What is internet in a box?
"The Internet in a Box" is an off-line information store that provides instant access to digital resources for those lacking adequate Internet connections. The goal is to provide internet service to schools, hospitals and universities in under served areas around the globe as well as engage librarians and educators to develop custom collections for their communities.
Internet in a box opens up entirely new opportunities for semi-connected schools and offline libraries worldwide, unleashing the best of Internet learning without costs or distractions.
It's possible to install an 'internet in the box' anywhere in the world — even under solar power, using very diverse hardware. Examples include: on a terabyte HD with a built-in hotspot or on a Raspberry Pi. You can buy one of several common versions, or better yet create the digital library needed by your school, your region and/or your very own family.[source]
