Note! To get parameters for 2G, 3G and LTE, disable WiFi. In case you cannot find Field Test Mode on your
cell phone, use bars on the screen of your mobile phone to evaluate the change.
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.
For maximum precision in signal level testing, switch your cell phone into Field Test Mode and see dB parameter. The
closer dB signal level to 0, the better cell phone reception you’ll get.
• -105 to -100 = Bad/drop call
• -99 to -90 = Getting bad/signal may break up
• -89 to -80 = OK/shouldn't have problems, but maybe
• -79 to -65 = Good
• Over -65 = Excellent
Your task is to get at least -79dB signal to ensure reliable communication and strong signal inside the building.
