How well does Siklu handle rain at closer to 1mi. range?

We use primarily Dragonwave (in FCC part 101 frequencies: 11, 18, and 23GHz), 
which can get ~600-800Mbpas over the air, depending primarily on channel width 
and distance. For shorter links (~1 mile), we use Siklu 80GHz, which can do 
1-2Gbps over the air.

You might be better served with the lists over at wispa.org. Not saying the 
people here don't have the answers, but that's what those guys do.

In a context of providing rural communities with modern broadband.

Reading some tells me that Microwave links can be raised to 1gbps. How
common is that ?

I assume that cell phone towers have modern microwave links (when not
directly on fibre). What sort of capacity would typically be provided ?

And in the case of a remote village/town served by microwave originally
designed to handle just phone calls, how difficult/expensive is it to
upgrade to 1gbps or higher capacity ? Just a change of radio ? or radio
and antenna, keeping only the tower ?

(keeping spectrum acquisition out of discussion as that is a whole other
ball game).

Sometimes you have two or more MMRs sometimes providers are only one one
or another.

The actual discipline here is delivering reliable cost-effective service
with unreliable components...
