    Publication Year: 1990, Page(s):177 - 182
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (372 KB)

    The low numbers of subscribers in rural areas and the long distances between communities pose a number of problems in providing modern telecommunication facilities. These are often compounded by adverse climates and inhospitable terrain. Overcoming these problems requires a global solution combining compatible transmission, switching, and distribution facilities to optimise telecommunication netwo... View full abstract»
