for wireless backhaul of cell-towers, some wisp infrastructure and for
this like inter-building point-to-point connectivity. pretty common.

an example would be something like

well if you're describing at&t longlines or bell canada C-band microwave
relay networks those were built a time when cost was not the primary
consideration, (e.g. there were not signficant alternatives in the 1950s

modern radios are dramatically cheaper. use of unii bands or licensed
spectrum are options, distance and spectrum choices tends to dominate
the set of considerations that goes into selecting a system.
examples of unlicensed being something like
