Yes, this is the point. I dont always have a spectrum analiser to measure my dBm signal nor similar hardware, so I would like to have this information for each associated host in my freebsd access point, even if it is not fully accurate, since no software that does this, in fact is. I need something similar to what kismet can give me, but this kind of software (kismet, dstumbler) to give some reasonable useful information puts the interface in scan mode, and it is useless to me since all associated hosts will drop its association. So I wrote a program to converte from RSSI to other values, dBm or %. I just need a good formula now :-) specially for atheros On 9/27/06, Pete French <petefrench@ticketswitch.com> wrote: > > Is this paper's information accurate regarding atheros? > > I have no idea - I think you would be best off calibrating it yourself > with a dBm metre if you can.
