. A Country’s Government has approved a relocation plan for a section of its population to inhabit a 3-island portion. Design a hypothetical Telecommunication network(Fixed and mobility consideration) for both internal and external communication.
Consider the following
1. Islands location is 5000km from the main land
2. Islands are equidistant from one another
3. Accessibility by water transport
4. Government very resourceful – enough money
5. A lot of economic activity on the Islands (billions of dollars annually)
6. 1.5 million population with 80% adults
7. 120-kilometre bridge links the three islands
