating cell equipment with drones.
