I'm fairly new to this... but the only sure-fired system I can think
of would be to use the Tranzeo Radios a the 900 MHZ band.
(http://www.tranzeo.com/products/radios/TR-902-Series )

I have a similar setup here running a distance 1600 meters. I get
great signal and about 9 mb/sec downloads.

You'd need one at each end.
The downside is that you can't do it for less than $600. But that is
a very good price considering similar equipment.
