Africa Fiber in 3 Maps: Coast thriving, Center a desert
Africa in 2015 has ~400M people with mobiles despite no signal where almost a third of the population live. Ericsson counts 170M smartphones in sub-Saharan Africa in 2015 and expects a remarkable 500M more in the next five years. 3G coverage in Q1 2016 is only 43% (GSMA) but increasing rapidly. The first map, from Afterfibre, very colorfully slows the emerging fiber networks. (Red are projected.) The third, from Paul Hamilton, has similar data but less color. It's easy to see the fibre desert in Central Africa. #2 is from the remarkable Steve Song, showing the undersea cables. Almost all have been built in the last five years. South Africa is served by five cables; Kenya and most of West Africa by three. Prices are a fraction of what satellite used to charge but in many places still very high. Larger versions below.
Not quite as low as the $0.27/megabit price in Riga. Hurricane Electric, a major Internet backbone, is coming to Africa. Although they aren't announcing prices, I predict they will offer much less expensive backhaul/transit. Most of the continent suffers from brutally high, cartel-like prices for wholesale connections. If HE prices as I expect they will, that could easily reduce consumer Internet prices by 15% to 35%. In turn, that will allow tens of millions more to connect. 
120M Chinese have fiber home connections, more than the entire rest of the world. That's actual connections (including businesses), not availability or homes passed. When I first saw that figure in Google translation from the Chinese, I thought it a program problem. But now the authoritative Point-Topic data confirms it. P-T counts 213M Chinese connected at the beginning of this year, a number confirmed by financial filings and government data.
Years away, while DOCSIS 3.1 can do an upstream gigabit today. If the wireless guys think they can go both upstream and downstream on the same frequency, why can't cable? Alcatel has already 
Added half a percent of the Internet's users each year over the past two decades." Iljitsch van Beijnum has captured the status in a great headline. There is no unifying force that implements Internet rules. Each of the network of networks takes its time. 
FT/Orange Spain going to 10M & 14M. Without much publicity, Spain has pulled far ahead of other large nations in fiber homes. The U.S., Italy and France have passed fewer than 25%, Germany and England less than 10%.
