Set up a communication network that replaces expensive copper transmission wires with a system that piggy-backs on a local transportation system. Initially this would be aimed at education.


Additionally, there are some constraints - mostly financial. There are two parts of the cost equation - capital costs for equipment, and running costs of the operation.

An example setup

A school in Zululand wishes to teach computer skills to its students. Additionally, teachers at the school want access to teaching materials freely available on Internet. Also, we would like to arrange for Email access from the schools to the rest of Internet.


There is a large amount of free software currently available on Internet, and I would select Linux and the software that runs on this free Unix operating system as the basis for this project. Much of it is of high quality, and geared towards Internet, Email, and the World-wide web.

The Netscape browser runs on this platform, and is free.


Radio Telex


The advantages over conventional telephone systems


If we use portable mass storage, like ZIP drives, reliability of delivery might be a problem

If we use radio, securing the bandwidth is crucial for success

Radio Telexes must be left on all the time. The system depends on being able to route through (maybe) idle Radio Telexes. There is the possibility that someone may think it unreasonable to be paying for electricity just to route somebody else's mail.

There is no control over communication, or monitoring. Some would construe this as being a Good Thing.

Similar networks exist today. Two very relevant ones are the Amateur Packet Radio networks in the USA and Europe, and the Internet UUCP computer network
