The Mode 3 display shows the signal to noise ratio (SNR) at the
location you are testing. Signal refers to the signal strength of the
incoming message from the wLSN Hub to the Installation Tool.
Noise refers to the ambient noise level that exists at the location.
The signal must be greater than the noise (S>N). The higher the
SNR is, the stronger the location’s signal is at that location. Refer
to Table 4.
In the Mode 3 display “SNR yy” refers to the signal to
noise ratio in dB and “x” is the RFSS value in dBm.
Dashes, appearing on both the S and N lines, indicate
unacceptable signal strength.
