Measurement key figures

Link margin (LKM)

The link margin (LKM) indicates which reserve is still in the reception quality. The LKM value is calculated from the measured RF values. It is a modulation-independent value that summarizes the RF quality of a digital signal in a number in dB.

The link margin indicates by how many dB the signal may deteriorate until error-free reception is no longer possible.

Link margin (LKM in dB)
Must > 0
Should > 5
Ideal > 10
