Abstract [en]

We present research on how to establish sustainable broadband markets in rural areas of developing regions. Due to an increasing political awareness of the importance of ICT for development, many such regions are now being networked. Since they have little legacy to consider, there are opportunities to leapfrog and stimulate solutions tailored to future needs and public good. The specific properties of the network topologies discussed are due to the piecemeal deployment of optical fiber creating broadband islands to be connected via whatever narrowband links available. The quality of service in such networks of interconnected broadband islands can be optimized by making the broadband islands self-sustained and managing the narrowband links by clever use of bandwidth management schemes, buffering, caching, etc., tailored to the needs of the specific services and applications. Our strategy assumes an open access regulatory regime allowing sharing of communication resources, opening up for innovative business models and new value chains. It calls for new technical solutions, also considering power consumption and cost . Our research includes experimental validation, currently focusing on two pilots in rural Tanzania, having one of the most open regulatory frameworks in Sub-Saharan Africa. The paper discusses a network design and outlines experiments underway in the pilots.

Abstract [en]

The problem discussed in this thesis is how to establish sustainable broadband markets in under-served areas. The purpose is to improve people’s living conditions by promoting efficient service delivery in education, health, and governance and alleviating poverty. Due to the high-perceived risks, the market forces have failed to bring ICT in these areas. The business community is reluctant to take on the supplier role.

Earlier efforts through development partners have been focusing on connecting under-served areas to the global Internet via telecentres. However, most implementations could not operate beyond the initial funding for various reasons, especially the lack of understanding of the local needs where most technical solutions were imported from the developed world, not optimized to work under local conditions.

We propose the creation of community or municipal owned “broadband islands”, defined as high speed communication broadband networks that do not depend on external connections for their operations. Using an Action Research participatory approach, we are emphasizing multi-stakeholder partnerships, and engaging the local community to contribute infrastructure, technical solutions and leadership. Our proposal is validated through the design and deployment of two pilot sites in rural areas of Tanzania. Our original contributions include 1) An overall model on how to establish and sustain broadband markets in under-served areas, making it scalable and reproducible. 2) technical innovations, especially the design and implementation of a low cost, low power-consuming, and robust router with integrated power management. 3) Organizational innovations by establishing institutional mechanisms at a local level in public-private-community partnership. 4) Innovative funding mechanisms by identifying partners who can pay on behalf of the end users and cut down costs through resource sharing schemes.

The government of Tanzania has shown interest to use the pilot sites as models for extending the national backbone into other municipal. Also, discussions are underway to organize similar pilots in East Africa.
