Connecting Cape Town: Inside SA's TV White Spaces Experiment

In the whole of Africa, just 15.6 percent of residents are connected to the internet, which is under half of the world average. It's also home to vast, inhospitable landscapes that are economically inviable to crisscross with fiber. All of that being said, nearly a sixth of the globe's population resides on the continent, representing a monumental opportunity for something -- anything -- to connect the next billion people. As it turns out, there are actions presently ongoing to make a significant mark in the course of history. Google, Microsoft, Carlson Wireless, Tertiary Education and Research Network of South Africa (TENET) and a host of other powerful entities are collaborating to bring high-speed internet to an underserved continent via TV white spaces -- a low-cost, highly adaptable technology that's poised to explode. For now, Cape Town, South Africa, is acting as a proving ground for what will eventually be a far larger experiment. The core goal is actually quite simple: to beam hope to a disconnected society, with unused bands between TV channels acting as the medium.

Will see what happens with unencrypted data. Cable is still the best way of getting communication across imo.

Stupid idea is stupid.

TV is great for broadcasting a few streams of information to a wide audience, but those people can only act as receivers, the band is too wide for every receiver to firstly receive its own unique data, and secondly to send data back up the line.

Anyone remember Siyanda? You could receive data pretty quickly (by mid 90's standards) but you needed a dial-up modem to send data back upstream.
Similar hurdles to overcome here.

At best white-space could be used to broadcast data to people en mass, but it will not even remotely resemble the traditional internet we know.
