Use VSATs to build, restore or expand a data network Network build, restoration and network growth using VSATs and Eutelsat W3 satellite at 7 deg East longitude. Overloaded terrestrial links need additional capacity immediately, pending terrestial upgrade. New remote nodes need connecting quickly, pending terrestrial provision. New links may only be required temporarily and capacity required is speculative.
Growth is required in small increments.
In the event of satellite capacity being required between sites, a 'data call' is set up and capacity provided immediately, at whatever bit rate, for as long as required. The VSATs will be typically 1.8m diameter at most remote sites but perhaps 2.4m or 3.8m diameter at main traffic nodes or at the outer edge of the satellite beam coverage.
