[c-nsp] Max number of users on Aironet 1252AG

[A.L.M.Buxey at lboro.ac.uk]

hi,

around 30 users per wifi channel on the AP - eg
30 on 802.11a, 30 on 802.11b/g  is the reasonable
value per AP - thats for 1242, 1131, 1252 etc.

the wireless controller doesnt have a limit as
such for number of users - especially if you DONT
use it as the captive portal etc and just use
it to control the APs (use a seperate Linux box, for
example, as a captive portal).  however, it DOES
have a limit on the number of APs it can support -
decided by a licence.

if you are talking about 4000 concurrent users then
I'd immediately state you want at least 8 subnets
with 510 users in each - eg /23's from a /16 class B 
private...as that wireless is going to massively
swamped by broadcast activity - especially with 
windows laptops... 16 /24's might be even better..however
mobility between APs would then get interesting.
