Liberty University has been doing multicast over WLAN for years for IPTV with
our Aruba infrastructure.
I am not sure what you mean by VLAN groups, but we make extensive use of user
roles in Aruba's built-in stateful firewall.
If you are using VLANs for security, you are doing it wrong!
Nothing to do with security... instead of an SSID mapping to a single VLAN (and
we don't do role-based VLANs) we map to an interface group of 4 VLANs. That's
where that question came from.

Looking to hear about anyone doing above ceiling AP installations and see how
the coverage compares to below the ceiling. I also don't have much time or
resources to play around with the design since it will be in a hospital
environment.
I am pushing to keep the AP's below the ceiling but the
We have done both above ceiling and below ceiling and found that it
depends what's above the ceiling. Ductwork, pipes, etc. affect about 10%
of our coverage. We have also tested the newer in-the wall devices
that could be applicable to your design. We chose Ruckus since a number

Thank you Chuck. This is how I see it as well. As the deployment gets more
dense with AP’s walls become less of a factor. My other big resistance to this
is serviceability. In a Hospital we have Infection Control issues. You can’t
just get a step ladder and start poking around trying to
Agreed. I was thinking along these lines as well. If your walls are not
“floor to floor” above the ceiling Auto RF will have a clear shot to all the
other AP’s.

Can you tell us the brand/model for their patient/equipment location tracking
system?
Thanks.

Near my home, Kaiser just completed a new state-of-the-art hospital and for the
patients, it’s has a very luxury feel to it. They’ve deployed Cisco for
wireless (for public and private), and the AP’s are all below the ceiling,
along with what appear to be cellular repeaters. Having the AP’s

a lot of the information about it.

The question for me isn’t really whether to or not above the ceiling work
or not, it’s how predictable is it. Coverage from AP’s, be they above or
below the ceiling, is highly influenced by obstacle near the AP. For the
most part, there are more potential obstacle above the ceiling than below.
Above ceiling installation with auto RF mechanisms like TPC can cause lower
power settings when the walls do not go above the ceiling. We have many
additions throughout our campus where the walls do not extend above the grid.
An AP placed above that will behave much differently than expected.
We did a survey about 5 years ago using AirMagnet and found that we lost 10-15%
by going above the ceiling. The only difference between the two tests was the
½ to 3/4” of the thickness of the ceiling tile.
I was much happier with the Aps mounted on the wall were we could see them and
