I have recently deployed a WLAN within a building (using AP125's), having surveyed for good SNR and generally only using a "coverage" model, and a sparse AP deployment. The result so far has been that 60%-70% of the AP's have turned into Air Monitors. I was hoping for about 10% (but ideally 0%).
I want to keep the current survey and deployment methodology, so will need to tweak our ARM settings. So far though, I've not discovered any real information to assist with coming up with the correct ARM settings (bar trial and error). I've read the basic stuff, but still have no idea what "coverage index" in need to be able to offer, say, -67dBm or more to my clients on 2.4 GHz.
So, as such - I would be grateful if anyone has any in depth info, or experiences to share to assist with this process.

Before considering turning it off, I want to try and make sure it's the best call. In principle the ability to turn off G radios is useful.
I was hoping that as the sites in question were surveyed to ensure high SNR, that ARM would not feel the need to turn AP's off. As this was not the case, my second approach is to try and find out what it is that is causing the AP's to choose to become AM's. (Consider, it's *possible* that ARM is correct, and preventing high levels of interference from somewhere and the survey is wrong)
Failing anything else, I will need to look at turning Mode Aware off.
