There are four numbers of interest, Signal, Noise, SNR, and Signal Quality. Signal quality is expressed as a percentage. For instance the first line shows the series -42 -88 46 64% The received signal level -42 dbm The receiver noise level -88 dbm Signal to noise ratio 46 Signal quality 64% I did not create the system, I am merely a user but that's is how I interpret it.
