Test Results Tab
The Test Results tab is your primary screen to analyze link test results using the
following indicators:
! Signal to noise radio (SNR)
! Received messages
Signal to Noise Ratio (SNR)
The signal to noise ratio (SNR) identifies the communications quality of radio
path between your station and the link test partner. This indicator is updated
dynamically according to the actual status of the radio link.
The color of SNR indicator relates to the following levels of communications
quality.
If the level of SNR is lower than expected the signal level and noise level
indicators may help you investigate the cause:
! A low signal level indicates that the “strength” of the radio signal is fairly
low: i.e. your Client Manager station is almost ‘out-of-range’ of its link test
partner.
! A high noise level indicates a source of radio interference in the radio path
between the two link test partners.
Comparing the values for your station and the link test partner will help you
to identify the location where the interference occurs, and investigate
whether any actions to eliminate or remedy the source interference
resulted in a better performance.
Received Messages
The indicator “Received Messages” provides a way to determine the efficiency
of the radio path between your Client Manager station and the link test partner.
When running a link test, your Client Manager station will exchange messages
with its test partner. The test partner will confirm proper receipt by returning
an acknowledgment response.
Both your wireless station and the link test partner will use these messages to:
! Measure the signal to noise ratio (SNR).
Color Description
Green Communication quality is “Excellent” or “Good”, no intervention is required.
Yellow Communication quality is “Marginal”, no intervention is required.
Red Communication quality is “Poor”, intervention required. (see Appendix B:
Troubleshooting on page B-1)
