Hey fellow geeks!
I finally registered after being passive for quite a few years in here!
Anyway, i was wondering if you could help me out with my limited knowledge

My client do software for media streaming over Wifi, and I have created an elaborate test/QA setup for all of their supported HW.
So-far, however, I have been doing testing over ethernet with DummyNet (network simulation) profiles for having a repeatable test situation.
I would like to extend this to testing over wifi as well and was wondering if some kind of "box" or "switch" exists that i could connect 10 or so wifi modules to via coaxial cable and they would interact as if it was in a perfect faraday cage?
In fact, I think i have seen something like this in a video about the production of Digi's XBee modules, but really cant find it now.
I don't know if this kind of gear exists off-the-shelf and i really don't know what to search for

Please post your thoughts!
