One more add:
Properly engineered, fixed wireless links can have better-than-wireline
availability. Two jobs ago, we had customer links with zero dropped
packets in 5 years, which is outstanding compared to most copper-based
services.
Properly engineered, however, is the key. Make sure whom-ever is building
your links looks at vendor specs, builds a real link budget (including
losses from connectors, cable, grounding, etc) properly weather seals
everything, and try to get at least a a 20db fade margin if you can. If
the things I just mentioned are confusing to your RF guy, you might want
to get outside help.
