Before spending much time and money on 900MHz, I would suggest looking into any plans by Municipalities for deployment of 900MHz electric/gas/water metering.
Those systems are spectrum annihilators.

Not something ideal if you don't have the tower space. We are also using a notch filter that only allows in 900MHz ISM, it has helped quite a bit with some SCADA/Pager noise nearby.
