Troubleshooting
(1). Input donor signal is too weak.
(2). RxQual of donor signal is originally bad.
(3). Adjacent-channels or Co-channels were
introduced by the repeater system.
(4). Self-oscillation occurs.
(1). Increase input signal level by re-orientate or re-locate
donor antenna. If possible, the alternative way is to
change the orientation of BTS antenna
(2). Re-orientate or re-locate donor ant. in order to find
another donor signal. The alternative way is to contact
the engineer of operator to fix the BTS problem.
(3). Re-orientate or re-locate donor ant. and try to increase
the ratio C/A or C/I (To let the major signal as stronger
as possible, and make the adjacent-channel or co-
channel signals as weaker as possible).
(4). Isolation is possibly insufficient, and the alarm of “AGC”
(Over AGC range) shall light. Try to increase the
separation between service ant. and donor ant.
