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.
•
If the signal in a small section of the building hasn't been improved, try the following:
•
Check to see if the indoor antenna is installed correctly. Try moving the antenna to
improve coverage.
•
Try adjusting the direction the indoor antenna is pointing.
Remark:
•
When increasing the downlink gain, make sure the isolation is adequate to prevent system
oscillation
Note: The Alarm LED long-term Green up and the problems of self-oscillation and strong
downlink signals are fixed. In most cases, there is no need to take any additional measures
except for deep self-oscillation or excessively strong signals from the tower. The self-adaptive
ALC and isolation gain processing system automatically solve most problems.
Check Alarm LED indications. Take the actions
mentioned below.
