Google aims high to restore connectivity to Puerto Rico

Puerto Rico is still struggling in the aftermath of Hurricane Maria, with communications a particular problem. More than 90 per cent of the mobile phone masts on the island were downed by the storm, and as of 6 October, 83 per cent had not been restored.

To help address this problem, the Federal Communications Commission has granted Google’s parent company, Alphabet, a special experimental license to operate in Puerto Rico and the US Virgin Islands, allowing it to deploy high altitude helium balloons, developed by its subsidiary Project Loon, to deliver emergency cellular coverage to the stricken area, so that residents can contact family and friends and to help coordinate relief efforts.

Project Loon is one of what Google describes as its ‘moonshot efforts’. It uses helium balloons to act as high-altitude pseudo-satellites (HAPS), carrying equipment up to altitudes of 65,000ft (almost 20km) to receive mobile phone signals and relay them to the ground.
