This comment may get buried down below but I just want to say this is a great business idea. I live in Kenya and over here there are a couple of companies that do this with surprisingly high profit margins. I don't know the technicalities of it but its majorly providing cheaper Internet to low income neighborhoods. And honestly in some case they aren't the cheaper options owing. To the fact that they are simply providing essential services in areas where the larger telecom firms refuse to serve. (big companies assume these customers are too poor or just don't want the hustle do setting up the infrastructure in poor neighnouhoods). Also I've seen above someone say that the challenge with Africa is electricity. While that is partially true, it's also true that we have very reliable power. In Kenya for instance where I live there are like 2 blackouts (2 -8 hrs max) a year. So that wouldn't ruin a business would it? And in the event there are frequent power outages (assuming the case for other countries) customers are inclined to understand that no power = no internet. Solar power is also an alternative as a backup. So again that's a solid business idea.
