Apologies if this is posted elsewhere but I cannot find it and the AP documentation does not explain it.

I just want to understand how the DLink RSSI percentage values relate to real db values.  The reason for the question is that I am trying to tune the RSSI Aging out and ACL values so one AP does not hang on to the mobile devices longer than it should before handing to another. I am basing my numbers on the following assumptions:

db >= -50 db = 100% quality
db <= -100 db = 0% quality

For RSSI signal between -50db and -100db,
quality ~= 2* (db + 100)
RSSI ~= (percentage / 2) - 100

For example:
High quality: 90% ~= -55db
Medium quality: 50% ~= -75db
Low quality: 30% ~= -85db
Unusable quality: 8% ~= -96db

As this is a residential installation I have the transmit power turned down to 25% for 5GHz and 12.5% for 2.4GHz on all the AP's.

Thanks for any advice.
