8.6.2. Repeater can not communicate in Power-ON status
The power is on but there is signal fluctuation
1) The power is on but it has a signal fluctuation or a flash signal. The phone call can not achieved.
It shall be caused by the insufficient isolation between donor antenna and serve antenna,
Please take below measures:
Firstly check whether the alarm LED becomes red. The red light shows the insufficient isolation.
Secondly adjust the antenna directions or locations or enlarge the distance between them
Thirdly reduce the repeater’s gain by ATT DIP if the above methods don’t work
The best minimum distance between donor antenna and serve antenna should be more than 10
meters.
The following measures can also be tried:
Use the roof of the building to enlarge the isolation (Please try to place the donor antenna and
server antenna in different floors)
Use some obstacles.(Such as wall )
2) The repeater’s power is on but the phone is not connected into the network and still can not
communicate.
Reason 1:
There are loose or wrong connections in the repeater system.
Solution:
Please try to fasten the connections between the different parts of the system.
Reason 2:
The signals received by donor antenna of other operators nearby are too strong. (For
example, the other operators’ signals are 10 dB stronger than the needed signals.)
Solution 1:
Change the direction of donor antenna or its installation position, so that the gap of
signal strength between operators are reduced.
Solution 2:
Use barriers (like buildings) to block signals of other operators.
