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 number of antennas required? Calculate the tower height of these antennas in terms of earth’s radius?

LOS – Line of Sight

In LOS communication the transmitter and receiver must place in a distance and at a height to visible to each other. Then only there will be a transmission of data. Otherwise the data cannot be transmitted through this LOS communication system.

If we are considering the whole earth is connected to a LOS system.

Our earth just like a sphere.

So in case of sphere there will be a possibility of 6 antennas
