Check whether it is necessary to add one or more antenna to enhance the coverage of special
areas.
Remark:
Reduce the attenuation values*
---at the same time must ensure the isolation
Increase the output power*
---recommended ways: adjust the donor antenna; increased
input signal strength.
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
Test coverage
1) Mobility Service antenna
2) increase the number of service
antenna
3) reduce the attenuation values
4) increase the output power
