Troubleshooting
Problem
The signal booster has no power.
The booster's power is on but the phone is not
connected to the network and still cannot
communicate with the signal.
Good downlink signal with poor communication
quality.
The power is on but the coverage is not good.
Eliminate Alarm LED Quick Flashing and RED problems:
▲
Adjust the outdoor antenna direction, keeping it away from the indoor antenna. Restart
booster.
▲
Increase the vertical or horizontal distance between the outdoor antenna and indoor
antenna. Restart booster.
▲
Use barriers such as walls to increase the isolation.
▲
Change the indoor antenna type to an antenna with a more directional antenna pattern.
Orient the indoor antenna and outdoor antenna so they point in opposite directions.
▲
Reduce the booster's downlink gain using the manual gain controls. Keep the uplink gain
value and downlink gain value the same, then restart the booster.
Note: Uplink gain must be equal to or not less than 5dB below the downlink gain, to avoid
interference with the local carrier's cell site network.
Target: This situation refers to ISO issue and if issue resolved, the Alarm LED would show
Green light UP status.
Eliminate poor coverage problems when gain or output power value abnormal in Sub-
Band Interface:
If the signal has not been improved, please check below:
•
The weak downlink signal leads to the low output signal level. Change the direction or
•
position of the outdoor antenna. You may also try replacing the outdoor antenna with a higher
gain antenna to increase the incoming signal.
Check to see if it is necessary to add more indoor antennas. Barriers such as walls can
•
block the signal indoors. You should also check the booster to make sure the power is
maximized. Try installing more indoor antennas or replace the booster with a higher powered
one.
Solution
Check that the AC outlet is working.
Try to fasten the connections between the different
parts of the system.
Change the direction of the donor antenna or its
installation position.
Check whether there's interference.
Consult the operator whether the signal source base
station works well.
Check Alarm LED indications. Take the actions
mentioned below.
