Table 4 Mse Expected And Maximum Values - Trango Systems TrangoLINK GigaPlus User Manual

Interference can come from other transmitters on the tower, as well as from sources
inside an indoor shelter. High power transmitters inside a shelter can cause interference
when near the PoE device or when located very close to the cabling.
There are maximum acceptable MSE values for each modulation which are useful in
determining the quality of the link. The MSE value reported is only relevant to one tx-rx
path, so the MSE of each tx-rx path must be evaluated to verify the link is operating as
expected. The lower the number the better, so a -35dB is better than a -30dB. The table
below shows the maximum MSE value to expect in IF Loopback, Normal Operation, and
Absolute Maximum.
