In August last year I spent two weeks helping on a project delivering internet connectivity within the Bunda and Serengeti regions of Tanzania. The project, run by a Tanzanian group called ICT for Rural Development (ICT4RD), is identifying the most appropriate and sustainable technical solutions for use in delivering connectivity to rural Tanzania, so as to work out the best technical design as a model to roll out across the country.
The project is partnered with the Dar es Salaam Institute of Technology, The Tanzanian Commission for Science and Technology, and the Swedish International Development Agency.
The project initially links up schools, health centres, hospitals and council offices over 150 km into the Serengeti between Bunda, Natta and Mugumu, providing Internet connectivity and Voice over IP between these locations. The next phase of the project is to attract commercial customers, who are willing to pay for the connectivity thus making it economically sustainable.
The principle behind the technical design of the project is sharing a single satellite internet link between multiple users, therefore sharing the cost and making it more affordable. The cost of a satellite link is the most expensive operational cost in providing internet connectivity to remote areas. For example, Bunda Teaching Training College was paying around $400 a month for its satellite connection, but found this too expensive, and was going to have to shut it down or ask students to fund it out of their pockets. The ICT4RD solution now provides Internet connectivity to the college at a fraction of the cost.
