7.4. System Test
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).
To test signal level with a cell phone, make use of its engineering mode (Field Test
Mode), which is an application available in free access or a phone mode requiring no
extra setups. On most used mobile OS (operating systems) the test mode can be started
as follows:
◦ iOS. Type *3001#12345#* and hit Call
◦ Android. Type *#*#197328640#*#* to activate
◦ Windows. Type ##3282# and start.
◦ Blackberry. Press TOOLS, SETTINGS, STATUS or OPTIONS, STATUS.
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.
