signal strength is traditionally measured in either percentile or
dBm (the power ratio in decibels of the measured power referenced
to one milliwatt.) By default, CommView for WiFi displays the
signal strength in dBm. The level of 100% is equivalent to the
signal level of -35 dBm and higher, e.g. both -25 dBm and -15 dBm
will be shown as 100%, because this level of signal is very high.
The level of 1% is equivalent to the signal level of -95 dBm.
Between -95 dBm and -35 dBm, the percentage scale is linear, i.e.
50% is equivalent to -65 dBm.
measurements in percentile are preferable, you can switch to
percentile by using the Display
signal level in dBm option in Settings =>
Options => Decoding. When Display
signal level in dBm is turned on, the signal
strength will be shown in dBm on the Nodes,
tabs. In the
packet decoder tree, the level is always shown in both percentile
