Gender and participation: critical reflection on Zenzeleni Networks in Mankosi, South Africa
(ACM, 2016-11-25)This paper unveils the complexity of gender dynamics by reflecting on lessons learned in Zenzeleni Networks and provides a different perspective to notions of “participation” by asking “who participates and how?” The paper ... -
Development consortium: HCI across borders
(Association for Computing Machinery, 2016)Though every country and context is unique, and much of HCI research aims to design for situatedness, there are lessons to be learned across borders, across contexts. Questions we ask include: What are common themes ... -
Making a community network legal within the South African regulatory framework
(ACM, 2015)Community networks often operate at the fringe of legality with respect to spectrum, network infrastructure and providing services. We have been involved with such a network in a rural community, and together with them, ... -
Towards a scalability model for wireless mesh networks
(Telkom, 2015)Zenzeleni mesh network is a wireless ad-hoc mesh network that provides voice services using public analogue telephones to the Mankosi community in the Eastern Cape Province. We would like to improve on the network ... -
Beyond traditional ethics when developing assistive technology for and with deaf people in developing regions
(Springer, 2015)There are limitations to traditional ethical approaches and procedures when engaged in assistive technology (AT) research for Deaf people in a developing region. Non-traditional issues arise as a consequence of employing ... -
Clustered Multi-layer Multi-protocol Wireless Mesh Networks
(Telkom, 2015)Wireless Mesh Networks (WMNs) have emerged as an alternative option to the wired networks in areas where wired deployment is unfeasible and/or costly. They have been widely adopted in community networks as these networks ... -
ICT4D and Local Access
(John Wiley & Sons, 2015)Local access in the context of regions in the global South continues to undergo transformation due to the growing ubiquity of mobile connectivity and the recent appearance of what have been termed “inverse” telecommunication ... -
Usability of an authoring tool for generalised scenario creation for signsupport
(Telkom, 2015)This paper presents the usability testing results for an authoring tool that generalises scenario creation for a tool called SignSupport. SignSupport is a mobile communication tool for Deaf people that currently runs ... -
Local ownership, exercise of ownership and moving from passive to active entitlement: a practice-led inquiry on a rural community network
(CCIRDT, 2015)In this paper, we aim to shed light on local ownership from a double practical and theoretical perspective, and examine its meaning as well as the factors that are bound to influence its development in community based ... -
A participatory design for a billing system: A South African case study of a community based telephony system
(ACM, 2014)This paper describes the role participatory design can play in developing and implementing an information and communication technology for development project in a rural area. It shows how the process of co-designing an ... -
Rural Wireless Mesh Network Analysis on Mobile Devices
(Telkom SA, 2014)The aim of this research effort is to build an efficient and accurate mobile traffic generator based on open source computer-based traffic generator software. A high performance mobile traffic generator would make the ... -
An analysis of voice over Internet Protocol in wireless mesh networks
(IEEE, 2014)The paper focuses on analyzing the affects of wireless mesh networks with some mobile nodes on Voice over Internet Protocol service quality. Our interest is to examine this in simulation to learn how to better deploy voice ... -
Co-designing a billing system for voice services in rural South Africa: Lessons learned
(ACM, 2014)Access to information and communication technologies re- mains una ordable for many in rural areas despite recent progress in providing voice services to remote communities. The sustainability of alternative technical ... -
Towards communication and information access for deaf people
(SAICSIT, 2014)In tightly circumscribed communication situations, an interactive system resident on a mobile device can assist Deaf people with their communication and information needs. The Deaf users considered here use South African ... -
Optimisation of SlotTime for a single-radio Mid-Range Multi-hop Wireless Mesh Network
(Telkom SA, 2014)This paper presents the business context and results of an optimisation exercise for a single-radio mid-range multi-hop wireless mesh network for the provision of VoIP services. This WiFi mesh network physically covers 30 ... -
Abstractions for designing and evaluating communication bridges for people in developing regions
(ACM, 2010)This paper describes two novel abstractions that help soft- ware engineers work in developing regions to align social and technical factors when building communication systems. The abstractions extend two concepts familiar ... -
Performance Evaluation of a Wireless Network using a VoIP Traffic Generator on a Mobile Device
(ACM, 2014)The problem of generating different patterns of traffic to emulate real user behaviour is receiving considerable attention with the construction of new and more complex network architectures. The theoretical modelling of ... -
A framework and toolkit for the collection and analysis of QoS statistics for voice traffic in Next Generation Networks
(Telkom, 2000)The multi-service, multi-architecture nature of NGNs is so complex that the management of services, in addition to networks, emerges as a research challenge. Despite QoS limitations, VoIP (as opposed to VoATM), dominates ... -
Empowerment of rural farmers through information sharing using inexpensive technologies
(ACM, 2011)This paper discusses how to empower rural farmers to do business by means of inexpensive mobile technologies. In particular, the aim is to take advantage of the inexpensive features of low-end mobile phones to access market ... -
Comparative study of admissions criteria of a selection of South African universities
(Stellenbosch University, 2011)Summary: The new school-leaving certificate, the National Senior Certificate (NSC), was awarded for the first time in 2008. This necessitated a relook at the entrance requirements for university, as the school subjects ...
