I've seen network quality indicators in several places expressed in some sort of decibel scale, and I presume that's what /proc/net/wireless contains as well:$ cat /proc/net/wirelessInter-| sta-|   Quality        |   Discarded packets               | Missed | WE face | tus | link level noise |  nwid  crypt   frag  retry   misc | beacon | 22wlp1s0: 0000   53.  -57.  -256        0      0      0      3   1001        0However, as someone not used to working with decibels, how do I interpret them? man procfs doesn't seem to have any relevant information.
How to interpret wireless quality indicators?
