⌘Expectations towards global coverage
- According to Ericsson, Mobile Technologies are available for 50% of the world's population (2013), and the coverage will increase to 75% by 2017.
- According to Internet.org (Facebook, Opera Software, ....), only 1/3 of the world's population has access to the Internet (2013).
- An extrapolation by the Basic Internet Foundation points out that even in 2017 about 45% of the population will not have access to Internet, mainly due to affordability. Thus they promote the free access to basic information of the Internet, being text and pictures.
