The company's Project Loon technology was developed by Alphabet's X lab. It has since become Loon, a subsidiary of Alphabet, which is the parent company of Google.
The technology was used by U.S. telecom operators to provide connectivity to more than 250,000 people in Puerto Rico after a hurricane last year. Kenya hopes the technology can help achieve full Internet coverage of its population.
Telkom Kenya is the third biggest operator in the country.
The Loon service uses balloons, which are powered by an on-board solar panel, to provide fourth generation (4G) coverage to areas with lower population densities. They float at 60,000 feet above the sea level.
