Thanks jow!

Yea it's quite debatable. At the moment our values are quite not right
http://map.ninux.org (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.

Maybe... could that range be restricted?

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.

The reason for which I ask you guys is because I'd like to hear opinions
and experiences from other wireless communities ^_^
