ARM Good Practices for Classroom Use

Has anyone come up with ARM settings that work well in a high density environment such as 1 (Aruba 125) AP in every 20'x30' classroom?

Re: ARM Good Practices for Classroom Use

You should be good to go with the defaults. If you are getting too much coverage into other rooms you might want to tune the max power in ARM to a lower number. If you are on 3.3.2 check out some of the new ARM 2.0 features that are talked about in "Aruba ARM Release Notes Supplement.pdf" under ArubaOS 3.3.2 documentation on the support site. A lot of my school customers have turned on Band-Steering to move the 5Ghz clients off of the 2.4Ghz radio.

Yes, I'm running 3.3.2. but I've segregated the bands so that the teachers use 2.4Ghz and students use 5Ghz so Band-Steering won't work for me.

My biggest issue is that ARM isn't load balancing the client load as it did when I demoed it last year. Even though the 125s are providing enough bandwidth to support 15 to 30 clients at a time, but sometimes authentication takes longer than the patience of a teenager will allow. ;)

ARM Good Practices for Classroom Use

In that same "Aruba ARM Release Notes Supplement.pdf" it talks about
Spectrum load balancing. You can also find some good information on it
in the roaming devices design guide, page 23 (config on page 47). Is
that what you are using? Or are you load balancing under the RF
Optimization profile? Some clients keep requesting the same AP no matter
how many times we tell them to move to a weaker RSSI AP. We end up
letting them on the AP we are trying to lighten the load on so they are
not denied service.
