In the old days, outdoor fixed wireless was primarily used for one simple yet powerful application – point to point (PTP) cell site backhaul. As cellular technology improved and capacities increased, so did the point to point gear you used to connect the towers. Yet the deployment of these links remained fairly vanilla connecting point A (the tower) to point B (the wireline PoP). The backhaul link was cited on the same tower as the RAN, making site acquisition and power supply simple. These links were typically in the licensed microwave bands from 7GHz up to 38GHz and were deployed as one offs.
