7.6. Master-Slave Distance
This is the physical distance between the Slave radio and the Master radio in the network.
Note: This distance is most accurate at a distance greater than 2.5 miles (4.0234 km).
7.7. Noise Level
The Noise Level indicates the level of background noise and interference at this radio and at
each of the Repeaters in the link.
The number is an average of the noise levels measured at each frequency in the radio’s frequency
hop table.
The individual measurement values at each frequency hop channel are shown in the frequency
table.
If viewing statistics in the terminal interface, press <Enter> when the Radio Statistics menu
appears.
See LRS455 Frequency Table (on page 100).
l Ideally, noise levels should be below -112 dBm.
l The difference between the average signal level and average noise level should be 26 or
more.
l Margins significantly higher than this are an indication of a high level of interference that
may degrade the performance of the link.
Use band pass filters, adjust the antenna placement, or use antenna polarization to
mitigate high noise levels.
7.8. Number of Disconnects
The value in the Number of Disconnects statistic indicates the total number of times the link
between the Master and the Slave has been lost and the radios lose Carrier Detect from the time
the radio is powered on until the radio is put into Setup mode.
l Under ideal operating conditions, the number of disconnects should be 0 (zero).
l One or more disconnects may indicate:
l a weak link,
l the presence of severe interference problems, or
l loss of power to any of the radios in the link.
Note: In Tool Suite, the disconnect information is available in the Summary View under Network
Diagnostics.
