IIRC Bridgewave has a 100 mbps solultion for less than $8k?

If you need less than 100mbps and 5-9 reliabilty, you are better off in
all factors and comparisons, staying with Licensed 18Ghz or 23Ghz or
24Ghz.
It will cost less, and be less risk of future maintenance.

E_Band has all sorts of reflection problems. For example, "rain puddle"
can cause a harmful reflection.
Do not push the path study limit of Eband or FSO, or you'll be sorry.
1.2 km is pushing the specs, of the cost effective models of those
product lines.
(PS. but opinion based on my D2 rain zone)

If you NEED faster speeds than 300mbps, and have Short links with
conservative link budgets, Eband/FSO will work fine.
