If the whole earth is to be connected by LOS communication using space waves ( no restriction of antenna size or tower height), what is the minimum no of antennaas required ? Calculate the tower height of these antennas in terms of earth's radius?

Explanation

To solve the problem of connecting the whole Earth using line-of-sight (LOS) communication with space waves, we will follow these steps:

### Step 1: Determine the Minimum Number of Antennas Required
To cover the entire surface of a sphere (the Earth), we need to consider the geometry of the situation. A common approach is to use the concept of a geodesic dome or a polyhedron that can approximate a sphere.

For a sphere, the minimum number of antennas required to ensure coverage is typically 6. This is because 6 antennas can be positioned at the vertices of an octahedron, which can effectively cover the entire surface of the Earth.

### Step 2: Calculate the Height of the Antennas
