Hi guys,
Inherited an Aruba Network at a School I work at and I have been slowly getting my head around the current deployment of AP61s and looking at upgrading to AP105s.
Scenario:
Main building
We have a large number (around 280) students who roam from class room to class room using laptops. The building is circular in design with 8 classrooms around a common open area.
Total area is 45m x 36m per floor
At any one time - we could have 1 class of 24 on that floor - or maybe 5 or 6 classrooms full with over a 100 users.
Deployment:
Currently 3 AP61's per floor
NO AIR MONITOR AP's
AP61's are not set to Arm Mode Aware
ARM mode is default
All AP61's are b/g
2 x 3400 Controllers
2 x 800 Controllers
Each controller performs DHCP and is allocated to a separate VLAN
Not ALL AP's in the same floor (or building are on the same Controller - hence VLAN)
IP Mobility is not enabled
Issues:
Patchy performance at best
Poor mobility
Thoughts / Suggestions:
Ensure all AP's on the same floor are provisioned to the same controller and hence VLAN
Increase the desnity of the AP's to ideally 1 per classroom (eg 1 per 24 users at peak usage)
Deploy 3 AM per floor
Considerations:
With such a high density deployment of AP61's in b/g mode - will the default ARM profile be able to manage channels and power - or should we switch to Mode ARM Aware?
I am concerned that with only 3 non overlapping channels and say 8 AP61s per floor we will get overlapping interference that ARM cannot handle
Should we instead move to manual power mgt? (cumbersome I know)
Is IP mobility required if clients are moving within the same floor building - hence on the same controller and same VLAN?
Point to note:
We have many legacy laptops that do not support a hence staying on b/g but I guess the same questions may still apply if we move to the 105's.
Any advice on the above is much appreciated!
I have learnt a lot on these forums this weekend (as well as reading 100's of pages of manuals!!) - but just want to see if I have the general picture correct.
Cheers
Wally
