Just to clarify this for people who don't know the EE details of this. Even direct point-to-point fiber suffers compared to microwave because of the velocity factor of the cables. What?! Inside a glass fiber, the speed of light is only about 70% the speed of light in free-space! Microwave in air, though, travels very very close to the free-space velocity of light.
