Interference sensitivity

5.3.1.

Co-channel interference sensitivity

The limits of the co-channel interference sensitivity are shown in Table 5-12, referred to point C. The
table shows maximum and typical C/I values for 1 dB and 3 dB increase of the 10

Adjacent channel interference sensitivity

The limits of the adjacent channel interference sensitivity are as given in
Interference Sensitivity
