If “Absolute RSSI” value goes above -40 dBm, decrease Tx power at the opposite side
in order to keep it within -40...-50 dBm for the best performance.
Step 4 - Optimize the link performance
- Adjust Maximal link distance parameter based on the measured distance.
NOTE
Check measured link distance from the Status page and adjust the Max distance setting
by adding 200-300 m to the measured value.
- Monitor air block error rate by checking the Acc TBER parameter in the
Status page and adjust the AMC strategy if necessary.
