Folks,

The link below points to a pdf of some Impress slides outlining a low cost ($100 per receiver), fast (up to 80Mbps), solar powered (4Watt receiver) content delivery network for the One Laptop Per Child project. With a monthly cost of around 25 cents/student in large deployments it could be implemented immediately, and is complementary to other Internet connectivity such as Wifi mesh, data-mule, or two-way satellite.

This is still a draft. After perusing this, please use the push button feedback form here: Feedback Form
or send me an email. I would very much like to hear your comments.

I intend to do a version 2 that gets down to actual satellite link budgets, and exact costs, based on a traffic model and deployment scenario, but at this point I need feedback and perhaps a little debate from people out in the OLPC community to keep me on course.
