<pre wrap="">the Kernel uses RSSI values between -110 and -40 to calculate its
"signal quality", the formula is simple:
quality = min(max(rssi, -110), -40) + 110
That gives 70 quality levels, divided by your three color choices gives
ca. 23 dB spans, so it would result in:
-110 .. -87 -> red
-86 .. -64 -> orange
-63 .. -41 -> green

Thanks jow!<br>

Yea it's quite debatable. At the moment our values are quite not
right <a class="moz-txt-link-freetext" href="http://map.ninux.org">http://map.ninux.org</a> (click on dBm on the right column).
We'd like to have values that are more useful in order to have a
quick overview of the network.<br>
<br>
Maybe... could that range be restricted?<br>
<br>
I guess a link that is worse than -90 does not have much sense. I
don't know if there is a very noticeable difference in performance
between a -50 and a -40 link, anyway, links with those values
happen rarely in our network, only if two nodes are very very
near. I checked now (Info tab in upper right corner) and we have
only about 10 links in that range of dBm values out of 132.<br>
<br>
The reason for which I ask you guys is because I'd like to hear
opinions and experiences from other wireless communities ^_^<br>
