Read this overview:

I think this describes some technologies that could be applicable for your case.

Subject: [fw-wiz] Discretionary WiFi Access

Its not firewall related, but there's some smart minds on this list.
My company has started looking into campus-wide WiFi. I'll keep my personal
feeling on this to myself though. One thing that keeps comming up is that
one of the largest user communities that would take advantage of this would
be non-employees. Vendors, Salesmen, people meeting with GMs/VPs/Execs are
probably going to be the main users of this. My question is, if you
currently have a similar situation in your work environment, how do you
handle granting these people temp/guest WiFi access.

Access controls for employees can be fairly stringent (i.e. only connect
from company owned assets who's MAC is inventoried, use of 2 factor
authentication, etc), but a lot of this isnt applicable for temporary
visitors. I know one company that would give you a WiFi card when you signed
in that was in their database of 'allowed' MAC addresses (I know, dont get
me started on MAC spoofing), however I would bet cash money that those cards
walked away regularly. Similar thing with issuing a temporary token fob
(SecureID or the like).

I know the easy answer here is 'Dont give them WiFi access', but I don't
think that is going to be an option. Thoughts, comments, flames?
