The cost of the internet in rural Africa can be substantial. Joseph explains how he shares the cost of the VSAT (the satellite that provides his internet) with other organizations in his community, thereby making it possible for him to have the internet while also connecting an agricultural NGO and a secondary school to the internet, as well as a business. This has become a standard business model for rural internet in Africa, but few telecentres have been able to sustain it, mostly because they haven't learnt how to provide the service themselves and they can't afford to pay for someone to come and install or maintain the equipment. The key, it would seem, is having someone who can figure out how to install this gear. Joseph later explains that resources like the Wireless Networking in the Developing World book have been essential to him being able to support this system.
