Hi,
In one of our sites, we have 10 AP-105's in close proximity to each other i.e. approx 12 feet apart. These are also wallmounted, rather than ceiling, they are also mounted approx 12 feet above the floor. This is a school deployment and the close proximity is due to each AP being in each classroom, if you were to take away each classroom dividing wall, then each AP would be 12 feet apart along the same wall (the walls are quite thin too).
My question is; if some of the APs become air monitors ("Mode Aware Arm" is enabled) does this mean there is too much interference or does it mean there is enough spare capacity to allow these APs to become air monitors? or could it possibly be either? I have noticed that 2 or 3 become air monitors but as I am new to Aruba I am not sure how to check why it is doing this.
Just one more thing if someone would be kind enough to comment; If we don't do physical site surveys or use RFPlan (or VisualRF), would I be correct in assuming that blindly deploying APs on the assumption of 1 AP per classroom, and leaving everything to the controller to sort out is not a good way to do deployments? I know that ARM can make adjustments to compensate for things, but am I right to think that bad AP positioning can make things worse? I ask this as someone else had already deployed the APs and that is the methodology that they used i.e. guesswork.
Hopefully that makes sense
Cheers
