This does not come across as a surprise since Facebook also happens to be a founding member of the Internet.org initiative. It is then more or less a given that this particular partnership with Avanti would happen through such an initiative that eventually rests on the hope of delivering the Internet to the two thirds of the world’s population who do not yet have access to it.
Since Avanti is a satellite operator, it does happen to operate its very own space gear that will eventually be used to deliver broadband connectivity to the continent of Africa, especially deep into the inner regions. Right now, Avanti has just a couple of satellites, although it does have plans to send up another two in three years’ time.
