Testing Radio Communications Quality
5
The primary indicator to monitor is the communications quality of 
the radio connection. This value is expressed in a Signal to Noise 
Ratio (SNR). The SNR indicator will change color in the range 
‘Green, Yellow and Red, according to communications quality 
result as identified below:
When the SNR is rated as “Good” or “Adequate” the performance 
of your WaveLAN station will be good as well. 
When SNR is rated “Poor” you may need to consider one of the 
options proposed by the WaveMANAGER/CLIENT tool. 
To access WaveMANAGER/CLIENT tips for troubleshooting click 
the “Advice” button. Advice may include:
Optimizing antenna placement to increase the WaveLAN 
Signal Level, or
Eliminating sources of interference to decrease the Noise 
Level that affects the Signal to Noise Ratio (SNR).
Use the indicators for Signal Level and Noise Level to determine 
the cause of reduced performance. The panels for “Your Station” 
and the “Link Test Partner” will help you to identify where you 
should start “optimizing antenna placement” or “eliminating 
interference”.
Color
Description
Green
Communication quality is “Good”.
No intervention is required.
Yellow
Communications quality is “Adequate”. 
No intervention is required.
Red
Communications quality is “Poor” and requires user-
intervention (see Appendix B ”Troubleshooting”)
