We have our own fixed wireless, pair of Ubiquiti AirFibre 24's connecting 2 buildings about 1/2 mile apart, on towers @50ft. So far even during electrical storms we have had NO issues with dropped packets or sync loss, even with tower sway in the winds. Now, our past winter was not as snowy as a normal winter so I am not sure yet how it will behave when we get one of our infamous lake effect storms but so far absolutely no issues. Key was having a professional radio company actually do the installation and line up of the dishes where they had 1 guy on each tower and 1 ground guy at each site to assist with line up.
Locally, we have a fixed wireless ISP that offers traditional Internet, MPLS, and IPVPN services. I know one of the service/operations managers there and he says most issues be traced to bad alignment of the antenna (wind over time twists the mounts causing mis-alignment) or customers not getting enough height (rather not PAYING for enough height) to clear limitations like trees. Works well in the winter when no leaves, but come spring and summer the leaves deflect the signal and speeds drop. Any fixed wireless needs an annual look-see to make sure clamps are still tight and alignment is still ok.
