1. Signal Quality
Colour
Meaning
Green
16 QAM mode – maximum data rate
Amber
QPSK mode – reduced data rate
Red
BPSK – lowest data rate passing between nodes
White
Link broken or not configured
2. SNR Pane
3. Level A Pane
4. IP RX errors Pane
This gives a simple picture of the signal quality around the mesh system. Ideally, it would have
steady green boxes for all links. Naturally, mobile units will go out of range or interference will
cause a unit to degrade for a while.
The clever thing is the mesh will find a new routing and heal itself when it can, so keeping your
network on air.
Here’s what the colours mean:
Shows the dBm value for antenna A on a node. There are similar panes for antennas B, C and D.
This pane shows the number of IP receive errors for each node on the system.
This pane shows the Signal to Noise Ratios for each of the nodes. Typically SNRs > 15 is very good, 8
to 14 is good, 7 or less is starting to get low.
