Iskratel top of the world with Potosí fibre-optic deployment GPON broadband network deployed to meet the needs of thousands of residents in the highest city in the world Share this item with your network: By Published: 07 Jan 2021 10:07 Just as western European communications operators struggle to make the case for rolling out gigabit broadband networks to rural parts of technologically advanced countries, the residents of a Bolivian city sitting over 4km above sea level are to receive a fibre broadband connection thanks to the deployment of gigabit passive optical network (GPON) broadband. Potosí is the world’s highest city at 4,090 metres above sea level, resting at the foot of its Cerro Rico (rich mountain) that rises up to 4,800 metres. The city was once one of the richest in the world, and in 1650 its population exceeded cities such as London, Seville, Madrid, Rome or Paris.
