James: Have you considered setting up a single WLAN for the building (staying with a 3 channel model) and use VLANs to set up separate WLAN segments for both institutions?

We've agreed to go to the four non-overlapping channel model instead of three. Each institution will use two channels. This is my first shot at full building coverage and foresee channel interference issues as I'm restricted to two instead of three channels. Presumably, this can be addressed with directional antennas and adjustment of signal strength but I thought I might ask more experienced folks who might have already experimented with channel interference. If two APs operating on the same channel can 'hear' each other, is it simply a throughput hit or do things just not work at all? Presumably, there's a relationship to how close the APs are to each other (signal strength-wise)...'closer' means more interference? Also, the amount of traffic is a factor as well? This particular building has a central open area surrounded by offices/classrooms with glass windows overlooking the open space. The signal seems to easily penetrate the glass and cover the open space as well.....ie....I have multiple APs operating on the same channel bleeding into the open space. Is this a show-stopper for the open space or is it possibly a slow but liveable scenario? ....advice or comments are greatly appreciated. ......thanks in advance.........Jamie James Savage York University Senior Com.
