Microwave link capacity

Agree with Mike that WISPA is probably the place to get real world experience from people who make a living with microwave links.

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).
