That doc was worth the read ! It clears up my perception of RSSI now. The only gripe I have is why SB chose a rather coarse 40 step range instead of a 100 step range like cisco ? This is not a flame at SB just a question. I'm sure there is an answer. (Financial problely)
BTW my rssi plots using MRTG seem reasonable in percentage.
We do not have the accurate value. But you can refer to this doc http://www.wildpackets.com/elements/whitepapers/Converting_Signal_Strength.pdf for reference and understanding. Anyone has better source?

Does you have an accurate value of what the dBm should be when
getting 40 from the unit?? (like 20 30 40 whatever dbm?)

The RSSI display in percent will be more accurate to indicate how strong
the signal is. The internal formula to dbm conversion is not accurate
(eg.100% is -10dbm) and that is the reason we came out the option to
allow user to define their own conversion table. SO you can set like
100% equal to -45dbm, etc.. which is similar to other vendor dbm
reading.

Has there been a resolution to this yet? I just did an install that is
reporting a signal level of -10dbm.
The latest firmware allows you to punch in your own values for dbm
levels, but this hardly helps to provide an accurate measurement of
signal level.
