- Description: With an alarmingly low teledensity in South Africa, just 12%, and not much hope of further wired infrastructure at the local loop level, as the costs incurred are high compared to potential revenue, wireless con-nectivity could be a great asset and service in South Africa. However, the use of unlicensed spectrum in building wireless networks can be comparable to “The Tragedy of the Commons”, the result of selfish be-haviour towards common and limited resources. This paper evaluates the use of 802.11 wireless technologies in building a broadband wire-less network and the effects of high amounts of interference on such a network. The paper concludes that for urban areas 802.11 technologies using unlicensed spectrum is not advisable, unless used in point-to-point links, while its use in rapid rural development (where there is less interference) is very promising.

- Description: With an alarmingly low teledensity in South Africa, less than 5% in some rural areas, and not much hope of further wired infrastructure, as the costs incurred are high compared to potential revenue, wireless connec-tivity could be a great asset and service in South Africa. This paper looks at how wireless communication technologies, 802.11, WiMAX and VSAT, can be used to allow broadband connectivity of schools to the Internet, with special reference to experimental work that is being done in Grahamstown schools.

- Description: Computers are increasingly considered a valuable tool in Education, not only for the purpose of administration but also for teaching and learning. This project aims to model Internet connectivity to previously disadvan-taged schools in the Eastern Cape by investigating known networking technologies in the context of such schools. We look at wired and wireless technologies, while bearing in mind issues such as cost, organisation ca-pacity and such like.
