4.1.6. Signal Quality
This gives you a simple picture of the signal quality around the mesh system. Ideally, we‟d
like to see 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. One of the clever things about the mesh
is its ability to find a new routing and heal itself thus keeping your network on air.
Here‟s what the colours mean:
Colour
Means…
Green
16 QAM mode – most robust
Amber
QPSK mode – less robust
Red
Basic link only – lowest data rate passing between
nodes
White
Link broken or not configured
Note that a Red link will not guarantee IP data between nodes.
For example the link between node 0(TX) and node 4(RX) is currently Amber.
4.1.7. SNR
This pane shows the Signal to Noise Ratios for each of the NETNodes. For good quality links
this should be in excess of 17dB.
4.1.8. Level A
This pane shows the dBm value for antenna A on the NETNode unit.
4.1.9. Level B
This pane shows the dBm value for antenna B on the NETNode unit.
