Package: wavemon
Version: 0.4.0b-11
Severity: wishlist
Tags: patch
Some wireless cards report signal level in RSSI (Received Signal Strength
Indicator) instead of dBm. This is an arbitrary integer index, usually
ranging from 0 to 100 or from 0 to 255. See /proc/net/wireless.
Unfortunatelly this is not well handled by wavemon, which expects a value
in dBm, usually ranging from -110 to 20.
Drawing the levels histogram, the Minimum signal level and Minimum noise
level cannot be raised above -60 and this is very annoying because the
histogram is compressed to the top.
I suggest to raise the "item->max" from -60 to zero, both for conf->sig_min
and conf->noise_min.
A correct handling of RSSI levels would require certainly more work.

Hi,
I have consulted with upstream, and he believes that noise levels are
already balanced:
> * min noise level: -128 .. -60
> * max noise level: -60 .. 120
> * min signal level: -128 .. -60
> * max signal level: -59 .. 120
>
> The lowest maximum signal level is 1 dBm above the highest minimum
> noise level, allowing for an SNR of 1dBm.
>
> There is format conversion inside wavemon. I am not sure what the
> post means with RSSI, to my understanding this is the signal quality
> level which is separate from the dBm scale. It is represented as a
> separate bar, usually ranging from 0..70. In the scan window, it is
> converted to a percentage (i.e., 0..100).
Therefore, I am closing this bug report.
Thanks,
Jon
