Wireless technologies, such as Worldwide Interoperability for Microwave Access (WiMAX) and Wireless Fidelity (WiFi), are making it easier to provide the much needed telecommunications infrastructure in marginalized areas worldwide. These technologies enable the rapid deployment of network services as well as their redistribution throughout these marginalized areas. The ability to bring Internet connectivity to previously underserviced and marginalized areas has the potential to leap-frog socio-economic development and improve participation in the global knowledge economy. This study investigated how wireless access technologies, such as WiMAX and WiFi, can be integrated and used to deliver ubiquitous distributed Internet connectivity with increased capillarity in rural areas. The research was undertaken within an ICT for Development (ICT4D) intervention called Siyakhula Living Lab (SLL) which is based in the Eastern Cape province of South Africa. The research further eliminated the accessibility constraints associated with long distances and remoteness from the Digital Access Nodes (DANs) and provided increased penetration in the network in contrast to the traditional Telecentre model which has been used extensively in ICT4D interventions. This was achieved by deploying WiFi hotspots around the DANs and extending the existing SLL WiMAX backbone to increase the network footprint to neighboring communities. The technical result of the research has been the provision of increased capillarity on the network and service redistribution throughout the entire Dwesa community. Consequently, this has given local community members an opportunity to access network services easily and ubiquitously. Finally, the research investigated and presented the benefits of such wireless network deployment configurations on ICT4D activities in marginalized areas.
