Hi Joash,
This is a great piece of video journalism from the BBC but a minor point of clarification. Zenzeleni is not a mesh network. It did start out as one but now uses hub and spoke WiFi technology from Ubiquiti just like Mawingu and many others do in Kenya. The BBC unfortunately buried the lead in the headline by not highlighting the real innovation of Zenzeleni, which is the nature of their organisation. They are a registered cooperative under South African law. Profits from the network go back to the community and back into the network. Cooperatives have been around since the middle ages. Their time is coming for rural broadband.
Cheers... Steve Song
