I want to know the unit in which The Signal
is calculated. Is it in dBM ? Usually I see the dBM values are in -
. What would the -
and +
values signify in dBM ? Also more the value is positive, does it mean more Signal Strength ? i.e would a value of 42
mean higher signal strength than a value 37
?
