I think the challenge here is that RF doesn't scale similarly to other mediums.

Cost per bit-mile on fiber is really low compared to RF.

If you assume 10G-LR optics (10km) @ $299 *2 (pair) + Cvt-5002sfp ($500*2)

is around $0.16/Mbit

RF (cheap) NB-5G25 = $95*2 (pair) is around $3.16/Mbit (assuming 60Mb/s unidirectional) or almost 20x the cost, assuming 40Mhz channel and spectrum available.

While fiber installation can be expensive, one needs to ask the local municipalities to install extra conduit every time the earth is broken for a local project.
