Customer is looking at about 800 7925s across a campus, they mentioned having a single 7925 voice vlan (10.x.x.x/16) across all Wireless LAN Controllers (4400s) for the whole campus for these 7925s.This doesn’t sound good having all 7925s on same subnet across multiple buildings.
What are others doing as the Enterprise Mobility Guide 4.1 doesn’t give much thought.
it is interesting to note that by default broadcasts are not allowed and anyway not carried between wireless clients. So the usual argument against having big subnets doesn't hold for wireless clients.
This said, I would also be for smaller subnets. One per building is usually something good. One per floor is not a good idea as clients often roam to APs on other floors and we want to avoid inter-vlan roaming as much as possible for simplicity's sake. So I'd vote for the "1 vlan per building".

This is the start of a display filter cross reference between Wireshark and OmniPeek.
The 1st installment is a table of advanced filters. More filters will be added as time allows.

The script should be completely self explanatory.
