How the Outernet is connecting schools in Kenya
Around two-thirds of the world's population still has no internet access - so how can the poorer and more remote parts of the world get connected?
The answer could be through the Outernet - a system providing content beamed down to earth via satellite and picked up by antenna-fitted receiving equipment on the ground generating local wi-fi hotspots.
The hotspots then enable users to download data on their smartphones or computers for later use.
BBC Click's Spencer Kelly went to see the system in action at a school in Kenya and met the entrepreneur behind the idea, Syed Karim.
The system does not provide a full internet service but aims to create a "core archive" of the world's most valuable knowledge, culled from websites including Wikipedia and Project Gutenberg, a collection of copyright-free e-books. Content is updated periodically.
It can also provide more time-sensitive content - including news bulletins and disaster alerts - that can be updated several times an hour.
