Design and installation of rural telecommunications networks : lessons from three projects

This report documents the specifics of the design, installation, and operation of the three systems and related technology, as well as lessons learned from the experience. Program results show that the idea is sound, the technology can be developed, and the costs are reasonable. In addition, the challenges of developing countries" financial, technical, and human resource limitations led to innovations in such areas as: satellite bridging to conserve channel use; a network "gating" system to reduce line noise; the first-time use of a six-meter earth station with INTELSAT domestic service; the design of a small, solar-powered earth station for rural use; specially adapted equipment to withstand humidity; and new graphics systems. The program has given both A.I.D. and the host countries the technical ability to help others establish innovative uses of satellite technology, sparing them the arduous trial and error technology transfer process. Extensive diagrams, figures, and pictures illustrate the report.
