Other than the fact that your APs lock up, what problem are you trying
to solve?
That's high on the list. Also...
* accommodate more users in larger rooms such as classrooms, auditorium,
conference rooms
* reduce the number of SSIDs; we now have one to six different SSIDs per
bldg
** allow roaming without client having to switch SSIDs
* separate guest & student traffic from faculty/staff (eventually...)
* improve coverage & tolerance of interference in certain problematic
locations
* (maybe) add some outdoor APs for special events
* centralize/simplify management and logging
Is this a wide-open network (like MIT used to have), is this something
for visiting guests to use, or do you intend for this to be only for
your employees?
It is presently wide open, which is why I haven't chimed in on the
RADIUS-vs.-whatever question much. I'll probably want to segment off a
staff-only SSID at some point but that's likely to be phase 2+.
do you have issues with coverage?
Yes in some areas. Many smaller buildings are small single-story wood
frame construction and one AP will cover 2-3 bldgs fine. Larger/newer
bldgs are steel frame and metal deck + concrete & rebar floors, so 1 AP
per floor now and we still have some dead spots, so I think that may
have to increase.
how many people do you expect to be using the wireless at any one time?
Typical usage will probably be about 20 per AP max. Classrooms could be
double that. Auditorium, maybe up to 100 during certain events.
what are they doing on the wireless? (using SSH to connect to servers
is vastly different than streaming HD video)
Nothing too brutal at the moment. Internet access, email, access to
file servers and application servers. Yep, even some SSH. Yes,
probably some video streaming and I'll wager that will increase with time.
I'm not in a position to re-engineer the whole campus at this time, but
I'm going to have to replace the access points in two of our larger
buildings (they just aren't cutting it) and I hope to select a system I
can build on as we move forward.
Thanks!
Roy
