Question

if the whole earth is to be connected by LOS communication using
space waves what is the minimum number of antennas required
calculate the tower height of these antennas in terms of earths
radius ​

Jossy Joseph · Accepted Answer

d^2 = 2(R + hr)^2
8Rh = 2(R + hr)2
(since d = 2(Rh)^1/2 )
4Rh = R^2 + hr^2 + 2Rh
(R - hr)2 = 0
R = hr
Since, space wave frequency is used, A
< < hr So, only tower height is taken
into consideration
Therefore, in three dimensions, 6 antenna
towers of hr = R would be required
R = hr
Since, space wave f< < hr So, only to into consideration
Therefore, in three dimensions, 6 antenna
towers of hr = R would be required
