Join Africa
From their website:
JoinAfrica is a ground-up movement that enables local communities to build and sustain their own wireless networks in Africa. Our goal is to have WIFI access throughout Africa by 2020
Join Africa was created by an international collaboration focused on demonstrating that individuals and local communities can sustainably build, operate and monetise broadband networks on a large scale. Designed on the principle of universal access, the JoinAfrica system uses excess paid capacity to provide limited free connectivity as a public service. This "freemium" model of service delivery helps to build local online communities faster while allowing local operators enough revenue to sustainably maintain and grow their networks.
