Wireless bridging and VLAN

We currently have two buildings in a campus environment connected via T1.  We are looking to replace this T1 with wireless technology
from Cisco (the Aironet 1300 Bridges to be specific).  However, we are slightly confused as to how we will be able to retain our IP scheme.

Right now, one building is configured as a 10.1.1.0 network, and the other 10.1.9.0.  We would like to retain this configuration, but as the router
in one of the buildings is going away, we are unsure how to accomplish this.  Is this a suitable application for VLAN?  If so, how would we go about
setting this up?  We are using Powerconnect switches from Dell that support VLAN.

Couldn't you use the router in the other building?

VLANs allow you to create multiple segments out of one.  This has the effect of creating multiple IP networks for which you would need ... a router ... to connect them.  So, I don't think this is a suitable solution for VLANs.

You will either need:  A) A router to connect the two IP networks or B) change all the IP addresses in one location to match the network of the other.

I would either buy, or reuse, a router and connect it right behind your wireless bridge to connect the two nets.
