I was doing communications in military. For temporary networks, we used microwave links and they requires line of sight. The reason to use direct link is that missiles can be easily targeted to any radio source you can hear and take down the network.
- cogman10 2y agoYeah, I was aware of this because of work with telecommunications in rural locations. Nobody is burying a cable over a mountain, that's too expensive and too much work. So instead, they'll setup microwave towers. Being on a mountain has the benefit that you are already in elevated locations that are easy to shoot a phone signal across the range.
