I'm a software developer from England, interested in the OLPC project and the expansion of the internet overseas. I'm not a member of the OLPC organization, just someone with a few ideas to contribute. My main interest is the different ways of linking schools to each other in areas where internet-access isn't available/affordable right now. This is for transferring email and files (eBooks, Software, news, etc) and for communication with the rest of the world. |
|||
So far, I've contributed to... |
|||
[[Radio and broadcast]] - This article was started by someone else and contains several methods for the 1-way transmission of eBooks, Software, news and other files to schools, by Radio, TV and Satellite. It also covers the 2-way transmission of files by radio, for web-access, file transfer and email. |
|||
My own ideas on the page are :- |
|||
# Broadcasting files in the spare multi-language audio subcarriers of Satellite TV channels. |
|||
# 1-way broadcasting files by embedding hidden audio signals within the music/speech audio signal of existing commercial/public-service radio stations. This allows ordinary cheap radios connected to a laptop to receive the data. |
|||
# 2-way transmission of files along a chain of radio stations, where each station transmit files and messages to the other using audio signals hidden in the music/speech (like idea No. 2, but bi-directional). |
|||
Some of the ideas on that page, contributed by various people, might make good student-projects or spare-time software/hardware projects. |
|||
I've created :- |
|||
* A [[Sneakernet]] page, for file transfer between schools on USB Flash Drive. |
|||
* An [[Optical data link]] page, for fast light-beam data links between buildings, etc. |
|||
I've listed several internet-access technologies/articles on the [[Internet]] page. |
