Autonomous or LWAPP for fast roaming

Guest

We are looking to deploy wifi to support Tablet PCs. The software we
are using is very sensitive to loosing its connection to the SQL
database. I am worried particually about roaming. We need to use 802.1x
for security and would like to use the MS IAS servier with EAP-TLS for
authentication. We have 4 locations which should each be well covered
by 3 base stations at each location. Medical providers need to be able
to move around the office without losing connections. Time is more
important than money. An hour of lost provider time (and when our app
crashes it crashes hard) is worth avoiding with addition money. My
questions are the following:

1. Do we need LWAPP or will autonomous with WLSE work for us?
(Specifically for fast secure roaming, or quick handoff, or whatever it
is we need)

2. Do we need to use EAP-FAST (and thus a Cisco AAA server) or will
EAP-TLS with IAS be enough?

3. If we use LWAPP do we need WCS or will managing each 2000 series
WLAN controller be enough?

4. Will all this work with my HP switches and Andtran routers?

Hello,

here are a couple of thoughts and considerations: have you already made
your choice regarding the hardware you will be using for your AP's and
your tablet PC's ? Since it is connection stability that you are
looking for, I would try and stay with the same manufacturer as much as
possible. So, if you are looking at Cisco AP's, WLSE in combination
with EAP-FAST and WCS would be recommendable. EAP-TLS with IAS requires
server and client digital certificates, while EAP-FAST lets you use
Windows password logon, not sure if that is of any consideration.
Since you say that you have already deployed HP switches and AdTran
routers, leaving the Cisco equipment out alltogether would be
recommendable. Or, obviously, replacing the HP and AdTran with Cisco
routers and switches, which is a question of how much money you have to
spend...
How far are you with the planning of your wireless network ? Do you
have WiFi support already in place for devices other than the tablet
PC's ?

Well, we tried out HP 420 APs for a few weeks and were never able to
get it to be very stable. So we are looking at the Cisco solution
because of all the advanced features availalbe. As far as going to
Cisco switches, I think that is out of the question for now.
