We've got a building that we "own", but have various tenants.  We have one
tenant that is located across the street, but we have a local connection, so
have set up a mobility anchor with them from our controller to their
controller.  We broadcast their wi-fi, but everything tunnels back to them -
Association, Authentication, IP addressing, routing, etc.  The other
tenants, we've managed to keep a visitor SSID (captive portal, accept
policy, get online), and a generic 802.1x SSID that goes to a different
radius server than the campus students/staff/faculty authenticate against.
Once we do eduroam campus wide, we'll be at 6 SSID's, and that's really the
most I want to do (more than, really).

Subject: [WIRELESS-LAN] Multi-tenant wireless question

We have an interesting design problem that I thought I would toss out for
ideas.  Using 1042 and 1602 APs with a single 7510 controller.

We have two of our companies sharing building space (the spaces are
inter-mingled, not separate suites), however they have separate routers and
ISPs and they are not routed between each other back at our core.

I can cover the space with 3 wireless access points, but I need to have
different SSIDs and keep their wireless completely separate, connected back
to each companies respective routers.

My current best option is to deploy 6 APs (3 for each) and use RF profiles
to keep them from turning their power down too low since each pair will be
10 feet apart or so.  This also costs me twice as much.

Another option we are tossing around is connecting a cable between the two
router/switch setups to allow us to map the SSIDs to a VLAN on each router.
This causes future support issues though and if this connecting cable is
every moved (very likely to happen) it could cause issues.  Also, all the
authentication/management traffic would go out one of the routers, so if
that one goes down, the other company loses their wireless as well.

Anyone have any creative ideas?
