Key Activities of the project

Strategic

Three year technology roadmap

A three year road mapping exercise has been completed and published on the wiki.

This workshop established what we have achieved, where we have come from and our vision. The vision is to make a significant contribution to connecting 450 million people sustainably in rural Africa through wireless mesh and other technology with a community grown philosophy. Three product offerings together with the development of their feature sets over a three year period were developed.

  • Africa mesh node (Multi radio node with customized hardware and specialized firmware)
  • DIY mesh kit (Low cost single radio node available off the shelf with specialized firmware)
  • WISP in a box (A custom OS distribution which allows users to establish a wireless ISP business)


Stakeholders & Events

  • DIY Manual: Version 1 of a DIY mesh manual has been produced to help wireless practitioners in the field to quickly and easily build a low cost mesh network. This manual was used in training workshop with Linknet, Zambia.


Collaboration

  • Pretoria Wireless Project (PWP)

We have had discussion with PWP which is an open access wireless network which spans a large part of Pretoria. A technical solution to allow CSIR to peer over the PWP network and visa-versa has been established. This agreement will allow a far larger group of CSIR staff and other Pretoria Wireless users to connect to each other.

  • Linknet

A training workshop and field visit to our Peebles valley mesh project was held with Linknet, Zambia. Linknet seek to provide cost based building, operations and maintenance of targeted and tailored communications infrastructure and services for special interest groups in rural areas of Zambia. Linknet collaborate actively with TNO-ICT in Holland and make use of ICT expertise available in TNO. This collaboration will:

  • Provide another test case for a large deep rural mesh network in Africa
  • Expand our network of partners with similar goals of building sustainable rural wireless networking
  • Serves as an output and feedback point for our mesh product offerings.
