- Description: Information Communication Technologies (ICTs) have diffused into al-most every area of life for citizens living in the Global North. Data is seen as a key element in the fourth industrial revolution and is the foundation of Information, Knowledge and Wisdom. Knowledge has become the new “make or break” asset and an inability to access the world’s data and technologies that facilitate access, synthesis and inter-rogation of data places one at a disadvantage. In 2013, the Department of Communications in South Africa announced a new national broad-band policy to promote the reduction of a digital divide and sup-port citi-zens and the economy in digital interactions. Implementation has thus far not been successful. Furthermore, the Broadband policy does not address how South Africans are to access the Internet once available. The Siyakhula Living Lab (SLL) provides an example of a computing infrastructure model for the introduction of ICTs into rural communities. Through the deployment of “broadband islands” and low-cost compu-ting infrastructure to promote both knowledge creation and consump-tion, access to the proposed ubiquitous Internet connectivity can be un-locked. However, the initial computing infrastructure deployed to the SLL suffers from a single point of failure. In this paper, we discuss al-ternative computing infrastructure configurations that were tested and deployed within the SLL in order to determine a more appropriate com-puting infrastructure model for the SLL and potentially other rural South African communities; such that learners, teachers and community members can be active contributors and consumers of data, infor-mation, knowledge and wisdom.

- Description: Information and Communication Technologies (ICTs) are increasingly considered valuable tools in educa-tion, promoting the development of higher cognitive processes and allowing teachers and learners access to a plethora of information. This paper reports on two pilot studies conducted in South Africa in proto-typical previously disadvantaged schools and their surrounding communities. Each pilot study deployed a local loop network within impoverished communi-ties, connecting schools to one another and central services such as email and voice communications. The benefits of these networks were that teachers, learners and the local community had access to in-formation, and communication and collaboration channels, providing potential test beds for investigat-ing the use of computers as mind tools.

- 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.
