We analyse a set of network traces from the LinkNet wireless network in Zambia, which provides Internet access to approximately 300 residents of a rural village using a satellite link and a combination of point-to-point links, hotspots and wireless mesh networks. Our analysis reveals largely web-based traffic as opposed to the peer-to-peer traffic dominance that one finds in urban areas. Social networking sites receive the most hits, and large file downloads from operating system reprositories contribute the most to the bandwidth consumption. A number of network pathologies in the gateway as well as the wireless mesh network are also analysed and a set of recommendations conclude the work.

There has been considerable hype behind Wireless Mesh Networking as the ubiquitous solution for rural ICT in the developing world. In this paper, we present the real world rural mesh network implementation in the village of Macha, Zambia and draw both performance conclusions as well as overall experiential conclusions. The purpose of this paper is to introduce and analyze our low cost solution and extrapolate future trends for rural ICT implementations in Zambia.
Macha Works!

Macha is a small and resource limited village in rural Zambia. Since 2003 remarkable progress is taking shape in Macha. Since that time, the village is connected to Internet via a VSAT satellite connection, integrated with a holistic and respectful vision based upon developing the potential of the local community. Thus the local community plays a major role in the development process.
To operate the communications network a cooperative not-for profit company was set up, Macha Works, with its ICT unit LinkNet, owned by the community.
Overall the Macha approach appears very successful and is now being scaled up to many more villages in Zambia. Macha itself is in a next stage of development. It is evolving into a center of expertise with training, talent development, innovation and experimentation in the fields of agriculture, alternative energy, appropriate types of entrepreneurship, and novel approaches in ICT fitting the African context. A cooperation with the University of Zambia in Lusaka is evolving with education, applied research, and practical work taking place in rural Macha. Hundreds of new employment positions have been created since Macha Works started its activities.
Connecting rural communities in Africa is quite a challenge. Communication and energy infrastructures are lacking. Connectivity through satellite links are extremely expensive. Mobile Internet might be an alternative in the medium term. Introduction of Virtual Network Operations to share costs can support reaching the marginal, rural markets.
The value of the holistic approach driven by connectivity has been recognized and the development in Macha is now supported by organizations and authorities in Zambia, Netherlands, the Global Research Association and European partners. Connectivity appears to be a powerful tool to empower the local community to guide their own development. In addition, two valuable additional effects should be mentioned. First, Internet can help to preserve and share the cultural heritage. Second, communities in rural Africa become part of and thereby enrich the global community.
This paper describes the approach taken, the obstacles encountered (logistics, finance, durability of equipment in harsh conditions, regulation issues etc.), the lessons learned as well as the plans for next steps.
Bringing Internet connectivity to rural Zambia using a collaborative approach

In particular, if focuses on a proof-of-concept Internet service that has been implemented in rural Macha located in the Southern Province of Zambia. The service operates using satellite terminals (for connection to the Internet) and a wireless local area network. The provision of Internet access has enabled local health institutes to operate more efficiently and given local people the opportunity to communicate and explore new ideas. It has also created new employment opportunities and generated several projects including a data entry service and a sunflower farming initiative. Being a rural area, several problems hamper progress including frequent electricity outages and the exorbitant cost of bandwidth. International collaboration has been established between LinkNet, the Meraka Institute (South Africa), TNO (Netherlands) and the Global Research Alliance. With its partners, LinkNet addresses the main challenges through applied research and innovation and targets an upscaling of its activities throughout rural Zambia and beyond.
Traffic Characterization and Internet Usage in Rural Africa

Recent efforts have provided Internet connectivity to a growing number of remote locations, yet Internet traffic demands cause many of these networks to fail to deliver basic quality of service needed for simple applications. For an in-depth investigation of the problem, we gather and analyze network traces from a rural wireless network in Macha, Zambia. We supplemented our analysis with on-site interviews from Macha, Zambia and Dwesa, South Africa, another rural community that hosts a local wireless network. The results reveal that Internet traffic in rural Africa differs significantly from the developed world. We observe dominance of web-based traffic, as opposed to peer-to-peer traffic common to urban areas. Application-wise, online social networks are the most popular, while the majority of bandwidth is consumed by large operating system updates. Our analysis also uncovers numerous network anomalies, such as significant malware traffic. Finally, we find a strong feedback loop between network performance and user behavior. Based on our findings, we conclude with a discussion of new directions in network design that take into account both technical and social factors.
