7.4.1. Check whether the coverage is good
1. Take a test with a mobile phone or a data card (engineering mobile phone is preferred). If the signals in most areas
have not been improved, please check recommendations below again:
- Weak input signal leads to low output power. To increase input signal power level, change the direction of the
outdoor antenna or its installation position or replace it for an antenna with higher gain.
- Check whether it is necessary to use additional indoor antennas as barriers block signal penetration; also check
whether the repeater's power is enough; please install extra indoor antennas or replace the repeater for another
model with higher power level.
2. If the signals in small parts of the area have not been improved, please check the following:
- Check whether the indoor antenna is installed correctly or not; you may try to change the antenna location to
improve coverage.
- Check if it is necessary to adjust the direction of the indoor antenna.
- Check whether it is necessary to add one or more antennas to enhance the coverage in special areas.
Remark:
Reduce attenuation values * — by ensuring the isolation level
Increase output power * — recommended ways: to adjust outdoor antenna direction/location, or replace it to an
antenna with higher gain to increase input signal strength.
7.4.2. Repeater can not communicate in Power-ON status
1. The power is on but there is a signal fluctuation or a flash signal. The phone call cannot be made/received.
It shall be caused by the insufficient isolation between outdoor and indoor antennas.
Please take the following measures:
- Firstly check whether the alarm LED lights. Compare with the description from the 7.3. section The light may indicate
the isolation is insufficient.
